This application makes use of the following technologies running on JBoss AS EJB 3.
JBossCache 2. A traditional tree-structured node-based cache and a PojoCache, an in-memory, transactional, and replicated cache system that allows users to operate on simple POJOs transparently without active user management of either replication or persistency aspects. JBoss Transactions is the default transaction manager for JBoss 5. JBoss Transactions is founded on industry proven technology and 18 year history as a leader in distributed transactions, and is one of the most interoperable implementations available.
See the Detailed Release Notes section for the full details. It allows innovation at a faster pace. Fueled by the thriving JBoss. JBoss Enterprise Middleware further mitigates risk with industry leading 24x7 support and multi-year update and maintenance policies. This means you have an enterprise-class open source option for application and service hosting, content aggregation, data federation, and service integration — for both development and production.
JBoss Enterprise Application Platform is a rigorously tested, stable, supported platform for developing and deploying mission critical Java applications and services. It integrates code from the JBoss. The need to reduce operational costs.
With zero licence fees you can refocus savings on business differentiation. Jboss Mitigates risks and helps customers avoid vendor lock in. You can therefore start new projects without any cost prohibition. You can use the Application Server with other middleware such as Hibernate and Websphere. With Red Hat open source Assurance program the code is always there and not dependent on a single vendor.
You can consistently meet service level agreements SLA's with as little change as possible by back porting patches to previous versions. With 24x7x support with 1 hour SLA you are guaranteed support when you need it. Performance tuning and certification services are also available to our customers. Automated patch and upgrade management on JBoss Enterprise middleware increases reliability of resources with minimal downtime if any. If using a Sun Java 6 runtime, you may want to set -Dsun.
Those are now included in a new artifact, jboss-ejb3-ext-api. Use of JBoss Cache 2. JBC 2. The following diagram illustrates an overview of the JBoss.
The directory structure of JBoss 5 resembles that of the 4. Deploying applications on JBoss AS is very easy. You can replace default with different server profiles such as all or minimal. We will cover those later in this chapter. JBoss AS constantly scans the deploy directory to pick up new applications or any changes to existing applications.
So, you can "hot deploy" application on the fly while JBoss AS is still running. The WAR application archive e. It contains servlet classes, view pages, libraries, and deployment descriptors such as web. The EAR application archive e. The SAR application archive e. It is mostly used by JBoss internal services. That allows you to make changes to web pages etc on the fly without re-deploying the entire application. If you do need to re-deploy the exploded directory without re-start the server, you can just "touch" the deployment descriptors e.
The JBoss Application Server ships with three server configurations. You can choose which configuration to start by passing the -c parameter to the server startup script. For instance, command run. You can look into each server configuration's directory to see the default services, applications, and libraries supported in the configuration.
The minimal configuration starts the core server container without any of the enterprise services. It is a good starting point if you want to build a customized version of JBoss AS that only contains the services you need. The default configuration is the mostly common used configuration for application developers.
It supports the standard J2EE 1. The all configuration is the default configuration with clustering support and other enterprise extensions. The detailed services and APIs supported in each of those configurations will be discussed throughout this book.
JBoss Application Server 5. If you need additional services then you can simply deploy these on top of Java EE to provide the functionality you need. Likewise you are free to remove any services that you don't need simply by changing the configuration. You can even use the microcontainer to do this in other environments such as Tomcat and GlassFish since you can plug in different classloading models during the service deployment phase.
This opens up new possibilities for mobile applications that can now take advantage of enterprise services without requiring a full JEE application server. In common with other lightweight containers JBoss Microcontainer uses dependency injection to wire individual POJOs together to create services.
Configuration is performed using either annotations or XML depending on where the information is best located. Finally unit testing is made extremely simple thanks to a helper class that extends JUnit to setup the test environment, allowing you to access POJOs and services from your test methods using just a few lines of code.
This section introduces the various Microcontainer modules. The figure below gives an overview of the modules. The container module contains: reflection, the integration point for manipulating class information at runtime, e. The controller is the core component for keeping track of contexts to make sure the configuration and lifecycle are done in the correct order including dependencies and classloading considerations.
The managed module defines the base objects defining the management view of a component. The metatype metatype module defines the base types found in the management view of a component.
The configuration files have comments to guide you on the specific configurations available as illustrated by the example below. ProfileService : this bean loads the deployments associated with the named server profile, "default", "all" or whatever name is passed in as the "-c" option to the server.
Its an extension of the jboss Deployer aspects are registered with the MainDeployer as an ordered list via inject of the deployers property. JARDeployer : this bean is a structural deployment aspect which handles the legacy nested deployment behavior of adding non-deployable jars to the current deployment classpath. It handles the legacy jboss-service.
It is used by the SARDeployer. It will be used by other management deployment aspects in the future to expose kernel beans via JMX.
HDScanner : a bean that queries the profile service for changes in deploy directory contents and redeploys updated content, undeploys removed content, and add new deployment content to the profile service. Web services are a key contributing factor in the ways Web commerce is conducted today. A web service is essentially a software application that supports interaction of applications over a computer network or the world wide web. Web services usually interact via XML documents that map to an object, computer program, business process or database.
To communicate, an application sends a message in XML document format to a web service which sends this message to the respective programs. Responses may be received based on requirements and the web service receives and sends them in XML document format to the required program or applications. Web services can be used in many ways examples include supply chain information management and business integration among a multitude of other applications. Enterprise systems communication may benefit from a wise adoption of WS technologies.
Exposing well designed contracts allows developers to extract an abstract view of their service capabilities. Considering the standardized way contracts are written, this definitely helps communication with third-party systems and eventually support business-to-business integration. No more agreement required on vendor specific implementation details, home-brew communication protocol or custom per-customer settings. Everything is clear and standardized in the contract the provider and consumer agree on.
Of course this also reduces the dependencies between implementations allowing other consumers to easily use the provided service without major changes.
Enterprise system may benefit from web service technologies also for internal heterogenous subsystems communication. As a matter of fact their interoperability boosts service reuse and composition.
No more need to rewrite whole functionalities only because they were developed by another enterprise department using another software language. In case you think you already heard something like this Transforming an enterprise business to Service Oriented Architecture includes obtaining standardized service contract, service reusability, service abstraction, service loose coupling, service composability and so on.
Of course SOA is an architectural model agnostic to technology platforms and every enterprise can pursue the strategic goals associated with service-oriented computing using different technologies. However in the current marketplace, Web Services are probably the technology platform that better suits SOA principles and are most used to get to this architecture.
Needless to say that web services are not the solution for every software system communication. Nowadays they are meant to be used for loosely-coupled coarse-grained communication, for message document exchange.
Finally web service specifications also include notion of registries to collect service contract references, to easily discover service implementations, etc. This all means that the web services technology platform suits complex enterprise communication and is not simply the latest way of doing remote procedure calls.
WS-I Attachment Profile 1. The most simple way to enable SwaRef encoding for DataHandler types is to annotate a payload bean with the XmlAttachmentRef annotation as shown below:. The related specifications are. The above table shows a list of supported endpoint parameter types. The recommended approach is to use the javax.
DataHandler classes to represent binary data as service endpoint parameters. The only Java type that can easily cope with this ambiguity is javax. XOPTestCase :. With document style web services two business partners agree on the exchange of complex business documents that are well defined in XML schema. For example, one party sends a document describing a purchase order, the other responds immediately or later with a document that describes the status of the purchase order.
No need to agree on such low level details as operation names and their associated parameters. Document is defined by the style attribute on the SOAP binding. With document style web services the payload of every message is defined by a complex type in XML schema. Bare is an implementation detail from the Java domain. Neither in the abstract contract i. A bare endpoint or client uses a Java bean that represents the entire document payload.
The trick is that the Java beans representing the payload contain JAXB annotations that define how the payload is represented on the wire. Wrapped is an implementation detail from the Java domain. A wrapped endpoint or client uses the individual document payload properties. Wrapped is the default and does not have to be declared explicitly. With RPC there is a wrapper element that names the endpoint operation.
Child elements of the RPC parent are the individual parameters. The SOAP body is constructed based on some simple rules:. With rpc style web services the portType names the operation i. WebResult respectively. It has inherent interoperability issues that cannot be fixed. The Basic Profile Specifically, JBossWS does not support JAX-WS simplifies the development model for a web service endpoint a great deal.
In short, an endpoint implementation bean is annotated with JAX-WS annotations and deployed to the server. The server automatically generates and publishes the abstract contract i.
Let's take a look at simple POJO endpoint implementation. All endpoint associated metadata is provided via JSR annotations. A successfully deployed service endpoint will show up in the service endpoint manager.
This is also where you find the links to the generated wsdl. Above you see an EJB Packaging the endpoint. Accessing the generated WSDL. Note, it is also possible to generate the abstract contract off line using jbossw tools.
However, in some cases it is desirable for services to be able to operate at the XML message level. Note, Service. You can also use Service. The WebServiceContext is treated as an injectable resource that can be set at the time an endpoint is initialized. The WebServiceContext object will then use thread-local information to return the correct information regardless of how many threads are concurrently being used to serve requests addressed to the same endpoint object.
Service is an abstraction that represents a WSDL service. A WSDL service is a collection of related ports, each of which consists of a port type bound to a particular protocol and available at a particular endpoint address.
For most clients, you will start with a set of stubs generated from the WSDL. One of these will be the service, and you will create objects of that class in order to work with the service see "static case" below. Static case. Most clients will start with a WSDL file, and generate some stubs using jbossws tools like wsconsume.
This usually gives a mass of files, one of which is the top of the tree. This is the service implementation class. The generated implementation class can be recognised as it will have two public constructors, one with no arguments and one with two arguments, representing the wsdl location a java.
URL and the service name a javax. QName respectively. Usually you will use the no-argument constructor. These are set implicitly from the WebServiceClient annotation that decorates the generated class. Section Dynamic Proxy explains how to obtain a port from the service and how to invoke an operation on the port. Dynamic case. In the dynamic case, when nothing is generated, a web service client uses Service. This is the nastiest way to work with JBossWs.
Older versions have extensive details on DII as it was then known. Handler Framework describes the handler framework in detail. When a Service instance is used to create a proxy or a Dispatch instance then the handler resolver currently registered with the service is used to create the required handler chain. Subsequent changes to the handler resolver configured for a Service instance do not affect the handlers on previously created proxies, or Dispatch instances.
Service instances can be configured with a java. The executor will then be used to invoke any asynchronous callbacks requested by the application. The setExecutor and getExecutor methods of Service can be used to modify and retrieve the executor configured for a service. You can create an instance of a client proxy using one of getPort methods on the Service. The service endpoint interface SEI is usually generated using tools. A generated static Service usually also offers typed methods to get ports.
These methods also return dynamic proxies that implement the SEI. The WebServiceRef annotation is used to declare a reference to a Web service. It follows the resource pattern exemplified by the javax. Resource annotation in JSR . To define a reference whose type is a generated service class. In this case, the type and value element will both refer to the generated service class type. If the type cannot be inferred, then at least the type element MUST be present with a non-default value.
To define a reference whose type is a SEI. The wsdlLocation element, if present, overrides theWSDL location information specified in the WebService annotation of the referenced generated service class.
WebServiceRef Customization. In jboss These include. The Dispatch interface provides support for this mode of interaction. Dispatch supports two usage modes, identified by the constants javax. Message In this mode, client applications work directly with protocol-specific message structures. Message Payload In this mode, client applications work with the payload of messages rather than the messages themselves. Dispatch is a low level API that requires clients to construct messages or message payloads as XML and requires an intimate knowledge of the desired message or payload structure.
Dispatch is a generic class that supports input and output of messages or message payloads of any type. The BindingProvider interface represents a component that provides a protocol binding for use by clients, it is implemented by proxies and is extended by the Dispatch interface. BindingProvider instances may provide asynchronous operation capabilities.
When used, asynchronous operation invocations are decoupled from the BindingProvider instance at invocation time such that the response context is not updated when the operation completes.
Instead a separate response context is made available using the Response interface. Oneway indicates that the given web method has only an input message and no output. Typically, a oneway method returns the thread of control to the calling application prior to executing the actual business method.
The handler framework is implemented by a JAX-WS protocol binding in both client and server side runtimes. Proxies, and Dispatch instances, known collectively as binding providers, each use protocol bindings to bind their abstract functionality to specific protocols. Client and server-side handlers are organized into an ordered list known as a handler chain.
The handlers within a handler chain are invoked each time a message is sent or received. Inbound messages are processed by handlers prior to binding provider processing.
Outbound messages are processed by handlers after any binding provider processing. Handlers are invoked with a message context that provides methods to access and modify inbound and outbound messages and to manage a set of properties. Message context properties may be used to facilitate communication between individual handlers and between handlers and client and service implementations. Different types of handlers are invoked with different types of message context. Handlers that only operate on message context properties and message payloads.
Logical handlers are protocol agnostic and are unable to affect protocol specific parts of a message. Logical handlers are handlers that implement javax. Handlers that operate on message context properties and protocol specific messages. Protocol handlers are specific to a particular protocol and may access and change protocol specific aspects of a message. Protocol handlers are handlers that implement any interface derived from javax. Handler except javax. An absolute java.
URL in externalForm. For example, a handler may use the put method to insert a property in the message context that one or more other handlers in the handler chain may subsequently obtain via the get method. All properties are available to all handlers for an instance of an MEP on a particular endpoint. There is currently no portable way of doing this in 4.
WebServiceContext injection will be available with 4. In the meantime you can access the message context like this:.
Logical Handlers are passed a message context of type LogicalMessageContext when invoked. LogicalMessageContext extends MessageContext with methods to obtain and modify the message payload, it does not provide access to the protocol specific aspects of amessage. A protocol binding defines what component of a message are available via a logical message context. In case of the latter JBossWS generates the required fault wrapper beans at runtime if they are not part of the deployment.
It currently doesn't support an external binding configuration. JAXB Introductions. Both come with or without MTOM flavours:. MTOM enabled service implementations. MTOM enabled clients. With document wrapped endpoints you may even specify the XmlAttachmentRef annotation on the service endpoint interface:. If you chose the contract first approach then you need to ensure that any element declaration that should use SwaRef encoding simply refers to wsi:swaRef schema type:.
First we will look at server-side development strategies, and then proceed to the client. When developing a Web Service Endpoint the server-side you have the option of starting from Java bottom-up development , or from the abstact contract WSDL that defines your service top-down development.
If this is a new service no existing contract , the bottom-up approach is the fastest route; you only need to add a few annotations to your classes to get a service up and running. However, if you are developing a service with an already defined contract, it is far simpler to use the top-down approach, since the provided tool will generate the annotated code for you. Replacing the implementation of an existing Web Service, and you can't break compatibility with older clients.
Exposing a service that conforms to a contract specified by a third party e. Used for bottom-up development. Consumes the abstract contract WSDL and Schema files , and produces artifacts for both a server and client. Used for top-down and client development.
The bottom-up strategy involves developing the Java code for your service, and then annotating it using JAX-WS annotations. These annotations can be used to customize the contract that is generated for your service. For example, you can change the operation name to map to anything you like. However, all of the annotations have sensible defaults, so only the WebService annotation is required. The WSDL, and all other Java artifacts called "wrapper classes" will be generated for you at deploy time.
This actually goes beyond the JAX-WS specification, which requires that wrapper classes be generated using an offline tool. The reason for this requirement is purely a vender implementation problem, and since we do not believe in burdening a developer with a bunch of additional steps, we generate these as well.
However, if you want your deployment to be portable to other application servers, you will unfortunately need to use a tool and add the generated classes to your deployment. Additionally, it can be used to "provide" the abstract contract WSDL file for your service.
This can be obtained by invoking wsprovide using the "-w" option:. Remember that when deploying on JBossWS you do not need to run this tool. This will internally invoke wsprovide , which will generate the WSDL. For a portable JAX-WS deployment, the wrapper classes generated earlier could be added to the deployment. The top-down development strategy begins with the abstract contract for the service, which includes the WSDL file and zero or more schema files.
The wsconsume tool is then used to consume this contract, and produce annotated Java classes and optionally sources that define it. Using the WSDL file from the bottom-up example, a new Java implementation that adheres to this service can be generated. The "-k" option is passed to wsconsume to preserve the Java source files that are generated, instead of providing just classes:.
Examining the Service Endpoint Interface reveals annotations that are more explicit than in the class written by hand in the bottom-up example, however, these evaluate to the same contract:. The only missing piece besides the packaging is the implementation class, which can now be written, using the above interface. Before going to detail on the client-side it is important to understand the decoupling concept that is central to Web Services.
Web Services are not the best fit for internal RPC, even though they can be used in this way. Web Services were designed specifically for interoperable coarse-grained correspondence. There is no expectation or guarantee that any party participating in a Web Service interaction will be at any particular location, running on any particular OS, or written in any particular programming language. So because of this, it is important to clearly separate client and server implementations.
The only thing they should have in common is the abstract contract definition. If, for whatever reason, your software does not adhere to this principal, then you should not be using Web Services.
For the above reasons, the recommended methodology for developing a client is to follow the top-down approach , even if the client is running on the same server. Let's repeat the process of the top-down section, although using the deployed WSDL, instead of the one generated offline by wsprovide.
The reason why we do this is just to get the right value for soap:address. This value must be computed at deploy time, since it is based on container configuration specifics. You could of course edit the WSDL file yourself, although you need to ensure that the path is correct.
Using the online deployed version with wsconsume :. The one class that was not examined in the top-down section, was EchoService. Notice how it stores the location the WSDL was obtained from. While you can use Service directly, this is far simpler since it provides the configuration info for you. The only method we really care about is the getEchoPort method, which returns an instance of our Service Endpoint Interface.
Any WS operation can then be called by just invoking a method on the returned interface. It can then be easily executed using the wsrunclient tool. This is just a convenience tool that invokes java with the needed classpath:. This section describes how WS-Addressing can be used to provide a staful service endpoint.
Web Services Addressing 1. The following endpoint implementation has a set of operation for a typical stateful shopping chart application. On the client side there are simmilar handlers that does the reverse.
A client connecting to the stateful endpoint. SOAP message exchange. WS-Eventing specifies a set of operations that allow an event consumer to register subscribe with an event producer source to receive events notifications in an asynchronous fashion. WS-Eventing specification. WS-Addressing Specifications. An event sink web service client sends a subscribtion request to the event source endpoint.
This includes the event sink endpoint address where notifications should delivered. Upon successful subscription the sink receives a leased subscription ID that can be used to identify the client in subsequent requests.
A successfully registered event sink directs management requests Renew, GetStatus, Unsubscribe to the subscription manager endpoint using the previously received subscription ID.
The subscription manager endpoint address was returned as part of the subscription response in the first place. JBossWS-Eventing dispatches the notification to any subscriber endpoint that is registered with a particular event source.
This can be the case when the subscription expired or the event source was undeployed. It is the users responsibilty to supply the web service endpoints EventSourceEndpoint, SubscriptionManagerEndpoint that are required for a complete event source deployment.
Create a custom WSDL that describes your event source, in respect to the notification schema 1 and the fact that is actually contains an event source port 2.
All you need to do is to subclass your endpoint implementation from AbstractEventSourceEndpoint and a subscription manager from AbstractSubscriptionManagerEndpoint and finally point that implementation to a event source specific WSDL. Subclass a predefined implementation that knows how to delegate to the actual eventing service implementation. Example notification. It can be accessed through the jmx-console.
Management operations exist to monitor and maintain active subscritions and deployed event sources. The current implementation is backed by a ThreadPoolExecutor, that asynchronously delivers messages to event sink endpoints. It can be configured through the following attributes:. WS-Security addresses message level security. It standardizes authorization, encryption, and digital signature processing of web services. Unlike transport security models, such as SSL, WS-Security applies security directly to the elements of the web service message.
This increases the flexibility of your web services, by allowing any message model to be used point to point, multi-hop relay, etc.
Username Token Profile 1. Basic Security Profile 1. JBossWS uses handlers to identify ws-security encoded requests and invoke the security components to sign and encrypt messages. In order to enable security processing, the client and server side need to include a corressponding handler configuration. You need to setup both the endpoint configuration and the WSSE declarations. That's two separate steps. In this example we configure both the client and the server to sign the message body.
Both also require this from each other. So, if you remove either the client or the server security deployment descriptor, you will notice that the other party will throw a fault explaining that the message did not conform to the proper security requirements. This specifies that the store password is "jbossws". Please see samples for their usage. This specifies that the trust store password is also "jbossws". Here we start our root config block.
The root config block is the default configuration for all services in this war file. This means that the server must sign the message body of all responses. Type means that we are to use a X. Here we start our optional requires block. This block specifies all security requirements that must be met when the server receives a message. By default an endpoint does not use the WS-Security configuration. Use the proprietary EndpointConfig annotation to set the config name.
The root config block is the default configuration for all web service clients Call, Proxy objects. This means that the client must sign the message body of all requests it sends. This block specifies all security requirements that must be met when the client receives a response. We did not specify a key store or trust store, because client apps instead use the wsse System properties instead. If this was a web or ejb client meaning a webservice client in a war or ejb jar file , then we would have specified them in the client descriptor.
Below you see the incomming SOAP message with the details of the security headers ommited. The idea is, that the SOAP body is still plain text, but it is signed in the security header and can therefore not manipulated in transit. The information below has originaly been provided by The Legion of the Bouncy Castle. The provider can be configured as part of your environment via static registration by adding an entry to the java. You'll find detailed instructions in the file but basically it comes down to adding a line:.
Where you put the jar is mostly up to you, although with jdk1. Under Windows there will normally be a JRE and a JDK install of Java if you think you have installed it correctly and it still doesn't work chances are you have added the provider to the installation not being used.
This technology will be present within the JBoss Transactions 4. Further information can be obtained from the JBoss Transactions Project. J2EE 1. Starting jboss The configuration of this service can be done in the jboss-service.
Database Tables Should they be created on start, Should they be dropped on stop, Should they be dropped on start etc. The System properties that are needed are:. Then you will need to pass the System properties in the run.
When the client code is running in an external JVM. Then you can pass the properties either as "-D" options to the java process or explicitly set them in the client code not recommended. A registry client can get this interface from a Connection to a registry. It provides the methods that are used by the client to discover various capability specific interfaces implemented by the JAXR provider.
Note that there is no authentication information provided, because the Connection interface keeps that state and context on behalf of the client. It is also referred to as the focused query interface. I cannot connect to the registry from JAXR.
I cannot connect to the jUDDI registry. Please check the jUDDI configuration and see if there are any errors in the server. And also remember that the jUDDI registry is available only in the "all" configuration.
I cannot authenticate to the jUDDI registry. Have you added an authorized user to the jUDDI database, as described earlier in the chapter? Please use the tcpmon tool to view the messages in transit. WS-Policy defines a base set of constructs that can be used and extended by other Web services specifications to describe a broad range of service requirements and capabilities. Current JBoss implementation can instrument a webservice with policies attached at endpoint, port or port-type scope level only.
There are two different methods to attach policies: providing a wsdl decorated with policies and policy attachments as defined by specifications, or using JBoss proprietary annotations. The first way has the advantage of being standard, while the second one is much more simple to implement. Of course the wsdl generated by these annotations conforms to standard defined in specifications and can be used with any ws-policy compliant client.
Please note that ws-policy specifications only define policy requirements and their attachment method to wsdl through specific extensions. It is out of the scope of ws-policy specifications and thus implementation to define and use the content of assertions. The way these assertions called domain assertions or domain policies have to be deployed and used is left to other specification like WS-Security-Policy or more generally to domain specific implementation.
To attach policies in this manner, the only thing you have to do in a webservice class is to provide a custom wsdl. This will cause JBossws to skip wsdl generation at deploy time, since the wsdl file you provided will be published. Please refer to specification WS-Policy-Attachment to learn how to modify wsdl to attach a policy.
Here you find an example of a webservice class and provided wsdl with a policy containing a domain assertion for JBoss wssecurity. Using JBoss proprietary annotation you only have to provide the policy xml, leaving wsdl generation to the JBossWS deployer.
There are two annotations to use, the first one PolicyAttachment containing an array of the second one Policy : this lets you have many policies attached to a class or method. In future domain policy implementations might ship domain annotations extending the Policy annotation to provide needed metadata directly as annotation parameters.
The current Policy annotation takes a reference to a xml file containing a generic policy description written respecting ws-policy specification rules. And here you have the previous section example re-implemented using annotations and xml policy file:. Common features and properties.
MainDeployer : this interface defines the contract for the MainDeployer. The MainDeployer handles parsing of deployment archives into Deployment instances and deployment of those instances into the microcontainer. Deployers are registered with the MainDeployer as an ordered list of deployers. MainDeployer contains two sets of deployers:. For each StructureDeployer the determineStructure DeploymentContext method is invoked to analyze the deployment. A StructureDeployer returns true to indicate that the deployment was recognized and no further StructureDeployer should analyze the DeploymentContext.
Deployers used to translate a DeploymentUnit into runtime kernel beans when the MainDeployer. The Deployer methods are:. This is still in progress. The org. VFSClassLoader is the current simple implementation. MainDeployerImpl implementation of the org.
MainDeployer interfaces, includes the following standard method details:. DeploymentContext getDeploymentContext String name : obtain the DeploymentContext associated with the given name from all of the DeploymentContexts that have been added to the MainDeployer. This includes top level and all child contexts. If the structural analysis succeeds, the DeploymentContext is added for deployment during process.
Next, the top-level DeploymentContexts that have been added are deployed by invoking commitDeploy on each deployer. The details of the deployment process are that each deployer is run on top-level context DeploymentUnit by invoking Deployer.
AbstractDeployer - simply stubs out isRelevant to return true and getRelativeOrder to return Integer. AbstractSimpleDeployer - essentially collapses the Deployer contract to deploy DeploymentUnit and undeploy DeploymentUnit by stubbing out:.
AbstractClassLoaderDeployer - implements org. ClassLoaderFactory, and deploy DeploymentUnit u as u. The deploy implementation obtains a deploymentType metadata from the deployment unit and then delegates deployment to visitor. Undeploy similarly delegates to visitor. Undeploy similarly invokes super. The component visitor is expected to create DeploymentUnit components DeploymentUnit.
The helper methods added include:. The result is added as an attachment to unit. This is parsed into deploymentType T by calling parse unit, file, document. The xml document must have a valid schema with JBossXB annotations. Aspects allow you to more easily modularize your code base when regular object oriented programming just doesn't fit the bill. It can provide a cleaner separation from application logic and system code.
It provides a great way to expose integration points into your software. Combined with JDK 1. JBoss AOP is not only a framework, but also a prepackaged set of aspects that are applied via annotations, pointcut expressions, or dynamically at runtime.
Some of these include caching, asynchronous communication, transactions, security, remoting, and many many more. An aspect is a common feature that's typically scattered across methods, classes, object hierarchies, or even entire object models. It is behavior that looks and smells like it should have structure, but you can't find a way to express this structure in code with traditional object-oriented techniques.
For example, metrics is one common aspect. To generate useful logs from your application, you have to often liberally sprinkle informative messages throughout your code. However, metrics is something that your class or object model really shouldn't be concerned about. After all, metrics is irrelevant to your actual application: it doesn't represent a customer or an account, and it doesn't realize a business rule. It's simply orthogonal. A joinpoint is any point in your java program.
The call of a method. The execution of a constructor the access of a field. All these are joinpoints. You could also think of a joinpoint as a particular Java event. Where an event is a method call, constructor call, field access etc It could contain information like which method is being called, the arguments of the method, etc An advice is a method that is called when a particular joinpoint is executed, i.
It could also be thought of as the code that does the interception. Another analogy is that an advice is an "event handler". Pointcuts are AOP's expression language. Just as a regular expression matches strings, a pointcut expression matches a particular joinpoint.
An introduction modifies the type and structure of a Java class. It can be used to force an existing class to implement an interface or to add an annotation to anything.
An Aspect is a plain Java class that encapsulates any number of advices, pointcut definitions, mixins, or any other JBoss AOP construct. An interceptor is an Aspect with only one advice named "invoke".
It is a specific interface that you can implement if you want your code to be checked by forcing your class to implement an interface. In AOP, a feature like metrics is called a crosscutting concern , as it's a behavior that "cuts" across multiple points in your object models, yet is distinctly different.
As a development methodology, AOP recommends that you abstract and encapsulate crosscutting concerns. For example, let's say you wanted to add code to an application to measure the amount of time it would take to invoke a particular method. In plain Java, the code would look something like the following. The profiling code really doesn't belong sprinkled throughout your application code. If you wanted to expand this functionality to include a method or failure count, or even to register these statistics to a more sophisticated reporting mechanism, you'd have to modify a lot of different files again.
This approach to metrics is very difficult to maintain, expand, and extend, because it's dispersed throughout your entire code base. And this is just a tiny example! In many cases, OOP may not always be the best way to add metrics to a class. Aspect-oriented programming gives you a way to encapsulate this type of behavior functionality.
It allows you to add behavior such as metrics "around" your code. For example, AOP provides you with programmatic control to specify that you want calls to BankAccountDAO to go through a metrics aspect before executing the actual body of that code. In short, all AOP frameworks define two things: a way to implement crosscutting concerns, and a programmatic construct -- a programming language or a set of tags -- to specify how you want to apply those snippets of code.
Under JBoss AOP, the Metrics class wraps withdraw : when calling code invokes withdraw , the AOP framework breaks the method call into its parts and encapsulates those parts into an Invocation object. The framework then calls any aspects that sit between the calling code and the actual method body. When the AOP framework is done dissecting the method call, it calls Metric's invoke method at line 3. Line 13 obtains contextual information about the method call from the Invocation object, while line 14 displays the method name and the calculated metrics.
Having the metrics code within its own object allows us to easily expand and capture additional measurements later on. Now that metrics are encapsulated into an aspect, let's see how to apply it. To apply an aspect, you define when to execute the aspect code. Those points in execution are called pointcuts. An analogy to a pointcut is a regular expression. An entry point could be a field access, or a method or constructor call.
An event could be an exception being thrown. Some AOP implementations use languages akin to queries to specify pointcuts. Others use tags. JBoss AOP uses both. Listing Three shows how to define a pointcut for the metrics example. Lines define a general pointcut that applies the metrics aspect to all methods in all classes in the com. There is also an optional annotation mapping if you do not like XML. See our Reference Guide for more information.
You can attach your aspects to a specific Java class in your application or you can use more complex compositional pointcuts to specify a wide range of classes within one expression. With AOP, as this example shows, you're able to pull together crosscutting behavior into one object and apply it easily and simply, without polluting and bloating your code with features that ultimately don't belong mingled with business logic. Instead, common crosscutting concerns can be maintained and extended in one place.
This is what aspect-oriented programmers deem orthogonal concerns. Profiling is an orthogonal concern. With AOP, you can remove that code.
A modern promise of middleware is transparency, and AOP pardon the pun clearly delivers. Just as important, orthogonal behavior could be bolted on after development. In Listing One, monitoring and profiling must be added at development time.
With AOP, a developer or an administrator can easily add monitoring and metrics as needed without touching the code. This is a very subtle but significant part of AOP, as this separation obliviousness, some may say allows aspects to be layered on top of or below the code that they cut across. A layered design allows features to be added or removed at will. For instance, perhaps you snap on metrics only when you're doing some benchmarks, but remove it for production.
With AOP, this can be done without editing, recompiling, or repackaging the code. JBoss Cache is a tree-structured, clustered, transactional cache. JBoss Cache can also be used as a standalone transactional and clustered caching library or even an object oriented data store.
It is also very commonly used directly by standalone Java applications that do not run from within an application server, to maintain clustered state. Pojo Cache offers additional functionality such as:.
Pojo Cache has a complete and separate set of documentation, including a user guide, FAQ and tutorial and as such, Pojo Cache is not discussed further in this book. JBoss Cache offers a simple and straightforward API, where data simple Java objects can be placed in the cache and, based on configuration options selected, this data may be one or all of:.
A cache is organised as a tree, with a single root. The only requirement placed on objects that are cached is that they implement java. Note that this requirement does not exist for Pojo Cache. JBoss Cache can be either local or replicated. Local trees exist only inside the JVM in which they are created, whereas replicated trees propagate any changes to some or all other trees in the same cluster. A cluster may span different hosts on a network or just different JVMs on a single host.

Some third-party applications add libraries to the system directory in Windows. These take precedence over Tomcat libraries when looked-up. This means that if those third-party libraries have the same name as the those used by Tomcat native libraries, they are loaded instead of the libraries distributed with JBoss Web Server. In this situation, Tomcat may not start, and does not log any error messages in the Windows Event Log, or Tomcat log files.
