Version 9

    This document outlines the EJB 3.x support that's currently available in JBoss AS 7.0.0.Beta2


    h3. Support for EJB 3.x session beans


    h4. Annotation based support


    h5. @Stateless, @Stateful, @Singleton :


    JBoss AS 7.0.0.Beta2 has support for annotation based session beans (i.e. @Stateless, @Stateful and @Singleton). A bean annotated with any of these session bean annotation will be picked up and processed appropriately.


    h5. Local annotated views:

         * @Local and @LocalBean : JBoss AS 7.0.0.Beta2 supports local business interface view and the no-interface view of session beans.

         * @Remote view: Currently, the @Remote annotation is processed and a view is created out of it. However, remote view semantics don't apply and it works the same as a @Local.

         * @RemoteHome and @LocalHome view: Furthermore, there is *no* support yet for EJB2.x views (via @LocalHome and @RemoteHome)


    h5. Transaction management annotations:

         * @TransactionManagement : JBoss AS 7.0.0.Beta2 supports both container managed transactions and bean managed transactions, configured through annotations.

         * @TransactionAttribute : Various different transaction attributes (configured via @TransactionAttribute annotation) are also supported. Note that JBoss specific way of setting a transaction timeout through an annotation is *not* yet supported in this version.


    h5. Concurrency management annotations:

         * @ConcurrencnyManagement : Both bean and container managed concurrency support for @Singleton beans is available in JBoss AS 7.0.0.Beta2.

         * @Lock : Both READ and WRITE lock support is also available in JBoss AS 7.0.0.Beta2

         * @AccessTimeout : Support for configuring an access timeout through the @AccessTimeout annotation is also available in JBoss AS 7.0.0.Beta2.


    h5. Init on Startup for singleton beans:

         * @Startup : Init-on-startup support for singleton beans, through the use of @Startup is available in JBoss AS 7.0.0.Beta2


    h5. Dependencies configuration for singleton beans:

         * @DependsOn : Only a partial support is available for this annotation in JBoss AS 7.0.0.Beta2. The annotation is processed and appropriate dependencies are added between the singleton beans. This works fine against @Startup @Singleton beans. But for normal (lazy) @Singleton beans, the @DependsOn may not work as mandated by the spec. This will be fixed in later versions of JBoss AS 7.0.0.Beta2


    h5. Resource injection and EJB injection:

         * @Resource and @EJB : These annotations are supported in JBoss AS 7.0.0.Beta2. These can be used in container managed components to inject the resources and EJBs respectively.


    h4. ejb-jar.xml deployment descriptor based support


    * Support for session beans: JBoss AS 7.0.0.Beta2 allows you to configure your session beans through the use of ejb-jar.xml. All types of session beans (Stateless, Stateful and Singleton) are supported.


    * Transaction Management support: You can configure transaction management semantic through the use of ejb-jar.xml for your session beans. Both bean managed transactions and container managed transactions are supported.


    * Support for business views: Currently only business-local and local-bean views are supported through ejb-jar.xml for session beans. business-remote element is processed and a view is created out of it, but remote semantics haven't been implemented and it works like a business-local for now.


    * Support for interceptors: JBoss AS 7.0.0.Beta2 has support for interceptors of EJBs configured via ejb-jar.xml. However, explicit interceptor-ordering isn't yet supported.


    h4. Merged view of annotations and ejb-jar.xml for EJBs


    Although there is an initial implementation available in JBoss AS 7.0.0.Beta2 for supporting partial deployment descriptor + partial annotation based EJBs, it's still in its early stages and isn't stable. Upcoming releases will have better support for a merged view of EJBs.


    h3. Support for EJB 3.x Message Driven Beans


    JBoss AS 7.0.0.Beta2 has limited support for MDBs. See


    For the moment a resource adapter can be connected to the MDB via the org.jboss.ejb3.annotation.ResourceAdapter annotation.

    This may change in the future.


    h3. Where to ask questions or report issues:


    If you run into any issue while trying out any EJB3 application against JBoss AS 7, then please either report it in the user forums or subscribe to the AS7 mailing list and mail your question there.
