--------------------------------------------------------------
This document outlines the EJB 3.x support that's currently available in JBoss AS
7.0.0.Beta2h3. Support for EJB 3.x session beansh4. Annotation based supporth5.
@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, this annotation is
processed and a business view is created out of it. But remote semantics do not yet work
and a @Remote behaves the same as a @Local for now. * @RemoteHome and @LocalHome view:
Furthermore, there is *no* support yet for EJB2.x views (via @LocalHome and
@RemoteHome) h5. Tansaction 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 aren't yet supported. Instead it works as 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 EJBsAlthough 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. 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
