How can an MBean depend on a SessionBean?
You can specify a dependency between the MBean and the Container that
contains the SessionBean (which is an MBean itself following the JBoss
lifecycle model), for example:
The archive jboss-media-entity-ejb.jar contains a session bean called
MediaEntityManager. When the archive is deployed the following MBean
will be created and will be visible through the jmx-console:
Specifying the dependency is then easy:
... <mbean code="my.mbean.class" name="mydomain:name=myname"> ... <depends>jboss.j2ee:module=jboss-media-entity-ejb.jar,service=EjbModule</depends> </mbean> ...
Your MBean will only be started after the container (and as a result
the contained SessionBean) has been started, so you can lookup its name
in JNDI, call its methods, etc.
Sometimes, it just happens that an archive gets deployed but SessionBeans it contains do not (for various reasons: unresolved dependencies, programmatic error, etc.).
In this case, dependency on jboss.j2ee:module=jboss-media-entity-ejb.jar,service=EjbModule won't do any good.
If a SessionBean to depend upon, however, has a remote interface, adding a dependency on jboss.j2ee:jndiName=<remote interface JNDI name>,service=EJB seems a better alternative.
