Applying interceptors to "old" code

[thestrup]

I've just been assigned to a project that is using EJB2.1. The existing beans are created by XDoclet and I want to apply Interceptors to them.

My question is: Is that possible? Or do the beans have to be created by using annotations (e.g. @Stateless) ? If that is the case, what is the technical explanation?

Is it possible to change the ejb-jar.xml, in such a way that EJB2.1 and EJB3.0 syntax can be used in the same bean?

It is possibly by creating your own container-configurations in jboss.xml (see standardjboss.xml for examples) and implementing the org.jboss.ejb.Interceptor interface (http://docs.jboss.org/jbossas/jboss4guide/r5/html/ch5.chapter.html#d0e12136).

For your second question: it is possible to rewrite the beans for use as 2.1 beans. See http://docs.jboss.org/ejb3/app-server/tutorial/ejb21_client_adaptors/ejb21_client_adaptors.html for details.
