Yes, it is :). Just one more thing: There are annotations that can be used in abstract superclasses (like @PersistenceContext, @In, @Out, @Logger, @Begin, @End, @Remove, @Destroy...) and there are some that must be applied to the concrete subclasses (@Stateful, @Stateless, @Name (of course *g*), @Conversational, @Scope, ...). I'm not 100% sure, but I think that you can annotate the methods and properties of a superclass but not the class itself. But as I said, I'm not absolutely sure about that. Maybe someone with a deeper insight into the things going on can tell as a simple rule regarding this ;). View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3961210#...
