@petemuir: I thought about that, too. But it's somehow unaesthetic. In this respect I'm like a little child: If there is Dependency Injection I want to have it ;). @thomas: Ooops. That's something I overread in the manual. Since working with EJBs all the time this was the first time I encountered problems with leaving out the Interceptor. So thanks for the hint, the Bean works now :). But a few questions to understand everything better: - All beans need a SeamInterceptor, otherwise Injection doesn't work, right? - With ejb-jar.xml it's possible to put that Interceptor around every EJB automatically without needing to add it to every single EJB explicitly (very nice), correct? - But: Why aren't there any Interceptors in the Hibernate example? I mean the action beans have a LoginInterceptor that calls BijectionInterceptor etc., but what about the entity beans? Plus: I'm still wondering very much why the EJB converter first worked and then not. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3961045#...
