Ok, sorry. I just discovered from older messages in this forum that standardjboss.xml and jboss.xml are ignored for EJB 3. I also found advices to manipulate ejb3-interceptors-aop.xml or use the @CacheConfig annotation for my EJB. But all I could achieve with that was a passivation not a destruction of the bean. So I still have no idea. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4021540#...
