Copy-paste error. I made two new interfaces, and after the copy-paste, I haven't changed the names in the annotations of the *Bean.java files: @Stateless(name="PersonManagerService") I don't know why I looked over these, but unfortunately these are strings, so the type system couldn't detect this error. Another conclusion: the consol output provided less verbose output than the server.log, so I should look at that thoroughly next time. I spotted that a class name mentioned two times in the server.log during the EJB deployment, shortly after my quoted log section. That's how I found the error. I was looking at server.log before, but not thoroughly enough. Thank you for your help! -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/561392#561392] Start a new discussion in EJB 3.0 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
