Hi Vincent , I have only 1 session bean and many entity bean in different jar.(session bean facade model). I did not why . I can remove entity bean without any error before. I have tried it in jboss2.2.1 and jboss2.1 and hit the same error message. I did not know why. My guess is that something to do with ClassLoader. Thanks wt.
