I think My problem is a bit different, as I have an ejb jar A contains the session bean and ejb jar B contains the entity that will be removed through the session bean. I have verified that the EntityEnterpriseContext of ejbjar B have an object in it that has a Classloader of ejbjar A. I am still looking how it can happen since my understanding of EntityInstanceInterceptor is that access to EntityEntrepriseContext "object" can only be done through the EntityCache which is attached to the entity so to the ejbjar B classloader. I have also verified that access to EntityEnterpriseContext may be done without going to EntityInstanceInterceptor. Before removing your entity, can you try to run any getter method on the remote interface. just before calling remove(), it should solve your problem. >Thanks wt. > Vincent. _ Do You Yahoo!?

Re: [JBoss-user] java.lang.Illegal.Argument Exception : object is not instance of the class
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.

RE: [JBoss-user] java.lang.Illegal.Argument Exception : object is not instance of the class
I am pretty sure there is a problem in the instances pool somewhere, I also receive something similar to that. The trick is tio call any dummy remote method before calling remove. Please help me figure out what happen : Do you play with 2 session beans in 2 different ejb jar here ?
