To make things clear, lets do the following: - Post the exact contents of your ejb-jar.xml and jboss.xml - Post the exact code that you are using to lookup the bean(the reason i mention this is, i see that you are using the constant COMP_NAME during lookup whose value is different from what i had asked you to use in my previous post) - Then post the entire exception stack trace that you are seeing. jar -tf rpc.jar This will display the contents of your jar file. Right now, without all these information, i can only *guess* that the object returned from the lookup is an instance of remote home of the Promotion bean and not a local home instance(just a wild guess) resulting in a ClassCastException. Posting the above mentioned files will help in identifying the issue. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3962179#...
