The remote interface must extend the javax.ejb.EJBObject int

[bluezero000]

I have JBoss [WonderLand] 3.2.5 (build: CVSTag=JBoss_3_2_5 date=200406251954). When I try to deploy an EAR, it fails on a Session Bean. The warnings/errors are:

2005-01-08 21:33:16,210 WARN [org.jboss.ejb.EJBDeployer.verifier] EJB spec violation:

Can someone give me a clue what's going on? Thanks a lot.

It turns out that JBoss IDE generates another class that extends my session bean. In ejb-jar.xml, it specifies my original bean class as remote interface. Is this a bug in JBoss IDE?
