I am using JBoss - 4.0.4 GCA. I followed the following steps after installing the server:
1) I downloaded jboss-EJB-3.0_RC8-FD
2) Copied ejb3-persistence.jar in server/default/lib
3) Copied ejb3-interceptors-aop.xml in server/default/deploy
4) ejb3.deployer in server/default/deploy
Note that with the injection part commented out, everything works fine, the EJB gets
deployed and i am able to invoke methods on the EJB.
I have attached the source code and the .ear file along with this issue for reference.
Just place the MyEJB3.ear file in the %JBOSS_HOME%/server/default/deploy directory, after
following the steps mentioned above, and start the server to reproduce the issue.
