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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
