Use the JNDIView http://wiki.jboss.org/wiki/DisplayTheJNDITreeWithTheJMXConsole to check what's the jndi name for your bean1 in EAR1. Then try using that as the mapped name for injecting this bean in bean2 in EAR2. You can post the JNDI tree here, if you need help in understanding the output. P.S: A new forum for JBoss AS5 has been created at http://www.jboss.com/index.html?module=bb&op=viewforum&f=287 for JBoss AS5 specific questions. Let's use that forum for any new questions on JBoss 5. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4162996#...
