Sorry for the tons of posts -- an edit post feature would be nice ;-) I have this working on JBoss 4.0.5, the only change I made was the EJB Home name. I changed it from iiop/TestBean (which didn't work) to simply TestBean. Whether this is really using IIOP to invoke the bean, I don't know but the PROVIDER_URL I am using is iiop://localhost:3528 and that seems to be a pretty strong indicator that IIOP is in fact being used. The only problem I have is this line from the JBoss output: 17:43:30,402 INFO [TestBean] Home IOR for TestBean bound to iiop/TestBean in JNP naming service What is bound to iiop/TestBean? When I use iiop/TestBean, the lookup fails. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053290#...
