Hello Julia, I am not sure about JBoss 4.0.1 version as we are using JBos 4.2. But, here is a link you can have a look to find more details about where you can change RMIConnectionFactory settings. http://docs.jboss.org/jbossas/jboss4guide/r2/html/ch6.chapt.html You may need to comment the ConnectionFactory settings in deploy/jms/rmi-il-service.xml and enable the same in deploy/jms/jvm-il-service.xml. Hope this would be useful. Cheers, Nirav. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3967161#...
