Hi Peter, First of all, thanks for your reply, and second, I admit my fault with JBoss EAS typo, I thought it was called the same way as free JBoss AS + "Enterprise" ;-). Therefore, talking about JBoss EAP, we're not currently using any messaging or any other "special" service from AS, then I will assume that an application currently running under JBoss AS 4.2.3 should properly work under JBoss EAP 4.2. Thanks very much. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4204889#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
