Hello everyone, First of all, thanks for your attention. I found what was causing the problem. After I post the server log here, I realize that it was loading twice the same component (TestComponent). My business library was being deployed to two different places: the lib folder of the ear archive and the lib folder of the web-inf folder of the war archive. When I deployed it to only one location the problem was solved. Thanks again. Best regards, Rodrigo. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4096192#...
