Hi Gloria, I use Jboss 4.0.2 and the Red Hat Enterprise Linux ES release 3 (Taroon) and I have the same problem. If the web application run only in Tomcat in Windows, works fine. But in Jboss, the problem occurs in the change of a first to second page, but in the others access it works fine. The bad news is that I'm looking for a solution too. If anyone have a solution or a "light", post it. Thanks a lot, Alexandre View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3958813#...
