A bit more details about the structure of your ear might helpful
Ok, my ear have the next structure:
My problem is that the first war try to access to one directory that it's in the jar1.jar (org\jasig\cas\web), and it doesn't find it. The jar has the structure that the ear needs.
If you need more information, I give you. One detail, I deployed ok this ear on JBOSS 4.2.3.
