I have an ear and a war, with some classes contained in both of them. The servlet
contexts in both applications are named differently. It now happens that, when the war
is deployed and I try to hot-redeploy the ear, subsequent access to a jsp results in a
ClassCastException at the line representing the useBean-Tag.
VG = (com.mycompany.VGActionForm) pageContext.getAttribute("VG",
PageContext.SESSION_SCOPE);
When I move the war away and hot-redeploy the ear (e.g. with unix' 'touch' command),
this Exception does not occur, the jsp gets processed correctly.
The problem also does not occur when I restart JBoss having both apps in the
deploy-dir.
As I have the understanding that the ear and the war get different classloaders, I
have no idea how one should be able to affect the other. Further, there is no warning
or error during the hot re-deployment that would point out any conflicts.
Any hints about where to look or further analyse the problem would be appreciated.
Regards, Hans
