[Wtp-wst-dev] Error when deploying to JBoss within Eclipse 3.2 IDE

["Savoy, Melinda" <MelindaSavoy@xxxxxxxxxxxxxxx>]

Our dev team just installed Eclipse 3.2 and JBoss 4.0 on our local
Window XP machines.

It appears that the issue is that Eclipse will rebuild and redeploy the
EAR to JBoss while at the same time opening up IE and trying to load the
JSP. JBoss eventually will see the new EAR and it has to go through a
process of unloading the current EAR from memory and then reloading the
new EAR. The error you see is happening when JBoss unloads the current
EAR from memory as far as I can tell.  

Any HELP or DIRECTION would be greatly appreciated.

When trying to run a JSP page from within the Eclipse 3.2 IDE I am
getting the following error:

HTTP Status 500 -
