David DeWolf commented on PLUTO-342:
------------------------------------
This is most likely due to issues related to deriving the contextPath
(applicationId). This issue has since been resolved via PLUTO-336 and is
available in Pluto-1.1.2. Please try that and let us know if it didn't work.
I've tested in tomcat and weblogic, but not necessarily websphere. If there's
a different approach we need for webshere, just reopen the issue.
