[jboss-user] [JBoss Portal] - Help!!! HTTP Status 500 Error

[linamariep]

Hi.  Please help me resolve the error below.  We created a JBoss Portal that was working fine when i started tinkering with the layouts and themes.  I initially encountered this error with a lay null pointer error which i was able to resolve (through revising the default objec.xml)....however,  the problem below still persists.  Any assistance would be greatly appreciated.  I am very new to JBoss portal.  Wahhh!!!!
