[jboss-user] [JBoss Portal] - Unable to access the Portal Pages

[abhilashk_cse]

I tried to configure the Themes using admin page on Jboss-portal-2.6.0-DR1 release. But i was unable to change the theme for the entire portal by clicking the root. After that, while i was trying to navigate the other pages, it is gving an exception. I restarted the server, the main or default page is coming, when i try to access other pages, it is again giving the exception:
