Currently the application running on jboss4.3.Application uses cas server 3.0 for authentication and everything is working fine.
Now we are migrating application from jboss4 to 6.When Application logins it goes to cas server.
after authentication.it returns back & shows following error-
javax.servlet.ServletException: JBWEB000247: Filter execution threw an exception
