I am trying to setup SSO using WebSeal with Weblogic. Pega version 7.4. I have modified web.xml file with servlet and url pattern detail. However, if I browse to servlet path (http://..../prweb/websealservlet), I get 304 error. It seems like it is not allowing me to go to the SSO servlet at all. Same problem if I try to connect to Pega directly, or using a load balancer.
