Overall, it looks like the Tomcat Server is trying to do a security lookup against the app server and is not able to.

This could be caused by a lot of things:
- The app server isn't available
- The security passwords are not the same between the two tiers
- The DB isn't accessible, or hasn't been setup correctly - which prevents the App server from looking up security info.
- The DB connection pool isn't creating correctly -- specifically the DEDICATED_SECURITY pool.
- General network or communication issues between the tiers.
- Using the wrong version of WebLogic
- Improper file permissions on the WebLogic install, causing the security realm libraries not to get copied into place during the install.
- The list goes on. Unfortunately, this is a pretty generic error

Chris,

Thank you We restarted Services and Application server and issue resolved.. Didn't get the exact reason from our DBA though.
