Saptarshi,
You're right - it definitely appears to be a password miss-match issue with the GUEST.ADMIN user account. WebLogic startup is clean and the problem doesn't appear to occur until Tomcat is started up.
Can you verify that your GUEST.ADMIN password is the same as below?
Code:
SQL> select gl_password from gl_user where gl_user_gid like 'GUEST.ADMIN';
GL_PASSWORD

If it is, then you shouldn't need to set the
-DGuestEncodedPassword setting in the tomcat.conf file.
Also - could you verify what patch level you're at. The latest is CU03 RU02. I'm not aware of any bugs related to this after CU02, but it's always worth a try.
Thanks!
