FORM based login Error forwarding to login page

           Summary: FORM based login Error forwarding to login page
           Product: Tomcat 5
           Version: 5.0.25
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Unknown
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: dwilson@relevant.com


I am having trouble with FORM based login using JDBC Realm. I have posted my
question twice on the Tomcat users list and even sent an email to the tomcat
webmaster with no responses from either methods.

So this is the problem...
When I go to a restricted resource the user will get a blank page. Tomcat
console gives this error:

However, after that error if the user manually goes to the login page,
http://localhost:8080/E3/login.faces, then they will get the login page and
after logging in they will get redirected to the original page that they tried
to goto.

Please see the attached config files..

Thank you,
