Custom error messages for <form-error-page>

[mmarconi]

I've spent hours trying to find a solution to what I imagined was a common problem:

I have a custom JAAS login module that relies on a database connection. It is possible that this connection is broken when users attempt to authenticate themselves.

This leads to a forward to the page specified by the <form-error-page> tag. Now, how do I distinguish between a database failure and incorrect authentication data?

I can't simply tell the user their sign in failed. I must let them know if we are experiencing databse issues or their username/password combo is incorrect!

Any way to get at those exceptions from the error JSP?

A thousand blessings to anyone with an answer...

This requires a custom interaction between either the login module or the tomcat valve to propagate the login failure reason to the app code. There is no standard fow HOW authentication is integrated into the web container, and therefore its a boolean pass/fail event as far as the standard apis go.

Thanks. That sounds like a lot of work for little gain. I guess the database is reliable.
