Are you sure it's a filter and not a listener?

If you can't get any information in the log files, try removing
everything from your web.xml and then re-adding each listener
individually. At least that will narrow down which listener is failing.

You could also wrap all your listener init code in try/catch blocks and
log any errors yourself.

You could also modify logging.properties and crank-up the logging level
(though SEVERE seems like something that should already be logged... and
it IS being logged: just not with a stack trace).

What version of Tomcat are you using?
