If you have a NullPointerException somewhere in your tag or jsp pages, this
could happen.  It happened to me a couple of times.  Look for any variable
that might be null.

when I look at the manager html page, it indicates that the application is
running properly. The problem only happens when I have a specific custom
taglib included in the page.
