error using application under Tomcat 4.0

Hi,

I have problems running an application which works well under Tomcat 3.2 .
I get the following error:

It seems to be an error in a stage below our application. Any hints what to
do?

Thanks you!

Re: error using application under Tomcat 4.0

Posted by "Craig R. McClanahan" <cr...@apache.org>.
The problem is happening at line 63 of the generated servlet for your
"errorpage.jsp" page.  It would be useful to look at that file (under the
"work" directory) to see what is really going on.
