ERROR 500 with Servlet Please help SOON!

Without warning a servlet that was working fine is producing this error. On
my development machine it works fine(Tomcat 3.1 and VisualAge on Win 2000).
When I put my file to the Solaris development environment (Tomcat 3.1,
jdk1.2.2, Apache, Solaris) the following error appears.  Any ideas?
Error: 500
Location: /****/servlet/DBFormInfo
Internal Servlet Error:

Posted by Ryan Schutt <rs...@vt.edu>.
From, the jdk documentation:

java.lang.VerifyError

Thrown when the "verifier" detects that a class file, though well formed,
contains some sort of internal inconsistency or security problem.

I would try recompiling the servlet under solaris..
