Hello all,
I've got a web application on Tomcat which works fine using Sun ONE Studio 4
CE's Tomcat server, but fails on Tomcat 4.0.6 on my OpenBSD server. The
example Tomcat servlets work, but JDBC doesn't (and this application talks
to a back-end MS SQL Server 2000 for most things, including authentication).
It uses the mssqlserver.jar for JDBC, which looks like the standard MS SQL
JDBC driver (unzipping the jar gives a bunch of class files).
How do I proceed to fix this? I unfortunately have a deadline of Friday.
I can provide the class files if needed, but they show thrown exceptions
when JDBC is invoked, and they do work on Forte's Tomcat server.

Thoughts? Pointers on troubleshooting JDBC?
Thanks!
