Subject RE: Error with JDBC connecting from servlet
Date Sat, 15 Jul 2000 20:28:26 GMT
If you're getting a stack trace, that could be pretty helpful in diagnosing
the problem.

All I can think of is assure that you don't have an old version of the JDBC
drivers in your WEB-APP/lib directory, or at some place in your Tomcat
CLASSPATH.
