Re: Problem upgrading to mysql-connector-java-5.0.8

[Todd Farmer]

Hello Randy,

I don't see anything in the provided stack trace that indicates the problems is MySQL-related. You'll probably need to check your JSP compiled code to figure out what null object may be. If it's a Connection object, you'll need to look for any earlier indications in your log that creation of the Connection or DataSource failed. At most, this message is telling us that you're trying to use something which doesn't exist. We don't yet know what that is, or why it doesn't exist. Hopefully your logs provide that information in some other context.

I'll note that when you're "upgrading" to a version of a product that's over 5 years old, you might want to consider looking at something a bit more current. :)

This holds true for your MySQL Server (and JRE) as well. It's going to be pretty hard to reconcile the behavior of a Java app running in an ancient JRE against an ancient MySQL Server using an ancient JDBC driver - even if the stack trace was useful.
