Yes, it's my code. The null pointer is the connection I'm trying to make to the database (Connection con). The first two lines are telling me that don't have a connection to the database; using code that works perfectly on the development machine. I've even previously, on the dev machine, successfully adjusted this code to connect to other databases in the LAN. On the problem machine, I've even involved a db administrator in trying various ways of specifying the db in the connection call that isn't working there.
What I'm hoping at this point is that there's more useful info in the error message. Like, does something in the neighborhood of
say anything new? I vaguely remember looking at something to do with Valves in one of the
Tomcat configuration files while setting up the development machine. This is new to me though. If I did something like that, it would have seemed quite obscure and I was just following a set of instructions. Haven't done anything like that on the problem machine ... although I've tried to compare files in Tomcat's config folder to be sure they're the same.
