Subject RE: DB connection error -Tomcat 6 config

Admittedly, this is my first dance with the Tomcat manager app, deploying anything. I was,
I suppose archaically, arguably, just using the startup and shutdown commands at the cmd prompt
level.

Although when I ran "find memory leaks" or whatever that little button reads, it did mention
my app had some classes that were still being used, which seemed odd, but I assume accurate.

Thanks, pid.

I've also seen this intermittently with the latest mysql connector/J
(.12) but I'm going to start a new thread for this when I can replicate it, because this thread
is too big* and it's a slightly different topic.
