Chuck,
Thankyou very much. This pointed me in the correct direction. I
didn't notice the 8009 connector. I am running tomcat standalone, and I have
no need for an 8009 connector. When I commented it out, my issue is
resolved.

As Filip pointed out, without a driver you'll go nowhere. This would

What driver jar did you put in the lib dir?
Is there another copy in your WEB-INF/lib? You must remove that one if
there is.

Well, you could run all the Tomcat instances on the same box. What's
that saying about eggs and baskets?
hibernate is using the org.apache.commons.dbcp pool, so you need to
configure that one, or tell hibernate to use tomcat's pool
the clue here is, that tomcat's connection pool (while the same as
commons.dbcp) has the package renamed to org.apache.tomcat.dbcp.

How much RAM have you set to your Tomcat?
Don't confuse physical RAM with the virtual memory sizing of the Java

there are simultaneous requests come for a servlet, it will either queue the
requests and serve one by one or create multiple threads of the servlet and
serve the request.
My question is, what / how tomcat handles
Yup that's what I thought was happening. When all threads are busy,
tomcat can't accept any more requests. To an extent tomcat still
accepts some request and waits for a thread to free up but eventually
it'll reject the requests with a 50x error.
