Thanks for helping me to get oriented. The following was particularly helpful.

So, now I'm guessing ok ... they use some commons-dbcp components, but it's still different. Anyway, you might be able to see why I came and asked for some orientation help. My first impression was that Tomcat's current pooling mechanism is completely different and I just couldn't find the right documentation for it.
