I'm not sure that the manager application is active on our install. The load balancer doesn't mention it, and I haven't seen it in the Apache/AJP config either. I think that in order for it to be enabled and NOT be a potential security risk, access to it would need to be strictly controlled. I tried accessing /manager paths in various ways (even direct to tomcat, bypassing haproxy and apache) and none of those requests worked. I didn't find any immediate evidence that it's enabled under another context path either. But I am the first to admit that I am not very familiar with configuring Tomcat! > You may also run into ClassLoader problems where BasicDataSource (as > loaded by your ClassLoader) != BasicDataSource (as instantiated by > Tomcat). Are these problems mitigated by my usage of the fully qualified class name in the object declaration and the cast? That part of the code actually came from one of our developers ... I probably would have imported the class and used the bare class name. Maybe I should use getCanonicalName instead of getName on the DataSource object. When I can finally run the code for the first time, I'll have a better idea of whether I need to make any changes. > Have a look.

I will do my own searching later, but do you happen to know of some good documentation that covers the basics of implementing ExecutorService? > ServletContextListener is the way to go.

You may have noticed the new reply where I included a paste for new code, using ServletContextListener. It's now *complete* code, instead of a fragment.
