Make sure you're using the latest version of poolman, or even the CVS version. The JMX management it uses has very screwy (basically, non-functional outside of tomcat's broken classloader) classloading. Also try and run it in non-JMX mode. The latest version does not require xerces and works with JAXP as far as I know (I submitted a patch for that).
On the other hand, if you're using Orion, why not use Orion's connection pooling and save yourself from all this pain?
