I'm having a problem with enabling c3po connection pooling with hibernate. I'm using hibernate 3.2.1.sp1 and c3po-0.9.1.jar. My context is a junit 3.8.1 test suite running inside of MyEclipse 5.1 w/ jdk 1.5. My db is oracle 8.1.
My junit test works fine.
I attempt to specify a simple c3po connection pool inside my hibernate.cfg.xml file. If I add that, I get the following exception:

I have no idea why I'm getting an exception on a jboss/jmx PropertyAccess class not found. I'm not using boss at all. I tried to add the jboss-jmx.jar file to my classpath, but that did not fix the problem either.
