Hi Guys,

I'm trying to use the following setup:

Tomcat 6.0.16
c3p0-0.9.1
Hibernate-c3p0-3.3.1.ga, Hibernate-core-3.3.1.ga, etc

Everything starts fine until this occurs...

The c3p0 jar is in WEB-INF/lib and I can see the class (BasicResourcePool$1DestroyResourceTask) when I open the jar. Is there anything else I'm missing here?

Thank you, Q
