Hibernate 4 -- configuring C3P0
===

I would not have posted this unless I was truely frustrated. I am trying to configure C3P0 with Hibernate 4.1.1 in a very simple application but I am getting a class not found exception. I have included C3P0 specific jar file in my classpath. hibernate-c3p0-3.5.2-Final.jar

hibernate.properties:

    hibernate.connection.provider_class=org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider
    hibernate.c3p0.acquire_increment=1
    hibernate.c3p0.idle_test_period=180
    hibernate.c3p0.max_size=60
    hibernate.c3p0.max_statements=0
    hibernate.c3p0.min_size=10
