Configuring Hibernate Connection pooling with c3p0 on Oracle10g

I am unable to get a connection pool using c3p0 with Hibernate and Oracle. The database is Oracle 10.2, and hibernate version is 3.6.5. When I take out the c3p0 settings from the config, it works fine.

I've tried to limit the number of connections requested and statements processed and still no luck.

Here is my config.xml and stack trace:
