Hibernate C3P0 connection pool provider

[Kumar Jaya]

Hello,

I have a basic question in hibernate and c3p0. Should I need c3p0.jar in my lib directory for hibernate to use c3p0 connection pool provider. I have configured the hibernate c3p0 properties in cfg.xml file and I did not have c3p0 jar in the lib directory and hibernate did not give any warning messages, but my web application is able to run, so what pool is it actually using?

Thanks
