I have added the Hibernate capability.

When I click the hibernate.cfg.xml,
the center panel “Hiberbate 3 configuration” displays two radio buttons: JDBC Driver and JNDI datasource. Hibernate implements its own connection pooling C3P0.

What should I do if I want to have connection pooling?

Is it by default, after adding Hibernate capability, the framework will
have connection pooling? What steps I should do next?

Thanks

I believe the connection pool is transparent, you should setup your properties to connect with a JDBC driver, and then you need to add configuration for your connection pool to the hibernate config fille as well as a cp30 properties file, please see this post to get an idea of how it works: http://forums.hibernate.org/viewtopic.php?t=939066&highlight=cp30&sid=da3561523be923059175771c0169880e

I have read the link.
Do I have to remove the JNDI/DBCP entries in web.xml and server.xml
so to let the hibernate all the things of connection pooling?

You don’t *have* to remove them, just don’t use them. Although if Tomcat automatically makes connectiosn to your DB, you might runout of available connections, so maybe commenting them out temporarily isn’t a bad idea.
