Subject Question re Hibernate connection pooling with C3P0 and CMT transaction management
Date Sat, 14 Apr 2007 00:11:06 GMT

We are using Hibernate inside session EJBs that use container-managed

Our Hibernate configuration looks like this:

<property name="hibernate.transaction.manager_lookup_class"></property>

<property name="connection.datasource">java:comp/env/jdbc/SessionEJBDataSource</property>

<property name="hibernate.transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</property>
<property name="hibernate.TransactionStrategy">org.hibernate.transaction.CMTTransactionFactory</property>
<property name="hibernate.current_session_context_class">jta</property>

I wonder whether it's possible, or necessary, to use connection
pooling via C3P0
with such a configuration.

I configured the hibernate.c3p0 properties with basic settings and deployed the
application. It was slower to start, but then seemed to run much faster.

But is it the right thing to do?
