Hibernate > 3.3 and c3p0

As c3p0 does not seem to be bundled with Hibernate anymore (as of versions > 3.3, I am using Hibernate 3.6.0), I'd like to know how to integrate c3p0 with Hibernate.

Obviously the old approach with

<property name="connection.prov开发者_运维知识库ider_class">org.hibernate.connection.C3P0ConnectionProvider</property>

does not seem to work anymore, as the class C3P0ConnectionProvider is not provided by Hibernate anymore. Do I now have to build this on my own or is it safe to integrate the hibernate-c3p0-3.3.x.jar?

Note: I am using bare Hibernate, no Spring etc.

I use the following in hibernate.cfg.xml:

<!-- c3p0 config http://www.hibernate.org/214.html -->
<property name="connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>        
<property name="hibernate.c3p0.acquire_increment">1</property>
<property name="hibernate.c3p0.idle_test_period">60</property>
<property name="hibernate.c3p0.min_size">1</property>
<property name="hibernate.c3p0.max_size">2</property>
<property name="hibernate.c3p0.max_statements">50</property>
<property name="hibernate.c3p0.timeout">0</property>
<property name="hibernate.c3p0.acquireRetryAttempts">1</property>
<property name="hibernate.c3p0.acquireRetryDelay">250</property>

I use the latest hibernate (currently 3.6.0 GA) and I've included in the classpath c3p0-0.9.1.2.jar (currently latest). Everything works as expected.

perhaps you need hibernate-c3po-3..jar
