Hi

I was wondering about the best way of using hibernate with jpa inside a axis2 webservice deployed in tomcat.

Now I've got a c3p0 pooled connection configured in my persistence.xml, like this
<property name="hibernate.c3p0.min_size"
value="0"/>
<property name="hibernate.c3p0.max_size"
value="15"/>
<property name="hibernate.c3p0.timeout"
value="300"/>
<property name="hibernate.c3p0.max_statements"
value="0"/>
<property name="hibernate.c3p0.idle_test_period"
value="3000"/>


but was wondering if I should use a datasource from tomcat jndi instead. A typically query in a method in the web service lookes like this


EntityManagerFactory emf = Persistence
.createEntityManagerFactory("Provenance");
EntityManager em = emf.createEntityManager();
em.getTransaction().begin();

dao.save(object);
em.getTransaction().commit();

em.close();

Any tips on this.
