Hi, I'm using JBoss 5, i tried to configure Data Sourse (name= VIRTUAL) in conf.cfg.xml Hibernate file with thi istructions:

<property name="hibernate.connection.datasource">java:/VIRTUAL</property>
<property name="hibernate.transaction.factory_class">net.sf.hibernate.transaction.JTATransactionFactory</property>
<property name="hibernate.transaction.manager_lookup_class ">net.sf.hibernate.transaction.JBossTransactionManagerLookup</property>

when I try to save a Object I got this error:

java.lang.ClassNotFoundException: net.sf.hibernate.transaction.JTATransactionFactory

where I can find this class?

Many regards, Andrea.

I was using wrong classes, hibernate 2 instead hinernate 3.
