[rules-users] Is transaction management required for Drools process / session persistence

Hi, I am trying to do Drools persistence in Tomcat with Hibernate, but it would seem it also requires transaction management. Is that true? In the meantime I tried to setup Bittronix to provide the transaction management, but I can't get Hibernate to find the datasource at all. I ve followed the BTM integration instructions for Tomcat, I ve also done followed the BTM integration instructions for Hibernate, but still nothing, Hibernate keeps saying it can't find the datasource. Can anyone shed some light on this ? BTW: my database is SQL Server Thanks
