Yes you do need transaction management. How is your datasource configured in hibernate? Are you using jndi? This may help: http://docs.codehaus.org/display/BTM/Jndi13 The bit you want is this: You just have to create a jndi.properties file in your classpath with this content: java.naming.factory.initial=bitronix.tm.jndi.BitronixInitialContextFactory -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Gustavo Tenrreiro Sent: 27 August 2010 15:36 To: rules-users(a)lists.jboss.org Subject: [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 _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ************************************************************************************** This message is confidential and intended only for the addressee.
