No. I did not realize that would be needed since it seems to work just fine when invoked from session beans. I want to use the same, working infrastructure, but from a worker thread. That being said, this is my persistence.xml: | <persistence-unit name="MyProject"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:/MyProjectDatasource</jta-data-source> | <properties> | <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> | <property name="hibernate.hbm2ddl.auto" value="update"/> | <property name="hibernate.show_sql" value="true"/> | <property name="hibernate.format_sql" value="true"/> | <property name="jboss.entity.manager.factory.jndi.name" value="java:/MyProjectEntityManagerFactory"/> | </properties> | </persistence-unit> | Thanks for your help in the wee hours of the morning! -Raj View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4153206#...
