Hi All, Inside the persistence.xml file We are using Transaction manager: - TRANSACTION FOR JBOSS <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup" /> - TRANSACTION FOR TOMCAT <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.BTMTransactionManagerLookup"/> This means that for every server or container I have to disable one and enable the other. Is there a way to use the same transaction manager for both application servers?
