Exception with JTA/JNDI when moving from Tomcat
I'm moving a war from Tomcat to JBoss, using the Open in View filter, and am having a problem switching to JTA transactions and JNDI lookup of the session factory.
I'm using the caveatemptor HibernateFilter and HibernateUtil classes and the exception gets thrown when the HibernateUtil is building the session factory.
My hibernate.cfg.xml is :
<hibernate-configuration> <session-factory> <property name="show_sql">false</property> <property name="dialect">org.hibernate.dialect.DB2Dialect</property> <property name="hibernate.connection.datasource">java:jdbc/CustomerReportingDB</property> <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property> <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property> <property name="hibernate.session_factory_name">java:hibernate/HibernateFactory</property> <!-- Mapping files --> </session-factory> </hibernate-configuration>
