Matt, I was having the same issue, but I fixed it buy adding the following line to the none jta datasource you set up. | <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider" /> | so your booking local source should read. <persistence-unit name="bookingLocal" transaction-type="RESOURCE_LOCAL"> | <properties> | <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/> | <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcDriver"/> | <property name="hibernate.connection.username" value="sa"/> | <property name="hibernate.connection.password" value=""/> | <property name="hibernate.connection.url" value="jdbc:hsqldb:."/> | <property name="hibernate.max_fetch_depth" value="3"/> | <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider" /> | </properties> | </persistence-unit> I went back and tried the original persistence-test.xml file, which I added the above line to, this also fixed the tests. It appears the the bootstrap bean in the jboss-beans.xml dosn't pick this up. my persistence-test.xml now reads. | <persistence-unit name="bookings"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:/bookingsTestDatasource</jta-data-source> | <properties> | <property name="hibernate.hbm2ddl.auto" value="create-drop"/> | <property name="hibernate.show_sql" value="true"/> | <property name="jboss.entity.manager.factory.jndi.name" value="java:/bookingsEntityManagerFactory"/> | <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider" /> | </properties> | </persistence-unit> | Hope that makes some sense.
