No JTA transaction found - Transacational inserts and updates not working

[davestar]

I have a Spring 3.0.5 application deployed in JBoss 5.1 with JPA entities using

javax.persistence.EntityManager for database operations like entityManager.find(id), entityManager.persist(object), entityManager.merge(object)

All my get() and getAll() operations are working fine but any persist or merge operations are not working neither am I seeing any exceptions or errors thrown in the JBoss logs.  When I enable debug on the server I see the below two lines being repeated everytime a database operation is performed.

17:10:01,505 DEBUG [AbstractEntityManagerImpl] Looking for a JTA transaction to join
17:10:01,520 DEBUG [AbstractEntityManagerImpl] No JTA transaction found

Can you please help me identify the cause of this message? or why transactions are not working?  Thanks for the help.

My persistence.xml

   <persistence-unit name="ties-2" transaction-type="JTA">
      <provider>org.hibernate.ejb.HibernatePersistence</provider>
      <jta-data-source>java:/ties-2Datasource</jta-data-source>
      <!-- The <jar-file> element is necessary if you put the persistence.xml in the WAR and the classes in the JAR -->
      <properties>
         <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect"/>
<!--         <property name="hibernate.hbm2ddl.auto" value="validate"/>-->
<!--   <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>-->
         <property name="hibernate.show_sql" value="true"/>
         <property name="hibernate.format_sql" value="true"/>
         <property name="jboss.entity.manager.factory.jndi.name" value="java:/ties-2EntityManagerFactory"/>
           
      </properties>
   </persistence-unit>


My spring jpa config

<beans>
<!-- JPAAccountDAO has JPA annotations to access EntityManager -->
    <context:annotation-config/> 
 <jee:jndi-lookup id="entityManagerFactory" jndi-name="java:/ties-2EntityManagerFactory">
 </jee:jndi-lookup> 
 <bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
          <property name="transactionManagerName" value="java:/TransactionManager"/>
        <property name="userTransactionName" value="UserTransaction"/>
    </bean>
 <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
 <!-- Database LOB Handling -->
 <bean id="defaultLobHandler" class="org.springframework.jdbc.support.lob.DefaultLobHandler" />
 <!-- Read in DAOs from the JPA package -->
 <context:component-scan base-package="com.rtd.ties2.dao" />  
</beans>

I'm not familar with Spring the EJB container will do the Tx work for me.

But how a transaction is started if you use persistence. Sounds to me that the get will work without but the update need it.

Do you wanna make Spring the transactions for you or EJB.

If you do it with EJB than I recommend to create a local session bean where you get the entity manager (make the session bean transaction.required).

Get the session bean in spring via jndi lookup and inject the entity manager to your base dao class.

This is a way to use EJB transactions (not the most elegant, but working)
