DAO

<bean id="dao1" class="com.example.Dao1" activation="eager">
     <jpa:context unitname="PU" property="entityManager" type="TRANSACTION" />
</bean> 

Service bean

<bean id="service1" class="com.example.Service1" activation="eager">
     <property name="dao1" ref="dao1" />
     <property name="dao2" ref="dao2" />
     <tx:transaction method="*" value="Required" />
</bean>

Service bean method pseudocode

boolean create(entity1, entity2) {
     dao1.persist(entity1);
     dao2.persist(entity2);
} 

When dao2 persist failed, the transaction did not get rolled back. Entity1 is inserted into the DB.

Additional information

1) TransactionManager definition

<reference id="platformTransactionManager" interface="org.springframework.transaction.PlatformTransactionManager" />
<bean id="JTA_TRANSACTION" class="org.apache.camel.spring.spi.SpringTransactionPolicy">
     <property name="transactionManager" ref="platformTransactionManager" />
     <property name="propagationBehaviorName" value="PROPAGATION_REQUIRED" />
</bean>

2) My persistent unit is of type JTA and hibernate as the provider.

3) I have an ExceptionMapper, which when I look into it, the stacktrace shows the transaction indeed is marked for rollback.

4) The service beans are not separated to another bundle.

I am wondering if:

1. CXF OutFaultInterceptor has "eaten" the exception that is supposed to be caught by the container for transaction rollback. As a result, the rollback did not occur.
2. The Entity Manager has to be the same instance shared amongst all DAOs for the rollback to happen.
3. Could it be that I need to separate the service into another bundle?

Appreciate if someone could let me know the correct approach on transaction handling at service layer for cxf jaxrs endpoint.
