Hi,
I have a server application running in karaf and I have problems to combine
transactions defined in spring/camel and code having @Transactional annotation.
In my blueprint.xml I have defined something like this:
<reference id="jtaTransactionManager"
interface="javax.transaction.TransactionManager" />
<reference id="userTransaction"
interface="javax.transaction.UserTransaction" />
<bean id="transactionManager"
class="org.springframework.transaction.jta.JtaTransactionManager">
<argument ref="jtaTransactionManager" />
<argument ref="userTransaction" />
</bean>
<bean id="PROPAGATION_REQUIRES_NEW"
class="org.apache.camel.spring.spi.SpringTransactionPolicy">
<property name="transactionManager" ref="transactionManager" />
<property name="propagationBehaviorName"
value="PROPAGATION_REQUIRES_NEW" />
</bean>
So I start a new transaction by using PROPAGATION_REQUIRES_NEW in a camel
route. The camel route leads to a WebService endpoint. Anywhere in the
underlying code where I use @Transactional and get a EntityManager injected I
can see that the transaction is handled by a coordination from aries-jpa and
gets committed by the uppermost @Transactional annotation.
But I want that the underlying code uses the transaction created by the
PROPAGATION_REQUIRES_NEW in the camel route so I am maybe able to rollback the
transaction inside the camel route. How to achieve this? Do I have to use a
TransactionManager from aries-jpa instead?
Thanks in advance,
Christian
