I am trying to get XA transactions working in a Spring v3 application inside WebSphere v7.
My App Context reads:
<bean id="jmsConnectionFactory"
class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jms/MQConnectionFactory"/>
<property name="resourceRef" value="true"/>
</bean>
<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
<property name="connectionFactory" ref="jmsConnectionFactory"/>
</bean>
<jee:jndi-lookup id="myDB" jndi-name="jdbc/myDB"/>
<bean id="txManager"
class="org.springframework.transaction.jta.WebSphereUowTransactionManager" />
<tx:annotation-driven transaction-manager="txManager"/>
I m referencing this article that says mix in the UOW txn manager and you ll be fine. But it doesn t work that way. Instead, in the following code, the message is destructively read and is not rolled back when an exception is thrown.
The transactional logic is (in scala):
@Transactional(rollbackFor = Array(classOf[Throwable]))
def processNextMessage(category: String) = {
val maybeMessage = readNextMessage(category) // <- this is a destructive read
for (message <- maybeMessage) {
// this is temporary code for testing
throw new RuntimeException("blaaaaaah")
// end temporary code
// sendToQueue(message, queue)
// writeToMessageStore(message)
}
}
Can anyone advise how I can use WebSphere s JTA transaction manager with Spring?
