Spring JMS and Oracle AQ

Question

Has anyone got Spring JMS to work with an Oracle AQ queue?

I am trying to connect to AQ based on this article http://blog.nominet.org.uk/tech/2007/10/04/spring-jms-w

Answer 1

That error indicates to me it's actually working but you're not giving it a payload factory to create the object coming off the queue. You do that when you create the receiver. In this case my payload is XMLTYPE so I just use its payload factory:

queueReceiver = ((AQjmsSession) queueSession).
   createReceiver(queue, XMLType.getORADataFactory());

This is how you can solve it if you are using Spring: http://blog.javaforge.net/post/30858904340/oracle-advanced-queuing-spring-custom-types

In a "springless" environment just create your own message consumer like described in the blog post above.

You have to supply a JDBC type map when you want to en-queue or de-queue AnyDataType or User Defined Payloads.

The best place to do it, in the Link you have posted will be in OracleAqDestinationFactoryBean.getObject.

In my case, I wanted to de-queue Oracle LCRs which are of XMLType , so I had to do the following in the getObject

public Object getObject() throws Exception {
    QueueConnection queueConnection = connectionFactory.createQueueConnection();
    AQjmsSession session = (AQjmsSession) queueConnection.createQueueSession(true,
            Session.SESSION_TRANSACTED);
    Map map = session.getTypeMap();
    map.put("SYS.XMLTYPE", Class.forName("oracle.xdb.XMLTypeFactory"));
    return session.getQueue(queueUser, queueName);
}

Remember for AnyDataType Payload you have to use OCI JDBC driver, as the thin driver won't do.
