为JMS队列创建定制属性

Question

I am using Jboss.x , EJB3.0.

I have two JMS queues. "A" queue and "Error" Que.

A que has a retry mechanism, so after 3 retries, the MSG will be deliver to an error queue automatically, and there mdb will listen.

I want to add to the MSG which will be delivered to the error Que, an extra property which I will define. (Ofcourse I cant add to the body an extra line, since I have rollbacks, and each time a rollback is being executed, the body will rollback also)

So I read little in the net, and I got that I can use the header for this purpose(roll backs wont affect it). in order to user the header for my custom property I must create JMSPropertyType and add to it the header. I didn't find info how to do it, mybe anyone could show me, or maybe there is another way of doing this?

thanks, ray.

Answer 1

Transactional retry limits and poison message queues (your error queue) are vendor-specific features. They're not in the JMS spec. You should read your vendor documentation (JBOSS, apparently) for any details.

I'm skeptical that a failing receiver could add a property to a message as you ask. Your vendor might implicitly add some properties itself. I think I've seen a case (BEA JMS?) where they add some vendor-specific property with the failed delivery attempt count.
