Timeout for JMS Receiver.

Hi,

I want to write code for following requirement:

1. I want to send a request message on one queue say Q1.
2. I should keep checking for response to the earlier request on another topic say T1, for next 2 mins.
3. If I dont receive a response on T1 within 2 mins I stop waiting for the response and continue.

There can be more than one instances which will put a message on Q1 and connect to T1 to wait for the response.

Now the real problem that I am facing is where do I write the code for counting two min timeout?

Any suggestions?

Thanks,
Pankaj

Hi pankaj,

You can listen for the response from the topic T1 in the onMessage method. You can use a Timer by implementing the TimedObject interface and can wait for a timeout of 2 mins in the same method.

If i don't get a response that is to say my onMessage doesn't gets called in 2 mins...my timer expires and i don't need to wait.

Hope this helps.

Thanks,

Hi Sandip,

Thanks for the quick reply. I noticed that TimedObject is not supported by Weblogic 8.1 sp5 (supported from weblogic 9.0 onwards). Please correct me if I am wrong about this. So I will not be able to use TimedObject.

If there is any other way to implement this?

Thanks,
Pankaj.

Hi Pankaj,

The classes for EJB Timer Bean(TimedObject.class) are missing in their J2EE-Jar for Weblogic 8.1.

You can try by putting the TimedObject jar file in application classpath. But i am not sure if this works.

Thanks,

Hi Sandip,

I am doing this change for one of the clients and I cant assume that they will have this jar file

Thanks,

Any inputs?

I have implemented this Using NotificationListener interface. But there is one more problem that I am facing. I will post it in a different thread. Thanks.
