    Invalid Selector

    Sebastian Pätzold Newbie

      Hi all,

      I got following error with JBoss messaging:

      15:29:00,896 WARN [Selector] Invalid selector: JMSCorrelationID=1179926940029
      java.lang.Exception: Bad Object: expected 'String' got 'Long' for operation: 0:EQUAL(

      If I'm not wrong, apparently the attached systems tries to retrieve a message via a JMSCorrelationID which is not a string but a long. Is there a possibility to make this work? Of course I can't do anything in the source code of this attached ERP system.

      Thanks for your help...

          How about adding quotes to your selector?

          JMSCorrelationID='1179926940029'
          


          BTW are you sure you want to be be using selectors for something as dynamic as correlation ids? Setting a consumer with a selector is likely to be a fairly slow operation (compared to sending/receiving a message) and probably not something you want to do to implement a request/response pattern.

          Have you considered using temporary queues instead?

            Thanks for the tip. However I can't do anything on the side of the application which uses the odd correlation id or the selector as it is closed source. So I have to deal with that in JBoss messaging. Any ideas to that?

            I guess that the correlation id is a string is part of Sun's JMS spec?

              The selector is invalid, you need to fix your application - this is not a JBM issue.

              Yes, http://java.sun.com/j2ee/sdk_1.2.1/techdocs/api/javax/jms/Message.html#getJMSCorrelationID()
