JMS Queue in Use Error

Hi,

  I am trying to publish a message to JMS queue and consume it using flow serives without JMS triggers in 
  webMethods 7.1.2 and wMBroker as JMS provider. Created the following:

   1. Queue, Administrative Objects using JMS Admin tool
   2. Message producer service
   3. Message consumer service

 I am able to publish the message to the queue but when I try to consume it I see an error saying "JMS Queue 
 in use".

 Can you please let me know how to resolve this?

Regards,
Teja
