Hi ,
I am using WAS 6.0.2.15 and Websphere MQ 6.0 version in AIX. I am
getting error when creating a QueueReceiver Object. The Queue and Queuesession are not null in below code.This code is executed successfully in local system.I am able to place messages but I am unable to get messages because of below statement is throwing a null pointer exception
QueueReceiver qReceiver = null;
qReceiver = qSession.createReceiver(resQueue,"JMSCorrelationID = '" + correlationID +"'");
I think there is a connection problem,could you please let me know what I should be checking to resolve the problem
Below is the stack trace. Please let me know if you need more details.

Can we assume that this problem:
http://www.mqseries.net/phpBB2/viewtopic.php?p=194645&highlight=#194645
is resolved & the client is successfully installed? And that the client connection is working normally using amqsgetc or similar?
Unless you mean it works in a local system but fails when you try and get from a remote system? Which would never work?
NOTE - in this context I mean "local" to be the queue manager your application is connected to, and "remote" to be any other queue manager. Where the queue managers are physically or geographically hosted is not relevent.

Sorry, for get to mention, bec of impror installation the problem has occured. I thank you all for the support and prompt replies.We have reinstalled and now I am able to place messages, but I am not able to retreive messages from Queue.
The Queuemanager is connected in bindmode only and I am trying to retreive message from a local queue.
I meant local means in my windows system. Please let me know if you need further information. |

The problem has been solved ,I have gone through trace.log and found that they were authentication problems,that is why I am unable to retreive messages from the queue.
Thank you all for the support.
Cheers
