How can i get the character set (CCSID) information of a MQQueue connection using java mq api in WMQ7?
In MQ6 we are using a method called MQQueue._getConnectionCCSID() for this operation, is there any other alternative method for this MQ7. |

A queue does not have a CCSID on it's own, so the fact that you were accessing this from an MQQueue object reflects some confusion somewhere.
There is a getCharacterSet method, but it is properly on the MQQueueManager object in v7. |

Looks to me like there is confusion with java base and java JMS.
In JMS the queue (aka Destionation) can have a CCSID.
Have fun

Sure, but JMS code wouldn't be calling methods on MQQueue objects.

No but AFAIK the user code could cast the Destination to MQQueue (not the same as in java base, see package com.ibm.mq.jms)... and thus in a stack trace you might find MQQueue as the class implementing javax.jms.Queue and javax.jms.Destination, com.ibm.mq.jms.MQDestination?

The WMQv6 base Java API has an undocumented method com.ibm.mq.MQQueue._getConnectionCCSID(), which returns the queue's queuemanager's session's connection ccsid, whatever that is.
The WMQv7 base Java API does not have the same method, although it may provide an alternate, undocumented method.
It's difficult to rely on undocumented methods.
How is the returned connection ccsid used? Perhaps there's a documented alternative that would work just as well. |

Because they sometimes disappear without warning when the release changes?
