We are facing difficulties in reading messages in Mainframe. The messages are available in the mainframe queue but their format is listed in junk characters. The text messages are dropped in directly from Java/JMS application into the mainframe Queue. Please find more details below:
Server Environment: Java client is used. The WebSphere MQ 5.3 is installed in mainframe machine.
Issue: We are storing the message into mainframe Queue via JAVA. Java standalone program is able store the data and retrieve the data from Mainframe MQ. Also Java program is able to read the data from the queue which was put by mainframe. But the issue is that Mainframe could not recognize the format for the text message which was put by Java. The text message when listed in mainframe looks like JUNK value.
How can we put the message in mainframe from java so that mainframe can understand or we missing any configuration? Any help on this is highly appreciated. |

Sounds like the messages are in ASCII and as I recall the ISPF message browsing utility doesn't do a convert on the get by default.
What are you using to browse the messages on the mainframe to determine that they are 'junk'?
The fact that you can put them and read them from Java means things are fine. If you are only concerned with how they look on the mainframe then convert on the MQGET in the mainframe program |

Also you are talking about text messages. Make sure that the format is set to 'MQSTR '. You did not tell us whether you had done this.
Enjoy

If the message's MQMD.Format = MQSTR and the CCSID is correctly describing the message data, then an application (including any queue browser) which does a MQGET with MQGMO_CONVERT will see the message in a suitable format.
In JMS use TextMessage not BytesMessage for correct string handling. |

As well are you suppressing the MQRFH header when posting from Java to the Mainframe ?

I had a similar problem to this a while back. It was down to CCSID not being set:
