Hello,
I've written a Java program, trying to get Messages from a queue and storing the
message in a String.
See following code fragment:
| Code: |
MyQueue_GET.get(MyMessage_GET, gmo);
String MyMQMsg = MyMessage_GET.readString(MyMessage_GET.getMessageLength());
|
When I try to run this code I receive the following Error code.
MQJE001: Completion code 1 Reason code 2110
I think the problem is, that the message formate is not String. Can anybody
tell me what I have to do to convert the message to String?
Thanks,
Jasmin. |

First you have to determine what the message looks like.
The sample program amqsbcg, which will be installed if you installed the samples, is very helpful for this. If you're on a client installation, you can use amqsbcgc.
Then you have to determine if the message is broken because it can't be converted, or it's okay if it can't be converted (maybe it's already converted...). If it's okay, then you can code another GET that doesn't specify the convert option.

Hi fschofer,
here are the get message options:
| Code: |
MQGetMessageOptions gmo = new MQGetMessageOptions();
gmo.options = MQC.MQGMO_ACCEPT_TRUNCATED_MSG | MQC.MQGMO_CONVERT;
|
Hi jefflowrey:
I can't figure out what you mean. Do you mean that I should use the amgsgetc.exe? That doens't work because the buffer is too small for the message (header and so on...) |

No, not amqsgetc.exe or amqsget.exe.
AMQSBCG.exe or AMQSBCGC.exe.
This will browse the messages on the queue, and display the contents. It's very handy.

You have to run the program, and tell it what queue manager to connect to and what queue to read.

Ok, now I've just changed the GetMessageOptions and it's working.
Thanks for helping. |

Except now you are not converting the message. Which may, or may not, be what you want.
Did you actually look up the reason for 2110:
| Quote: |
The format name in the message is MQFMT_NONE.
A user-written exit with the name specified by the Format field in the message cannot be found.
The message contains data that is not consistent with the format definition. |
I would guess that the MQMD Format has not been set, in which case, fix the application that PUTs the message.
Cheers,
