Hi,
I would like to know how I can separate the MQDLH form the message.
If I do:
inMessage = qReceiver.receive(Integer.parseInt(waitReponse));
String messageLu = null;
int lgMessage = 0;
if (inMessage instanceof BytesMessage){
byte reponse[] = new byte[4096];
lgMessage = ((BytesMessage) inMessage).readBytes(reponse);
messageLu = new String(reponse);
messageLu = messageLu.substring(0, lgMessage);
}
In messageLu I've got MQDLH+MESSAGE.
I just whan the MESSAGE, could some one help me.
Best regards
Ludovic |

Remember it won't be the same. Now you could use MQ to strip the DLQ header and restore the old MQMD including format, then try post the message and read it again (due to get with convert...)
Enjoy

The easiest way to ignore the DLH in JMS is to not use the DLQ in the first place, and thus ensure that you won't have to deal with messages with DLHs.
The easiest way to do this is to use a Backout Queue and backout processing to put "bad" messages on an application specific queue, rather than a system wide Dead Letter Queue (that is really only intended for messages that can't be delivered by the system).
