MSGID and CORRELID are not character fields; rather, they are MQBYTE24 fields, which means that they are just 24 bytes of bits, and do not have a character representation.

There are numerous programs on google showing how to represent the value of a byte as a hex string from 00 to FF.
You cannot convert the byte array to a string you can only represent it in a string form (00-FF)
Enjoy

| The amqsbcg sample program dumps the message id and correlation id out. You might want to look at it as well. |

The example in the linked thread was kind of messy so here's an easier way to do it (where b[] is your byte array of any size):
| Code: |
String msgId = "";
for (int i = 0; i < b.length; i++) {
msgId += Integer.toHexString((b[i] & 0xff) + 0x100).substring(1);
} |
The 0x100 add & substring is to deal with leading zeroes which toHexString strips. |
