Hi,
I am sending correlation id in MQ headers like below
java.util.Random R1 = new Random();
byte [] corId = new byte[24];
R1.nextBytes(corId);
//
inMessage.correlationId = corId ;
but in this case when i check in IBM MQ it is coming in different way like this c756DFRTYUU. But when i print inMessage.correlationId it is showing in byte code like [B@DSER.
I want to validate like what I am sending is what i am seeing in IBM MQ. How to convert inMessage.correlationId this in to normal one like in IBM MQ. |

Please be precise.
How do you check?
How do you print?

This really isn't an MQ question rather a Java programming question. You appear to be new to Java.
There is a huge difference between a String and byte array. Also, there is no "toString" method for a byte array. And you should always seed the Random class when you instantiate it.
i.e.
| Code: |
Random R1 = new Random((new Date()).getTime());
byte [] corId = new byte[24];
R1.nextBytes(corId);
System.out.println("corId="+new String(corId)); |
It will convert the byte array to a String then print it out which will be like garbage and that is because we are dealing with a byte array and not a String.
If you want to compare what you are seeing in MQ Explorer, MQ Visual Edit or some other tool, then you need to be comparing byte array to byte array. A simple way to print out a byte array as a Hexadecimal string is to go grab my SimpleLogger and then do:
| Code: |
Random R1 = new Random((new Date()).getTime());
byte [] corId = new byte[24];
R1.nextBytes(corId);
SimpleLogger.infoDump("Correlation Id", corId); |
Which will look like:
| Code: |
2022/01/25 18:46:09.800 INFO (TestRandomBytes.<init>) Correlation Id -->>
2022/01/25 18:46:09.800 INFO (TestRandomBytes.<init>) 000000: 53C578B0 D1B519E7 74AD0C03 8AA29686 74861DFA E9CD3F85 S?x???.?t?..????t?.?????
2022/01/25 18:46:09.800 INFO (TestRandomBytes.<init>) <<----- |
Now you can compare HEX representation of Correlation Id with what you see in your MQ tool.
