Hi pals,
I would like to ask you guys something. I discovered that 2 bytes of characters are appended to the front of the message. Does anyone know it is a norm or exceptional? |

Let me take a guess. You're using a writeUTF method to write a string. Guess it's time to read the manual to understand what this actually does.
Cheers,

Who says it isn't. If you define this message as MQSTR, those bytes will almost certainly be corrupted.

I thought it said something about writeUTF not being translated in the manuals. Makes total sense as you would retrieve it using readUTF...
So why translate from UTF to UTF.??
Enjoy  |

| If you mark the message format as MQSTR, then the data will definitely be translated. However, the data isn't MQSTR and the two bytes of length will get translated into who knows what.... |

Hi EddieA,
Yes. Cool! You (IBM Certified Specialist, IBM Certified Developer, IBM Certified Solutions Expert) are darn right! I am using writeUTF to put messages into the queue.
I would like to seek your advice on how can I overcome this - if I write the message using writeUTF, then, am I right to say that when getting the message, I need to use readUTF?
