Remove the headers or extract the body? 
The additional material on the front of your message is how WMQ carries the JMS headers. It's not product specific so I'd imagine JMS can deal with it.
What have you tried so far? What happened?
Given that the message body appears to be a string, why a byte message not a text message?

The message received is an instance of BytesMessage,
| Code: |
Byte [] Bytes = new Byte[300];
String rsp = null;
if ( inMessage instanceof BytesMessage) {
BytesMessage.readBytes(Bytes);
rsp = new String (Bytes);
}
System.out.println(rsp);
|
then I print out rsp.
I want to extract the body message only. |

So why don't you?
A bit of JMS code seems to be all you need. Rather than just grabbing the entire message.

sorry I'm very new to MQ,
I don't how how to just extract part of message.
I know BytesMessage.readBytes(Bytes, length), but how do I know where to start extracting, and the length of the body message?
My version of JMS do not have getBodyLength(). |

This is nothing to do with WMQ & everything to do with JMS.

Work it out. It's really not that hard given how a JMS message is structured.

Read something about JMS & you'll realise why that's a silly question. Then be ashamed for asking a Java question so basic I know the answer.

Can somebody please remind me what JMS says about linked RFH headers?
