I'm writing a MQ-Java program, which sends a group of messages. It prints out the groupId after putting a message. I've cheeck the groupIds of all messages are same using MQ Explorer. But the values of groupId printed in this program are different from each other. Could anyone tell me what's wrong with this program? How can I check groupId?

message.groupId = MQC.MQGI_NONE;
message.messageFlags = MQC.MQMF_MSG_IN_GROUP;

while ( (rl = fis.read(ch)) != -1 )
{
message.clearMessage();
message.writeString ( byte2String(ch) );
if ( rl != messageMaxLength )
message.messageFlags = MQC.MQMF_LAST_MSG_IN_GROUP;

queue.put ( message, pmo );
System.out.println ( "groupId = " + message.groupId );

}

I think the message.clear is what is doing it. You should only be resetting the messageid and/or correlid fields in the message header, not the whole thing. This way, the groupid field remains set to the value that was assigned to the first message in the group.
