Have you tried the java.lang.String getBytes() method?

You do not specify which API c, java base, java JMS etc...
Anyway I would say this is a bad design. You should let MQ assign the MessageID. On top of this MessageId and CorrelationId are always treated as byte arrays. Forget about string. In this case string has no meaning because there is no conversion accross platforms and CCSIDs.
So what looks like "mymsg" on one plattform my come accross as "@!%#*" on the other !
Enjoy  |

A couple of things to keep in mind.
If you are using JMS - you can not set the MsgId. The JMS Provider always sets this to a unique value when you execute a send.
Using MessageId as a selector in any other pattern than request/reply is an anti-pattern - it is treating a queue as a database and queues are not databases.
Also, it is likely hiding complexity that is much better off being visible.
