I've a sample program, which does an XA-transaction in MQ Server.
But i want to run it from another machine(MQ-Client), and the same XA should happen.
But the problem is in Program it refers to a Queue Manager and a Queue.
But when running it from Client it's irrelevant.(B'cze in MQ-Client we can't create a QM.!!)
The requirement as follows.
1) From Machine-A,A Java program connect to a QM in Machine-B.
2) The QM update an Oracle Database on Machine-C.
How can i do that in JAVA..?
Any kind of help is appreciated.

You can't do XA with a standard client.
You need the Extended Transactional Client, which is available from IBM at extra cost. Contact your local IBM rep for details, costs, license, etc, etc
(Pun intended!  )

But the Java code you use is going to be the same, with slightly different information passed to new MQQueueManager().
That doesn't create a queue manager!
Please read the Using Java manual.

Well....
How i could figure out my installation had an MQ Extended Transactional Clients-installed or NOT?
I mean any command / behaviour.
I had both MQ-Client 6.0 Client & Server package, with me

By asking the person who installed it, or who's job it is to know what software is installed where, in order to ensure proper compliance with licensing.
Or by checking the OS level software install registry to see if it tells you what pieces are installed.

I think you'd know - the ETC license costs about the same as a queue manager license and for that reason is fairly rare! 
If by "package" you mean the client that comes with the server, that's not the ETC. The ETC is a separate deliverable.
You don't say what platform you're on, but your best bet would be to check the installation log / registry / smit / etc

AKAIK the ETC is never bundled with the server. The client included with the server install is the standard client we all know and love, included for your convienience but also available free of charge from the IBM website.
The ETC is a separate product, purchased separately and delivered separately. From a totally personal perspective I struggle to see the cost/benefit case for using it; for what it costs you can get another server license and I believe you're better off getting another queue manager, clienting onto that and running the XA locally. This is just my view, I accept there are exceptions to this and other views may be equally valid. 
Hope this clarifies the situation.

This is a part of the installation of the MQ server on Sun Solaris (SPARC).
Do you mean that no. 6 is not the real ETC?

More likely means I don't know far enough.....

You cannot use a client to perform an XA transaction where WMQ is the transaction manager. The XA client is solely for use where WMQ is a resource manager, and the transction is managed externally, e.g. by CICS, WAS, etc.
