How to access a remote JMS queue from a client program?

On system X (with SAP XI and Web AS server installed) messages are written to a JMS queue. Connection factories, queues etc. are defined and created only on system X.

Now I want to access this JMS queue from a client program running on another system Y (where both SAP Netweaver Developer Studio and Web AS are installed).

What must I do in order that the client program on system Y can access the queue on system X? Do I have to create a connection factory and a queue on system Y though I want to access those on system X? Are there written instructions and example Java programs for this scenario?
