First, I presume you are not on J2EE for otherwise you need not go through all 
this trouble.

If you can get an instance of XADataSource, then from that you can get an 
instance of XAConnection, from which you can obtain an instance of XAResource.

Next you need to write a concrete class that extends AbstractParticipant class 
and wraps your data source. Its odd that we do not have an adapter that does 
this for you. This can then be registered with TransactionImpl. That's all 
there is to it.
