What do you mean? UserTransaction is JTA not JTS.

The ClientUserTransaction is only a proxy to a real transaction on the server
so JTS is irrelevant for normal clients.

If there is a transaction manager on the "client" then we use
ServerVMClientUserTransaction which is just a wrapper for that JTA implementation.

UT.begin() -> TM.begin()
etc.

Of course whether/how that "client" will propogate the TPC to the real server
maybe an issue you need to resolve, but it is irrelevant whether
the transaction was started using the UserTransaction api or some
other use of the client's TM.
