I'm trying to run a distributed transaction on two Derby instances using
a my application program as the transaction manager. I'm stuck on how to
create a global transaction id that I can pass to the start method of
the XAResource object that I get from the XAConnection object (an
instance of NetXAResource).
I've searched for examples but both that I found used external classes
to create the Xid. Looking at the Derby code the most likely candidate
seemed to be org.apache.derby.client.ClientXid but I have no idea what
to pass to the constructor. The best example I found on an IBM site used
com.ibm.db2.jcc.DB2Xid. I've not found any Derby-specific examples of
how to create an Xid.
Any pointers much appreciated.
Thanks
Mick Jordan
