Ouch! I wrote much of the Weblogic server's distributed transactions framework back in the day. Forget EJB (which too I wrote :(, but in my defense it was forced on us by IBM and Oracle, and I personally hated it). The JTA bit was a thin sliver over the various db and messaging product vendors' XA drivers, which differed in important and annoying ways. Some were not thread-safe (SQLServer), some drivers' connections had to be pinned to the same thread (Informix) etc. As a user, if you had to have distributed transactions, you would have done worse than Weblogic, methinks.
