I'm taking "heuristic commit/rollback example" as listed in the wiki page. So for this example I need to figure out what to show to the users about heuristic scenario -- get a heuristic exception thrown and handle it by forget() call. So I need to create a scenario with JBM XASession where the xa commit() on XAResource can throw a heuristic exception. Then I'll tell the xa resource to forget about this transaction. I investigated out code and found it's not possible to simulate this process. So probably we drop this example for the moment?
