I don't think I'm seeing the transaction propogation. Specifically, I'm
seeing a failure in the session bean client example. The relevant client
code is:
utx.begin();
t1.buy(50);
System.out.println("Rollback the transaction");
utx.rollback();
val = t1.read();
The call to t1.buy() appears to start and commit a new transaction rather
than using the transaction started by utx.begin(). Thus, when t1.read()
is called, the returned "val" is 50 more than expected. Following is the
trace with annotations from the corresponding source.
Thanks for your help.
