Hi,
The jBoss transaction propagation currently only
works within the same VM that started the transaction.
When trying to import the transaction in another VM
you get the "Cannot Import Transaction" error.
You are not the only one who needs multible federated
jBoss servers, and I am currently speculating on how
this is best done in a way so we can also interoperate
with other transaction managers (in particular CORBA
OTS).
Best Regards,
Ole Husgaard.
