Do you mean the JTA component of JBossTS, or the old transaction manager? If the former, then yes it's always been designed to run outside of an application server.
I mean this:
I downloaded one of the jars there. I don;t know anything about "the old transaction mnanager". Could you point to any resources?
Is the JTA compoenent I have work standalone?
Thanks for the answer.
JBossTS can be used stand-alone. That includes the JTA component. Check the docs and examples. Check the labs pages. Check the wiki.
