[jboss-dev-forums] [Design of JBoss Transaction Services] - Re: ClientUserTransaction and TxPropogation inefficiencies

> The ClientUserTransaction is only a proxy to a real transaction on the server so JTS is irrelevant for normal clients

Unfortunately not. If a normal (i.e. without ORB) client is using UT to communicate to a server and that server is switched from the JTA to the JTS, the client will break. Of course that may be a bug rather than a design issue.

Then there is the question of what the behaviour should be when the client is using RMI/IIOP rather than JRMP for transactional calls to the server. Should it need the JBossTS libraries, or should it continue to use UT?  What if it wants to switch to JBossTS? Using either the JTA API or the CORBA API for transaction demarcation.
