Hi, "mark.little(a)jboss.com" wrote : | There are no common methods/interfaces. With the exception of JSR 156 none of the compensation transaction API work has ever been standardized. WS-BA is a standard for the on-the-wire protocol (as are other WS-* standards/specifications). It doesn't define an API. Yes, I fully agree. I was only thinking of putting XTS specific code into some sort of a single component but yes - without common interfaces it would not be possible to encapsulate XTS so that it is really easily exchangeable.
