We're currently taking part in the OASIS WS-TX interoperability event around the WS-BusinessActivity specification. This is the last part of the WS-TX specification to be tested for interoperability and we can finally see the light at the end of the tunnel. It's been a long road to get here, including OASIS BTP and OASIS WS-CAF and almost 7 years of effort.
Once completed, the 1.1 version of the specifications will become a standard that will eventually be supported by all of the major Web Services vendors. At the moment and like the other participants, JBossTS supports the 1.0 specification. Expect 1.1 support from us in 2007, but note that we'll have to support both 1.0 and 1.1 for sometime to come.
