backward compensation yes, but how to roll back a message already sent via smtp? or a file transported to a remote system wich already picked that up? or even webservices (I think it will take at least a year, maybe two before ws transactions et al is seriously used in a wide environment) That is also why jbpm has not implemented this in the latest versions (it was in 2.0 but left out in 3.x) Untill then and even after then I agree with Bill that it should mainly be corrected at the business level and for that you do not need a transactionmanager, but more like a bpel or jpdl engine...
