Thanks, Tom. We want a simple solution to integrate our JDBC local transaction (in Tomcat) with jBPM 4 transactions. 1. Is there any "undo service" feature? 2. If not, how do you recommend that we warranty transactions integrity ? I mean, between my application and jBpm. 3. If event not, is it possible to extend jBpm to do this task ? If yes, could you give me some tips to implement that ?
