I am designing a service in my system based on jBPM and I am trying to make the service stateless for scalability issue. For current jBPM 3, the process instance is stateless, so I can design my stateless service to start an instance, signal the token and deal with tasks. Today when I am reading wiki page related to jBPM 4 design topics and it mentions about changing current stateless Process Instance into stateful. I am asking how will this change affect my existing design? Thanks! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4188935#...
