Hello, In my poc I have implemented a soa reference set of apps in two ways: 1 - using sca tuscany. 2 - using jpdl runtime library. Both products use dependency injection - however for different scopes. SCA emphasis is on service component assembly where jpdl is on the process. However jpdl does a bit of component assembly as well - not at the sca level. Here is a suggestion - why not leverage sca tuscany assembly model for referencing sca components under actions? Ideally a process definition xml can import .composite file and concentrate purely on bpm - that is what it can do best, right? Albeit - I am not the only one seeking this .... Regards, Radu.
