I'm relatively new to jBPM and am walking some similar ground to you.
- Perhaps to test the simple process you could add a timer task after the "hello world" with a delay of say 30s, and a second script task ("goodbye world"?). This should give you some time to check the status.
- Are you running everything on a single system? A few days ago I was getting "Loaded 0 instances" when I was running over the internet between my office and our company headquarters and I think this was down to the network being especially slow and something timing out.
- System.out.println seems to go to the server log file jboss-as-7.1.1.Final/standalone/log/server.log (If anyone know a neated way to redirect I'd be grateful)
Hope this helps
