More Newbie questions.  I created a simple process in Guvnor's Process Designer.  The process validated and the package built without errors.  The process shows up in the jBPM Console, but when its selected and the Start button is pushed, the debug message said

2013-04-24 16:17:50,209 [DEBUG] POST: http://localhost:8080/gwt-console-server/rs/process/definition/davespackage.AnalyticServices/new_instance http://localhost:8080/gwt-console-server/rs/process/definition/davespackage.AnalyticServices/new_instance
2013-04-24 16:17:50,251 [DEBUG] GET: http://localhost:8080/gwt-console-server/rs/process/definition/davespackage.AnalyticServices/instances http://localhost:8080/gwt-console-server/rs/process/definition/davespackage.AnalyticServices/instances
2013-04-24 16:17:50,275 [INFO ] Loaded 0 process instance(s) in 4 ms

What could cause the console to not load the process, even through it shows up in the process list?

that could indicate that process was completed within the request - for example where there are no wait states such as human task. So by the time requests comes back to the UI process is already completed. Console shows only active process instance.

Well, below is a very test process to see if the JBPM Console would display a simple "Hello World" (Java).  So, even if the task were to complete quickly, is there a console where I would see, "Hello World" displayed?  Where would the JBPM Console display "Hello World" or would it?

David

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

Thanks, Andy.  I looked in the log and saw the hello world.  I'm just running on a laptop at this point, though it will be across a network eventually.  I'll test with a timer task to see how that goes.
