I got the same problem .anyone know how to solve it?
if you mean the video with eclipse demo, it is important to start in debug mode and set a brakepoint after the ksession.startProcess. Only then the session stays in memory. If you run the ProcessTest.java just as a java application you never see a process instance in the Process Instances view.
I do not see you posted message "Registered human task listener..." and do not think this is important.
I had the same issue and solved it by upgrading to JDK 1.6+.
The user guide says JDK 1.5+ is all that is required and I happened to have 1.5.0_16 installed so I just went with that. After having the described issues (and noticing that in the demo video they are using JDK 1.6.0_14) I switched to JDK 1.6.0_16 since I had that installed already and now everything is working fine.
Also, I'm not sure if this was necessary or not but just to be safe, after switching JDKs I deleted the jbpm-installer/ folder, re-extracted the installer archive, and re-ran "ant install.demo".
Hope this helps.
There must be something else going on. I'm running on JDK 1.6.0_18 and I have the exact same problem. I set both a breakpoint at ksession.startprocess line and at the next line (logger.close();). I never see any process instances in Eclipse and the console never shows the lines
Registered human task listener
[2011:01:31 19:01:46:debug] Message receieved on client : AddTaskResponse
[2011:01:31 19:01:46:debug] Arguments : 
However, if I access the BPM console, I do see the process.
Kinda mystifying that so many people are having trouble getting the basic "helloWorld" example working....
I actually have the same problem. The ant start.demo works, I've put a breakpoint in the 'ksession.startProcess("com.sample.evaluation", params);' line, but when I go to the Eclipse view 'Process Instances', and having selected the 'kession' in the variables view, I get the same error:
"The selected working memory has no process instances"
The other tab, process instance, shows nothing.
Any help would be great!
