Dera Kris,
Thank you so much for your reply. I guess the problem is related to my Java code. Could you please help me take a look at it? I attached my test project "HelloJBPM.zip" to the article on the first floor.
I appreciate your help so much!
I tried your example, there are some errors:
1) seems my code could not call: ServiceTaskHandler(), even I import org.jbpm.bpmn2.handler.ServiceTaskHandler;
2) my code could not identify <serviceTask; I am using <task id="_4" name="RecordHandler" tns:taskName="Handler" >, is it because of different version?
Thanks you so much!
