Can you share maven project with is to replicate issue and complete stack trace ?
That error got resolved now,There were some error with bpmn flow.
Now I am getting other exception "Could not find work item handler for Human Task".
Any idea? How to create work item handler? I have a user task in the bpmn flow and i did input data mapping . how to add form to the user task?
What are you doing exactly? Are you creating a KieSession manually to run a process? I recommend you to look at the jbpm services that set up the session with all the handlers needed by the processes to run. If not you will need to register a Handler for the Human Tasks (User Task Nodes). You can do that by ksession.registerWorkItemHandler("Human Task", <your implementation of the WorkItemHandler interface here>);
the bpmn flow have user task as the start node.I need user to enter details on a form and get those details to further nodes for processing.when i generated the forms, ftl got generated.but i didn't set these files on any tasks.
I am executing the application in Eclipse.During the execution ,it throws an exception "org.drools.core.WorkItemHandlerNotFoundException: Could not find work item handler for Human Task" .
I am totally new to jBPM and working around with simple applications.
I recommend you to take a look at the documentation or even find a book about jBPM in amazon. That will help you to get started.
