Hi Rainer,
Thanks for the reply.
So I changed my code to create process instance to
| ProcessDefinition processDefinition =
| graphSession.findLatestProcessDefinition("websale");
| ProcessInstance processInstance = new ProcessInstance(processDefinition);
| graphSession.saveProcessInstance(processInstance);
And I know websale has been deployed.
But when i execute the above code i get the gollowing exception,
anonymous wrote : java.lang.NullPointerException: can't create a process
instance when processDefinition is null
