[JBoss jBPM] - Change the status workflow
by magnumff
hi
I want to change the status workflow from a client external the web service (jbpm)
code:
| Object o=commandService.execute(new GetProcessInstanceCommand(17));
| ProcessInstance process=(ProcessInstance)o;
| process.signal();
|
my error is :
class org.jbpm.graph.exe.ProcessInstance
