  | public static  void startProcessDefinition() {
  | 		String processDefinitionName = new String("websale");
  | 		JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();
  | 		JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
  | 		try {
  | 			GraphSession graphSession = jbpmContext.getGraphSession();
  | 			ProcessDefinition definition = graphSession.findLatestProcessDefinition(processDefinitionName);
  | 			ProcessInstance instance = definition.createProcessInstance();
  | 			instance.signal();
  | 			jbpmContext.save(instance);
  | 		} finally {
  | 			jbpmContext.close();
  | 		}
  | 	}
  | 

error has beeb occured
