I found some code about it on this forums.But when execute this code the error has been occured.
here is code for starting process:
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
