//1, the release process
@ Test
Public void deploy () {
//get the process engine
ProcessEngine ProcessEngine=ProcessEngines. GetDefaultProcessEngine ();
Deployment Deployment=processEngine. GetRepositoryService (.) createDeployment () addClasspathResource (" diagrams/dbglProcess. BPMN "). The deploy ();
System. Err. Println (deployment. GetId () + "" + deployment. The getName ());
}

//2, start the process
@ Test
Public void startProcess () {
//get the process engine template
ProcessEngine ProcessEngine=ProcessEngines. GetDefaultProcessEngine ();
//start a process
//use the process definition of the key to start the process instance, the default will be according to the latest version of the startup process instance
ProcessInstance PI=processEngine. GetRuntimeService (.) startProcessInstanceByKey (" dbglProcess ");
System. Err. Println (" pid: "+ PI. GetId () +", activities: "+ PI. GetActivityId ());
}

Code as above, execute to the third line ProcessInstance PI=processEngine. GetRuntimeService () startProcessInstanceByKey (" dbglProcess "); Times wrong, error message below
