i am using activiti version 6.

i created a bpmn process from activiti-app

then i want to strart that process from activiti-rest.war using the api

request body :

     "returnVariables": false

header :

as i see in the LOG process is being started in tomcat threads.


refering latest github code:




when i see method


@RequestMapping(value = "/runtime/process-instances", method = RequestMethod.POST, produces = "application/json")
  public ProcessInstanceResponse createProcessInstance(@RequestBody ProcessInstanceCreateRequest request, HttpServletRequest httpRequest, HttpServletResponse response) {

 i can see process is being started  and not waiting for process to complete , http response is 201. i can understand request is not being hold for process instance to complete

 instance = processInstanceBuilder.start();


please refer the log snipped below, i can see process is executing in server thread and request is waiting till process completed
