4.2. ProcessRuntimeService
It is designed to work with process instances. The service methods allow you to:
-  
cancel a process
 -  
complete a task
 -  
assign a task to the user
 
When a process is started, the following process variables are created automatically:
-  
bpmProcInstanceId-ProcInstanceobject ID -  
entityName- linked entity name -  
entityId- linked entity ID 
To access the service functionality on middleware, use the ProcessRuntimeManager bean.
