OSGI BUNDLE ProcessEngine Configuration.

mahesh1

Hi,

I am using Activiti Engine(5.16.4) as OSGI bundle in Apache Sling.
This repository is pointed to mysql.
I wrote one more OSGI bundle, here i am using Activiti Engine services like Runtime Service, Task Service, etc.

My question is how to get process engine (Pointed to MySql) while runtime.

if i use processEngine = ProcessEngines.getDefaultProcessEngine() ;
runtimeService = processEngine.getRuntimeService();, getting NullPointer exception.

please guide me how to resolve the issue.

I'm not familiar with Apache Sling. Is there any log meesage when getting the process engine with the ProcessEngines.getDefaultProcessEngine method?

It is throwing Null pointer exception.
Caused by: java.lang.NullPointerException: null
at com.praxeva.activiti.impl.DocuvityWorkflowServiceImpl.deployPredefinedDefinitions(DocuvityWorkflowServiceImpl.java:108)

in that line code is : repositoryService.createDeployment()
    .name("Docuvity Review")
    .addClasspathResource("DocuvityReview.bpmn20.xml")
    .deploy();

i kept the logger before and after the line:

logger.info("Inside init before getting processEngine: " );
processEngine = ProcessEngines.getDefaultProcessEngine();
logger.info("Inside init after getting processEngine: " +processEngine);

log is below :
02.12.2014 17:44:54.625 *INFO* [FelixStartLevel] com.praxeva.activiti.impl.DocuvityWorkflowServiceImpl Inside init before getting processEngine:
02.12.2014 17:44:54.625 *INFO* [FelixStartLevel] com.praxeva.activiti.impl.DocuvityWorkflowServiceImpl Inside init after getting processEngine: null

Is there any logging at startup related to creating a process engine?
