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:

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