[jbpm-issues] [JBoss JIRA] Resolved: (JBPM-2645) Problem to instanciate ProcessEngine in 4.2

Problem to instanciate ProcessEngine in 4.2 ------------------------------------------- Key: JBPM-2645 URL: https://jira.jboss.org/jira/browse/JBPM-2645 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: jBPM 4.2 Reporter: Alexandre Navarro Assignee: Joram Barrez Fix For: jBPM 4.x When I want to instanciate my project engine, I have an exception. It was working in 4.0 and 4.1 but not in 4.2. I think it is because a field must be setted in jbpm but I don't which. Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngine' defined in class path resource
