To instantiate the class, I use spring like this <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd "> <bean id="humanTaskExample" class="org.jbpm.osgi.example.HumanTaskExample" init-method="configure"/> </beans> public class HumanTaskExample { public static void configure() { RuntimeManager manager = getRuntimeManager("humantask/HumanTask.bpmn"); ... private static RuntimeManager getRuntimeManager(String process) { // load up the knowledge base JBPMHelper.startUp(); ... The JBPMHelper class used corresponds to : https://github.com/droolsjbpm/jbpm/blob/master/jbpm-test/src/main/java/or...
