使用Jbpm4.2 集成Spring 出現(xiàn)問(wèn)題：
2009-11-12 15:49:51,640 ERROR [org.springframework.web.context.ContextLoader] - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngine' defined in file [......\WEB-INF\classes\spring\applicationContext-jbpm.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.jbpm.api.ProcessEngine org.jbpm.pvm.internal.cfg.SpringConfiguration.buildProcessEngine()] threw exception; nested exception is java.lang.NullPointerException
Caused by: java.lang.NullPointerException
at org.jbpm.pvm.internal.cfg.ProcessEngineImpl.checkDb(ProcessEngineImpl.java:177)
userCommandService 為null
經(jīng)調(diào)試發(fā)現(xiàn)，使用Spring后userCommandService 確實(shí)是null，
配置中缺少什么東西？未知。 文檔中并無(wú)特殊說(shuō)明，
4.1沒有出現(xiàn)問(wèn)題~
應(yīng)該是4.2的Bug
