jbpm 与ssh整合 无法创建processEngine---闹心中
整合已经一天了 上网找了各种资料 怎么都不行各种问题
步骤都一点一点的做 就是不对 各位高手指点一下

tomcat启动时就出错
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'processEngine' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [protected org.jbpm.api.ProcessEngine org.jbpm.pvm.internal.processengine.SpringHelper.createProcessEngine()] threw exception; nested exception is java.lang.AbstractMethodError: org.apache.xerces.dom.ElementNSImpl.setUserData(Ljava/lang/String;Ljava/lang/Object;Lorg/w3c/dom/UserDataHandler;)Ljava/lang/Object;
