jbpm4和tomcat6整合出问题了

我开始用tomcat+spring的一个项目中加入jbpm4.jbpm4和spring终于整合成功了,因为我测试了一次,运行一个简单流程没问题。然后我启动tomcat服务器,就出现以下错误提示:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jbpmConfiguration' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.jbpm.pvm.internal.cfg.SpringConfiguration]: Constructor threw exception; nested exception is java.lang.NoSuchMethodError: org.apache.log4j.Logger.trace(Ljava/lang/Object;)V
说找不到org.apache.log4j.Logger.trace(Ljava/lang/Object;)方法,我明明引入了那个包,而且也有那个方法。对了,关于tomcat和jbpm4冲突的那几个包(juel)我都调换了,tomcat我也重新卸载重装了,问题依旧。期待那位仁兄能帮我解释一下。
附上配置文件:application.xml
