使用包含struts 2 spring和hibernate的应用程序时出现异常

Question

我正在创建一个使用struts2 spring和hibernate的应用程序。我得到的异常是上下文初始化失败

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory'
  defined in ServletContext resource [/WEB-INF/classes/sampleContext.xml]: Instantiation of bean failed; 
  nested exception is org.springframework.beans.BeanInstantiationException:
  Could not instantiate bean class [org.springframework.orm.hibernate3.LocalSessionFactoryBean]: Constructor threw exception; 
  nested exception is java.lang.NoClassDefFoundError

我的lib中有所有相关的jar
