  1.   

    1. 按住ctrl键。鼠标点击 
     <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    看看能不能进去class中。。
    2. 到strust包中看看有没有这个class结果就出来了将jar放到/WEB-INF/lib下面
      

  2.   

    谢谢 这个问题 已经解决了  却是是  jar 没在lib下面   eclipse  导入的时候  怎么不会 自动放到 lib下面呢 好神奇     3Q   3Q
        
      

  3.   

    直接负责哪个jar扔到eclipse下的lib目录下去
