解决方案 »

  1.   

    <servlet-class>loginServlet</servlet-class>
    用的是类全名
      

  2.   

    那个是用的类全名哦，放在默认的包里的。现在是加入jfreechart就报action不可用，去掉那些jar包就可以
      

  3.   

    楼主看一下是不是架包的冲突啊 
    我现在就在做这个 我是直接copy的一套架包
    不知道重新导包有什么冲突
      

  4.   

    <servlet-class>src下XX.XX.具体的Servlet</servlet-class>
      

  5.   

    可能是包冲突了，我开始时把jfreechart中所有包导入的，后来只用了jcommon.jar和jfreechart.jar就可以了，至今未找到是哪些包冲突。
