   <action name="loginPro"  class="com.cindy.action.LoginAction">

  在这个 <action name="loginPro"  class="com.cindy.action.LoginAction">
这行有个错误提示 
The content of element type "action" must match "((param|result|interceptor-ref|exception-
 mapping)*,allowed-methods?)".
   

Answer 1

<exception_mapping result="sql" exception="java.sql.SQLException"/>
     <exception_mapping result="illegal" exception="java.lang.IllegalArgumentException"/> 
亲,exception-mapping,不是下划线~

Answer 2

   <exception_mapping result="sql" exception="java.sql.SQLException"/>
     <exception_mapping result="illegal" exception="java.lang.IllegalArgumentException"/> 
   </action>楼上说的应该是正确。  你写成下划线了
