javamail做用户密码找回功能出现的问题解决结果。

我做的是用户找回密码的功能 当我引入SendMail.java就出错java.lang.reflect.InvocationTargetException 解决方法是mail.jar和activation.jar没有导入

Java code

   
   
   
   

    
    
    
    
     SendMail send 
    
    
    
    =
    
    
    
     
    
    
    
    new
    
    
    
     SendMail(); 
    
    
    
    int
    
    
    
     count
    
    
    
    =
    
    
    
    send.sand(userVO.getEmail(),
    
    
    
    "
    
    
    
    密码找回
    
    
    
    "
    
    
    
    ,content,path);
