Answer 2

<html:form action="/user/logon" focus="username"> 
此句改为：
<html:form action="/user/logon.do" focus="username"> 

Answer 3

在调用Action的时候没有指定调用哪个方法
parameter="logon_no" 

Answer 4

public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
System.out.print("ssssssssss");
ActionForward forward=new ActionForward();
String =mapping.getParameter();
if(.equals("logon_no"))
forward=executeLogonNo(mapping,form,request,response);   
           if(.equals("index"))
             forward=executeIndex(mapping,form,request,response);     
         return forward;
}

Answer 5

关于parameter="logon_no" 设置
在LogonAction中是不是需要加上一个方法？如下：
public ActionForward logon_no(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { 
.....
}

Answer 6

  logon_no() 方法是存在的
