<%@page contentType=“text/html;charset=UTF-8”>
<HTML>
<head>
<title> Zhao Lei home page </ title>
<body>
<%
request.setCharacterEncoding(“utf-8”);
String aName = request.getParameter(“name”);
request.setAttribute(“value”,aName);
%>
String iNsert = request.getParameter(“insert”);
<%
<H1> Welcome to my home page </ h1>
<img src = "Image / zhaolei.jpg" alt = "twentyOnePolits" width = "350">
<the p-> hedgehog who Hello everyone, I'm Zhao Lei, you it? </ P>
<from Method = "POST">
<%
IF (the request.getAttribute ( "value") == null) {
%>
< input type=“text” name=“name” value=" “> value=”<%=request.getAttribute(“value”)%>" >
<%
}else{
%>
< input type=“text” name=“name” value="<%= request.getAttribute(“value”)%>" >
<%
}

< /form>
<%
if(aName !=null && aName.trim().length() >0 {
%>

<%= aName %>
<%=iNsert%>
<%
}
%>
< /body>
< /html>
