servlet提交到jsp页面时找不到属性
javaBean代码如下。
package mybean.data;public class Login {
private String logname = null;
private String password = null;
private String backNews = null;
private boolean success = false;

public void setLogName(String logname){
this.logname = logname;
}
public String getLogName(){
return logname;
}
public String getBackNews() {
return backNews;
}
public void setBackNews(String backNews) {
this.backNews = backNews;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public boolean getSuccess() {
return success;
}
public void setSuccess(boolean success) {
this.success = success;
}}
servlet页面代码如下：

public class HandleRegister extends HttpServlet {

}
} catch(SQLException e){
e.printStackTrace();
}
}
RequestDispatcher dispatcher = request.getRequestDispatcher("/showRegiterMess.jsp");
dispatcher.forward(request, response);

}
}
请求的jsp页面如下：
<%@ page language="java" contentType="text/html; charset=gbk"
    pageEncoding="gbk"%>
<%@ page import="mybean.data.Login" %>
<jsp:include page="head.jsp"/>
<jsp:useBean id="login" type="mybean.data.Login" scope="session"/><html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gbk">
</head>
<body bgcolor="yellow">
<center>
<font size="4" color="blue">
<br><jsp:getProperty name="login" property="backNews"/>
</font>
<%
if(login.getSuccess()==true) {
%>
<br>登陆会员名称:<jsp:getProperty name="login" property="logname"/>
<%
  }
  else {
 
%>
<br><br>登陆会员名称:<jsp:getProperty name="login" property="logname"/>
<br>登陆会员密码:<jsp:getProperty name="login" property="password"/>

}%>

</center></body>

谢谢帮个忙，servlet请求jsp页面时找不到property.
