JSP 诡异的问题
JspRegister.jsp:(登录界面)
<%@ page contentType="text/html; charset=gb2312" %>
<html>
<head>
<title>JspRegister</title>
</head>
<body>
<form action="JspTest.jsp" method="GET">
<table>
<tr><td>姓名：<input name="userName" type="text"/></td></tr>
<tr><td>密码：<input name="userPassword" type="password" size="20"/></td></tr>
<tr><td>年龄：<input name="userAge" type="text" size="10"/></td></tr>
</table>
<input type="submit" value="Submit"/>
</form>
</body>
</html>
JspTest.jsp:
<%@ page contentType="text/html; charset=gb2312" %>
<jsp:useBean id="user" scope="page" class="jspproject.JspTestBean">
<jsp:setProperty name="user" property="*" />
</jsp:useBean>
<html>
<head>
<title>JspTest</title>
</head>
<body>
注册成功：<br />
<hr />
使用 Bean 属性方法：<br />
用户名：<%=user.getUserName() %><br />
密码：<%=user.getPassword() %><br />
年龄：<%=user.getAge() %><br />
<hr />
使用 getProperty:<br />
<hr />
使用 getProperty：<br />
用户名：<jsp:getProperty name="user" property="userName"/><br />
密码：<jsp:getProperty name="user" property="userPassword"/><br />
年龄：<jsp:getProperty name="user" property="userAge"/><br />
</body>
</html>
JspTestBean:
package jspproject;
/**
* <p>Title: </p>
*
* <p>Description: </p>
*
* <p>Copyright: Copyright (c) 2011</p>
*
* <p>Company: </p>

* @author not attributable
* @version 1.0
*/
public class JspTestBean {
public String userName;
public String userPassword;
public int userAge;
public void setUserName(String userName) { this.userName = userName; }
public String getUserName() { return userName; }
public void setPassword(String userPassword) { this.userPassword = userPassword; }
public String getPassword() { return userPassword; }
public void setAge(int userAge) { this.userAge = userAge; }
public int getAge() { return userAge; }
}
为什么红色部分设置这样的字段后会提示出错并“找不到服务器”："JspTest.jsp": org.apache.jasper.JasperException: Cannot find any information on property 'userPassword' in a bean of type 'jspproject.JspTestBean'
而将其userPassword改为password，userAge改为age却有时可以运行，但有时却“找不到服务器”为什么呢？？我是用JBuilder 2006的，太诡异了。。
[解决办法]
public class JspTestBean { public String userName; public String userPassword; public int userAge; public void setUserName(String userName) { this.userName = userName; } public String getUserName() { return userName; } public void setUserPassword(String userPassword) { this.userPassword = userPassword; } public String getUserPassword() { return userPassword; } public void setUserAge(int userAge) { this.userAge = userAge; } public int geUsertAge() { return userAge; }}
