1.包：

package PaintBrush;

/**
*
* @author lucifer
*/
public class PaintBrush {
     PRivate String curcolor = "red";
     public String getColor(){
          return curcolor;
     }
     public void setColor(String color){
          curcolor = color;
     }
}

2.jsp代码：

<%--
    Document   : TestSetPro
    Created on : 2009-10-3, 15:02:50
    Author     : lucifer
--%>

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<jsp:useBean id="brush" class="PaintBrush.PaintBrush"/>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
         Original Color:
         <jsp:getProperty name="brush" property="color"/>
         <br>
         Changed Color:
         <jsp:setProperty name="brush" property="color" value="blue"/>
         <jsp:getProperty name="brush" property="color"/>
    </body>
</html>
