核心提示:1.包: package PaintBrush;/** * * @author lucifer */public class PaintBrush { PRivate String curcolor = "red"; public String getColor(){ return curcolo

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>
