Bean:
package cn.donghaua.bean;
public class StringBean {
private String message = "No message specificed";
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
StringBean.jsp
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
