<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><! DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN""http://www.w3.org/TR/html4/loose.dtd" ><%@ taglib prefix="s" uri="/struts-tags"%>< html>< head>< meta http-equiv="Content-Type" content="text/html; charset=UTF-8">< title>Example Label Tag</title></ head>< body>label1: <s:label value="Roseindia" /><br>label2: <s:label value="Technology" /> <br> <s:textfield label="Roseindia"/><br> <s:textfield label="Technology"/></body> </html> |
