I am trying to deploy a code in struts 1.2 for an meta search engine . The code mapping is all fine , but the index page isnt rendered on the browser instead the code is displayed on the title bar ... any idea what could be wrong ??? The jsp page is this 

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri ="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri ="/WEB-INF/struts-bean.tld" prefix="bean" %>
<html:html>
<head>
<title>Meta Search Engine</tile>
    <html:base/>

    <head> Search Engine </head>
            <script language="javascript">
function validateCheckBoxes(){
        var yahooCheck = document.getElementsByName ('yahooCheck');
        var altavistaCheck = document.getElementsByName ('altavistaCheck');
        var microsoftCheck = document.getElementsByName ('microsoftCheck');
        var lycosCheck = document.getElementsByName ('lycosCheck');
        var askCheck = document.getElementsByName ('askCheck');

        var i = 0;
        if (yahooCheck[0].checked){
            i=i+1;
        }
        if (altavistaCheck[0].checked){

        if (microsoftCheck[0].checked){
            i=i+1;
        }
        if (lycosCheck[0].checked){

  1. 你永远不会关闭你的<title>标签。
  2. 你有两个<head>部分。
  3. 正确缩进你的代码。
  4. 考虑重构你的 JS。
  5. 考虑使用 JS 库。

您可以使用此代码。我认为它应该可以工作..而且你可以让它变得简单，而不是检查每个复选框的选中复选框计数，你可以在提交中检查它。
