學校網站源碼jsp
Ⅰ jsp 中網站的首頁源代碼
這是最簡單的一個例子，資料庫要你自己建，用的是ACCESS

Ⅲ 網頁源代碼是什麼
1、網站的源碼：可以理解為網站源程序的代碼，或是傳到網站空間可以直接使用的程序代碼。
2、網站源碼分為兩種，一種是動態源碼如：ASP，PHP，JSP，.NET，CGI等，一種是靜態源碼如：HTML等。
Ⅳ 求jsp登錄源碼 急急急急急急急急急急急
登陸頁面 index.jsp源碼：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

Ⅳ 網上下載的JSP網上選課系統（源代碼）怎麼在自己的電腦運行
下載tomcat並打開tomcat/bin/starup.bat 把代碼放進tomcat/webapps。 用瀏覽器輸入 這樣的地址 http://127.0.0.1:8080/book/teacher.jsp 我的代碼在 tomcat/webapps/book/teacher.jsp，可以在webapps 裡面建文件夾。
Ⅵ 急求網上招生/報名系統jsp源代碼
之前寫過一個用於中小學的網上招生報名系統
不是純JSP代碼啊, 那個都是老黃歷了, 現在的課程設計一般都是servlet+JSP+jdbc搞定, servlet封裝一個簡單的dispatcher就行
