jsp源碼遠程教育系統_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

⑴ 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。

⑵ 求一個學習交流網站的jsp源代碼

www.enet.com

⑶ jsp登陸界面源代碼

1、login.jsp文件

<%@ page language="java" contentType="text/html; charset=GB18030"

pageEncoding="GB18030"%>

<%@ page import="java.util.*" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

</head>

<body>

<table>

<tr>

</tr>

<tr>

</tr>

<tr>

<td><input type="submit" value="登錄" style="background-color:pink"> <input

type="reset" value="重置" style="background-color:red"></td>

</tr>

</table>

</form>

</body>

</html>

2、judge.jsp文件

<%@ page language="java" contentType="text/html; charset=GB18030"

pageEncoding="GB18030"%>

<%@ page import="java.util.*" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

</head>

<body>

request.setCharacterEncoding("GB18030");

String name = request.getParameter("userName");

String password = request.getParameter("password");

if(name.equals("abc")&& password.equals("123")) {

3、afterLogin.jsp文件

<jsp:forward page="afterLogin.jsp">

<jsp:param name="userName" value="<%=name%>"/>

</jsp:forward>

}

else {

<jsp:forward page="login.jsp"/>

}

</body>

</html>

<%@ page language="java" contentType="text/html; charset=GB18030"

pageEncoding="GB18030"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

</head>

<body>

request.setCharacterEncoding("GB18030");

String name = request.getParameter("userName");

out.println("歡迎你:" + name);

</body>

</html>
