  1. JSP 簡介

  2. Outline • 什麼是JSP? • JSP運作模式 • 安裝JSP • JSP範例一 • JSP範例二

  3. 什麼是JSP? • Java Server Pages • 用來開發 “含動態內容網頁”的技術

  4. JSP運作模式 JSP File Request Resource Response HTMP File HTMP File

  5. 安裝JSP 需安裝 j2sdk-1_4_0_03-windows-i586.exe http://java.sun.com/j2se/1.4/download.html jakarta-tomcat-4.1.18.exe http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/

  6. 安裝JSP • 設定環境： • WINDOW98： • 改c:\config.sys，加入以下設定 • SHELL=C:\COMMAND.COM /E:4096 /P • 改c:\autoexec.bat，加入以下設定 • SET PATH=C:\JDK\BIN;%PATH% • SET JAVA_HOME=C:\JDK • SET CATALINA_HOME=C:\TOMCAT • SET CLASSPATH=C:\JDK\lib\ • WINDOW2000及XP： • 開始→設定→控制台→系統→進階→環境變數 • 編輯系統變數PATH，加上C:\JDK\BIN。 • 新增變數CLASSPATH，值輸入C:\JDK\LIB。

  7. 參照網址 • Java 1.4 API • http://java.sun.com/j2se/1.4.1/docs/api/

  8. JSP範例一 • <%@ page contentType="text/html;charset=big5"%> • <%@ page import="java.util.Date" %> • <html> • <head> • <meta http-equiv="Content-Type" content="text/html; charset=big5"> • <title>Test1</title> • </head> • <body> • <% • Date Clock = new Date(); • out.println(“現在是 ”+Clock.getHours()+“點鐘!"); • %> • </body> • </html>

  9. JSP範例二 • 輸入密碼 密碼錯誤 Test2a Test2b 程式 送出Request 密碼判斷 輸入密碼 Test2b Html 密碼正確

  10. JSP範例二(Test2a) • <%@ page contentType="text/html;charset=big5"%> • <%@ page import="java.io.*" %> • <HTML> • <HEAD> • <TITLE>test2a</TITLE> • <META content="text/html; charset=big5" http-equiv=Content-Type> • </HEAD> • <BODY> • <center> • <form name="form1" method="post" action="Test2b.jsp"> • <input type="password" name="passwdofMT" size="16" maxlength="16"> • <input type="submit" name="b1" value="確定"> • </form> • </center> • </BODY> • </HTML>

  11. <%@ page contentType="text/html;charset=big5"%> <%@ page import="java.io.*" %> <% String passwd=request.getParameter("passwdofMT"); boolean LogOk=false; if (passwd.equals("1234")) LogOk=true; if (LogOk==false) { response.sendRedirect(response.encodeRedirectURL("Test2a.jsp")); } else { %> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=big5"> <title>Test2b</title> </head> <body> <center> <font size=4 color="#0000FF"><b>你進來了!!</b></font><br> </center> </body> </html> <% } %> Test2b
