Database Access via Telnet
1. Login 시작 실행 “ telnet ike.ie.pusan.ac.kr” ID 와 password 입력
2. Password의 수정 passwd
3. Logout exit
4. 다시 login
Database Access via Telnet
1. Database console 에 login mysql -u uXXXXX -p Password 입력
2. Database console 에서 logout quit
3. Password의 수정 mysqladmin -u uXXXXX –p password ‘YYYYYYYY’
4. Console 에 다시 login
Database Access via Telnet
1. 사용 가능한 database 보기 show databases;
2. Database 사용 use dXXXXX
3. Table 생성 create table test(no int, name varchar(20));
4. Table 확인 show tables;
5. Record 입력 insert into test values(10, ‘abc’);
6. 입력된 내용 확인 select * from test;

지금 한 것
File System Access via FTP
테스트 Web page 작성1. 시작 실행 “ notepad”
2. 다음을 입력
3. 바탕 화면에 ‘ test.html’ 로 저장
<html><body>
<h1>Hello! HTML!</h1>
</body></html>
File System Access via FTP
1. Internet Explorer 실행
2. 주소 창에 다음을 입력 ftp://ike.ie.pusan.ac.kr/webapps/
3. 파일 다른 이름으로 로그인 자신의 ike.ie.pusan.ac.kr 계정을 사용하여 로그인
4. ‘test.html’ 을 Internet Explorer 에 drag & drop
5. 새로운 Internet Explorer 실행 http://ike.ie.pusan.ac.kr:8080/uXXXXX/test.html

File System Access via FTP
1. MySQL 을 종료함
2. 현재 경로의 내용확인 ls
3. ‘test.html’ 확인 cd webapps ls

Our First JSP Programming
테스트 JSP page 작성 notepad 를 열어 다음을 입력하고 , ‘test.jsp’ 로 저장
<html><body>
<h1><%= "Hello, JSP! " %></h1>
<%String str = request.getParameter("name");if (str != null) {
out.println("You have input " + str);}%>
<hr/>
<form name="form1" method="post" action="test.jsp">Your input? <input type="text" name="name" /><input type="submit" value="OK" /></form>
</body></html>
Our First JSP Programming
1. ‘test.jsp’ 를 ike 로 전송
2. 결과 확인

Database Programming using JSP
‘list.jsp’ 의 작성<%@page import="java.sql.*"%><html><body>
<%try {
String dbUrl = "jdbc:mysql://localhost/dXXXXX?user=uXXXXX&password=YYYYYY";Connection conn = DriverManager.getConnection(dbUrl);Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM test");while (rs.next()) {
int no = rs.getInt("no");String name = rs.getString("name");out.println(no + ", " + name + "<br/>");
}
rs.close();stmt.close();conn.close();
} catch (Exception e) {out.println(e);
}%>
<p><a href="insert.jsp">insert</a></p>
</body></html>
