Outline

Introduction Servlet and JSP Oracle and JDBC

Project Goal Installation of JSP server Installation of Oracle8i

Servlet

Read explicit data sent by client (form data) Read implicit data sent by client (request

headers) Generate the results Send the explicit data back to client (HTML) Send the implicit data to client (status codes

and response headers)

JSP Java Server Pages (JSPs)

Use regular HTML for most of the page Mark dynamic content with special tags

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<HTML><HEAD><TITLE>Welcome to Our Store</TITLE></HEAD><BODY><H1>Welcome to Our Store</H1><SMALL>Welcome,<%= Utils.getUserNameFromCookie(request) %>To access your account settings, click<A HREF="Account-Settings.html">here.</A></SMALL><P>Regular HTML for rest of on-line store’s Web page</BODY></HTML>

Oracle

Client/Server Large databases Support concurrent accesses from a large

number of users High transaction processing performance High availability Openness, industry standards Manageable security Distributed system

JDBC

Java Database Connectivity A standard or open application programming

interface (API) for accessing a database from JAVA programs.

Allow Java to run and process SQL Select, Update, Insert, Delete, and …

Oracle JDBC Thin driver Use Java socket to connect directly to Oracle Provide its own implementation of a TCP/IP version of

Oracle’s Net8

Project Goal Install

Linux: Redhat7.2 JSP server: Tomcat3.3 Database: Oracle8i (8.1.7)

Write a test servlet Retrieve the data from database and show the result on

client’s browser

JSP Server: Tomcat Installation

Download Tomcat3.3 Unzip it Make sure the path includes the JDK bin

directory. Update the CLASSPATH to include

install_dir\lib\servlet.jar install_dir\lib\jasper.jar

Problems NONE!

What we learned TOMCAT is great!

Oracle8i

Pre-Installation Create group dba and oinstall Create user oracle and add it to these two

groups Make sure jdk1.1.8_v3 is installed under

/usr/local Create installation directory, /u01, with

ownership of oracle Login in as oracle and modify

the .bash_profile file under its home directory(/home/oracle)

Oracle8i (Cont.)

Installation Download oracle8.1.7 and unzip it Run the universal installer, runinstaller.sh Follow the instructions on the screen to finish the

installation of Oracle Enterprise Edition

Problems The installation files are actually buggy Oracle9i requires large memory and disk space

What we learned Installing Oracle8i on Redhat7.2 is reasonably tough

Test Servlet

Function Establish network connection to Oracle via

JDBC driver Retrieve all the records of table Employ in

Oracle 8.1.7 Show the retrieved data from Oracle in a HTML

table in user’s browser
