ABSTRACT

In this project I will simulate an online real

estate company using JSP Java Servlet and JavaBean

technology It is not as complicated as an online

company in the real world but it includes all the

basic functions that an online company needs This

online real estate company - SweetHome - is a

brokerage agent that provides easy online solutions

for house buyers and sellers Properties information

will be stored in a Relational Database for the users

to search The customer can register as a new member

or even only just as a guest on line

I designed the system to use a 3-tier

architecture In the client tier users can access

various information and services through a web

browser In the Application server tier I use JSP and

Java Servlets In the business logic tier I use

JavaBeans to connect to the database by JDBC

JSP (JavaServer Page) is an extension of the Java

servlet technology from Sun that provides a simple

programming vehicle for displaying dynamic content on

a Web page Java Servlet is a Java application that

iii

runs in a Web server or application server and

provides server-side processing typically to access a

database or perform e-commerce processing

JavaBean is a reusable software component that

can be visually manipulated in builder tools I use

JavaBeans in the web application tier to communicate

with the MySQL database in the database server tier

The goal of this project is to use JSP Java

Servlet and JavaBean technologies to design and

implement the SweetHome system

CHAPTER ONE

INTRODUCTION

11 Introduction

Web based application is becoming more and more

popular these days Many dot com companies such as

Amazon eBay and other online companies provide their

business services through the Internet Customers can

log into a companys web site to purchase goods and

services Online companies can provide their

information and services without opening a real retail

store


estate company This online real estate company -

SweetHome - is a brokerage agent that buys and sells

properties especially houses in California

SweetHome provides basic functions for those who want

to find appropriate properties or brokers through the

Internet Customers can search property in the

SweetHome website They can also choose their brokers

depend on what language the customers speak as well

as the brokers experience and sale records etc

After registration if customers want to buy or sell

1

their houses they can make an appointment with their

brokers

The most two popular platforms for web

application development are Microsoft NET and Java

J2EE I choose the Java platform in this project is

based on the following reasons

First it works on multiple platforms once you

finish the web application you can run it both on

Linux or Windows

Second it is an open source you can download

the J2SE or J2EE from Suns website for free

Third it is object oriented compared to C++ and

Visual Basic Java is an object oriented language

Thus I chose to use Java related technologies to

implement this system

12 Scope

SweetHome will provide services and information

for customers who want to buy or sell their houses

This online real estate company could support two

kinds of scenarios

First the customers are property buyers The

application will provide the interfaces so that the

2

buyers can search the properties on the market find

the appropriate office and broker register them on

the web site and make an appointment with their

broker

Second the customers are property sellers The

scenario for the sellers will be the same as the one

for buyers except for searching for properties

The application starts with customers logging

into the web site and ends with customers logging off

the web site

CHAPTER TWO

SYSTEM ARCHITECTURE

21 The 3-tier Architecture

The infrastructure of SweetHome is a 3-tier

architecture (See Figure 1) using web technologies

including multi-platform browsers JavaBean HTTP

servers HTML documents JSP Java Servlet and JDBC

access to Relational Databases

I considered several other architectures

available for this project such as the 2-tier

architecture The 2-tier architecture is the

traditional idea of a client-server system Usually

this architecture combines both presentation logic and

business logic together in one tier The server

provides persistent storage via a database

The 3-tier architecture separates out the

presentation logic from the business logic (which

resides on a middle-tier system) Considering the

scalability and flexibility for this business I

decide to set up a 3-tier web deployed architecture

There are many advantages of using a 3-tier

architecture with the web

7

First The 2 -tier architecture does not have an

application server tier Business-objects that

implement the business rules live here and are

available to the client-tier This tier protects the

data from direct access by the clients

Second as the Internet and Intranet become more

and more powerful and widely-used in business and

daily life the World Wide Web is the perfect place to

advertise the products

Third the cost of setting up a site is

reasonable and affordable ($70 to obtain a domain name

for first 2 years and $35 per year after 2 years)

Finally a system deployed through the World Wide

Web can avoid the hassles of client-software

installation and upgrades Clients simply need access

to a browser which can be downloaded free of charge

from the web The security scalability and platform

independence are the main reasons why I rejected the

2-tier architecture

22 Client Tier

The web browser is the minimalist client that

sends users requests and interprets information it

receives from a server and displays it graphically to

a user The client is simply there to interpret the

servers commands and render the contents of a HTML

page to the user Web Browsers are primary

interpreters of HTML syntax The browser executes the

HTML commands to properly display text and images on a

specific GUI platform Users navigate from one page to

another using the embedded hypertext links

In this project I needed to develop a website

that contained the main page and a pop-up window for

mobile users to login to the Internet

Operating System

This is a client platform independent system The

client can use any operating systems such as Windows

9598NT2000XP workstation Mac OS OS2 UNIX

Linux etc Netscape Navigator 30 or higher or

Microsofts Internet Explorer 3x or higher is

required to view the HTML documents and web forms on

the Web Server

10

23 Application Server Tier

A World Wide Web server is simply a program that

answers requests for documents from World Wide Web

clients over the Internet All World Wide Web servers

use a language or protocol to communicate with web

clients called the Hyper Text Transfer Protocol This

is where the http in a web URL comes from All types

of data can be exchanged using this protocolincluding

HTML graphics sound and video Web clients convert

open URL commands into HTTP GET requests

Considering the performance issue which is

basically the waiting time and also about the budget

issue which has to be pressed as low as possible this

project was designed to run in Jakarta Tomcat 401

web server

SweetHome web site is not a very heavy site that

provides thousands of services to people This is

different from sites such as yahoocom which has yahoo

games yahoo maps online shopping chatting

messenger and so on Tomcat web server which is the

product of Jakarta project from Apache is offered for

free by downloading directly from the Apache website

11

httpj akartaapacheorg Moreover Tomcat also

supports Servlets and JSP programming which are the

main technology used in this project

24 Database Server Tier

Of course every system must have a place to

store and retrieve massive loads of data I decided

to use MySQL 323 as my DBMS server

MySQL is free software and there are different

versions that can run on Windows MacOS Solaris HP-

UX AIX and Linux It supports APIs for C C++

Eiffel Java Perl PHP Python and Tel It provides

very fast joins using an optimized one-sweep multishy

join You can connect to MySQL by running a middle-

tier separate application server that has a MySQL

driver

25 Middleware Services

Middleware starts with the API set on the client

side that is used to invoke a service and covers the

transmission of the request over the network and the

resulting response In N-tier environments middleware

must provide a platform for running server-side

12

components balancing their loads managing the

integrity of transactions maintaining high-

availability and securing the environment Here are

two general middleware systems

Object-Specific Middleware - The Hypertext Transfer Protocol

The Hypertext Transfer Protocol (HTTP) is an

application-level protocol for distributed

collaborative hypermedia information systems It is a

generic stateless object-oriented protocol that can

be used for many tasks such as name servers and

distributed object management systems through

extension of its request methods A feature of HTTP is

the typing and negotiation of data representation

allowing systems to be built independently of the data

being transferred HTTP has been in use by the World-

Wide Web global information initiative since 1990

Database-Specific Middleware - Java Database Connectivity

JavaSofts Java Database Connectivity (JDBC) is

an API that lets you access virtually any tabular data

source from the Java programming language It provides

cross-DBMS connectivity to a wide range of SQL

13

databases (See Figure 2) It makes Java codes DBMS^-

independent Almost all of main database vendors

provide their own JDBC drivers in multi-platform

Therefore at most time the database operation

program written in java with JDBC is easy to be

migrated to many kinds of platforms without changing

the code

CHAPTER THREE

JAVASERVER PAGE JAVA SERVLET

AND JAVABEAN

31 JavaServer Page versus Active Server Page

JavaServer Pages (JSP) and Microsoft Active Server

Pages (ASP) technologies have many similarities Both

provide a simplified fast way to create web pages

that display dynamically generated content But they

also differ significantly in some ways Here are some

main strengths of JSP as compared to ASP

Portability

JSP is being developed by Sun Microsystems and is

designed to be both platform and server independent

(See Table 2)

Therefore it has Write Once Run Anywhere

capability In contrast ASP is purely a Microsoft

based technology deployed primarily on Windows

servers JSP technology was designed to support

numerous servers browsers and tools For example

Apache web server which hosts more than 70 of the

15

websites worldwide will now fully support the JSP

technology So you do not have to worry about your OS

being Windows or Linux

Reusability

Most JSP pages rely on reusable cross-platform

components (See Table 2) to perform the more complex

processing required of the application Developers can

instantiate JavaBeans components set or retrieve bean

attributes and perform other functions that are

otherwise more difficult and time-consuming to code

They also can share and exchange components that

perform common operations or make them available to

larger customer communities The component-based

approach speeds overall development and lets

organizations leverage their existing expertise and

development efforts for optimal results

Performance

The JSP page is compiled into a Java Servlet class

and remains in server memory after it has been called

for the first time so subsequent calls to the page

have faster response time whereas in ASP the page needs

to be recompiled for every request

16

Custom Tag Libraries

The JSP technology is extensible through the

development of customized tag libraries The web page

developers can create custom tag libraries so page

authors can access more functionality using XML-like

tags and depend less on scripting With custom tags

developers can shield page authors from the

complexities of page creation logic and extend key

functions to a broader range of authors

32 JavaServer Page

Java Server Pages (JSP) is a server-side

scripting language which is based on the Servlet

framework and allows combining of HTML text with Java

source code in the same document The suffix

traditionally ends with jsp to indicate to the web

server that the file is a JSP file JSP is a server

side technology - you can not do any client side

validation with it

JSP sits on top of a Java servlets model and

makes working with HTML easier It allows developers

to mix static HTML content with server-side scripting

to produce dynamic output By default JSP uses Java

as its scripting language however the specification

allows other languages to be used

To offer the best of both worlds - a robust web

application platform and a simple easy-to-use language

and tool set - JSP provides a number of server-side

tags that allow developers to perform most dynamic

content operations without ever writing a single line

of Java code So developers who are only familiar with

scripting or even those who are simply HTML designers

18

can use JSP tags for generating simple output without

having to learn Java Advanced scripters or Java

developers can also use the tags or they can use the

full Java language if they want to perform advanced

operations in JSP pages

JavaServer Page Request Model

HTTP requests are processed under the JSP model

In the basic request model a request is sent directly

to a JSP page Figure 3 illustrates the flow of

information in this model JSP code controls

interactions with JavaBeans components for business

and data logic processing and then displays the

results in dynamically generated HTML mixed with

static HTML code

Web server with JSP engine

Figure 3 Basic JavaServer Page Request Model

The beans depicted can be JavaBeans or EJB

(Enterprise JavaBeans) components Other more

19

complicated request models include calling out to other

JSP pages or Java servlets from the requested JSP page

In this project I wrote branchjsp brokerjsp

brokerprofilejsp and etc (See Figure 4 and Appendix

B) to handle the users input from the browser and

display the dynamic result For example in the office

search page when customers select one of the

SweetHomes offices the branchjsp will handle the

request and display the result

JSP files actually get compiled into Servlets

Some benefits can be acquired by writing JSP instead of

just the Servlets For example Java and the JSP

extensions assist in making the HTML more functional

Servlets on the other hand allow outputting of HTML

but it is a tedious process The other benefit is

easier to make a change in the HTML format

20

brokerprofilejsp

Figure 4 JavaServer Page and Servlet Flow Diagram

sellhtml

21

33 Java Servlet

Servlet are modules of Java code that run in a

server application (hence the name Servlets similar

to Applets on the client side) to answer client

requests and extend requestresponse oriented servers

such as Java-enabled web servers Even tough servlets

are not tied to a specific client-server protocol but

they are most commonly used with HTTP and the word

Servlet is often used in the meaning of HTTP

Servlet

In this project appServlet makeAppservlet and

forgetidServlet etc (See Figure 4 and Appendix C) are

responsible for taking data in an HTML order-entry

form and applying the business logic used to query or

update SweetHomes database For Example in the

appointment set up page makeAppServlet provides

functions that check the customers enter both their

customer and broker Id and also check whether

appointment date is in the past or date is valid eg

February 31 is not a valid date

Since Servlets are written in the highly portable

Java language and follow a standard framework they

22

provide a means to create sophisticated server

extensions in a server and operating system

independent way Typical uses for HTTP Servlets

include

bull Processing andor storing data submitted by an

HTML form

bull Providing dynamic content eg returning the

results of a database query to the client

bull Managing state information on top of the

stateless HTTP eg for an online shopping

cart system which manages shopping carts for

many concurrent customers and maps every

request to the right customer

Servlets provide a component-based platform-

independent method for building web-based applications

without the performance limitations of other programs

And unlike proprietary server extension mechanisms

Servlets are server and platform independent This

leaves you free to adopt a best of breed strategy for

your serversbull platforms and tools

23

34 JavaBean

A JavaBean is a reusable component Beans are a

platform-neutral architecture for the Java application

environment Its the ideal choice for developing or

assembling network-aware solutions for different

hardware and operating system environments--within the

enterprise or across the Internet In fact its the

only component architecture you should consider if

youre developing for the Java platform

The JavaBean component architecture extends Write

Once Run Anywhere capability to reusable component

development In fact the JavaBean architecture takes

interoperability a major step forward--your code runs

on every OS and also within any application

environment A beans developer secures a future in the

emerging network software market without losing

customers that use proprietary platforms because

JavaBeans components interoperate with ActiveX

JavaBeans architecture connects via bridges into other

component models such as ActiveX Software components

that use JavaBeans APIs are thus portable to containers

24

including Internet Explorer Visual Basic Microsoft

Word Lotus Notes and others

In this project I write accessBean Propertylnfo

and Brokerlnfo (See Figure 15 and Appendix C) as a

reusable component for SweetHome system For example

every time the psQuery servlet or makeappServlet want

to connect to the database they can just reuse

accessBean instead of writing a new one

JavaBeans is a complete component model It

supports the standard component architecture features

of properties events methods and persistence In

addition JavaBeans provides support for introspection

(to allow automatic analysis of a JavaBeans component)

and customization (to make it easy to configure a

JavaBeans component)

CHAPTER SEVEN

FUTURE DIRECTIONS

The future directions for the SweetHome website

are as follows

1 Use J2EE to develop higher security and more

reliability on EJB reusable component

2 Add more functions to the SweetHome website

such as adding a little calendar on the

Appointment set up page or sending a

notification e-mail when customers make an

appointment successfully and so on

3 Use a more powerful database such as Oracle

9i

4 Purchase firewall software to protect the

system

To apply SweetHome in the real world it needs a

well organized team and enough expense This team

should include real estate experts web designers

database administrators and professional programmers

It also needs to improve performance and security by

purchasing a domain name advanced firewall software

and reliable server hardware
