Objective of Project

The aim of this project Client Server Design SharingSystem is to provide a communication system withinan organization.

This application will be capable of facilitatingmembers of the organization to communicate throughtext as well as graphical designs.

Application has client and server based architecturewhich allows multiple user to interact with each otherindividually and in groups at the same time remotely.

Need of the System

As many of the chat applications are available in themarket today but still may wonder how it has beendeveloped. Thus, this is a simple chat applicationdeveloped in java using a web service.

The application targets mainly the beginners of theorganization who sometimes fear of using the web

service. The members will get a taste of how webservice can be easily developed and can be used in achatting application.

DESCRIPTION


7/28

The project I have worked on is the development of aClient Server Design Shar ing System.

Today java client server application is the primary needof the working personnel specially and other people.

We have tried to provide a user-friendly interface for

providing a complete solution to the Client Server

Design Sharing System.

Characteristics of a client:

Initiates requests.

Waits for replies.

Receives replies.

Supports design sharing.

Typically interacts directly with end-usersusing a graphical user interface.


9/28

Never initiates requests or activities.

Listens to network and responds only to

requests from connected,authorized clients. Waits for and replies to requests from

connected clients.

Characteristics of a server:


10/28

Basic Functionality of the system:

Whenever any user logs into the application, anotification window will get popup in all the onlineuser machines from the right corner of the screen toshow the name of the new online user.

Whenever the user minimizes the chat window, thenew messages will start coming to that user in a

popup window from the right corner of the screen.

If the user wishes not to get the messages in a popupwindow he can select a suitable checkbox.

DESIGN

Design Description

Design of the project basically includes two applicationsnamely

Client Application:Main goal while designing the client is to make it

multi-threaded.

One thread runs the user interface.

A separate thread handles the I/O with the server.


13/28

Server Application:Here also the goal is to make the server multi-threaded.

It handles the user interface with one thread.

A second thread listens on a well-known port for clientconnections.

A third thread is started when a client connection is made tohandle that client's requests.

After launching the thread to handle a client's connection, theserver continues listening for additional client connections. Ifanother connection comes in while an earlier client is being

served, a fourth thread is started to handle the new client'srequests, etc. Thus, the server includes at least three threads

but may start additional threads for multiple simultaneousconnections.

SYSTEM DEVELOPMENT


22/28

TOOL/PLATFORMA program used for software development or system

maintenance. Virtually any program or utility that helps

programmers or users develop applications or maintain

their computers can be called a tool.

Here in our application we are using Textpad (Java).

SOFTWARE REQUIREMENTSJava (JDK 1.3)

Some of the advantages of Java framework are: - Consistent programming model

Multi-platform applications

Multi-language integration

Automatic resource management

Ease of deployment

HARDWARE PLATFORM

The Client Server Design Sharing System will be available to the Userswho are the members of the organization. Therefore the system has twoaspects, namely the client and the server.

The Client:The hardware requirements of the client are as follows:

A Local Area Network Connection

Color Monitor or any other Visual Display Unit

Mouse and Keyboard for User Inputs

The Server:The hardware requirements for the server are as follows:

A minimum of 512 MB of Random Access Memory

Connection to LAN


25/28

SOFTWARE PLATFORM

The Client:The software requirements of theclient are as follows:

Operating System

Web Browser

The Server:The software requirements of theserver are as follows:

The Java Framework
