ABSTRACT

Chatting, is a method of using technology to bring people and ideas “together” despite of the

geographical barriers. The Chat Server is Communication Software intended for sending and

receiving messages between the members logged in. The Chat server can be configured to listen

at a particular port specified by the system administrator. The Chat clients have to register

themselves with a username and password. The administrator will have privileges to allow or

discard the user registration. Users can also share files among them and also can share their

desktop screens. Thus a project with chatting and file sharing and also desktop sharing provides a

solution to the people to for easy communication and they can share their selves also their ideas

and innovations.

INTRODUCTION

8

Chat server is a standalone application. To start chat you must be connected with the

server after that your message can broadcast to the client though which we want to chat.

Chat system is a complete client/server chat solution, independent chat system (it

does not depend on any product of communication and chat). Chat system

application is a GUI interface. This application makes it easy to find people on a

network and communicate with them easily without being online and makes net

messages easier to read.

On the other hand file sharing application is also implemented where a user can

download a file. We are providing the path to the directory where we have stored our file

to the user who wants to download particular file.

We are also providing desktop sharing features among its registered users; this is a beta

attachment in this chat system and need to improve in future works.

Some features of the application are as follows:

This application is used for sending messages from one client to another client. In

this, server takes a message from the sender client and sends to another client. If

any client wants to join the chatting then he runs the client application on client

side, enters the login name and hits the login button and starts the chatting with

other client.

In this we are maintaining the list of user names (client name) also. After creating

the connection with server, client sends the user name to server and server store it

in the array list and sends this array list to all clients. Same like this when any

client has logged out then server remove this name from the array list and send

this updated array list to every client.

In this application we are providing a file sharing system where a registered user

can view or download files of other user.

Another mile stone feature of this app is that users can share screen among them,

this is provided by java.awt.Robot class.

LITERATURE SURVE

1. According to the survey made on the network used in small scale industries, colleges,

offices and cafes.

2. LAN/WLAN with client-server mode is mostly used network in small scale industries.

3. Here we are implementing it in data transfer with file sharing.

4. The server should be connected for login.

5. The client must have knowledge about networking.

6. The database connectivity of the project should be done properly so data can be

retrieved easily.

7. He/ she must have knowledge about java.

8. The jdk should be installed in the pc on which the project is running.

9. The Wamp server should be in running state.

REQUIREMENT SPECIFICATION

Scope:

LAN chat application is one of easiest way to chat with your friends through

LAN/WLAN or over a AdHoc network. No internet connection is needed. The only thing

which requires is server IP address and you will be able to connect to others members

through LAN. It can help you to talk to your friends even you both do not have internet

connection as it is based on LAN. It connects different client to each other and also client

to main server. So we have used the same concept here we are connecting two client or

client and server with each other and providing the IP address we can talk with each

other.

On the other hand file sharing application is also implemented where a user can upload a

file or download a file. We are providing the path to the directory where we have stored

our file to the user who wants to download particular file.

Technologies to be used

Language used:- JAVA

Java is a programming language originally developed by James Gosling et

al at Sun Microsystems (which has since merged into Oracle Corporation) and

released in 1995 as a core component of Sun Microsystems' Java platform.

Java is a general-purpose, concurrent, class-based, object-oriented language

that is specifically designed to have as few implementation dependencies as

possible.

Operating system used:-Windows XP

Windows XP is an operating system produced by Microsoft for use on personal

computers, including home and business desktops, laptops and media centers. First

released to computer manufacturers on August 24, 2001, it is the second most

popular version of Windows, based on installed user base.

11

Database used: - My Sql

MySQL is a open source database system. This is the easier to implement and

most used database over the world. As a database, it is a software product.

Whose primary function is to store and retrieve data as requested.

The project basically is divided into two sections: - Server and Client.

The server has the full control of the information.

Client who can chat with another client for any reason or can search any file he wants.

The chat part basically deals with message sending and receiving between one client

to another client. When a client requests for the chat, server starts the session of chat

and both can send and receive the message one at a time

The server can store files, search, delete them. The information is stored in the

database at server. When client requests for it, the server searches the required from

the database and replies back to the client.

The system is basically divided into two broad sections:-

Server: - It is responsible for hosting the server so that client can start

communication session.

Client: - Client connects to the server by giving the server IP address and

port number to which it should connect to.

Functional Partition

In this there are two modules one is Client window and another one is Server window.

Client side is used to give the IP address to connect the server. After giving IP address we

must gave the user name and password to login. And then we are chat to another client

and share the file easily.

At Server side the IP address of the client is saved and login time, username and all

information related to client is saved.

E-R Diagram

An ER diagram is a specialized graphic that illustrates the interrelationships between

entities in a database. ER diagram often use symbols to represent three different types of

information. Boxes are commonly used to represents entities. Diamonds is normally used

to represent relationships and ovals are used to represent attributes.

CONCLUSION & FUTURE WORK

The primary goal of this project is to give an idea about Client Server Chat. This

project has given us an in depth information about java networking and its

applications in day today life. If internet lives up to its potential, it will

revolutionize the way people interact with information technology.

Limitations of the application are as follows:

1.) Before running the client application makes sure the server application is running. If

server is not in running condition then you cannot start the chatting.

2.) Single point of failure, server goes down, the network goes down.

Future work:

1. Includes many client

2. Can be implemented in large network like WAN.

3. Hi-speed multimedia transfer and audio video conferencing support.

4. Control all the computer system (clients) and sub-servers in large network like

INTERNET.
