Abstract
Teleconferencing or chatting refers to any kind of communication that
offers a real-time transmission of messages from sender to the
receiver.
Chatting is a method of using technology to bring people and ideas
together despite the geographical barriers.
The technology to provide the chatting facility has been available for
years, but the acceptance is quite recent. Analysis of chatting provides
an overview of the technologies used, available features, functions,
system of the architecture of the application, the structure of database
of an Instant Messaging application: IChat(IC).
The objective of IC application is to facilitate text messaging, group
chatting option, data transfer without size restriction which is
commonly seen in most of the messaging applications.
INTRODUCTION
Chatting Application is a desktop based application.
This client server chat application is based on java swing and
used socket package. its simple and easy and require only core
java knowledge. I have taken this program from internet and
modified a little bit to make it simpler and more elegant.
This application/program is a good example of
using java.io, java.net package to create a chat application. A
beginner of java language, who is familiar with this packages
can able, be beneficiate.
Chatting is a method of using technology to bring people and ideas
“together” despite of the geographical barriers. The technology has
been available for years but the acceptance it was quit recent. Our
project is an example of a multiple client chat server.
It is made up of 2 applications the client application, which runs on
the user’s Pc and server application,which runs on any Pc on the
network. To start chatting client should get connected to server. We
will focus on TCP and UDP socket connections which are a
fundamental part of socket programming.
Keywords: sockets, client-server, Java network programming-socket
functions, Multicasting etc.
MAIN OBJECTIVE
The aim of this project is to express how we can implement a
simple chat application between a server and a client? The
application is a desktop based application and is implemented
using Swing and awt. The project is developed in Java SE
language executed on a single stand-alone java across a
network using loop back address concept.
Application consists of two programs:
➔ Server
➔ Client
Server
The server module of the application waits for the client to
connect to it. Then if connection is granted a client interacts
communicates and connects to the server, it can mutually
communicate with the server. The duty of the server is to let
clients exchange the messages.
Client
The client module is the one that utilizer sends requests to the
server. Utilizer utilizes the client as the means to connect to the
server. Once he establishes the connection, he can
communicate to the connected server.
REQUIREMENTS
➔ External Interface Requirements
User Interface
The user interface required to be developed for the system should be
user friendly and attractive.
There are two sets of Java APIs for graphics programming:
AWT (Abstract Windowing Toolkit) and Swing.
⮚ AWT API was introduced in JDK 1.0. Most of the AWT
components have become obsolete and should be replaced by
newer Swing components.
⮚ Swing API, a much more comprehensive set of graphics libraries
that enhances the AWT, was introduced as part of Java
Foundation Classes (JFC) after the release of JDK 1.1. JFC consists
of Swing, Java2D, Accessibility, Internationalization, and
Pluggable Look-and-Feel Support APIs. JFC was an add-on to JDK
1.1 but has been integrated into core Java since JDK 1.2.
➔ Operational Concepts and Scenarios
Operation of the application based on the inputs given by the user:
When the run button is clicked then the chat form is initialized with a
connection between the host and the client machine.
Note: server must be started at first before a client start.
∙ Contains a rich textbox which send messages from one user to
another
∙ Contains a textbox for messages to be written that is sent across
the network.
∙ Contains a Send button
.∙ When the sent button is clicked, in the background, the text in the
textbox is encoded
∙ sent as a packet over the network to the client machine. Here this
message is decoded and is shown in the rich textbox.
Project Scope
This project can be mainly divided into two modules:
1. Server
2. Client
This project is mainly depended on client/server model. The client
requests the server and server responses by granting the clients
request. The proposed system should provide both of the above
features along with the followed ones:
Server
A server is a computer program that provides services to other
computer programs (and their users) in the same or other
computers. The computer that a server program runs in is also
frequently referred to as a server. That machine may be a dedicated
server or used for other purposes as well. Example Server, Database,
Dedicated, Fileserver, Proxy Server, Web Server. The server is always
waiting for client’s requests. The client come and go down but the
server remains the same.
A server application normally listens to a specific port waiting for
connection requests from a client. When a connection request
arrives, the client and the server establish a dedicated connection
over which they can communicate. During the connection process,
the client is assigned a local port number, and binds a socket to it.
The client talks to the server by writing to the socket and gets
information from the server by reading from it. Similarly, the server
gets a new local port number (it needs a new port number so that it
can continue to listen for connection requests on the original port).
The server also binds a socket to its local port and communicates
with the client by reading from and writing to it. The client and the
server must agree on a protocol that is, they must agree on the
language of the information transferred back and forth through the
socket. Normally, a server runs on a specific computer and has a
socket that is bound to a specific port number. The server just waits,
listening to the socket for a client to make a connection request.
1. THE SERVER SCREEN
Client
On the client site the client knows the hostname of the machine on
which the server is running and the port number on which the server
is listening.
To make a connection request, the client tries to rendezvous with
the server on the server's machine and port. The client also needs to
identify itself to the server so it binds to a local port number that it
will use during this connection. This is usually assigned by the
system.
The model used for this project is the single server –
Single client models.
2. THE CLIENT SCREEN
3. THE CLIENT SERVER SCREEN
Future work
There is always a room for improvements in any software
package, however good and efficient it may be done. But the
most important thing should be flexible to accept further
modification. Right now we are just dealing with text
communication.
In future this software may be extended to include features
such as:
Files transfer: this will enable the user to send files of different
formats to others via the chat application.
Voice chat: this will enhance the application to a higher level
where communication will be possible via voice calling as in
telephone.
Video chat: this will further enhance the feature of calling into
video communication.
Conclusion
I Developed network applications in Java by using sockets,
threads, and Web services.
These software is portable, efficient, and easily maintainable
for large number of clients. Our developed web-based chatting
software is unique in its features and more importantly easily
customizable.
The java.net package provides a powerful and flexible set of
classes for implementing network applications. Typically,
programs running on client machines make requests to
programs on a server Machine. These involve networking
services provided by the transport layer.
The most widely used transport protocols on the Internet are
TCP (Transmission control Protocol) and UDP (User Datagram
Protocol).
TCP is a connection-oriented protocol providing a reliable flow
of data between two computers. On the other hand, UDP is a
simpler message-based connectionless protocol which sends
packets of data known as datagrams from one computer to
another with no guarantees of arrival.
