Source code is licensed under The Code Project Open License (CPOL). This is a class project which I wanted to share with others. For any browser to connect to a web-server, this server needs to have a global IP address so that it is visible on the Internet. Similarly jServer also is a application server and for chat over two different networks (say a campus LAN and DSL at your house), it also need to be run on a computer with a global IP address. To understand this, take the example of any web-server. Many people are confused why chat over different networks is not possible. The project's main purpose was to demonstrate networking concepts and due to deadline limitation it was not completed.Ģ. There was much confusion about two issues regarding the project. Upload upl = new Upload(addr, port, ui.file, ui) On sender side, start a new thread for file upload // Connect to the port specified in reply Reply to sender with IP address and port number Send( new Message( " upload_res", ui.username, dwn.port, msg.sender))

On recipient side, start a new thread for download Unlike messages, files do not go through jServer.

The sender, on receiving positive reply connects to this socket and starts file uploadĪn advantage of this approach is that the clients can chat and transfer files at the same time.

For positive reply, recipient's IP address and port number is sent back.

If request is accepted then the recipient opens a new port.

The recipient side sends its reply in a message of type upload_res.

When a user wants to send a file, first his request is sent via a message of type upload_req. Arriving messages are then displayed on message board along with their senders. JMessenger first connects to the jServer, specified by its IP-address and port number. Find the thread of recipient and forward it to him In SocketServer process the messages based on their type public synchronized void handle( int ID, Message msg) Message msg = (Message) streamIn.readObject() In ServerThread read the incoming message and hand it to SocketServer Once the connection isĮstablished, ServerThread will listen for any messages and hand it over to SocketServer to process. The job of SocketServer is to wait for connections and for each connection start a new thread ServerThread. On startup the SocketServer runs inĪ separate thread. There are two main classes in jServer for handling connections and messages.

Recipient: Username of recipient of the message.

type: This can be set to message, login, newuser, etc.

Message structureĮach message in jMessenger has four fields:

In many cases, if jMessenger cannot find the server then adjust firewall to give it network access.īoth applications are written in Netbeans and you can import source files in Netbeans to view and edit them.

On jMessenger select " History.xml" as history file.

There are five stages involved: Step 1: A simple server that will accept a single client connection and display everything the client says on the screen. This file contains usernames and passwords. Creating a simple Chat Client/Server Solution Here is an example of how to extend a very simple client-server demo program into a fully functioning (but simple) Chat Client/Server package.

On jServer select " data.xml" as database file.

Run the jar files jMessenger.jar and jServer.jar and do the following:

Support for both public and private messages.

Handles multiple users at the same time.

It is entirely based on Java and consists of two parts: jMessenger (client application) and jServer (server application).

In this article I am demonstrating a chat application which can handle multiple users at the same time.
