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.

  • 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.
