Submission Summary
System
Submission of files to os-2010sp2/$USERNAME/assign2 using the official CVS server for the OS subjectFiles
Only *.java files required to run the assignment and your evaluation.txt fileMarking
We will be using partially automated marking software, so you must follow these instructions exactly.
Evaluation
You will be required to estimate and justify the grade that you think you deserve for the assignment, based on the marking criteria included. This should be included in the file evaluation.txt in the assign2 directory.
Target platform
The assignment will be marked on cis-lab.ml.unisa.edu.au, make sure your program is able to run on this host.
Specifications
It is very important that you follow the instructions in this document exactly!
The name of the directory you must use in CVS is assign2. Make sure you spell it exactly the same, with the correct case (do not use any upper case letters - Unix is case sensitive!).
Make sure that you test your code on Cis-lab to ensure that it will work for our marking system. Make sure you submit your code early and often.
Your program must be started using the command lines specified later on in this document.
No graphical outputs required. Outputs of both the client and the server are text based.
You must include a text file in plain ASCII called evaluation.txt which contains a written description of what grade you think you deserve, and a justification of why this is so.
Reminder: Please close your client and server once you finish your tests, to free the CPU/memory/port resources for other students. Your process will be killed if you leave them running over 24 hours.
Overview
In this assignment, you will be required to implement client and server programs for a shared white board application. The application requires two components to be implemented, the client and the server. The client allows a user to manually input drawing commands, which is send to the server. The server then takes these messages and sends them to all of the other clients connected to it. The end result is that all clients can see the drawings being entered by the other users, and the server provides the ability to connect them all together.
Program Requirements
You are required to implement a client in Java as a console based application, which is capable of taking inputs from the user and sending them across the network. Messages from the network must be displayed as text on the standard output device. The server must also be implemented in Java, as a simple console based application. You are free to implement your Java code for the client and server in any way that you like, as long as it meets the following guidelines: |
