We have a piece of Java coursework due in on friday and haven't a clue where to start.

Basically we need to design a Client-Server system that allows Stock Tickers to be displayed to multiple clients.

Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.

the system should have the following functions:
-User can log in, watch list is retrieved and displayed
-Ticker is updated when a stock price changes
-User can add/remove a stock to/from their watch list
-Administrator can add/remove a user
-Administrator can add/remove a stock
-Administrator can view price history of a stock

we've also been told:
-it should only use standard classes from the java SDK
-We may use either sockets or RMI for this system(they're all we're supposed to know about so nothing to advanced please)
-For persistent storage we should use the Java serialisation mechanism and not a database
-There will be a "real time price feed from a number of stock makets" simulated by a file of prepared test data. this will be a sequence of(stock symbol, new price, time interval) triples.
you wil ned to write a class that reads and processes this file, delaying for each time interval and then making the appropriate price change.

information about a user includes user name, password, email address.

information about a stock includes symbol(unique id), stock name, company name, price history data(a sequence of prices and dates/times when the price changed.

We want Complete ownership and distribution copyrights to all work purchased.

Hope this is enough information to get started with.

it will be tested on a university machine so a windows environment should do the job fine.

Must be 100% finished and received by buyer on:
Mar 26, 2003 EDT

I just checked your specifications. everything is clear and comprehensive.

there will be a command line running server which will display in command line all operations performed by clients, I don't think a GUI will be necessary for the server but I can implement one if you wish.

about the client ... that will be a nice application with an intuitive well-designed GUI which will cover all your requirements.

I'm almost sure you want the code as simple as possible that's why I think I should not use RMI but sockets and serialisation, but again if you want RMI ... no problem.

these were the basic lines of the development.
theoretically should be done in less then 2 days.

also, everything will be as simple as possible and very well commented.

I am online 24/7 so if you'll have any questions ... just ask :D

I think I already wrote enough blabla but just to make sure you will get an A+ job, check my ratings : I was rated only 10 and I am coder #9 out of about 39000 coders.

any questions ?

just flashed through my brain : the client will also be able to be used an applet so it could be inserted in a web-page.
