  1. Please plug in your laptops and pair up. WelikeGWT! …we think you will too. Stuart Ervine & Franck Rasolo

  2. Introduction • In this workshop we'll be building a short application. • Please figure out how to boot your laptop from either the CD or USB. • If you can't boot from either please pair up with someone who can.

  3. What is GWT? • Java toolkit for building rich web applications. • You can write all the code in Java, so no JSPs, templating languages or action classes. • It compiles into Javascript, uses asynchronous requests. • It is more akin to Swing.

  4. What we're not going to cover here. • No GWTTestCase • No Google API integration • No 3rd party GWT library integration • No optimization (though feel free to talk to us about this after) • No JSNI • No CSS crap • No clever ruby / python back end integration • No discussion on client architecture • Little, if any, comparison with or discussion about other (Java) web frameworks

  5. A short tutorial. • Explanation of the background & requirements for the sample application.

  6. Code the first task The tasks. • User needs to see current holdings & profit through sales of his client. User needs to be able to sell stock.

  7. Opening the example application. • Boot from the USB drive (BOOT mount) or CD provided. • Open the APPS mounted drive, and run ./start.sh. • IntelliJ should open and you can run the sample application by clicking...

  8. The deep end. • User needs a way to refresh the stock prices. • If a stock is above 5%, advise user to sell stock. • If a stock is between 5% and -5% advise user they might want to wait and see. • Trader wants to be able to set a profit alert on a stock. • If the stock goes above the profit, he wants sell advice. The profit should default to 5%. • The trader wants to be able to set a loss alert on a stock. • If the stock goes below the profit, he wants dump advice.
