Wrap up

What we covered

In this tutorial, we have covered almost every aspect of J2ME by developing a typical application -- UniStocks.

You received great hands-on experience in MIDLet basics, high-level user interface design, low-level user interface design, persistent storage mechanisms, J2ME networking, and server-side design, among other areas. In addition, I presented various frameworks and techniques that you can use to develop your own J2ME applications with ease and confidence.

Source/binary code configuration

  1. Download pj2me.zip from http://www.jackwind.net/resources/pj2me.
  2. Unzip pj2me.zip to a directory. Read carefully the license in license.txt. The UniStocks folder contains the MIDlet client source code and resources; the jackwind folder contains server-side code (the servlet).
  3. Run UniStocks. Copy the UniStocks folder to WTK's apps directory, and UniStocks should appear in your project list of WTK ('Open Project ...'). Open UniStocks and run it. The default stock provider is http://www.jackwind.net/resources/pj2me/StockInfoProvider.php, so you should configure the proxy setting before connecting to our server.
  4. Set up your own stock provider (optional). First configure your proxy host and proxy port in file StockInfoProvider.java (inside the jackwind folder). Compile source file and install the servlet. For details, please refer to README.txt under jackwind/WEB-INF. Set the UniStocks JAD file's user-defined attribute INFO_PROVIDER_URL to your servlet URL; for example: http://127.0.0.1:8080/jackwind/servlet/StockInfoProvider
