Technical Articles

• The Mobility Track at the 2004 JavaOne Conference
  Learn more about the 2004 JavaOne Conference technical, business, and BOF Mobility sessions.
• What's New in the J2ME Wireless Toolkit 2.2
  The J2ME Wireless Toolkit is an award-winning, de facto standard development toolkit for J2ME applications. This article describes the latest release, which adds support for Mobile 3D Graphics API, WMA 2.0, the Bluetooth APIs, and PDA Optional Packages.
• FAQ Updated
  The Mobility FAQ has been updated with an item discussing MIDlet launching in MIDP 1.0 and 2.0 environments. The source code for a sample MIDlet suite is also available.
• Interaction Modes in MIDP 2.0
  MIDP 2.0 introduces three user interaction modes in the javax.micoredition.lcdui package. Custom UI items can discover the interaction modes available in an implementation at runtime. Learn how to identify and dynamically adapt to interaction modes in your javax.microedition.lcdui.CustomItem components.
• HTTP POST Basics
  A presentation of the benefits and usage model of the HTTP POST method. The POST method is explained and compared to the HTTP GET method. Code samples illustrate the usage of each method in the MIDP environment.
• MIDP Terminal Emulation, Part 3: Custom Fonts for MIDP
  Third in the terminal emulation series where we add some polish, and some badly-needed control over the terminal emulator's appearance, by taking advantage of MIDP's capabilities for rendering custom fonts.
• Migrating Wireless Applications to MIDP 2.0, WMA, and MMA
  This narrated presentation provides a technical overview of recent updates to the J2ME Platform including MIDP 2.0, MMA, and WMA, which are part of the JTWI specification. Learn how the J2ME Wireless Toolkit and Sun Java Studio help you take advantage of next generation J2ME features.
• Invoking Platform Services in MIDP 2.0
  Learn how to use the MIDP 2.0 javax.microedition.midlet.MIDlet.platformRequest method to access features outside of the J2ME run-time environment. The J2ME Wireless Toolkit supports the platformRequest method and can be configured to invoke a user-specified service.
• Retrieving MIDlet Attributes
  This tech tip describes how to use attributes with a MIDlet suite to add flexibility and reduce test time by separating configuration data from the Java source code. The tech tip also discusses using attributes in both trusted and untrusted MIDlet suites.
