Question: What's New in the J2ME Wireless Toolkit 2.0?

Answer: The J2ME Wireless Toolkit contains everything you need to develop MIDP applications.
New Emulator Skins
The J2ME Wireless Toolkit 2.0 includes an entirely new emulator skin, QwertyDevice. Sporting a whopping 640 x 240 pixel color screen and a full keyboard, QwertyDevice represents a wireless communicator, a level beyond a mobile phone.

The Vanguard of MIDP 2.0
The J2ME Wireless Toolkit 2.0 emulator implements the MIDP 2.0 specification, which includes dozens of exciting features, including:

  • Secure networking with HTTPS
  • Support for playing simple tones and sampled audio data
  • The ability to create custom item components for forms
  • A game API
  • Use of int arrays to represent and manipulate images
  • A permission-based security architecture
  • A push registry that enables MIDlets to receive incoming network connections

Check Out the Sound System
One of the new features in MIDP 2.0 is the ability to play sampled audio and simple audio tones. The J2ME Wireless Toolkit 2.0 supports the full Mobile Media API 1.0.

Setting MIDlet Permissions

Working with Protection Domains
A protection domain determines whether a permission is granted or denied.

Signing MIDlet Suites

A Killer Feature: Run via OTA
To test installation behavior, the push registry, and signed MIDlets use new option in the Project menu, Run via OTA.
