Question: I am going to start applications development for wireless devices. Could you guide me what I could use for that?

Answer: The production release of the J2ME Wireless Toolkit 2.0 is now available. This version of the toolkit supports the MIDP 2.0 (JSR-118) specification as well as the Wireless Messaging API (JSR-120), and Mobile Media API (JSR-135) optional packages.

The Java 2 Platform Micro Edition, (J2ME) Wireless Toolkit are sets of tools that provide application developers with the emulation environments, documentation and examples needed to develop Java technology applications targeted at CLDC/MIDP compliant mobile phones and entry level PDAs. Two products are available depending on your needs. Both tools are available at no charge to individual applications developers.

For developing applications for MIDP 1.0 devices, use the J2ME Wireless Toolkit version 1.0.4_01.
For developing applications for MIDP 2.0 devices, use the J2ME Wireless Toolkit version 2.0. The 2.0 version also includes built-in support for the Wireless Messaging and Mobile Media APIs.
