Sun releases Java toolkit for wireless devices

Santa Clara, CA — (press release excerpt) — Sun Microsystems today announced it is offering an enhanced version of the Java 2 Platform, Micro Edition (J2ME) Wireless Toolkit. Live demonstrations of the toolkit, including the early access Japanese version will be at the JavaOne Conference in Pacifico Yokohama, Yokohama, November 28-30, 2001. The updated toolkit securely integrates with major Java technology Integrated Development Environments (IDEs) and is the first toolkit to deliver a set of enhanced new features that enable the design and implementation of Over-The-Air (OTA) provisioning for mobile devices. OTA provisioning is the wireless delivery of applications and services over a secure network to mobile devices, including mobile handsets and PDAs.

Named this June by as the “Best Java Device Application,” the J2ME Wireless Toolkit will help generate more rich and innovative applications and services for Java technology-enabled devices. This enhanced toolkit will help developers to efficiently and quickly create applications while leveraging the expertise of major Java technology IDEs. The leading Java technology IDE vendor solutions include Sun's Forte for Java, Borland JBuilder MobileSet, and Metrowerks CodeWarrior for Java. Sun's J2ME Wireless Toolkit works with these IDEs to provide an easy-to-use development environment with which developers can write, test and debug applications.

The toolkit also helps operators and handset manufacturers to offer a wider range of applications and services with the flexibility of the Java platform and now, the ability to deliver these offerings OTA.

Key features of the J2ME Wireless Toolkit that enable developers to test the creation and secure delivery of applications to devices in a development environment, include:

  • An emulation environment documentation, and examples — Provides an emulated device on a desktop computer system for easily packaging and testing applications.
  • The Connected Limited Device Configuration (CLDC) and Mobile Information Device Profile (MIDP) reference implementations 1.0.3
  • Enables the testing of the same J2ME applications that run on other CLDC/MIDP compliant mobile phones and entry level PDAs.
  • Secure HTTP — Allows secure network connection for delivery of applications and services from mobile devices to standard HTTPS web servers.
  • Source level debugging — Enables more precise detection of application bugs.
  • The MIDP for Palm OS 1.0 — Provides an optimized Java runtime environment targeted at Palm OS handhelds and a standard set of Application Program Interfaces (APIs). It enables Palm OS users to run nearly all Java technology based applications available for CLDC/MIDP compliant mobile phones and entry-level PDAs.
The J2ME Wireless Toolkit version 1.0.3 is available on the Linux, Solaris, and Windows platforms. The product and additional information on the early access Japanese version are available for free download.
