JAVA FOR MOBILE DEVICES

Java for Mobile Devices is a set of technologies that let developers deliver applications and services to all types of mobile handsets, ranging from price efficient feature-phones to the latest smartphones. Java is is currently running on over 3 billion phones worldwide, and growing. It offers unrivaled potential for the distribution and monetization of mobile applications.

At the core of the Java Mobile Platform is Java Platform, Micro Edition (Java ME). Java ME provides a robust, flexible environment for applications running on mobile and other embedded devices: mobile phones, TV set-top boxes, e-readers, Blu-Ray readers, printers and more. For over a decade, Oracle has been working along with leading mobile and embedded companies to develop the Java ME Platform through the Java Community Process (JCP). A key achievement has been the definition of the Mobile Services Architecture (MSA), setting a baseline of mobile APIs that developer can target within their applications. In 2011, Oracle and partners will be working within JCP to drive Java ME.next - a proposal for the modernization of Java ME .

In addition to its role within JCP, Oracle is also a provider of high performance Java ME implementations and developer technologies being used to deploy tens of thousands of applications worldwidein the mobile and embedded markets, including:

• Java ME SDK: a state-of-the-art toolbox for developing and testing mobile applications.
• Light Weight UI Toolkit (LWUIT): a compact library for the creation of rich user interfaces.
• Oracle Java ME Embedded: designed and optimized to meet the unique requirements of small, low power devices.

LWUIT 1.5

Light Weight User Interface Toolkit 1.5 is released in Auguest 2011 - both in source and binary form. It comes with new GUI builder, IO Framework, Java SE Support, HTML4 Tag Support, new UI components, ContainerList, and Audio Playback API. Check out Download LWUIT page for more information.
