Java ME News
The largest area of growth for Java is with mobile devices. A lot is happening in this area, and a lot is going take place at JavaOne next week regarding Java ME.
Java ME Overview
For a quick of review of exactly what Java ME consists of, click here. Read on for a list of some exciting news in the world of Java ME.
Java Device Test Suite (JDTS)
Planning to support Java ME on a mobile phone, set-top box, or other embedded device? You'd better checkout the Java Device Test Suite . The Java Device Test Suite (JDTS) simplifies quality assurance and reduces time-to-market for implementations of the Java 2 Platform, Micro Edition (J2ME), by providing comprehensive tests and a robust test manager to evaluate, validate, and verify the quality of implementations of the Connected Limited Device Configuration (CLDC) and the Mobile Information Device Profile (MIDP) on a particular device.
Java ME at JavaOne 2006
Java developers are powering the mobile explosion, fueled by a thirst for what's new and cutting-edge. From cell phones and smart cards to set-top boxes and printers, tomorrow's mobile applications are in your hands. Attend JavaOne and see the latest tools and techniques for developing and deploying mobile content, including the Java Platform, Micro Edition (Java ME) and Java Card platforms, Blu-ray and, the Java TV API, and more.
Check out the JavaOne 2006 Java ME Session Highlights. Also, get a preview of what Allen Lau of Tira Wireless has planned for the show.
Information Module Profile (IMP)
Hundreds of millions of mobile devices now support the Mobile Information Device Profile (MIDP), the most popular profile in the Micro Edition of the Java platform (Java ME), which requires a UI display, and a simple keyboard. However, there are devices that have only a very simple user interface, or none at all: vending machines, alarm systems, routers, elevators, automobile engines, industrial utility meters, and others. To address these devices, a separate profile has been developed within the Java Community Process through JSR 195, the Information Module Profile . Read more about IMP here.
Java Card 2.2.2 Specification Available
The latest version of the Java Card Platform Specification is available for download. Version 2.2.2 of the Java Card Specification introduces several optional additions to the Java Card platform. These new features provide specific support for the latest contactless and ID cards. Java Card 2.2.2 also includes enhancements to align with future smart card and USIM card standards. Key benefits of Java Card 2.2.2 include improved interoperability for cards with multiple communication interfaces, richer cryptography and security features, and standardized biometry support. It also provides a series of new APIs for a more memory-efficient application development. Java Card technology v2.2.2 is ready for the next generation of smart card standards, and is fully backward-compatible with previous versions.
Java on Television Set-top boxes
The OpenCable Application Platform (OCAP) is the middleware software specification for digital set top boxes and televisions. All major US cable operators commit to deploy OCAP set-top boxes, based on Java ME technology, in 2006. You can view the OCAP specification here.

What are Sun SPOTS?
Project Sun SPOT is an innovative, battery-operated platform, created in Sun labs to enable development of wireless sensor networks, robotics and personal consumer electronics. Powered by a small Java 2 Platform, Micro Edition (Java ME) virtual machine written almost entirely in Java, Project Sun SPOT provides a way to easily, affordably and quickly build Java-based sensor applications that run directly on the central processing unit (CPU) without any underlying operating system.
To see these innovative, and cool, devices in action, check out the site that Sun has created just for Sun SPOTs.
