Java Platform Micro Edition Software Development Kit 3.0 for Mac OS
Java ME Platform SDK is a state-of-the-art toolbox for developing mobile applications. It provides device emulation, a standalone development environment, and a set of utilities for rapid development of Java ME applications.
On Windows, Java ME SDK 3.0 is the successor to the popular Java Wireless Toolkit 2.5.2 and Java Toolkit 1.0 for CDC. It integrates CLDC, CDC and Blu-ray Disc Java (BD-J) technology into one SDK.
The Java ME SDK 3.0 is now available for Windows XP and Vista 32-bit, and for the Mac OS. The Mac OS release brings support for CLDC mobile development to Mac users for the first time.

- In the Applications directory, click the Java ME SDK icon to start the application. Wait a few seconds for the Device Manager to detect the default devices delivered with the SDK.
Java Community Involvement
The Java community projects PhoneME and PhoneMEAdvanced are the core around which Java ME Platform SDK is built. The community can also contribute to examples shipped with the product through the MEApplicationDevelopers project or contribute to features of a Lightweight UI Toolkit.
Key Features
Integration with 3rd party emulators and Windows Mobile devices
The new Java ME Platform SDK architecture allows integration of 3rd party emulators and devices. Java ME Platform SDK comes with Sun's Java runtime environment for Windows Mobile. A user can install this runtime on a Windows Mobile device or a Microsoft device emulator and experience all the on-device features of Java ME Platform SDK.
On-device deployment and on-device debugging
Having an emulator doesn't eliminate the need for testing your application on a real device. The new SDK simplifies this process with seamless deployment to real devices and on-device debugging.
New CLDC HotSpot Virtual Machine
The deprecated KVM has been replaced with the CLDC HotSpot VM. This new implementation is a highly-optimized virtual machine which provides a significant performance advantage over KVM.
Optimized MSA 1.1 Stack with Extensions
Java ME Platform SDK contains an optimized CLDC/MIDP stack. This implementation supports multitasking and is built upon CLDC 1.1 and MIDP 2.1. It also contains the following new JSRs:
- Mobile Sensor API (JSR 256)
- XML API for Java ME (JSR 280)
- Payment API (JSR 229)
A built-in profiler lets you easily profile your CLDC/MIDP applications. The profiler is based on the successful Netbeans profiler used in VisualVM, which is bundled with Java SE 6.
New development environment based on the Netbeans Platform
The Java ME SDK leverages the successful Netbeans platform. It provides a reliable and flexible windowing system, a logging facility, and a modularized environment with the ability to update on the fly. A shared project system allows easy transition of your project to the rich, full-featured CLDC/MIDP development tool Netbeans Mobility Pack.
Device search database integrated in SDK
Find technical specifications of thousands of mobile devices using the built-in WURFL database search engine. The database search tool is versatile and easy to use, allowing you to search a large number of mobile device properties. More than 8000 device specifications are accessible from the Java ME Platform SDK.
The SDK includes the JavaFX Runtime and two default phone skins for JavaFX Mobile. The SDK may run a JavaFX application in JAD and JAR form and allows you to profile JavaFX Mobile applications.
