NetBeans Integration
All Java ME tools are implemented as NetBeans plugins.

  Device Manager
Java ME SDK now supports multiple device managers. You can switch between different versions of device managers.

LWUIT 1.5 Support
The Resource Editor is available from the Java ME menu to help you design and organize resources for LWUIT applications. For a description of LWUIT 1.5 features, visit the LWUIT download page

  Network Monitor
Integrated with NetBeans profiling tools, the Network Monitor now supports WMA, SIP, Bluetooth and OBEX, SATSA APDU and JCRMI, and server sockets.

CPU Profiler
Now uses standard NetBeans profiling facilities to view snapshots. Profiling of VM classes can also be toggled on or off.

  WURFL Device Database
The database has been updated with more than 1000 new devices.

Update Center
Through update center, you can download latest plug-ins for Java ME SDK.

  Chinese and Japanese Localization
We offer extensive localization for Chinese and Japanese. They are all in one package.

  • Tracing - New tracing functionality now includes CLDC VM events, and monitors events such as exceptions, class loading, garbage collection, and methods invocation.
  • New or updated JSR support - Includes support for JSR 234 (Advanced Multimedia Supplements), JSR 253 (Mobile Telephony API), JSR 257 (Contactless Communication API), JSR 258 (Mobile User Interface Customization API), and JSR 293 (XML API for Java ME).

New CLDC HotSpot Virtual Machine
The deprecated KVM has been replaced with the CLDC HotSpot Virtual Machine. 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 on 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)
Profiling support
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 Platform 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 both 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.
