The Connected Limited Device Configuration (CLDC) defines the base set of application programming interfaces and a virtual machine for resource-constrained devices like mobile phones, pagers, and mainstream personal digital assistants. When coupled with a profile such as the Mobile Information Device Profile (MIDP), it provides a solid Java platform for developing applications to run on devices with limited memory, processing power, and graphical capabilities.

Sun Java Wireless Toolkit 2.3 Beta
is now available.This version of the toolkit is fully compatible with the Java Technology for the Wireless Industry (JTWI) specification (JSR 185). It also includes support for Wireless Messaging API (WMA) 2.0 (JSR 205), Mobile Media API (MMAPI) 1.1 (JSR 135), PDA Optional Packages (JSR 75), Java APIs for Bluetooth (JSR 82), Mobile 3D Graphics (JSR 184), and J2ME Web Services API (JSR 172).

Each Java technology has an API specification, a reference implementation (RI),
and a technology compatibility kit (TCK) associated to it.
Specification:
- CLDC 1.1 (JSR 139):
CLDC 1.1 is a revised version of the CLDC 1.0 specification, and includes new features such as floating point
and weak reference support, in additional to other enhancements. CLDC 1.1 is backward compatible with CLDC 1.0, and continues to target small and resource-constrained devices with the objective of maintaining a tight footprint.
Reference Implementation:
- CLDC 1.1 RI:
This version of the CLDC reference implementation is based on the CLDC 1.1 specification and is targeted at device
manufacturers who want to port this J2ME configuration to another platform.
Technology Compatibility Kit:
The CLDC TCK can be licensed from Sun to certify a CLDC implementation on a particular platform. For more
information about licensing terms, please contact Sun's
Java Partner Engineering group.
Optimized Implementation:
The CLDC HotSpot Implementation(tm) is a virtual machine that is highly optimized and provides superior
performance compared to KVM. In addition to complying
to the CLDC specification, the CLDC HotSpot Implementation includes patented features that propel faster
application execution as well as more efficient resource management. CLDC HotSpot Implementation is targeted
at devices with 16/32-bit RISC microprocessors/controllers (such as ARM-based processors) with as little
as 192 KB of total available memory for the Java technology stack.
