Preface

This document, KVM Debug Wire Protocol (KDWP) Specification, defines the debugger interface for Java Virtual Machine implementations that are intended to be compatible with Sun’s K Virtual Machine (KVM). KVM is commonly used as the underlying execution engine for the J2ME CLDC (Java™ 2 Micro Edition, Connected Limited Device Configuration) standard. The KVM Debug Wire Protocol (KDWP) is the protocol that is used for communication between a third party Java debugging environment and the K Virtual Machine.

Who Should Use This Specification

The audience for this document includes:

  1. Device manufacturers who want to port the K Virtual Machine (KVM) or another J2ME CLDC Java Virtual Machine to their device and who want their device to support source-level Java debugging with Integrated Development Environments (IDEs) from third-party vendors.
  2. IDE and tool vendors who wish to implement or port a Debug Agent in order to make their development environment capable of supporting source-level debugging of J2ME CLDC devices and applications.

Version History
