Java Platform Debugger Architecture

DocumentationContents

The Java Platform Debugger Architecture (JPDA) consists of three interfaces designed for use by debuggers in development environments for desktop systems. The Java Virtual Machine Debugger Interface defines the services a VM must provide for debugging. The Java Debug Wire Protocol defines the format of information and requests transferred between the process being debugged and the debugger front end, which implements the Java Debug Interface. The Java Debug Interface defines information and requests at the user code level.
