JavaTM Platform Debugger Architecture
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 Tools Interface (JVMTI) defines the services a VM must provide for debugging (JVMTI is a replacement for the Java Virtual Machine Debug Interface (JVMDI) which has been deprecated). The Java Debug Wire Protocol (JDWP) defines the format of information and requests transferred between the process being debugged and the debugger front end, which implements the Java Debug Interface (JDI). The Java Debug Interface defines information and requests at the user code level.Enhancements
NOTE: JVMPI, the experimental Java Virtual Machine Profiling Interface has been deprecated and will be removed in the next major release. It has been replaced by JVMTI.
NOTE: JVMDI has been deprecated and will be removed in the next major release. It has been replaced by JVMTI.
The demo/jpda/examples.jar file in the JDK software contains JPDA examples, including source code for the jdb Java Debugger and the prototype javadt GUI debugger.
