Java Platform Debugger Architecture

The Java Platform Debugger Architecture (JPDA) is a collection of APIs to debug Java code.

  • Java Debugger Interface (JDI) – defines a high-level Java language interface that developers can easily use to write remote debugger application tools.
  • Java Virtual Machine Tools Interface (JVMTI) – a native interface that helps to inspect the state and to control the execution of applications running in the Java Virtual Machine (JVM).
  • Java Virtual Machine Debug Interface (JVMDI) – JVMDI was deprecated in J2SE 5.0 in favor of JVM TI, and was removed in Java SE 6.
  • Java Debug Wire Protocol (JDWP) – defines communication between debuggee (a Java application) and debugger processes.
