* Java Debug Interface (JDI), a high-level Java programming language interface, including support for remote debugging; 一个高层次的程序语言接口，包括了 支持远程调试 * Java Debug Wire Protocol (JDWP), which defines the format of information and requests transferred between the process being debugged and the debugger front end; JDWP定义了在被调试的过程与调试器前段之中的信息格式与请求转换 * The JVM(TM) Tools Interface, JVM TI. This is a low-level native interface that defines the services a Java virtual machine provides for tools such as debuggers and profilers. JVM TI was introduced in J2SE 5.0 and replaced JVMDI and JVMPI. JVMDI was removed in Java SE 6 and JVMPI will be removed in Java SE 7. JVM TI是一个低层次的底层接口，它定义了java虚拟机所提供的服务，例如调试器和评测器。JVM TI在J2SE 5.0有所介绍，并且代替了JVMDI 和JVMPI。JVMDI 将要在java SE6被取消，JVMPI 在7中会被取消。 上面是在官网上看的，说实话不太了解JPDA 附上网址，希望有帮助http://java.sun.com/javase/technologies/core/toolsapis/jpda/
