<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML//EN"> <html> <head> <title>Example JDI Applications</title> </head> <BODY BGCOLOR="#FFFFFF"> <h1>Example JDI Applications</h1> This example download contains the source code and documentation for three applications written using the Java<sup><font size=-2>TM</font></sup> Debug Interface (JDI) of the <A HREF="http://java.sun.com/products/jpda">Java Platform Debugger Architecture</A> (JPDA). They are provided as educational tools and as starting points for debugger development. <P> In increasing order of complexity: <UL> <LI><A HREF="trace.html">Trace</A> displays traces of program execution. It is very simple (less than 600 lines) yet uses most of the basic JDI functionality. It is a good starting point. <LI><A HREF="jdb.html">Jdb</A> is the command line debugger distributed with the J2SE SDK. <LI><A HREF="javadt.html">Javadt</A> is the beginnings of a GUI debugger. </UL> <P> Trace is in the <code>trace</code> directory. Jdb and Javadt share a package, and are under the <code>debug</code> directory. <A NAME="SETUP"><H2>Required Set-up</H2></A> <H4>Where is JPDA?</H4> New versions of the J2SE SDK have JPDA included. For older versions JPDA must be separately downloaded. <DL> <DT>SDKs with JPDA included <DD>J2SE SDK v1.3 and later and J2SE SDK for Linux v1.2.2 <DT>SDKs requiring JPDA download <DD>J2SE SDK v1.2.1 and v1.2.2 for Solaris and Windows <DT>Other SDKs <DD>Check with vendor </DL> <P> <H4>Set-up for J2SE SDKs with JPDA included</H4> Your classpath must include the JDI Library code, which is in <code>tools.jar</code> in the <code>lib</code> directory. This is needed for both compiling the example code and executing it. <p> <H4>Set-up for J2SE SDKs without JPDA - Solaris</H4> Download JPDA v1.0 from <A HREF="http://java.sun.com/products/jpda">http://java.sun.com/products/jpda</A>. Follow the <A HREF="http://java.sun.com/products/jpda/installinst.html">Installation Instructions</A> found there. Pay particular attention to setting the library path. <P> Your classpath must include the JDI Library code, which is in <VAR>jpda_home</VAR>/<code>lib/tools.jar</code>. This is needed for both compiling the example code and executing it. <P> <H4>Set-up for J2SE SDKs without JPDA - Windows</H4> Download JPDA v1.0 from <A HREF="http://java.sun.com/products/jpda">http://java.sun.com/products/jpda</A>. Follow the <A HREF="http://java.sun.com/products/jpda/installinst.html">Installation Instructions</A> found there. Be sure to add: <PRE> <VAR>jpda_home</VAR>\bin </PRE> to your path. <P> Your classpath must include the JDI Library code, which is in <VAR>jpda_home</VAR>\<code>lib\tools.jar</code>.
