| <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. |

| <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> |

| 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 |
