<B>Trace</B> runs the Java language program passed as an argument and
generates a trace of its execution. <B>Trace</B> is a simple command
line tool that uses the
<A HREF="http://java.sun.com/j2se/1.4/docs/guide/jpda/architecture.html#jdi">

<B>Trace</B> can be invoked as follows:
<PRE>
java com.sun.tools.example.trace.Trace <i>options class args</i>
</PRE>
Your classpath must include the JDI Library
(see <A HREF="index.html#SETUP">set-up</A>),
the path to the compiled <b>trace</b> class files,
and the path for the application being traced.
<P>
Available <i>options</i> are:
<PRE>
-output <i>filename</i>
Set destination for output trace. By default output
goes to the terminal.
-all
Include system classes in output. By default
java.*, javax.*, sun.* and com.sun.* events are
not diplayed.
-fields
Also show assignments into fields.
-help
Print a help message
