Trace runs the Java language program passed as an argument
and
generates a trace of its execution. Trace is a simple command
line tool that uses the Java Debug Interface (JDI). Programs need
not be compiled for debugging since this information is not
used.
Trace can be invoked as follows:
java Trace options class args
Your classpath must include the Java 2 SDK's lib/tools.jar
file which contains the JDI Library
(see set-up),
the path to the compiled trace class files,
and the path for the application being traced.
Available options are:
-output filename
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

class is the program to trace. args are the arguments to
class.
Source for trace
Full source code for trace is included in the
trace directory of examples.jar.
Source code of these example application is included to provide
concrete
examples for debugger developers. Example code may be used, modified
and redistributed by debugger developers providing they adhere to the
terms in the copyright notice.
Building trace
To completely rebuild the trace classes from the
provided source files in the trace directory,
you need only to compile them. No special
options are required, aside from those which set your classpath to
include the JDI Library in lib/tools.jar.
