Hi Stephen,
JDK 1.3 introduces a new version of jdb (based on JPDA) with a new
command-line interface that the JDE does not understand. I do not intend to
update the JDE to support the new jdb, at least not anytime soon, because
the JDE includes its own JPDA-based debugger, called JDEbug, that is far
superior to jdb in functionality. I suggest that you use JDEbug. If you
want to use jdb, use the old version. It is included in the JDK 1.3 bin
directory under the name oldjdb.
