should be enough to get you any JVM parameter value.
Note: we do not have JVM parameter in VCS either, but in a database, read by our own launchers in productions. That way, we can change those values remotely, without having to redeploy JVM parameter file settings.
You will find a good sumary of various JVM tools to use in this article (from the "Dustin's Software Development Cogitations and Speculations"), including Java Application Launcher links to :
This technique takes advantage of Platform MXBeans available since J2SE 5 (custom MXBeans support was added in Java SE 6).
Two useful sources of information on the JVM parameters available when using Sun's JVM are:
Both of these resources list and describe some/all of the not-recommended-for-the-casual-developer double X arguments (-XX) that are available.
