Re: [Jython-users] How can one propagate "System" property toJVM from jython command line ?

[Stuart S. <st...@me...>]

Hi Brian,

    I uncommented the source (org/python/util/jython.java) and recompiled under JDK 1.3,
and the properties now get propagated (it works) using the tweaked jython.jar .
Been a long time since I've been under the hood in a compiler/interpreter (gcc for HPUX-6.5
back in... um, a while ago...;-)

Thank you for both pointing out where the problem was, and reminding me that I can
actually do something about it...

You could optionally change the batch/shell script you use to invoke the jython interpreter to pass the -D arguments to the JVM as opposed to the PVM (the way you are doing it) and then the properties will be available to you.  Hope this helps...
