One way you could implement this, if you have complete control over how
your program is called, is just to pass the arguments to the JVM as
parameters to your program, so you can supply them later to the OS.
java -Djava.lib.etc=x -cp Hi Test -a -b -JARG Djava.lib.etc=x -JARG
cp -JARG Hi
So you strip off or ignore the JARG parameters when your program runs.
Before you re-execute, you add them back to the exec() string.
Runtime.getRuntime().exec( "java " + $JARGS + $Prog + $Parms + $JARGS );
Well that's ugly, but I hope you get the idea. You can pass in the
arguments in two places, where they need to go for the JVM, and also
where your program can see them and pick them up. A bit of string
manipulation will be needed to mung them to the exact format (not shown
here).
This only works if you have complete control over how your program is
called. If random folks or other processes are executing your program,
you might not be able to guarantee they always place parameters in two
places as required.
My goal here is to avoid shells and provide a 100% Java, 100% portable
solution. What's better ... shells or Java... is up to you. Good luck!
