Dear group,

In the java executable startup, can I do something like:

-Dresin.home=$RESIN_HOME or
-Dresin.home=%RESIN_HOME%

hence letting resin.home be equal to the value of the other
environment variable RESIN_HOME?

Marc

Great, works, tested it! Isn't life wonderful!

import java.util.*;
public class TestProps
{
    public static void main(String[] args)
    {
        Properties p = System.getProperties();
        p.list(System.out);
    }
}

P:\Magdalena\school\Java\certificatie>java -Dresin.home=%RESIN_HOME%
TestProps
-- listing properties --
....
resin.home=C:\java\resin-3.0.18

Didn't you test it before posing the question?

No....

I was just browsing and searching and found this java properties class
after posing the question. I did search in google before posing the
question though, but I could not find it. I hope you're not going to
flame me now?
