Hello!
Did you try taking input stream from process?

"Something like" doesn't help anyone debug your real code.

Try using Properties.load(InputStream), passing the p.getInputStream()
as the argument.

If that doesn't work, post a complete example.

if you run on java 1.5,
you needn't use Process class,
toy can use System.getEnvs() method,
which return you a map of all environnement settings
