Hi,

Use this in Unix.
Runtime.getRuntime().exec("/bin/env").getInputStream());

Or use the set command in order to get the Environment variable in Windows.

Also you can use in java.util.Properties.
For eg in order to get the System Property foo.

String env = System.getProperty("foo");

I hope this will help you.

Thanks

Environment variables are defined per-shell. And the JVM reads the existing values on startup and doesn't dynamically update them if they change. Could either of these traits relate to your problem?

Yes.But it lists all env variables.It is hard to get one of them values.
