You can use the System.getProperties method. Of course it will only get Java and general stuff. Anything TOO related to the operating system is not available in this.

I think you can see your environment variables using java.util.Properties. I am not sure, but I think you can.

Hi,
U can also do it indirectly by using Runtime.exec. You can execute the cmd.exe (in NT) or command.com (Win 9x). You can capture the output of DOS command env using a Reader and then extract the info. from that.
