I am writing an install program for some software that I developped, but I now realise I need to include some environment variables in my install process for it to work. How is this done, do I set the install program to get the user to state the were these variables are to be located or....what???

Tell me if this is what you are expecting. This example reads the PATH environment
variable of a Windows machine:

- command line: java -DPATH="%PATH%" Environment

- code:

public class Environment {

    public static void main(String args[]) {
        String path = System.getProperty("PATH");
        System.out.println(path);
        return;
    }
}
