How can I get network user name in java?

Question

I need get a network user name, but I don't know how!

I try "System.getenv("USERNAME")",

"System.getProperty("user.name")" and

"new com.sun.security.auth.module.NTSystem().getName()",

but didn't work, they get local user name, on server they get "server806" and may network user name is "pc8695".

How can I get client user name on client pc??

How would you do it without Java? That is, is there a command-line utility in Windows that will return the info you want? Or, with JNA, even invoking an API might be fairly easy. — erickson, Mar 02 '16 at 16:20
What exactly is a network user name? Are you talking about a specific network service? Your attempts should only give you the windows user... — f1sh, Mar 02 '16 at 16:20
@user3061516 logged on where? in windows? That can be done using ``user.name``. Or in some other software? — f1sh, Mar 02 '16 at 16:29
on windows. System.getenv("USERNAME") don't work on server, this get username from server. — user3061516, Mar 02 '16 at 16:44

Display all environment variables (name : value ) this way

 Map<String, String> env = System.getenv();
    for (String envName : env.keySet()) {
        System.out.format("%s=%s%n",
                          envName,
                          env.get(envName));
    }

Then see what key exactly you need.
