Getting client environment variable value from java

Question

I have a web project, and I try to get the environment variable value from the client by Java. I use

System.getenv("computername");

but it always return the computername of server, so how can I get the environment variable value from client in java or javascript ?

you can't using java .you should use client language like `javascript` .but i think it's impossible .read http://stackoverflow.com/questions/922476/how-can-i-read-the-clients-machine-computer-name-from-the-browser — Madhawa Priyashantha, Jul 13 '15 at 04:35
you need to do that in your javascript, i hope java runs on your server while javascript runs on your browser — kuhajeyan, Jul 13 '15 at 04:35
I think you are getting server side and client side development mixed up. _Where_ do you need to use the client side computer name? — Tim Biegeleisen, Jul 13 '15 at 04:35
yes, I think I should use it in javascript, but I cannot find any solution for it :( — user3040408, Jul 13 '15 at 04:37
@user3040408 because it's impossible.read the question i have linked there is answers but only work for ie — Madhawa Priyashantha, Jul 13 '15 at 04:37
For security reasons you can not do it even using Javascript. if you asked the user to fill in the field then you could pass it as a parameter. — Scary Wombat, Jul 13 '15 at 04:38
thanks for all answer :D, so could I get the computer name from client's IP Address ? — user3040408, Jul 13 '15 at 04:43
this no problem @FastSnail because I will get IP Address when login and then get Env value and keep it in session :D — user3040408, Jul 13 '15 at 04:52

I think its possible if you use applets on client side.Am not sure javascript on client side can provide environment info.
