Well, start by using mixed case--you look like you're shouting. And "I want"
is no way to start a request for help. Try asking for help or asking a
question or something more polite than a demand to those who ask nothing in
return for helping you. See

Googling for "get client ip" java appet yielded

http://forum.java.sun.com/thread.jspa?threadID=367855&messageID=1556409

clientIP=InetAddress.getLocalHost().getHostAddress();

-OR-

String hostname = InetAddress.getLocalHost().getHostName();
System.out.println(hostname);
InetAddress[] ads = InetAddress.getAllByName(hostname);
for (int i=0; i<ads.length; i++) {
System.out.println(ads);

But in both cases you may get just the local host name or a non-public
(private IP) name.

This response
http://forum.java.sun.com/thread.jspa?tstart=105&forumID=421&threadID=358273&trange=15

shows how you can have the applet bounce a request to the serlvet from which
it came and that servlet can get the public-side IP address of the machine.
Note that even in this case you cannot guarantee that you can use this IP
address to make contact with the client or even to uniquely identify the
client. This is because the client's actual (face, public WAN) IP may be
from a private network and NATTed into a shared IP address or otherwise
non-reverse-routed. You may find more details at
