Look up the java doc for HttpRequest.
You should probably use remadr = request.getRemoteAddress() or something
like that. That will give you the IP of the client, not your own IP.
Then you should use a DNS lookup (I mean the equivalent Java function)
to translate the remote IP into the corresponding remote name.
request.getServerName() probably gives you the name of your own server
(the one which is in the <Host> tag of your server.xml config file.
More precisely :
getRemoteAddr
public java.lang.String getRemoteAddr()
Returns the Internet Protocol (IP) address of the client or last
proxy that sent the request. For HTTP servlets, same as the value of the
CGI variable REMOTE_ADDR.
Returns:
a String containing the IP address of the client that sent the
request
getRemoteHost
public java.lang.String getRemoteHost()
Returns the fully qualified name of the client or the last proxy
that sent the request. If the engine cannot or chooses not to resolve
the hostname (to improve performance), this method returns the
dotted-string form of the IP address. For HTTP servlets, same as the
value of the CGI variable REMOTE_HOST.
Returns:
a String containing the fully qualified name of the client
