asked on
Computer (host) name in Java (JSP page)
Hi everyone,
I want to retrieve a computer (host) name of the machine in Java on WinNT based intranet. The Java code is implemented in class, which works on JRun application server JSP (server-side).
To make myself clear I want to get the computer (host) name of the client machine, that made the request, in class, implemented in JSP page, that works in application server. (hmmm, what a sentance...). I don't want to store the IP addresses of the clients, becasuse they are dynamic.
Hope I expressed my self clear.
Thanks in advance.

TimYates, this does not work. It returns the same as request.getRemoteAddr() - i.e. the IP address.
try
following code
<%
try
{
String hName = InetAddress.getByName(requ
}
catch(Exception dd)
{
dd.printStackTrace();
}
%>

rjackman, I get the same result as request.getHostName().
There is something that I forgot to mention, there is firewall in the intranet, so all requests to application server appear to come from the firewalls IP address.
The firewall is on a different network (I can ping it, but I can not access it using the hostname).
I wonder is it possible to get the computer name in this case?

Probably not... :-(
It should be possible by using either signmed applet or signed javascript.

Unfortunately I can not use signed applet, and javascript is not working for me. I need the host name on server side before page is sent to client.
