I'm writing a servlet which will be put on our server.
A client can make a request for this servlet.I would like to retrieve the IP address of the client machine(which could be behind a firewall).What code should be put in the servlet to make this happen.
Thanks in advance

You can make use of the method getRemoteAddr() declared in the
ServletConfig interface,implemented by HttpServletRequest class
This method will return the string equivalent of the client
IP address.The firewall shouldn't be a problem.
Hope this helps,
