Question 2: How to fetch the MAC address (Physical address) of
the clients using web application ?
You can not do this at the server. Some clients may not even have one - a
computer with no network card using a dial-up modem to access the Internet has
no MAC address. If you look at the OSI 7-layer model, the MAC address exists
in some Datalink (layer 2) implementations, but need not exist on all.
If you really, *really* need the MAC address, you would have to write a piece
of code to download to the client computer and run on the client computer to
get it. I suspect most anti-malware programs would recognise that software as
spyware and stop it running.
In other words, you can only get the mac address from the computers in
LAN. Everything that comes outside your LAN does not have mac address.
For computers in the local network you could execute "ping ip", and then
"arp -a", and parse the result. Or you could look for an Java ARP
implementation, there are some of them on the internet, but are not very
simple to use.
