Requesting the location of a running server knowing its machine name and
port number is critical for NetBeans or eclipse when you can register 10
different servers (only 1 being running of course) on the same machine.
This way, we know exactly which one is running and can display the
correct status on these 10 different installations on the same machine
with the same port number. (The location attribute gives us the extra
data for a unique primary key in our internal registry of registered
servers)
Otherwise, we would display 10 runtime nodes in NetBeans as the running
status which would be a bug.
Hope this help,
