i`m using servlet technology in a very unusual way and i`m now
searching for a better solution:
there is a server, a embedded device and a user, which logs onto the
server, for access to the embedded device. the server now calls the
embedded device via gsm, to tell the embedded device to connect to the
internet and callback. after that, the data from the embedded device is
transfered to the server and displayed as a html-file. this is now done
via polling the application context, where all online-devices are
stored.
problem now is: i want to figure out a better way, how to get the
server or rather the html file, which is refreshed every 15 seconds, to
see if the device is online now, to know.
is there some way to exchange the data between this servlets?
