Thank you all for the answers , helped a lot

Ive implemented a thread pool and we are handling about 2000 connection at the moment

Thanks again

Thank you

So the maximum connection would be 10K at any given moment?

If the connection is short lived 1 second would a thread pool work better or just opening the thread and closing?

The
gps pcb would only send a lat and long string that would connect to the server and server would store it in the MySQL database.

Thank you

if (degrees_C){ a if statement should hold a true or false value as degrees_C is a double value is should be compare to something to make it a true or false statement example degrees_C == 10.5

What error are you getting?

Go to the tutorials section here , a lot to learn , start with the basics and slowly build from there.

There is a lot of online help just search in Google for java for beginners

Hope this helps
