Create a TCP socket based Inventory server that supports calculating the
tax on a PO. This remote server should be called:
it should implement the following function: sent a double it should multiply
it by .0825 and return a double via a TCP socket
Your existing application should have a button added to the UI that adds up
the cost of all books selected, calls this service via TCP and gets the result
and displays the tax due on the books. It should add that with the subtotal and
display the total. It should save these in the PO file also.
No error checking is required. Just a simple TCP initiator and TCP acceptor
set of applications.
