Hi there,

When working with a multi-threaded application that involves the use of the
ServerSocket class; the ServerSocket class takes an integer as an arguement
for a Port Number.
i.e. ServerSocket socket = new ServerSocket(2500);

Let's assume this port is already being used by another thread. Is there
some way to check if the port is already active so that we can allocate a
different port number or at least continue to check the port until it
becomes free?  I'm thinking maybe using a queue for the port or simply
providing a different port if one is already being used. How does one
generally tackle this problem? How does one query a port?

Alan
