FTP/Networking

thats to bad you may learn something
here is the
data on port 8080 IANA registration
nothing to do with java protocal unless you want it to
http-alt 8080/tcp HTTP Alternate (see port 80)
http-alt 8080/udp HTTP Alternate (see port 80)

that's true for all port usage.
one can config FTP to use port 80 and a web server to use port 21.

let's just agree to disagree. if need be, I concede you're right and let's get back
to solving real problems.
