networking - How to make a java client use a socket to connect to a server not on my computer? -


i know how make socket between server , client if both on computer. don't understand how make socket connection between client on computer, , server running on different network. can't do: new socket("machine name", portnumber); right?

you can create socket hostname or ip address. not work in java applets: typically restricted connect machine web page has been loaded from. similar restriction (java special securitymanager) applies old fashioned , strict application servers.

but stand-alone java programs nothing stopping doing it. if have problems might best tell error message get.
