I'm building a web application (a card game) which needs 4 players to play. I used servlets for server side and knockout js for client side. I'm using tomcat server and I just ran it on localhost when implementing. Now I want to see whether it works by connecting 4 players. How do I do it in a single computer? Are there any tools for this task?
Can't I connect with multiple clients in the same machine? Do I definitely need multiple machines? Can someone please give a tip?
