Need your expert help on my small client/server app

I'm a little bit stuck, I'm able to send messages from multiple clients to the server. But the server should send back the message to ALL connected clients, I can't seem to get this part working. It only sends the message back to the client that originally sent the message..

I've attached the Server.java and Client.java - I hope you can help me guys

I run them like this, in different command prompts

java Server
java Client localhost

Or alternatively I have also put my code online here;
