vector returns an object after I pass a socket to it?

Im tyring to a very basic threaded client server chat application,

My server app has a Vector to which I add each socket as each client connects.

I want each client to be updated as any one clinet sends a message, I thought the lines below would do it but no it's not happening, any pointers?
for(int i=0;i<vector.size();i++){
        connectToClient = (Socket) vector.elementAt(i);
        DataOutputStream osToClient = new DataOutputStream(connectToClient.getOutputStream());
        osToClient.writeUTF(conversation);
