Ajuda em Chat

IDE : NetBeans 6.5.1

O problema é o seguinte, crio o servidor, os varios utilizadores ligam-se ao servidor ocupando a mesma sala, mas depois quando quero comunicar em privado (um utilizador a falar com outro em privado) nao funciona, a janela da conversacao abre-se, consigo enviar o texto, mas o outro nao recebe a mensagem :
alguem me pode ajudar?

Podiam-me tambem dizer como substituo strings (ex: “:)” por uma imagem com um sorriso?

Obrigado

Não cheguei a olhar o teu fonte, mas só queria lhe mostrar uma outra opção de ferramenta:
http://www.adobe.com/devnet/flex/tourdeflex/web/# na árvore da esquerda vá em Flex Data Access > Messaging Service > Chat.
Com Flex + BlazeDS + Java, vc terá uma interface RIA e pelo q vi terá muito menos código para fazer o q precisa.
