Olá pessoal
Estou implementando um sistema de chat p2p hibrido.
Servidor mantem uma lista de clientes conectados.
Cliente recebe a lista de usuários do servidor e fica abrindo janelas para cada chat.
mantenho a lista dentro de uma jList dentro da classe Contatos que extende jFrame.
A ideia era ter uma Thread que ficaria escutando na porta 6689 as mensagens e com isso encaminhar para a os objetos da classe Chat correspondente ao usuario que enviou a mensagem.
Porem quando dou run() na thread a tela da classe contatos trava e não dá para fazer mais nada.
Se alguem puder ajudar agradeço pretendo deixar o codigo aqui depois para uso e consulta
