Arquivo Discussoes de Programacao e Tecnologia Ola Amigos do forum estou usando IDE NETBEANS 6.9.1 e necessito debugar esta classe chamada cliente, porem eu tenho alguns metodos e classes que dao erro, como BufferedReader, PrintWriter e Vector…!
O netbeans aponta a classe Vector diz que e obsoleto, e BufferedReader e PrintWriter fala que nao existe.
Bom, estou usando J2ME como projeto!
Vcs teriam alguma solucao basica para isso??
Agradeco!!
Vai um print
Substitui o PrintWriter por DataOutputStream e o BufferedReader por DataInputStream.
o que eu faco com a importacao VECTOR??? sendo que eu preciso dela ???
Amigo, a classe Vector não tem nenhum problema compreendeste?? O pacote util existe desde sempre desde o CLDC 1.0.
Esse warning deve por que você tem um import e não o esta usando de fato na classe… 
Sacou?

Ok, entao quer dizer que o warning que fala que o import e obsoleto e normal............?
Vou postar o codigo aqui:
Tomara que debug a classe depois de fazer as alteracoes....!
To postando o codigo agora, se vc puder dar umas sugestoes eu aceito valew!
Eu vou fazer as mudancas ate de noite, ae te mando uma mensagem!

Com certeza aquela mensagem que tu estavas recebendo pelo NetBeans era porque a classe Vector não estava sendo usada ou talvez estava sendo chamada em um método não estatico enfim algum problema no seu código. A classe Vector não tem nada a ver com Obsoleto das anotações de deprected

Cara, presta atenção ao post que já te respondi!!
Não falei sobre DataOutputStreamWriter mas
PrintWriter por DataOutputStream e o BufferedReader por DataInputStream.

Eu ja alterei o printwriter e o bufferedReader… so que ta dando erro em outras coisas agora…estou tentando descobrir o que e…
Bom, faz o seguinte pegue esse tutorial aqui
http://developers.sun.com/mobility/midp/articles/bluetooth2/
vai te ajudar bastante. Vc deve ter pego um tutorial que use o Bluecove para desktop. Logo, o compilador acusa esses erros porque essas classes não fazem parte da configuração CLDC para j2me. Se ainda não conseguir vou te mandar uma classe para te mostrar 
Este e o link que tem o codigo fonte SPP do cliente e o codigo fonte SPP do servidor:
http://www.jsr82.com/jsr-82-sample-spp-server-and-client/#more-22
O servidor rodou ok…na hora de executar o servidor roda e espera a comunicacao com o cliente !!
O cliente da aqueles erros…cv acha entao que ele e especifico para API Bluecove ??
