Campos, actionPerformed, botão netbeans

Thread.start() Membro desde: 20/07/2011 08:53:26 Mensagens: 44 Offline

Olá galera!

O codigo me apresenta erro nos nomes dos campos text:
(0, jTextNome.getText(), jTextBanda.getText(), jTextAno.getText(), jTextDuracao.getText());

No NetBeans, ele sugere para criar os campos (ou até classes), porém ja tenho esse campos, eles estão com o nome correto.

Valeu pela ajuda!

Eles estão escritos exatamente da mesma forma (com maiúsculas/minúsculas)?
Dá uma conferida se por acaso não estão sendo encontrados por estar num escopo que não está acessível. Ou senão, se de repente eles estão estão declarados na classe principal da tela e vc está tentando acessá-los na classe do ActionListener.

como a RenataFA disse....Provavelmente deve ter nome duplicado de algum atributo ou componente.

t+ e boa sorte

Então, estão certos e não estao na classe principal. Quanto ao escopo, não sei se pode ter a ver, mas algums codigos para baixo dão erro quando insiro esse codigo. Segue toda a classe:

import Classes.Musica;
import Servicos.ServicoMusica;
import java.sql.SQLException;

Isso não poderia ser erro de outras classes certo? Afinal são só objetos gráficos da própria classe.

\o/, erro tosco, uma simples chave que não deveria existir, ta ai o codigo certo, lembrando que tem que ter construtor na classe Musica para ele nao dar erro.
