Caros amigos,

Acontece que não consigo passar o texto capturado em jTextField1 para a Classe que faz a Comunicação da porta comm3.

podem me ajudar? vou postar os códigos.

package jcomm;

}

e na segunda classe ele pegaria o conteúdo do jTextField1 e mandaria para a porta comm3.

veja o código:

package jcomm;

import java.io.*;
import java.util.*;
import javax.comm.*;

            }
        }
    }
}

Fiquei perdido com todo esse codigo que voce postou…

poste somente a parte aonde esta com problema…

se o problema for pegar o que foi digitado no jTextField faca isso…


variavel_text_field.getText();

ou especifique melhor…

pegar a variável eu consigo.

quero fazer a mesma ser lida na segunda classe.

porque voce não passa apenas o texto para a segunta classe ?

faz um set na segunda tipo texto ser enviado sei la e passa o conteudo do textfield…

pegar a variável eu consigo.

quero fazer a mesma ser lida na segunda classe.

veja o código do botão de envio:

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
        
       // Aqui está o problema
       EnvioSimples.serial(jTextField1.getText());
       String[] args;        // TODO add your handling code here:

na outra classe deve ser lido para ser enviado, pois a mesma é quem faz a comunicação com a porta comm.

veja no segundo código.

GRato

cara ja de dei a dica agora se vira implementa isso, naum vou fazer o codigo para voce voce ja sabe o que tem fazer como fazer é problema seu…

Veja um exemplo: http://www.guj.com.br/java/55710-jdialog-devolvendo-valor-pra-jinternalframe#292687
