Hola amigos, gusto de saludarles, tengo un problema, a ver si me pueden ayudar.

Tengo una classe llamada SSHCommandExecutor que ejecuta un comando en un servidor unix remoto.

import com.jcraft.jsch.*;
import java.io.InputStream;

public class SSHCommandExecutor {

public static void main(String[] args) {
String host="nombredeservidor";
String user="nombredeusuario";
String password="password";
String command1="top -bn 1";
try{

java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
JSch jsch = new JSch();
Session session=jsch.getSession(user, host, 22);
session.setPassword(password);
session.setConfig(config);
session.connect();
System.out.println("Connected");

Channel channel=session.openChannel("exec");
((ChannelExec)channel).setCommand(command1);
channel.setInputStream(null);
((ChannelExec)channel).setErrStream(System.err);

InputStream in=channel.getInputStream();
channel.connect();
byte[] tmp=new byte[1024];
while(true){
while(in.available()>0){
int i=in.read(tmp, 0, 1024);
if(i<0)break;
System.out.print(new String(tmp, 0, i));
}
if(channel.isClosed()){
System.out.println("exit-status: "+channel.getExitStatus());
break;
}
try{Thread.sleep(1000);}catch(Exception ee){}
}
channel.disconnect();
session.disconnect();
System.out.println("DONE");
}catch(Exception e){
e.printStackTrace();
}

}

}
//fin de la clase

Como puedo hacer para que al presionar el boton "Ejecutar top -bn 1" despliegue en el text area la salida de la primera clase?

De antemano les agradezco.

Gracias por las respuestas amigos...
Estudiare entonces programacion orientada a objetos.

Saludos y gracias nuevamente

En todo caso, lo que yo quiero es que cuando se presiona el Jbutton, se ejecute la clase SSHCommandExecutor y se muestre el contenido en el JTextArea de la clase MenuExecutor.

El codigo es cierto que esta vacio pero es que es por que no se como llenarlo para que se muestre lo que quiero.

Saludos y gracias nuevamente
