Unable to start runtime due to invalid configuration




this is my code what i run :

package untitled2;

import java.awt.*;
import java.awt.event.*;
import java.applet.Applet;

public class Untitled1 extends Applet implements ActionListener {
TextField invoer;
Button plus, min;

}

// Verwerk de events
public void actionPerformed ( ActionEvent e) {
// Stap1: Als plus-Voorraad dan verhoog getal met 1
if (e.getSource() == plus) {
// Stap2: increment
getal++;
}
// Stap3: Als min-Voorraad dan verlaag getal met 1
if (e.getSource() == min) {
// Stap4: decrement
getal--;
}
// Stap5: Als enter-toets dan lees en converteer getal
if (e.getSource() == invoer)
getal= Integer.parseInt( invoer.getText() );
// Stap6: schrjf getal in het textField invoer
invoer.setText(Integer.toString(getal));


}
}


Please help me :(

"Unable to start runtime due to invalid configuration" is a JBuilder specific error, not a Java error

What can i do about it then . I tryed on 2 versions of Jbuilder the same problem :cry:

Perhaps asking in a JBuilder form would be a good idea. Or even better, don't use JBuilder at all
