How to open warning/information/error dialog in swing?

I need standard error dialog with "Ok" button and "red cross" image. I.e. analog of org.eclipse.jface.dialogs.MessageDialog.openError()

Hello,

You can try out :

import javax.swing.JFrame;
import javax.swing.JOptionPane;

public class ErrorDialog {

  public static void main(String argv[]) {
    String message = "\"The Comedy of Errors\"\n"
        + "is considered by many scholars to be\n"
        + "the first play Shakespeare wrote";
    JOptionPane.showMessageDialog(new JFrame(), message, "Dialog",
        JOptionPane.ERROR_MESSAGE);
  }
}
