closing a JDialog with a button

[Klaus Hansen]

moin,

i have a problem with the following code:

package testen;

	import java.awt.event.*;
	import javax.swing.*;

public class ProbDialogClose {

		static JFrame f = new JFrame("test");
		static JDialog dialog = new JDialog( f, true );

		ProbDialogClose() 
		  { 
		    f.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); 
		    f.setVisible( true ); 
		    showWelcomeMessage();
		    
		  } 

	    private void showWelcomeMessage(){
	    	JDialog dialog = new JDialog( f, true );
	     	dialog.setSize( 450, 400 ); 
		    dialog.setLayout(null);
		    
		    JButton closeButton = new JButton("Fenster schließen");
		    closeButton.setSize(150, 30);
		    closeButton.addActionListener( new ActionListener() { 
		    	  public void actionPerformed( ActionEvent e ) { 
		    		  closeWelcomeMessage();
		    	  } 
		    	} );
		    dialog.add( closeButton );
	    	dialog.setVisible( true );
	    }

	   private void closeWelcomeMessage(){
	    	System.out.println("hello");
	    	dialog.setVisible(false);
	    	dialog.dispose();
	    }

		public static void main( String[] args ) { 
			new ProbDialogClose();
		}
	}

i create a frame, than a dialog and with a click on the close button the dialog should be closed, so that i can work in the frame.
the control-line "hello" is displayed in the console, but the dialog doesn't disappear.

please help me...

// Should work now, look at the commented line below you should get the idea, a new JDailog object was getting created.
package testen;
import java.awt.event.*;
import javax.swing.*;

public class ProbDialogClose {

static JFrame f = new JFrame("test");
static JDialog dialog = new JDialog( f, true );

ProbDialogClose()
{
f.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
f.setVisible( true );
showWelcomeMessage();

}

private void showWelcomeMessage(){
//JDialog dialog = new JDialog( f, true );
dialog.setSize( 450, 400 );
dialog.setLayout(null);

JButton closeButton = new JButton("Fenster schließen");
closeButton.setSize(150, 30);
closeButton.addActionListener( new ActionListener() {
public void actionPerformed( ActionEvent e ) {
closeWelcomeMessage();
}
} );
dialog.add( closeButton );
dialog.setVisible( true );
}

private void closeWelcomeMessage(){
System.out.println("hello");
dialog.setVisible(false);
dialog.dispose();
}

public static void main( String[] args ) {
new ProbDialogClose();
}
}
