Toolkit.getDefaultToolkit().beep() does not work

[adelfa]

Why Toolkit.getDefaultToolkit().beep() does not work in built-in speakers or in motherboard buzzers but it works if external speakers are connected? If I will disconnect the external speakers it really wont work. Any ideas?

the default toolkit beep uses the os system alert, not the mother board beep.

if you out put the ascii bell (no. 7) to the command line (system.out.println) you should get a beep on the mother board

Ah okay thanks for the information. I forgot to tell but I also tried your suggestion but still no beep at all. What could be the problem?

[berkeleybross]

what os are you using?
can u normally here the beep from other programs?

if you put "echo ^G" into a terminal / command prompt you should hear it
(^g achieved by holding ctrl + g)

[adelfa]

Ahm Windows. Yes I heard the beep.

ok...
whats the code your using to try and generate the beep?
post it here

and is there any output at all to command line?

[adelfa]

Here's the code:

if (product == null) {
System.out.println("beep here");//debug
//Toolkit.getDefaultToolkit().beep();

//System.out.print( '\u0007' );
//System.out.print( (char)0x07 );

System.out.println("\007");
System.out.flush();

javax.swing.JOptionPane.showMessageDialog(null, "Product does not exists");

}

There is no output when I print character 7.

[berkeleybross]

System.out.print("\007");
System.out.flush();

should work when you run it in command prompt.
however, It doesnt work in netbeans, it just prints a space - not sure why.

Did you run that program in an IDE or from command prompt?

[adelfa]

IDE. So would that means the problem is the IDE? Okay might as well try in the command prompt.
