Playing sound when showing popup in Swing?

I have a frame which pops up whenever an event occurs.

Whenever that frame pops up, I want开发者_Go百科 a sound to be played.

How can I do that in Swing?

A very simple solution is using Toolkit.getDefaultToolkit().beep();

Subclass JDialog or similar and on the constructor/setVisible method of the derived class play a sound with one of the fore mentioned methods.
