- download beta runtime from javafx.com
- download netbeans FX support from same site
- create new JavaFX project and add next lines

        MediaPlayer mediaPlayer = new MediaPlayer(new Media("http://webcast-west.sun.com/oow2010.flv"));
        mediaPlayer.setAutoPlay(true);
        root.getChildren().add(0, new MediaView(mediaPlayer));

- run project -- it will work fine
- click Clean & Build to generate plugin version
- open dist/ProjectName.html

I'm getting next error
