Add "$wnd." in front of soundManager, e.g.:
public static native void playSound(String file)
/*-{
$wnd.soundManager.createSound({
id: 'aSound',
url: 'file.mp3'
});
$wnd.soundManager.play('aSound');
}-*/
The JSNI code is actually running inside of an iframe, not the
top-level browser window where soundManager was defined. GWT defines
"$wnd" to be a reference to that top-level window where the other
<script> tags were evaluated. For more details see the JSNI
documentation:
