Problem while using MMAPI

[sachinwarang]

Hi firend,
I'm using MMAPI in one of my application to play audio file from resource .But while prefetching it is throwing "java.lang.StringIndexOutOfBoundsException: String index out of range: -1" .

Can anyone give me some idea,why it is throwing this application error ?
And how to recover this problem?

code:

try
{

String loc = "/vibrate.mid";

InputStream is = getClass().getResourceAsStream(loc);

player = Manager.createPlayer(is,"audio/midi");

player.realize();

player.prefetch();

player.start();
}
catch (IOException ioe) {
al = new Alert("Alert","Error while enabling vibration using MMAPI(iMelody)invalid URL or InputStream cannot be formed.",imageError[0],AlertType.ERROR);
//wait for user to acknowledge the alert
al.setTimeout(Alert.FOREVER);
//Display alert,show main form when done
midlet.display.setCurrent(al,this);
System.err.println("Enable to vibrate using Nokia UI."+ioe);
}
catch (MediaException me) {
al = new Alert("Alert","Error while enabling vibration using MMAPI(iMelody)Player cannot be created.",imageError[0],AlertType.ERROR);
//wait for user to acknowledge the alert
al.setTimeout(Alert.FOREVER);
//Display alert,show main form when done
midlet.display.setCurrent(al,this);
System.err.println("Enable to vibrate using Nokia UI."+me);}
catch( Exception e ){
al = new Alert("Alert","Error while enabling vibration using MMAPI(iMelody).",imageError[0],AlertType.ERROR);
//wait for user to acknowledge the alert
al.setTimeout(Alert.FOREVER);
//Display alert,show main form when done
midlet.display.setCurrent(al,this);
System.err.println("Enable to vibrate using Nokia UI."+e);
}

Could it be that the problem is in the catch clause? So that there is an exception thrown at some point and when you are handling the exception you happen to throw another exception (this time for StringIndexOutOfBound)
Could you try replacing the System.err.println("..." + e); with System.err.println("..." + e.toString()); or the whole statement with a simple e.printStackTrace()
