I wrote a MIDlet that uses JSR-120 functionality among other things. When I run it on a phone that doesn't support JSR-120 I get an error message for known reasons.
However, I want be able to run this code on a non-JSR120 phone while disabling the WMA(JSR-120) functionality.
In other words, I want to be able to run the same code on a variety of devices and be able to detect in run time which functionality is not supported and just not use it.

Taken from the Nokia block game example:

    private GameEffects makeGameEffects()
    {
        try
        {
            Class.forName("com.nokia.mid.sound.Sound");
            Class.forName("com.nokia.mid.ui.DeviceControl");

            // If no exception was thrown, use the vendor-specific APIs.
            Class clas = Class.forName("NokiaGameEffects");
            return (GameEffects) clas.newInstance();
        }
        catch (Exception e)
        {
            // The vendor-specific APIs are not available,
            // so use the 'stub' GameEffects instead.
            return new GameEffects();
        }
    }

You can use the same approach for any other optional API.

But shouldn't I also put an import statement at the beginning of the class

No. You are using Class.forName() so you shouldn't need it.
