How to generate barcode Code 39 without human-readable

Dear All,

I tried to create barcode Code 39 (bitmap output) without text
(human-readable). 
Is there possible to use java codes ?

/* ConfigType = "Code39" */
private static BarcodeGenerator getGenerator(String ConfigType) 
    	throws BarcodeException
    {
        DefaultConfiguration cfg = new DefaultConfiguration("cfg");
        DefaultConfiguration child = new DefaultConfiguration(ConfigType);
        cfg.addChild(child);
        Logger log = new NullLogger();
        BarcodeUtil util = BarcodeUtil.getInstance();
        BarcodeGenerator gen = util.createBarcodeGenerator(cfg, log);
        return gen;
    }

Thank you.

Regards,

Pietter
