current:
        try
        {
            return Class.forName(className);
        }
        catch (ClassNotFoundException e)
        {
            throw new NoClassDefFoundError(e.getMessage());
        }

and it should be:
        try
        {
            return Class.forName(classNamej,false,CurrentClass.getClass().getClassLoader());
        }
        catch (ClassNotFoundException e)
        {
            throw new NoClassDefFoundError(e.getMessage());
        }
