I am using j2me polish to develop j2me application. I am using 5800 Xpress music device and i want to use touch screen functionality on my application, how to invoke that.

In my mobile as the navigation covers almost 50% of my screen so i disabled default navigation from my setting/installed application. Now i can see the application on full screen but cant type as i have no keypad. So how to invoke touch facility on my application.

I there any functionality in j2me polish built.xml

Thanks.
