Running Xlet in Set top box

Question

Hello everyone,
I just know how to do it with cardinal studio. It is generating a lot of files and i can import these files to the set top box.
I wrote my own (actulally i copied one ) script compilied it and imported it to the set top box. But it is not running. Do I need more files or a special structure ???? Would be pleased if anyone can help.
Kind Regards, tpc-claus
