Calling a external SAP program from a view (for example the NotePad)

Hi all.

I trying to call a external SAP program (for example: the windows notepad). I have a view in a BSP with a link, when the link is pressed i trying to call the windows notepad using the function

ws_execute

but it don't work, i obtain an exception (NO_BATXCH) maybe because this function is obsolete. I don't know if exist some class that replace the function. If somebody knows some information about it please give me a reply urgently.
