Hi and welcome to DaniWeb!

I think there's some confusion here because I'm not seeing where this would be JSP.

This is a JavaScript function that would run client-side, not server-side.

It uses an ActiveX object, which will only work in Internet Explorer, again client-side only.

This file you're deleting would have to be located on the clients' PC. Are you intending to delete a server-side file?

Permissions in Internet Explorer would have to be set such that this site would be trusted to run ActiveX functions, additionally to modify files on the client machine.
