Post Java execution, opening completed file on Windows

I have this program where I take in an excel file and manipulate it, I currently have it saving to a specific folder. Is there anyway I can have that file open on the user's computer after the program has executed.

Are we talking about a HTTP server / client browser architecture here?

No I have this little Applet / Application for my company, it simply takes in an excel file, highlights specific cells. Then saves the new file.

I want my program to open that file on the user's computer once it is saved.

EDIT: So the user doesn't have to go in and open the file him/herself.

By "Open that file" you mean "Launch Excel with that document opened", yes?

You would use Runtime.exec() to run a command like "cmd.exe /c start foo.xls" . The classic article on Runtime.exec() -- which you absolutely should read! -- is here. It will tell you exactly what to do, and what not to do.

Or use java.awt.Desktop's open method.

Thank you very much, I'll try it in a minute.
