I see. Thanks for the answers guys. I'm still a newbie in GWT. Your answers helped me understand more about GWT and how it compiles classes to javascript as well as the idea behind why webapp should not be allowed access to local resources. However, I think there are still exceptions though depending on the need and scenarios; in my case, my webapp is only used and accessed in a closed group/network and not for public/anyone's use.

For anyone who is also interested, What I did is I created a javascript code that uses an ActiveXObject implementation to run the external apps, in my case a windows calculator. Then using this code, I run this in an IE browser since only IE fully supports ActiveX implementation.

I haven't tried Braj's suggestion above but I think it's also one alternative that will work. Maybe I'll try playing with that approach this weekend.
