We want to replace our fat client application (developed using C#) with a web
application.
Wicket is one of the technology options we are considering.
Our question: Is it possible, and if so, how, to run a local process on the
users machine (normally run from the command line) from Wicket.
Thanks
Wicket: 1.4.16
FireFox:3.5.4
