portableapps + XAMPP + tomcat = production application

Hi, I've got a web application using tomcat and mysql. I'm considering using portableapps to distribute the application to stand-a-lone users who
can run the application locally on their computers using a usb memory stick.
I've done some tests and it seems like working well with tomcat add-on and java set up.

I was wondering whether anyone has done something similar before and if someone can point me to examples of similar 'production' applications.
most appreciated,
