JavaPOS and Javascript applet

Question

I have a RoR web application to which I would like to add some features. I want this application to be able to communicate with POS devices (cash drawer, printer). I believe that the best way to achieve this would be to implement a signed Java applet. My plan is to add some javascript that will send signals to applets telling about it, when to print, open a cash drawer, etc. The Java applet will use JavaPOS standards.

Questions:

1) Does that sound like a smart way to handle my situation?

2) Are there any applets like this (whether openource or commercially) that I could plug in? Or should I just write an applet for myself?

Answer 1

1) Of course :)

2) It will probably depend on POS targeting, whether it supports the JavaPOS standard, whether it has its own API, etc.
