I was fighting with Jarpa not working on my phone (N70) nor emulator (5300) when I found the Java Security Domains page at Forum Nokia.
In fact, my code was working but, as it's not signed (Netbeans's own certificate doesn't seems to work on S40), no writing (Edit user data) was able.
I so followed the 2 tutorials on Forum nokia (S60 or S40) and I'm now happy to make Jarpa work on my phone and emulator! So let's try to add some cool features !
After Kuneri great post on FLite3 sand box problem, I thought it was impossible to make something more than graphical application or wallpaper on mobile with FLite!
