Felipe Andrade and Alessandro Pace have created Jarpa, "Java Packaging for Flash Lite Developers".
The latest S60 phones support both Java ME and Flash Lite. Jarpa allows Flash Lite Developers to deliver their content as Java ME applications. The Java and Flash Lite can communicate via either files or a custom Symbian Server.
I have had a quick look and the current source code shows how to extract a Flash Lite file from Java resources and run it. There’s also an example demonstration application .jar.
It will be great when the source also shows how to communicate via files (and/or C++ server) both from the Java and Flash Lite sides.
This looks similar to Sony Ericsson’s Capuchin project except this is for Nokia S60.
