Convert to Flash (from applet)

We have a java applet that we would like to convert to Flash. It has about 4 GUI classes and 16 logical/domain classes, and some unit test classes. The applet communicates with a server application via HTTP POST and JSON The applet draws lines and circles on a 2D canvas and accepts input from the user via mouse clicks. It is quite simple and all the logic is already implemented in java code. It just needs to be replicated. The existing java applet code can be checked out from a provided SVN repository. The new flash/flex/actionscript code will need to be checked in to a provided SVN repository with clear instructions about how the Flash artifact can be built from the source code.
