Introducing PluotSorbet

PluotSorbet is a J2ME-compatible virtual machine written in JavaScript. Its goal is to enable users you run J2ME apps (i.e. MIDlets) in web apps without a native plugin. It does this by interpreting Java bytecode and compiling it to JavaScript code. It also provides a virtual filesystem (via IndexedDB), network sockets (through the TCPSocket API), and other common J2ME APIs, like Contacts.

The project reuses as much existing code as possible, to minimize its surface area and maximize its compatibility with other J2ME implementations. It incorporates the PhoneME reference implementation, numerous tests from Mauve, and a variety of JavaScript libraries (including jsbn, Forge, and FileSaver.js). The virtual machine is originally based on node-jvm.

PluotSorbet makes it possible to bring J2ME apps to Firefox OS. J2ME may be a moribund platform, but it still has non-negligible market share, not to mention a number of useful apps. So it retains residual value, which PluotSorbet can extend to Firefox OS devices.

PluotSorbet is also still under development, with a variety of issues to address. To learn more about PluotSorbet, check out its README, clone its Git repository, peruse its issue tracker, and say hello to its developers in irc.mozilla.org#pluotsorbet!
