LWUIT running on the Jelatine VM

Although the Jelatine VM is still a work in progress, I got simple user interfaces working on it.

I used the LWUIMB demo and a X11 backend.

MIDPath on the iPhone

I started a port of MIDPath on the iPhone a few weeks ago. It was a bit easier than I expected.

First I had to understand how to use iPhone APIs from Java. Markus Heberlings from the MicroEmulator project helped me a lot in this task. I used Markus's library (straptease) to write a simple backend for MIDPath.

Next I added a directional pad to give a chance to people with large fingers to navigate through complex user interfaces.

Finally, I improved overall performances by compiling native backends for rasterization and SVG rendering.

Currently MIDPath runs on top of JamVM 1.5.1/Classpath and performances are correct for productivity applications. It should be faster when the iPhone backend will use OpenGL ES.

Available features:

• Full support of the MIDP2 widgets (LCDUI)
• JSR226/SVG
• JSR75/File Connection API
• Networking
  

Missing:

• Sound

In the video below, you can see a few midlets running on the iPhone:
