Custom Java apps/booklets on Kindle?

I've seen two confirmations that Kindle runs Java in the blogs recently ([1] and [2]). Has anyone tried running custom apps yet?

Cheers,
Julien

It's actually JavaScript not Java that the Kindle supports.

From the user guide:

Quote:
CHAPTER 6 Accessing the Web
Your Kindle comes with an Experimental application called Basic Web which is a Web browser that is optimized to read text-centric Web sites. It supports JavaScript, SSL and cookies but does not support media plug-ins (Flash, Shockwave, etc.) or Java applets.

It might support a Java servlet.

The browser supports JavaScript, but from [1]:

The main GUI and most of the back-end code is written in Java. The framework is quite elaborate and can be extended with extra "booklets".

Java indeed

The browser does indeed support javascript, but that is not what I am talking about.
As igorsk's and others research has shown, the applications on the Kindle are written in Java.
Igor decompiled some of the apps already, and that is how he found about the undocumented keyboard shortcuts.

The question is can custom Java applications be loaded onto the Kindle?
The kind of applications which would be cool: calendar, manga reader, RSS reader, communication (IM, email, ...), better audiobook support,...

Thanks,
Julien

Igorsk mentioned in an interview something about creating a sample java applet (booklet). Did this ever happen?

I did create a skeleton applet but it doesn't really do anything and you have no way to call it. I also need to check if it works with 1.0.4 and later; Amazon obfuscated a lot of class names so I'm not sure if a non-obfuscated version will load. One of these days I need to finalize it and post about it...

Can the SD card be made to autorun? That trick is what was done to get applications on the Sony.

Any luck with this?

The potential of custom apps on Kindle is still very interesting.
Do you know if igor or anyone succeeded in running a custom app on a Kindle?

Thanks,
Julien

I'm dying to find out if this could be done. I've got some great app ideas.
