[maemo-developers] OpenJDK / Sun JRE & MicroEmu (Java on Maemo)

[From: Gunter Ohrner]

(Following a suggestion on the users mailing list, I'm re-posting my 
question here.)

Hi!

I'd like to know if OpenJDK or Sun JRE work reliably and stable on the 
N900 and if MicroEmu works well enough to support some Java ME MIDlets, 
especially DB Railnavigator, a public transport travel planner.

Unfortunately I do not (yet) own an N900 and there does not seem to be a 
full emulator for testing the complete environment with ARM binaries on 
an x86 host.

I already found and read the following ressources, which sound rather 
promising:

* http://wiki.maemo.org/Java
* http://wiki.maemo.org/CamSWL_OpenJDK_on_N900
* http://talk.maemo.org/showthread.php?t=37405
* http://www.microemu.org/

I also tested DB Railnavigator with Java SE 6 and MicroEmu 2.0.4 on my 
x86 Linux Notebook, which seems to work pretty good, except some 
problems with fullscreen mode.

  (Lower half of page.)

Maybe someone already has some experience with OpenJDK / Sun JRE on his 
N900 and can tell me how usuable it works, and maybe someone could even 
test DB Railnavigator to check if it's starting and running sufficiently 
fast on this platform?

Greetings,
