[maemo-users] OpenJDK / Sun JRE & MicroEmu

I installed Sun's JRE, 1.6.0_10 on my N900.  I managed to get command line
java applications to run, but did not get as far as getting Java ME MIDlets
to run.  It may be possible, I just didn't get that far.

However, this might be a better question maemo-developers list, which also
talks a lot about Scratchbox, which is the testing environment most
developers use on X86 hosts.

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

* 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?
