We have not much experience with using Java in embedded systems.
Maybe others are in a better position to anser this question.
[However, ELDk 4.2 includes gcj, so you can do some Java development
within the ELDK context. Don't know if this is good enough for your

I guess it's impossible to tell the number of actual ELDK users -
many, many of them just download the code without ever becoming
visible on mailing lists or similar. You can get a little indication
for example by looking at the statistics collected by the Embedded
Linux polls performed by linuxdevices.com, but again this reflects
only a small fraction of the market.

There may be two explantions for this: (1) this list is not so old
(it was started only 10 months ago) and we do not make much rumour
about it; (2) quite a lot of people prefer not to use a public
mailing list but rather contact un directly - for example, most
requests regarding AMCC processors go through our commercial support

You might dig a bit in the PPC and U-Boot mailing list archives and
you probably would get a little impression of how many people use
ELDK, and what they think about it.

Yes, there are many things missing, or have not completely be changed
to arech/powerpc specifics yet. On the other hand, the documentation
is a wiki, so everybody is welcome to contribute. Unfortunately only
few actually do that.

There is nothing special in ELDK about using modules. You have some
Linux kernel directory somewhere where you configure and build your
Linux kernel (this is a prerequisite for building modules); then you
"cd" into the directory which holds your module source code and type
"make ARCH=powerpc -C <your_linux_tree> M=`pwd` modules". That's it.
