I had thought I was on all the yocto-related mail lists (https://lists.yoctoproject.org/), but I wasn't aware of this layer until I just read through the repository list (http://git.yoctoproject.org/cgit/cgit.cgi/).

Thanks Koen and Ivan.  I now have both the jvm and compiler working on 
my embedded powerpc (started with OE meta-java last night)!

I'm still somewhat puzzled about the dynamics between Yocto and 
Openembedded, and I have come to conclusion that I need to watch both 
projects & mailing lists carefully & start asking some questions to get 
me out of the dark....

I think my initial question about an openjdk layer for yocto is still 
valid.  Although meta-java exists in OE and it makes use of the common 
meta folders in oe-core, the meta-java layer also makes use of some 
recipes in other OE layers (e.g, mercurial in meta-oe & fastjar, which I 
pulled from classic). These additional layers didn't seem to play nicely 
in the yocto poky tree, so I pulled the recipes and put them in my own 
layer.

This next question probably shows some of my ignorance with OE (& 
yocto), but what's the plan inside yocto for use of something like OE's 
meta-java?  Are yocto users just on their own, should there be a README 
for use of the OE layer in yocto, or maybe there should be a translation 
layer in yocto for use of popular or common OE layers?

Also, I was working from within master branches in both yocto poky & 
meta-java.  I found that I needed to fudge some recipes to get 
everything in meta-java to build.  I'll probably go back and rebuild 
from scratch again and see if there are some patches that I should send out.

Thanks again for the heads up on meta-java!
