Hi!
Sorry about delay with answer. But everithing is working fine with Cayenne nighty build from 27th oct. Thank you Andrus!
> 1. Put "bootstrap..." line BEFORE "initialize.."
seems do nothing.
Actually a`ve had similar problems with classloader in JasperReports (which was used as jar).
At that point, to solve problem, I`ve made some changes in the eclipse core, but that chanege isn`t working with Cayenne (which now I`m using as plugin-from-jar). Anyway I don`t like this solution.
So, seems that`s really a problem. But at eclipse newsgroups they sad that in latest Eclipse releases (can`t say now which release, maybe 3.1.1) is introduced
"buddy classloading mechanism". Can`t say anymore, as I haven`t looked at this thing yet, but that`s a key for such problems with plugins, as I understand.

Hi Noban,
I hope you'll keep us informed with your progress in combining Cayenne
and Eclipse RCP. I was working on an RCP project in my spare time to
which I will probably try to add Cayenne at some point. Not sure
when I'll get back to that project, but any insights you come up with
will be helpful.
Thanks!
