The mentioned class is not part of the current 0.8 stream of CDO. I
suggest that you check out the sources via All.psf, see
http://wiki.eclipse.org/CDO_Project_Resources#Sources . You can also
download the SDK zip, but one with a 0.8.x version/I-build!

Does that help?

Hi Thomas,

I also started playing around with CDO about one week ago.
It is quite tricky to get a working environment, because CDO 0.7.1
(which you get from the update site) is quite outdated and getting the
current integration builds up with the correct dependencies is also
quite hard ;-)

What worked for me was using a clean Eclipse 3.4M4 with the latest EMF
integration build and then importing the team project set all.psf from:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.emf/org .eclipse.emf.cdo/develop/psf/pserver/All.psf?root=Modeling_P roject&content-type=text%2Fplain&view=co
(see also the description at
http://wiki.eclipse.org/CDO_Project_Resources#Sources).

Using that you can build and export the features yourself and be sure
that they run with your installation.

(BTW: don't try to build the doc and sdk features on windows as they
contain unix shell scripts).

Maybe Eike can comment on this, if there is an easier way to get CDO
running - this was my way which worked after trying and playing alot ;-)

Cheers,
Stefan

Hmm, I was not aware that there are difficulties with dependencies.
Could you please describe in more detail which version of CDO you wanted
to install into which version of Eclipse and which dependencies caused
the trouble?

The 0.7 stream of CDO is not maintained anymore although the respective
build-downloads should work with the dependencies given on the downloads
page.

The current 0.8 stream of CDO has dependencies on Eclipse 3.4, EMF 2.4
and Net4j 0.8. The HEAD of CVS should successfully build/run against
newer I-builds of Eclipse/EMF or at least against the most recent M-build.

I think part of the problem was that the source you provided in the
other thread didn't work for me at first.

I got very strange errors e.g. that an indirectly referenced class file
could not be found and at the same time I could not figure out what was
missing, because I had added every single *.cdo.* and *.net4j.* plugin
to the dependencies without any effect. So I tried to do a clean install
with Eclipse 3.3 which also failed for some reason I cannot remember.
Anyway, it did take me several tries to get a working environment ...


Cheers,
Stefan
