Hello,
thanks for your feedback, Gavin.

Unfortunately, I get a 404 error on this site.
I understand, that I need a mqsql-driver, for example
mysql-connector-java-5.1.7.tar.gz
But how can I persuade the eclipse update tool to
load the mysql-bridge? I don't think, that it would
be sufficient to add the driver to the class path
in the run-configuration. (This might help the
application (the CDO server) to find the driver,
but I don't think, that it will make the update
mechanism happy.)
Still confused
Harald

Hi Harald,
Update sites will often give a 404 error (and other errors) in a browser, they will still work fine in the update
manager. Have you tried in the update manager in Eclipse?

Hi,
I just had to remove the Derby and the H2 driver from
http://net4j.sourceforge.net/update/downloads/ because they caused
conflicts with the corresponding bundles from the Eclipse Orbit
repository, where they have been added after CDO 2.0 GA.
Generally you can best find out about the locations where the build
system pulls dependencies from with our Buckminster RMAP file:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.emf/org .eclipse.emf.cdo/releng/org.eclipse.emf.cdo.releng/build.rma p?root=Modeling_Project&view=log
It's not the easiest format to read but in this particular case you'd
find something like:
<rm:searchPath name="orbit">
<rm:provider componentTypes="eclipse.feature,osgi.bundle"
readerType="p2" source="false" mutable="false">
<rm:uri
format=" ${eclipse.downloads}/tools/orbit/downloads/drops/R2010051920 0754/updateSite "/>
</rm:provider>
</rm:searchPath>
Please use
http://download.eclipse.org/tools/orbit/downloads/drops/R201 00519200754/updateSite
to install Derby or H2 drivers ;-)
Cheers

Please also note that the CDO 3.0 distribution ships with H2 and Derby
drivers.

For a Net4j DB *adapter* bundle to be installable via p2 you need its
corresponding (3rd party) *driver* either being already installed or
findeable by p2. An example:
If you want to use CDO with Mysql then you
1) Install the Mysql *driver* bundle via p2 from
http://net4j.sourceforge.net/update/
2) Point p2 to the CDO repo of your choice (e.g. 2.0) and install the
Mysql DB *adapter*
If that does not work for you I need to know once more and in detail
when/where you're having issues.
