[CDO] Migrating to RC2 - driver not found [message #687121]

installed together with dom4j and javax.persistence and newer version of
MySQL driver. Unfortunately I'm now getting ClassNotFoundException:
com.mysql.jdbc.Driver. I tried to go back to the previous version of the
driver (5.1.7) but that didn't help. Hibernate just can't see the
driver. Any ideas?

Hi Michal,

All our p2 repositories (except the composite ones) contain an HTML page that, among other things, points to a bookmarks.xml file:

https://hudson.eclipse.org/hudson/job/emf-cdo-integration/lastSuccessfulBuild/artifact/result/site.p2/index.html
https://hudson.eclipse.org/hudson/job/emf-cdo-integration/lastSuccessfulBuild/artifact/result/site.p2/bookmarks.xml

You can import this XML file into p2 (--> Available Software Sites) so that all needed dependencies are located/installed automatically.

BUT: In the case of Hibernate I always experienced problems that are possibly caused by ambiguous contributions from multiple projects. I could always work around that by *pre-installing* all features from the Elver.org repository.

Cheers
/Eike

Hi,

I have the same problem with Hibernate 3.6.0 and its dependencies installed from the Elver update site. But if I put "DynamicImport-Package: *" into this hibernate plugin's OSGi manifest file, it works and the com.mysql.jdbc.Driver class can be found.
I have installed the previous version Hibernate 3.3.2 from the sourceforge update site and I have no driver problem but the hibernate plugin manifest file from the sourceforge already has the "DynamicImport-Package" header.
Did the "DynamicImport-Package" header become obsolete in the Hibernate 3.6.0 bundle?

Regards,
Rumburak

I've cc'ed Martin for this question.

I created a new hibernate plugin on the elver.org update site. Can you give it a try?
