I'm sure that other people have had this problem before as well, so I'm hoping
for some help.
I was working with CDO to do some persisting of my emf model to a database. I
started with the default horizontal mapping provided by CDO, but found that it
was terribly slow (ending with more than a minute to commit about 10000
objects). So, I decided to try to use the hibernate mapping, but now I'm ending
with NoClassDefFound errors. The culprit comes on a simple line:
return CDOHibernateUtil.createStore(new TeneoHibernateMappingProvider());
My stack trace is this:
java.lang.NoClassDefFoundError: org/hibernate/Interceptor
at
org.eclipse.emf.cdo.server.hibernate.CDOHibernateUtil.create Store(CDOHibernateUtil.java:28)
at
ca.uvic.chisel.hsqldb.CDO.internal.HSQLDataPortal.createStor e(HSQLDataPortal.java:213)
at
ca.uvic.chisel.hsqldb.CDO.internal.HSQLDataPortal.createRepo sitory(HSQLDataPortal.java:149)
at ca.uvic.chisel.hsqldb.CDO.internal.HSQLDataPortal.init(HSQLD ataPortal.java:84)
at
ca.uvic.chisel.hsqldb.CDO.internal.HSQLDataPortal.getSession (HSQLDataPortal.java:117)
at
ca.uvic.chisel.javasketch.internal.CDOProgramSketch.getPorta l(CDOProgramSketch.java:153)
at
ca.uvic.chisel.javasketch.persistence.internal.PersistTraceJ ob.runTest(PersistTraceJob.java:172)
at
ca.uvic.chisel.javasketch.persistence.internal.PersistTraceJ ob.run(PersistTraceJob.java:105)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)
I've tried to follow the set-up guidlines for teneo, etc. That is, I have a
plugin that contains the hibernate jars, and the packages are exported.
Eclipse-BuddyPolicy is set to dependent, and the dependency is re-exported in my
plugin. So, any ideas? Using CDO version 1.0.8. Thanks.

Del,
I hope that Martin or others can help with the Hibernate questions.
But I'd like to point out that the performance of the DBStore has been
drastically improved in the 2.0 stream.
With some special configuration properties (e.g. turn off auditing, ...)
it should scale pretty well now.
Maybe Stefan can explain more details when he is back from vacation next
week...
Cheers

Yes, and I would prefer to use the DBStore as well (I don't want to have to
distribute hibernate), but I don't usually like to develop in the milestone
releases of Eclipse. Though I may just suck-it-up for this one because I don't
want to have to scrap EMF and my CDO work.
If I were to go to Galileo and CDO 2, do you have any other tips for performance
enhancements?

I'd definitely start here:

OK, I'm trying 2.0 now, but all of my code is broken. I'm trying to follow the
instructions in this little tutorial:
http://wiki.eclipse.org/Run_a_CDO_container_inside_eclipse_r untime
I need to have the "Lazy Populating Package Registry", but
config.setLazyPopulatingPackageRegistry() is now missing. What do I do?

Nothing, it's the default now ;-)

And now, HSQLDBDataSource won't load either! Same basic problem as I mentioned
with hibernate before, but now CDO can't find org.hsqldb.jdbc.jdbcDataSource. It
is definitely in my plugin, and it is definitely being exported. What is going on?

Never mind, I was just forgetting to export the version number of the packages.
I'm guessing that is what was going wrong with hibernate as well.
And, wow, the new CDO mapping is a LOT faster. My commits went from taking more

Good to hear that! And you will find out that the 2.0 stream not offers
greatly improved performance but also a lot of new functionality and
configurability. Since Ganymede we added 141 enhancements:
