Hi Eike, hi Martin,

after a few weeks, I'm back from vacation and switched back to work mode
this week.
First, let me give my congratulations for the graduation.

That said, I have persisting problems using CDO/Hibernate, some of which
I have a workaround (which is ok but not satisfying), for some I don't.

Here we go: (I updated to Ganymede (well, RC4 for now to be exact), and
thus to CDO 1.0.0)

Issue 1:
Is it intentional that CDO does not run out of the box when downloaded
binary as part of Ganymede?

=> Workaround: I have to copy the libraries to
eclipse\plugins\org.eclipse.emf.cdo.server.hibernate.librari es_1.0.0.v200806111412\lib


Issue 2:
When starting up, I get a

java.lang.NullPointerException

because at

URL entry = getBundleContext().getBundle().getEntry(".");
//$NON-NLS-1$

getEntry(".") returns null ...

=> Workaround: Imprt the Plug-In as source into the workspace

Net4j util seems to not like CDO as JAR bundles...

Refactoring problem?

meta.hbm.xml reads
<hibernate-mapping package="org.eclipse.emf.cdo.internal.protocol.model">
but should be
<hibernate-mapping package="org.eclipse.emf.cdo.internal.common.model">
now?

=> Workaround: edit meta.hbm.xml (as described) -
org.eclipse.emf.cdo.server.hibernate has been copied into workspace
alreday (see issue 2)


Issue 4:

org.hibernate.MappingException: entity class not found:
org.eclipse.emf.cdo.internal.common.model.CDOClassProxy

This class seems not to exist any more ...

=> no workaround! => STOPPER

Eike, Martin - can you please provide a working meta.hbm.xml file, so I
can continue with 1.0?


--- for now I'm comtinuing with my issues I have with 0.8.0 (as of end
of June) and which I suspect to be in 1.0.0 still:

Issue 5:

When calling getOrCreateResource() in a plugin activator's start()
method, I run into a deadlock.

=> Workaround: always do resource initialization lazyly


Issue 6:

EPackages only containing interfaces are not being taken by the package
manager -> ClassRefs can not be resolved (see Bugzilla – Bug 230387)

=> Workaround: introduce Dummy class in the package in question and
store one Dummy instance in the Database


Issue 7:

With all of these workarounds, I get to store and read my models in one
session alright.
However, when I close my application and reopen it, initialization fails
consistently when trying to get the contents of a resource:
getResource("/test").getContents() seems to not initialize the thread
context variables on the server:

Should I open bugs for these issues?
Can you provide quick fixes to my two stoppers?


Cheers,

Hi Stefan,
Sorry to hear that you have all these issues.
Regarding issue 3 and 4, I checked this in cvs on the 15th of june. So this should be solved in the
next build, or can you cvs?
I also solved another issue related to cdopackage persistence. So maybe this is related to one of
your other issues....

btw, I cross-posted to the emf newsgroup because cdo is graduating/has graduated.

gr. Martin

Hi Stefan,
Sorry to hear that you have all these issues.
Regarding issue 3 and 4, I checked this in cvs on the 15th of june. So this should be solved in the
next build, or can you cvs?
I also solved another issue related to cdopackage persistence. So maybe this is related to one of
your other issues....

btw, I cross-posted to the emf newsgroup because cdo is graduating/has graduated.

gr. Martin
