[CDO] why getCreationIme is Unsupported in HibernateStore [message #423669]

Hi I'm trying CDO with HibernateStore via Mapping file generated by Teneo

I have the org.eclipse.emf.cdo.server.hibernate version from CVS

my server is running

and when I try to connect to my CDO repository from CDO UI i have an
unsupportedOperationException from getCreationTime () method in
HibernateStore :

[ERROR] UnsupportedOperationException
java.lang.UnsupportedOperationException
at
org.eclipse.emf.cdo.server.internal.hibernate.HibernateStore .getCreationTime(HibernateStore.java:183)
at
org.eclipse.emf.cdo.internal.server.Repository.getCreationTi me(Repository.java:376)

In the HibernateStore code i Have

public long getCreationTime()
{
throw new UnsupportedOperationException();
}

so why this function is unsupported ?

Hi Tristan,
Currently the hibernate store does not keep the time when the repository was created. I am not sure
if this is really required or that returning a default date should also work. I have sent a question
about this to Eike. If I know more I will let you know.
You can also enter a bugzilla for this, then I have something to attach a solution to it.

Hi Martin
thank you for your answer

In fact it's not a problem for me I modify the code to return a default
value but it's a strange behaviour for a user who want to make a little
try of the techno and getting an unsupportingoperationexception.

An other thing is it normal to access to
org.eclipse.emf.cdo.server.hibernate just via CVS ? i didn't see a build
version

Hi Tristan,
The cdo.server.hibernate is included in the cdo builds which are published regularly.

Sorry, we're still working on including the HibernateStore into our
regular test suites so that such regressions don't happen anymore.

This method is mostly for setups that support auditing (historical
views) to constrain the "valid past". If it's not possible to detect the
time of the *first* creation of the store/repository then I think that
CDORevision.UNSPECIFIED_TIME is better than an exception. Martin told me
that this particular issue is fixed now (also by returning a the default
value CDORevision.UNSPECIFIED_TIME).

Can you please file a Bugzilla so that we can finally include the
hibernate feature into the regular distro?

Sorry, Martin is right: The hibernate feature is included in the CDO SDK!
With your Bugzilla we could include it into the cdo.server feature as
well...
