MappingException when initializing the hbDataStore [message #427300]

Hello,

I had a perfectly working Teneo/Hibernate environment which now
generates a MappingException when initializing.

Here is the message in the exception:

"Could not determine type for:
org.eclipse.emf.teneo.hibernate.mapping.econtainer.EContaine rUserType,
at table: status, for
columns:[org.hibernate.mapping.Column(econtainer_class),
org.hibernate.mapping.Column(e_container)]"

it fails in when calling "buildSessionFactory()"

What could be the root of this problem?, my code didn't change,
but the following happened:

- I messed around with plugin dependencies, not sure all is "seen"
nowadays. Should I do some buddy policies? (My Hibernate jars and
needed auxiliary jars are in a separate plugin.

- The model could have changed, causing the problem? (I write "could" as
I likely did't change it, but who knows...).

Thanks for the help!

Hi Christophe,
Yes this is probably related to a classpath issue, hibernate throws this exception if it can't find the a class which
implements a type (in this case EContainerUserType). So I would check there.
The plugin containing the hibernate jars should have the eclipse buddypolicy set to dependent.
