[CDO] DBStore postresql [message #1388217] Thu, 26 June 2014 02:13 Go to next message

Hello everybody,

I started using CDO with the Hibernate/Teneo store and recently tried out the other stores that are available. One of the stores I am currently looking at is the dbstore with the postgresql dbAdapter. When importing one of my models into the repository I get the following exception:

org.eclipse.emf.cdo.util.CommitException: Rollback in DBStore: org.eclipse.net4j.db.DBException: org.postgresql.util.PSQLException: Die Typwandlung für eine Instanz von [B nach Types.BLOB ist nicht möglich. (Cannot cast an instance of [B to type Types.BLOB)

At the same time the server throws the following exception:

Does anyone have an idea what might be wrong with my model or my configuration? The dbstore (mysql) and hibernate/teneo store work just fine with the models that I use.

I am currently using CDO 4.3.0.v20140520-18231 and PostgreSQL 9.3.

Thanks in advance!

Hi,

I have/had the same problem. Perhaps there is a real solution?

For now had to modify org.eclipse.emf.cdo.server.internal.db.mapping.CoreTypeMappings$TMBytes. Instead of DBType.BLOB I use DBType.BINARY for the FACTORY instance.
