[hibernate-dev] Exceptions while trying to use HibernateOGM

Hi,

Please post usage questions to the forum [1], as this mailing list is about
discussing the development of the Hibernate projects.

That being said, the exception is caused by configuring a non-existent
transaction factory class ("org.transaction.JDBCTransactionFactory"). Refer
to the reference guide [2] to learn more about bootstrapping OGM.
