I then added some attributes/properties to a class and completed the mapping file. After deploying and testing the application I ran into the following hibernate exception:
org.hibernate.HibernateException: Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]
I really couldn’t figure out what was wrong and tried almost everything. I just overlooked a little tiny detail: I misspelled a getter-method in the Java class and this led to the exception above.
Maybe it is just me, but this error message could really be a little bit more specific.
