Hi,

My application is using Spring+Hibernate with Mysql.
I'm tesing my dao with dbunit.
The test saving the domain object (contening a map) fail because of the thrown exception :

org.springframework.orm.hibernate.HibernateSystemException: No persister for: java.util.HashMap; nested exception is net.sf.hibernate.MappingException: No persister for: java.util.HashMap
net.sf.hibernate.MappingException: No persister for: java.util.HashMap
at net.sf.hibernate.impl.SessionFactoryImpl.getPersister(SessionFactoryImpl.java:344)

The Test loading the domain object succed.

What's wrong ?
Don't Hibernate support HashMap ?
Does I need to use a special Implementation of Map ?

Thanks.

Hibernate can persist instances of java.util.Map, java.util.Set, java.util.SortedMap, java.util.SortedSet, java.util.List, and any array of persistent entities or values. Properties of type java.util.Collection or java.util.List may also be persisted with "bag" semantics.
