I’m working with play.
I defined a private member in my model, hoping that JPA
wouldn’t try to handle it.
For some reason I get this error :
A JPA error occurred (Unable to build EntityManagerFactory): Could not determine type for: java.util.Map, at table: User, for columns: [org.hibernate.mapping.Column(myPrivateMember)]
How can I declare such private members without JPA crashing?
Use the @Transient annotation. It tells that the member is not persistable.
