JPA entities -- org.hibernate.TypeMismatchException
- by shane lee
Environment:
JDK 1.6, JEE5
Hibernate Core 3.3.1.GA, Hibernate Annotations 3.4.0.GA
DB:Informix
Used reverse engineering to create my persistence entities from db schema [NB:This is a schema in work i cannot change]
Getting exception when selecting list of basic_auth_accounts org.hibernate.TypeMismatchException: Provided id of the wrong type for class ebusiness.weblogic.model.UserAccounts. Expected: class ebusiness.weblogic.model.UserAccountsId, got class ebusiness.weblogic.model.BasicAuthAccountsId
Both basic_auth_accounts and user_accounts have composite primary keys and one-to-one relationships.
Any clues what to do here? This is pretty important that i get this to work. Cannot find any substantial solution on the net, some say to create an ID class which hibernate has done, and some say not to have a one-to-one relationship.
Please help me!!
