Question

In the project I am using JPA with Hibernate implementation. All the entities are annotation based and listed in persistence.xml.

All Entities are packaged into jar.

I need to define a typedef for few properties(in all the entities) which are a string to a enum type. In DB the Columns is varchar. How can i achieve this?

Can I achieve this by adding hbm.xml and hibernate-cfg.xml?

Thanks in advance.

Straight from the documentation:

@org.hibernate.annotations.TypeDef and
@org.hibernate.annotations.TypeDefs allows you to declare type
definitions. These annotations can be placed at the class or package
level. Note that these definitions are global for the session factory
(even when defined at the class level). If the type is used on a
single entity, you can place the definition on the entity itself.
Otherwise, it is recommended to place the definition at the package
level.
