[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-6938) Clarify the use of getHibernateConfiguration and Configuration handling with JPA bootstrap

Clarify the use of getHibernateConfiguration and Configuration handling with JPA bootstrap ------------------------------------------------------------------------------------------ Key: HHH-6938 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6938 Project: Hibernate Core Issue Type: Task Affects Versions: 3.6.5 Reporter: Stephane Nicoll Hi, I am willing to register custom types automatically when our application starts. We are using JPA2 and the EntityManager. To do so I can use a method on the Configuration object (registerTypeOverride). When configuring the JPA container, the PersistenceProvider can be extended. That's what I am doing but I came to this code (Ejb3Configuration on 3.6.5) {code:java} /** * This API is intended to give a read-only configuration. * It is sueful when working with SchemaExport or any Configuration based * tool. * DO NOT update configuration through it. */ public AnnotationConfiguration getHibernateConfiguration() { //TODO make it really read only (maybe through proxying) return cfg; } {code} I believe there is a TODO here that may lead to a change that would disallow me to use the configuration object to register new types on startup. If this TODO gets ever resolved (why?), what could I do to register new types? Thanks
