[jboss-jira] [JBoss JIRA] (AS7-6327) Create JPA service callback for invoking database migration

[jaikiran pai (JIRA)]

    [ https://issues.jboss.org/browse/AS7-6327?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12745432#comment-12745432 ] 

jaikiran pai commented on AS7-6327:
-----------------------------------

I thought there was already a (Hibernate specific?) way of doing this. Some property which points to a "DDL file". It might have meant to create a DB schema, but perhaps you can just use it to do whatever migration activity that you are looking for?

> Looking for a simple callback/listener mechanism so that we can invoke a database migration script before JPA persistent unit starts up and runs the Hibernate schema validation mechanism.
> Ideally, there would be a property within the persistence.xml that indicates which class to call.  It would also pass in/inject the datasource that is being used for the persistence unit. 
> Essentially, this would solve the lack of migration support in Hibernate itself.
