[jira] Commented: (ARIES-80) Provide persistence unit metadata parser

["Timothy Ward (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARIES-80?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12788689#action_12788689 ] 

Timothy Ward commented on ARIES-80:
-----------------------------------

I believe that creating a simple, common, performant, validating parser for JPA v1.0 and JPA v2.0 xml files as a utility would be very useful to the Aries project.

I would like to point out that there is no PersistenceUnitInfoService class defined by the draft specification of the OSGi Persistence Unit service or the Java Persisence API specifications. We should not base our implementation on non-public RFC documents. Especially when a more recent version of the specification is available as a public draft.

> The persistence.xml metadata is represented as a Map of properties in the PersistenceUnitInfoService class. Each XML element or attribute corresponds to a dedicated property name in the Map, and the extender must mine the file to create the associated property values. If no element or attribute was present in the persistence.xml file  there will be no entry in the Map for that property. Multiple XML elements are represented as properties with List values.
