Subject [jira] [Updated] (ARIES-964) Support for bundle fragments
Date Wed, 26 Jun 2013 11:33:20 GMT

     [ https://issues.apache.org/jira/browse/ARIES-964?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tuomas Kiviaho updated ARIES-964:
---------------------------------

    Attachment: PersistenceBundleHelper.java

Here's a fixed version of the file that relies solely on BundleWiring. I guess a proper approach
would be to fallback to the current behaviour when running without BundleWiring support. It
also only utilizes only the first found match as did the previous implementation

> Currently it's possible to have both persistence.xml and Meta-Persistence: attribute
declared on fragment bundle, but it's not very practical because PersistenceUnitInfo#getClassLoader()
will return null causing providers to fall apart and there won't be any emf's available because
the bundle stays at RESOLVED state.
> I tried to circumvent this by declaring Meta-Persistence: at fragment's host, but required
a bit modification to PersistenceBundleHelper#findPersistenceXmlFiles to use BundleWiring#findEntries
(when it's available)
