It looks like the approach of converting VFS urls to FILE urls is not working, I'm
going to reject the VFS change since its not really working.
Also, AS is allowed to return VFS urls by the JPA spec. Below is the javadoc for
getPersistenceUnitRootUrl():
{code}
/**
* Returns the URL for the jar file or directory that is the
* root of the persistence unit. (If the persistence unit is
* rooted in the WEB-INF/classes directory, this will be the
* URL of that directory.)
* The URL will either be a file: URL referring to a jar file
* or referring to a directory that contains an exploded jar
* file, or some other URL from which an InputStream in jar
* format can be obtained.
* @return a URL referring to a jar file or directory
*/
{code}
I think that the VFS url should fit the "or some other URL..."

Issue Type: Bug
Components: JPA / Hibernate
Affects Versions: 7.1.1.Final
Environment: $ java -version
java version "1.7.0_03-icedtea"
OpenJDK Runtime Environment (fedora-2.2.1.fc17.8-x86_64)

Reporter: Craig Ringer

Labels: compatibility, eclipselink, jpa, spec
Fix For: 7.2.0.Alpha1
Discussion on the EclipseLink bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=383200
("On JBoss AS 7, EclipseLink doesn't find entity classes unless they're
explicitly listed in persistence.xml") suggests that JBoss AS 7 may not be providing
a spec-compliant PersistenceUnitRootURL or contents.
EclipseLink can't scan the contents of a deployment for @Entity annotated classes, so
it doesn't find any entities unless they're explicitly named in persistence.xml .
http://docs.oracle.com/javaee/6/api/javax/persistence/spi/PersistenceUnit...
states:
{quote}
java.net.URL getPersistenceUnitRootUrl()
Returns the URL for the jar file or directory that is the root of the persistence unit.
(If the persistence unit is rooted in the WEB-INF/classes directory, this will be the URL
of that directory.) The URL will either be a file: URL referring to a jar file or
referring to a directory that contains an exploded jar file, or some other URL from which
an InputStream in jar format can be obtained.
*Returns*: a URL referring to a jar file or directory
{quote}
... and that's what EclipseLink expects. However, for EclipseLink class scanning to
function correctly an adapter class must be provided, such as the classes provided here:
https://community.jboss.org/wiki/HowToUseEclipseLinkWithAS7
to integrate EclipseLink with JBoss's VFS.
It may be worth investigating why this is necessary and whether the current behavior is
standards compliant.
