[jboss-jira] [JBoss JIRA] (AS7-5062) PersistenceUnitRootURL for JPA providers may not be spec compliant

PersistenceUnitRootURL for JPA providers may not be spec compliant ------------------------------------------------------------------ Key: AS7-5062 URL: https://issues.jboss.org/browse/AS7-5062 Project: Application Server 7 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) OpenJDK 64-Bit Server VM (build 23.0-b21, mixed mode) $ uname -a Linux ayaki.localdomain 3.4.2-4.fc17.x86_64 #1 SMP Thu Jun 14 22:22:05 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Reporter: Craig Ringer Assignee: Scott Marlow 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.
