Ellen,

Looks like we have an addition to make to our package renamed. Can you file a bug?

https://bugs.eclipse.org/bugs/enter_bug.cgi?product=EPS%28EclipseLink%29

I believe all you need to do is to edit the provider in your persistence.xml:

	<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

I hope this works for you. Please keep us posted on your progress and results.

Doug

Subject: [eclipselink-users] Problem deploying - cannot find class
org.eclipse.persistence.jpa.EntityManagerFactoryProvider


Hi,
I am deploying EclipseLink to a Glassfish application server (replacing
TopLink Essentials).  I ran packageRename to update my persistence.xml file,
and when I deploy the application I get
java.lang.ClassNotFoundException:
org.eclipse.persistence.jpa.EntityManagerFactoryProvider
   at
com.sun.enterprise.server.PersistenceUnitLoaderImpl.load(PersistenceUnitLoaderImpl.java:143)

I looked at the contents of eclipselink.jar, and I don't find an
EntityManagerFactoryProvider in the location specified in
persistence.xml.  I did find a class in another package -
org.eclipse.persistence.internal.jpa.EntityManagerFactoryProvider, but
when I use this in persistence.xml, I get another exception on startup:
java.lang.ClassCastException
   at java.lang.Class.cast(Class.java:2951)
   at
com.sun.enterprise.server.PersistenceUnitLoaderImpl.load(PersistenceUnitLoaderImpl.java:137)
   at
com.sun.enterprise.server.PersistenceUnitLoaderImpl.load(PersistenceUnitLoaderImpl.java:84)
   at
com.sun.enterprise.server.AbstractLoader.loadPersistenceUnits(AbstractLoader.java:898)
   at
com.sun.enterprise.server.ApplicationLoader.doLoad(ApplicationLoader.java:184)
   at
com.sun.enterprise.server.TomcatApplicationLoader.doLoad(TomcatApplicationLoader.java:126)
...etc

Any hints as to what I'm doing wrong here?
Thanks,
Ellen
