Location of persistence.xml inside a .war file?

[stwhit]

I'm using JBoss AS 6.0.0.M3.  One of the features I'm trying to use is the ability to package EJBs directly within a .war file (without having to place the EJBs in a .jar file).  I also use JPA persistence, and I'm trying to find a place to put persistence.xml inside my .war that JBoss will recognize.  So for I've had no luck.  Is it possible to place persistence.xml (and JPA entity classes) directly in a .war, or do I need to package them as a .jar?

Thanks.

This might help http://community.jboss.org/wiki/EJB31inAS600M2. Check the section titled "Deployment of EJBs through a .war file"

Post edited: I read only the first half of your question. Your real question is not about EJBs but about where to place the persistence.xml file. You can place that file in WEB-INF/classes folder and package the JPA classes in the WEB-INF/classes folder too.

Hmmm....  I believe that's what I'm doing, but it doesn't seem to be  working.

$ jar tf  dist/offerrepository.war
META-INF/
META-INF/MANIFEST.MF
WEB-INF/
WEB-INF/classes/
WEB-INF/classes/org/
WEB-INF/classes/org/myorg/
WEB-INF/classes/org/myorg/offerrepository/
WEB-INF/classes/org/myorg/offerrepository/ejb/
WEB-INF/classes/org/myorg/offerrepository/jpa/
WEB-INF/classes/org/myorg/offerrepository/web/
WEB-INF/classes/org/myorg/offerrepository/ejb/OfferRepositoryBean.class
WEB-INF/classes/org/myorg/offerrepository/jpa/Offer$Gender.class
WEB-INF/classes/org/myorg/offerrepository/jpa/Offer.class
WEB-INF/classes/org/myorg/offerrepository/web/SearchServlet.class
WEB-INF/classes/persistence.xml
WEB-INF/web.xml

My EJB injects an EntityManager as such:

@PersistenceContext(unitName = "OfferRepository")
private EntityManager entityManager;

My  persistence.xml contains this:

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"  version="1.0">
    <persistence-unit name="OfferRepository"  transaction-type="JTA">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:/OfferRepositoryDS</jta-data-source>
       <class>org.myorg.offerrepository.jpa.Offer</class>
       <properties>
          <property name="hibernate.dialect"  value="org.hibernate.dialect.MySQLDialect" />
       </properties>
    </persistence-unit>
</persistence>

And when I deploy to JBoss, I receive this error  message:

DEPLOYMENTS IN  ERROR:
   Deployment  "vfs:///D:/jboss-6.0.0.20100429-M3/server/default/deploy/offerrepository.war"  is in error due to the following reason(s):  java.lang.IllegalArgumentException: Can't find a persistence unit named  'OfferRepository' in  AbstractVFSDeploymentContext@32823696{vfs:///D:/jboss-6.0.0.20100429-M3/server/default/deploy/offerrepository.war}

Any idea what I'm doing wrong?  Thanks for the help.

Sorry, forgot about this thread. Were you able to fix this? If not, can you please attach a sample application here, which reproduces this problem. Although I haven't checked, I would expect that we have a testcase for this kind of deployments.

Have you tried placing it like this?

WEB-INF/classes/META-INF/persistence.xml

That worked.  Thanks!

Thanks a lot .
Spent 2 hours figuring it out.
