Session Bean can not find Entity Manager

julianhtun Jan 8, 2006 2:48 AM

I have checkout jboss-head and build it. I follow the TrailBlazer example.

[ Entity Beans PAR file ]
author.par
--META-INF
-- -- persistence.xml
-- -- MANIFEST.MF
-- -- org/jboss/ejb3demo/Article.class
-- -- org/jboss/ejb3demo/Author.class

[ Session Beans Archive ]
authors-bean.ejb3
-- org/jboss/ejb3demo/Authors.class
-- org/jboss/ejb3demo/AuthorsBean.class

Article.class and Author.class are entity beans.

persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<entity-manager>
 <name>articles</name>
 <jta-data-source>java:/DefaultDS</jta-data-source>
 <properties>
 <property name="hibernate.hbm2ddl.auto"
 value="create-drop"/>
 </properties>
</entity-manager>

AuthorBeans.java:

@Stateless
@Remote(Authors.class)
public class AuthorsBean implements Authors
{
 @PersistenceContext(unitName="articles")
 private EntityManager manager;

 public void addArticle(Author author, String title, String body)
 {
 manager.persist(author);
 author.addArticle(title, body);
 }
. . . .
}

When Entity is deployed:

Info Message:

00:03:17,921 INFO [JaccHelper] JACC Policy Configuration for deployment has been put in service
00:03:17,921 INFO [Ejb3Deployment] EJB3 deployment time took: 15
00:03:17,921 INFO [EJB3Deployer] Deployed: file:/C:/jboss/server/all/deploy/author.par

Error Message:

00:03:48,093 INFO [EJB3Deployer] Deployed: file:/C:/jboss/server/all/deploy/authors-beans.ejb3
00:03:48,109 ERROR [URLDeploymentScanner] Incomplete Deployment listing:

--- MBeans waiting for other MBeans ---
ObjectName: jboss.j2ee:service=EJB3,name=AuthorsBean

I Depend On:

--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: entity.manager:name=articles
State: NOTYETINSTALLED
Depends On Me:
jboss.j2ee:service=EJB3,name=AuthorsBean

What am I doing wrong?

Thanks,

It seems that schema of "persistence.xml" has been changed with xmlns="http://java.sun.com/xml/ns/persistence".

Try with this other one "persistence.xml":

<?xml version="1.0" encoding="UTF-8"?>

<persistence-unit name="articles" transaction-type="JTA">
<jta-data-source>java:/DefaultDS</jta-data-source>

</persistence-unit>

Sorry, the previous XML has been submited incorrectly:

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="articles" transaction-type="JTA">
<jta-data-source>java:/DefaultDS</jta-data-source>
<properties>
<property name="hibernate.hbm2ddl.auto"
value="create-drop"/>
</properties>
</persistence-unit>
</persistence>

Maybe now:

<?xml version="1.0" encoding="UTF-8"?>

<persistence-unit name="articles" transaction-type="JTA">
<jta-data-source>java:/DefaultDS</jta-data-source>

</persistence-unit>

Try with this other one "persistence.xml":

<persistence xmlns="http://java.sun.com/xml/ns/persistence">
 <persistence-unit name="articles" transaction-type="JTA">

The error was obvious - I forgot @Entity on Author class.
