Hibernate sessionFactory and JNDI

hi everyone.
I have a little problem with binding Hibernate SessionFactory to JNDI.
I'm always getting that messages in Log, when i'm deploying my web-app on jBoss server (5.1).

Code:

25:22,049 INFO  [SettingsFactory] Named query checking : enabled
25:22,150 INFO  [SessionFactoryImpl] building session factory
[b]00:25:22,154 INFO  [SessionFactoryObjectFactory] Not binding factory to JNDI, no JNDI name configured[/b]

hibernate.cfg.xml

Code:

<hibernate-configuration>

 </session-factory>

persistance.xml

Code:

<persistence-unit name="seam_test" transaction-type="JTA">
      <provider>org.hibernate.ejb.HibernatePersistence</provider>
      <jta-data-source>java:/seam_testDatasource</jta-data-source>
      <properties>

         <property name="jboss.entity.manager.factory.jndi.name" value="myfactory"/>
      </properties>
   </persistence-unit>

components.xml

Code:

....
<persistence:hibernate-session-factory auto-create="true"
  cfg-resource-name="hibernate.cfg.xml" name="hibernateSessionFactory"/>
 <persistence:managed-hibernate-session auto-create="true"
  name="hibernateSession" session-factory-jndi-name="hibernateSessionFactory"/>
....

mysession.java, base class DAO.java, local interface

Code:

public class DAO {
   protected DAO() {
      }
      //some methods

      private static final Logger log = Logger.getAnonymousLogger();      
              //HERE IS IT!!
      @In
      public Session hibernateSession;
}

@Stateless
@Name("mysession")
public class mysession extends DAO implements mysessionLocal {
   @PostConstruct
   public void init() {
             System.out.println("INIT mysession bean");
    }
           //some methods
}
@Local
public interface mysessionLocal {
          //methods
}

I write simple web-application using SEAM framework, and i decided to use Hibernate instead JPA in my stateless EJB.
I want to INJECT (@In) Hibernate Session in every created EJB.
Tell me, what is wrong here, why i cant to inject Session to EJB?
i'm always getting this, when my EJB constructed:

Code:

00:31:10,091 ERROR [TxPolicy] javax.ejb.EJBTransactionRolledbackException: SessionFactory not found in JNDI: hibernateSessionFactory

I suggest you reading the JBossAS ref doc.

I don't know what component.xml is. I don't recall JBoss5 server nor hibernate itself has one.

In JBoss5, you would normally create a <datasource> config inside a <myDSName>-ds.xml file in the $JBOSS_HOME/server/<profileName>/deploy directory (default is hsqldb-ds.xml). The datasource will automatically bind to JNDI. The dasource name should match to your persistence.xml with "java:" prefix.

You normally don't use <hibernate-configuration> when using JPA unless you explicitly reference so, and I don't see you doing so.

In EJB, you inject a EntityManger object by using @PersistenceContext annotation.

yes, i have seam_test-ds.xml file. it is ok.
here is it

Code:

<datasources>
      <local-tx-datasource>
      <jndi-name>seam_testDatasource</jndi-name>
      <use-java-context>true</use-java-context>
      <connection-url>jdbc:mysql://localhost:3306/seam</connection-url>
      <driver-class>com.mysql.jdbc.Driver</driver-class>
      <user-name>surly</user-name>
      <password></password>
      </local-tx-datasource>
</datasources>

components.xml - is a Seam components configuration file.

look, i don't want to use EntitiyManager object, which injected by using @PersistenceContext annotation.
I want to use Hibernate with EJB, i want to inject Hibernate Session object. But i dont know how :(
Can you help me with this problem?

I don't know about seam, but JBossAS allows you to inject a direct hibernate session in EJB with the same annot. Try

Code:

@Stateless MyBean implements LocalBean
{
    @PersisteceContxt
    org.hibernate.Session session;
    ...
}
