Hibernate3 with JBoss4.0.4

javapro · **Joined:** Fri Jul 07, 2006 12:52 am **Posts:** 3

Folks,
I am a newbie with Hibernate and JBoss as well, trying to explore and learn these technologies together. Read articles and books, still have difficulty getting them together working. Do I have to bundle these in WAR or EAR file to get them working? Here's what I have:

Code:

Application Structure
=============

enterpriseApp
  - com.modelObjects
       - Person.class
       - Person.hbm.xml
  - META-INF
       - hibernate-service.xml
  - WEB-INF
       - jboss-web.xml
       - web.xml

Content of hibernate-service.xml
=====================
<server>
   <mbean code="org.jboss.hibernate.jmx.Hibernate" name="jboss.jca:service=SessionFactory">
      <attribute name="DataSourceName">java:/hibernateRnD</attribute>
      <attribute name="Dialiect">org.hibernate.dialect.Oracle9Dialect</attribute>
      <attribute name="SessionFactoryName">java:/hibernate/SessionFactory</attribute>
      <attribute name="ScanForMappingsEnabled">true</attribute>
   </mbean>
</server>

Content of jboss-web.xml
================
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jboss-web PUBLIC "-//JBoss//DTD Web Application 2.3V2//EN" "http://www.jboss.org/j2ee/dtd/jboss-web_3_2.dtd">

      <jndi-name>java:/hibernate/SessionFactory</jndi-name>
   </resource-ref>      
</jboss-web>

Content of web.xml
=============
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
   xmlns="http://java.sun.com/xml/ns/j2ee"

  </resource-ref>

  <welcome-file-list>
     <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

Snippet of Codes for Accessing reference to hibernate
===================================
Session session = null;
try{
     SessionFactory sessionFactory = getHibernateSessionFactory("java:/hibernate/SessionFactory");
     session = sessionFactory.openSession();
}catch(Exception e){
     throw new ServiceLocatorException(e);
}

Accessing this throws the following exception:
javax.naming.NameNotFoundException: hibernate not bound

Can someone point out me why this is happening? I am not making EAR but WAR.

Also, I am certain about name of the MBean which is name="jboss.jca:service=SessionFactory" - just followed some other example. is jboss.jca:serice standard? or can be replaced by anything I want? In another word, why jboss? why jca? why :service? Following the documentation, I copied "sessionFactory" from the SessionFactoryName - is it right? what should be there?

It would be a great help if someone can educate me. Thanks.

I think there's a way on how to retrieve the SessionFactory object from the MBean instead of using InitialContext.lookup() method. Check on the JBoss/Hibernate docs on how to do this.

I did try using Session and InitialContext but no success. Please help me.
Thanks.

I think you may want to use something similar to this code instead of binding Hibernate as a service:

package util;

import org.hibernate.*;
import org.hibernate.cfg.*;

public class HibernateUtil {

private static final SessionFactory sessionFactory;

static {
try {
// Create the SessionFactory from hibernate.cfg.xml
sessionFactory = new Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Make sure you log the exception, as it might be swallowed
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}

public static SessionFactory getSessionFactory() {
return sessionFactory;
}

}

In the sample above you'll have access to session factory from your servlet like: HibernateUtil.getSessionFactory()

I forgot to add that if you REALLY want to deploy it as enterprise app you need a structure like this:

myapp.ear:
myapp.sar:
META-INF:
jboss-service.xml
myapp.war:
WEB-INF:
classes/com/modelObjects/
jboss-web.xml
web.xml
myapp-ds.xml

No I don't want to deploy it as an enterprise app right now. I just would like to get it working as a web application. However, I do like to use it as JBoss service. Please let me know how I can implement Hibernate as JBoss service. However, also, I will try the way you suggested.

I still have a question though that can you please tell me more about the MBean's name's value - name = "jboss.someName:service=AnotherName" ?

is "jboss" is required?
What would the "someName" be? could it be anything I want?
what about the AnotherName - could it be anything? Hibernate or JBoss does not have clear explanation about how and what each of these names are associated with.

I appreciate your dropping by here to help me.
thanks.

Create HAR file which will include all POJO and hbm.xml file.Also create hibernate-service.xml file like below :

<server>
<mbean code="org.jboss.hibernate.jmx.Hibernate" name="starwood.ips:service=Hibernate">
<attribute name="DatasourceName">java:/any name</attribute>
<attribute name="Dialect"> your Dialect</attribute>
<attribute name="SessionFactoryName">java:/hibernate/any name</attribute>
<attribute name="CacheProviderClass">org.hibernate.cache.HashtableCacheProvider</attribute>
<attribute name="ShowSqlEnabled">true</attribute>

</mbean>
</server>

That will expose Hibernate as MBean service on JBoss.

Thanks
