Hi
I am in big trouble folks. i am not able to configure getting SessionFactory from JNDI . Please help me details about the cfg and error stackTrace are mentioned below.

This is my cfg file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
<session-factory name="SessionFactory">
<property name="connection.pool_size">1</property>
<property name="hibernate.session_factory_name">SessionFactory</property>



<property name="dialect">org.hibernate.dialect.SQLServerDialect</property>


<property name="current_session_context_class">thread</property>


<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>


<property name="show_sql">true</property>


<property name="hbm2ddl.auto"></property>

<mapping resource="com/ocr/wms/hib/mapping/HiberTableMapping.hbm.xml" />
<mapping resource="com/ocr/wms/hib/mapping/HiberTableSecondMapping.hbm.xml" />
<mapping resource="com/ocr/wms/hib/mapping/HibernateTableCompositeMapping.hbm.xml" />

</session-factory>

</hibernate-configuration>

Code calling Session factory using JNDI lookup
try {

Context ctx = new InitialContext();
SessionFactory sesionf = (SessionFactory) ctx.lookup("SessionFactory");
Session session = sesionf.getCurrentSession();
session.beginTransaction();
query="from HiberTableSecond hts where hts.serialid = any(select ht.id from HiberTable ht)";
List sourcelist = session.createQuery(query).list();
return sourcelist;
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}

This is the Full stack trace of the exception that occured:

Hi,

Have you bind the SessionFactory into JNDI ? You have to bind the SessionFactory first to the JNDI.

Into the jboss server you can do this using the Hibernate MBean service. This service take care of building your Configuration and SessionFactory object and also to bind the SessionFactory into the server JNDI.

I guess into the WebSphere is also some kind of process but I am not very sure about this.
I am using JBoss.

I hope this help.
Calin.

The hibernate configuration file must be loaded first. So have that in the static block of the class or have a start up class with the below.

For say in HibernateUtil.java have the below

static {
try {
// Create the SessionFactory from hibernate.cfg.xml
new Configuration().configure("com/../hibernate.cfg.xml").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);
}
}
