Hi! I´m using Eclipse 3.4 and Hibernate tools 3.2.4 for Eclipse.
Oracle 9i. Tomcat 6 (stable).


The problem I get is about JNDI resource.


I use reverse ingeniering to generate cfg.xml and I run "Hibernate Code Generation". The results are those:

The code which has the problem:

import java.util.List;
import javax.naming.InitialContext;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.hibernate.LockMode;
import org.hibernate.SessionFactory;
import static org.hibernate.criterion.Example.create;

/**
* Home object for domain model class CategoriasT.
* @see eu.malaga.dao.hibernate.CategoriasT
* @author Hibernate Tools
*/
public class CategoriasTHome {

private static final Log log = LogFactory.getLog(CategoriasTHome.class);

private final SessionFactory sessionFactory = getSessionFactory();

protected SessionFactory getSessionFactory() {
try {
return (SessionFactory) new InitialContext()
.lookup("SessionFactory");
} catch (Exception e) {
log.error("Could not locate SessionFactory in JNDI", e);
throw new IllegalStateException(
"Could not locate SessionFactory in JNDI");
}
}










hibernate.cfg.xml:
<?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>
<property name="hibernate.bytecode.use_reflection_optimizer">false</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.OracleDriver</property>
<property name="hibernate.connection.password">TEMAWEB_USR</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@<myHost>:1521:dbd3</property>
<property name="hibernate.connection.username">TEMAWEB_USR</property>
<property name="hibernate.default_schema">TEMAWEB</property>
<property name="hibernate.dialect">org.hibernate.dialect.Oracle9iDialect</property>
<mapping resource="eu/malaga/dao/hibernate/TemasT.hbm.xml" />
<mapping resource="eu/malaga/dao/hibernate/CategoriasT.hbm.xml" />
</session-factory>
</hibernate-configuration>

Tables "Temas" and "Categorias" are completally indepent and very simple. I´m trying to use just "Categorias".

I write the following code at the jsp:

<%
CategoriasT categoria1 = new CategoriasT();
CategoriasTId categoriaId1 = new CategoriasTId();
categoriaId1.setIdAplicacion("testDavidApl_1");
categoriaId1.setIdCategoria("testDavidCat_1");
categoria1.setId(categoriaId1);

CategoriasTHome cat = new CategoriasTHome();
cat.attachClean(categoria1);
%>

The problem I get is about JNDI resource:

Do I have to define any JNDI element?
How and where do I define it?
Do I have to include any library at Tomcat lib?
At the eclipse project a have include de jdbc driver.

Thanks a lot.

Hi, I have a same problem with you.

But I used the Junit to test it, and use this code to get session. It works!


Code:
Configuration cfg = new Configuration();
session = cfg.configure().buildSessionFactory().openSession();


If you resolved the problem, could you please send me a message?

Did someone could successfully solve this issue?

I have the very same issue with Eclipse auto-generated code.
