Hi,

I'm new to hibernate and need som advice.

I'm using NetBean 6.8, running hibernate against Oracle. I'm able to connect to Oracle instance from NB (i.e I can 'browse the tables'). FYI the Oracle instance reside on a virtual server with a different host id.

Hibernate has been configured according to the instructions in the NB hibernate tutorial and the provided sample exercise worked. However trying a similar example myself, fails.

I've tried the following class:

public class CreateTest {


public static void main(String args[]) throws Exception {
// Create a configuration based on the XML file we've put
// in the standard place.
System.out.println("h0");
Configuration config = new Configuration();
System.out.println("h1");
config.configure();
System.out.println("h2");
// Get the session factory we can use for persistence
SessionFactory sessionFactory = config.buildSessionFactory();
System.out.println("h3");
// Ask for a session using the JDBC information we've configured
Session session = sessionFactory.openSession();

Transaction tx = null;

try {
// Create some data and persist it
long id = 111;

tx = session.beginTransaction();
Items items = new Items(id,"12345","item_name","A","In Work","NEW","23456","doc name","A","NEW","2010-01-02");

System.out.println("Howdy ...");

session.save(items);
// We're done; make our changes permanent
tx.commit();
} catch (Exception e) {
if (tx != null) {
// Something went wrong; discard all partial changes
tx.rollback();
}
throw new Exception("Transaction failed", e);
} finally {
// No matter what, close the session
session.close();
}
// Clean up after ourselves
sessionFactory.close();
}

Running this class results in the following error:

Java Result: 1

So, as you can see, the code never gets pass 'SessionFactory sessionFactory = config.buildSessionFactory();'

Here is the hibernate config 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>
<property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@vmserver.ecc.com:1521:wind</property>
<property name="hibernate.connection.username">erp</property>
<property name="hibernate.connection.password">erp</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.current_session_context_class">thread</property>
<mapping resource="ext/ecc/erp/data/Structure.hbm.xml"/>
<mapping resource="ext/ecc/erp/data/items.hbm.xml"/>
</session-factory>
</hibernate-configuration>

Any ideas why this happens?

Cheers ...
