To Whom It May Concern:

I am using hibernate3.jar, Tomcat 5.5, Microsoft SQL 2000. I got the error
java.lang.NoClassDefFoundError: antlr/ANTLRException
when I ran the following code:

package com.oreilly.hh;

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


import java.sql.Time;
import java.util.Date;

/**
* Create sample data, letting Hibernate persist it for us.
*/
public class CreateTest {

public static void main(String args[]) throws Exception {
// Create a configuration based on the properties file we've put
// in the standard place.
Configuration config = new Configuration();

// Tell it about the classes we want mapped, taking advantage of
// the way we've named their mapping documents.
config.addClass(Track.class);

// Get the session factory we can use for persistence
SessionFactory sessionFactory = config.buildSessionFactory();

// 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
tx = session.beginTransaction();

Track track = new Track("Russian Trance",
"vol2/album610/track02.mp3",
Time.valueOf("00:03:30"), new Date(),
(short)0);
session.save(track);

track = new Track("Video Killed the Radio Star",
"vol2/album611/track12.mp3",
Time.valueOf("00:03:49"), new Date(),
(short)0);
session.save(track);


track = new Track("Gravity's Angel",
"vol2/album175/track03.mp3",
Time.valueOf("00:06:06"), new Date(),
(short)0);
session.save(track);

// 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 e;
} finally {
// No matter what, close the session
session.close();
}

// Clean up after ourselves
sessionFactory.close();
}
}


I was trying to convert hibernate 2 java code to hibernate 3.

Here is my hibernate.properties file:
hibernate.dialect=org.hibernate.dialect.SQLServerDialect
hibernate.connection.driver_class=net.sourceforge.jtds.jdbc.Driver
hibernate.connection.url=jdbc:jtds:sqlserver://al:1433/Albert
hibernate.connection.username=sa
hibernate.connection.password=mychau1

Can anybody please give me a hint why I am getting the above error.

Thank You.

Yours,

Desperate.

Hibernate has a number of dependencies. They're jars that need to be available on the classpath when you run your app. See this: Chapter 1. Introduction to Hibernate
