Hibernate - createQuery problems

Question

Hi!
I'm getting this exception and can't locate what is wrong:
org.hibernate.QueryException: ClassNotFoundException: org.hibernate.hql.ast.HqlToken [from com.test.model.User where userId = ?]

     javax.servlet.http.HttpServlet.service(HttpServlet.java:803)My mapping file looks like this:

<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.redbet.model">
     <class name="User" table="users">
          <id name="userId" column="userId">
               <generator class="increment" />
          </id>
          <property name="username" column="username" />
     </class>
</hibernate-mapping>And i have put the hibernate and antlr jar files in the lib directory, this is the code that fails, it fails on session.createQuery
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
User result = (User) session.createQuery( "from User where userId = ?" ).setInteger( 0, userId ).uniqueResult();
session.getTransaction().commit();The code for hibernateUtil looks like this:
static {
     try {
          InputStream in = Thread.currentThread().getContextClassLoader().getResourceAsStream( "hibernate.cfg.xml" );
          Configuration configuration = new Configuration().addInputStream( in ).configure();
          sessionFactory = configuration.buildSessionFactory();
     } catch( Throwable ex ) {
          LOG.fatal( "Could not create session factory: " + ex.getMessage() );
          throw new ExceptionInInitializerError( ex );
public static SessionFactory getSessionFactory() {
     return sessionFactory;
}

Okay it might be that you could have placed few similar files in your
%CATLINA_HOME%\common\libfor quest of sharing the SessionFactory Object at container level is that it ??
If,it is so first remove respective libraries from their and do not try that.Ensure the basic things goes in the right-way.
hibernate-cfg.xml
=================
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD//EN"

<hibernate-configuration>

     <property name="connection.driver_class"><!--DRIVER--></property>
     <property name="connection.url"><!--JDBCURL--></property>

     <mapping resource="com/test/model/User.hbm.xml" />
  </session-factory>
</hibernate-configuration>HibernateUtils
static {
     try {
                //As the Configuration would automatically check for hibernate-cfg.xml
          Configuration configuration = new Configuration().configure();
                /*please refer http://www.hibernate.org/hib_docs/v3/api/org/hibernate/cfg/Configuration.html#configure()*/
          sessionFactory = configuration.buildSessionFactory();
     } catch( Throwable ex ) {
          LOG.fatal( "Could not create session factory: "+ ex.getMessage() );
          throw new ExceptionInInitializerError( ex );
public static SessionFactory getSessionFactory() {
     return sessionFactory;
}Other than this when i was going through your set of libraries i found that you might using POSTGRESQL-8.2.
And i don't think its been tested over Hibernate platform either.
Please refer. http://www.hibernate.org/80.html
and one more thing i can see that you are using Spring specific libraries as well spring itself provides its own implementation to use hibernate.it could easily be configured and used easily few utility classes(HibernateDAOSupport is one such class which you might of using).
How about trying it instead of re-inventing the wheel by creating your own Utility class ??
if all these don't help i'd advice you go ahead with hibernate/spring forums.
Hope that makes some sense.
REGARDS,
