When asking questions, give at least:
the Hibernate version
your mapping documents
the Java code between sessionFactory.openSession() and session.close()
the full stack trace of any exception that occurs
the name and version of the database you are using
a debug level Hibernate log excerpt is also appreciated

Ok! here it go:

Hibernate 2.1

Database Firebird 1.5

Mapping document
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping
    PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd"><hibernate-mapping>
   <!--Mapeamento do Objeto Usuario-->
    <class name="objetos.pessoa.Usuario"
           table="USUARIO">

      <!--Primary Key-->
        <id name="idUsuario" type="integer">
            <column name="IDUSUARIO" sql-type="integer" not-null="true"/>
            <generator class="assigned"/>           
        </id>
       
        <!-- Fields -->
        <property name="nome">
            <column name="NOME" sql-type="char(32)"
                    not-null="false"/>
        </property>
    </class>
</hibernate-mapping>


Code before opensession:
Code:
InitialContext ic = new InitialContext();
SessionFactory factory = (SessionFactory)ic.lookup("java:/hibernate/HibernateFactory");
session = factory.openSession();
