Please, provide the sample and the way we need to configure Hibernate. Note, that using this snippet doesn't work, it throws exception:

<?xml version="1.0"?>
<hibernate-mapping xmlns="http://www.hibernate.org/xsd/hibernate-mapping"
                   xsi:schemaLocation="http://www.hibernate.org/xsd/hibernate-mapping hibernate-mapping-4.0.xsd"

                   package="org.blah.blah">
<class name="Book" table="book">
    <id name="id">
      <generator class="native"/>
    </id>
    <property name="title"/>
  </class>
</hibernate-mapping>
