Hibernate version:3.2.3

Mapping documents:
hibernate.cfg.xml looks like this:

Code:

<?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>

      <!-- Database connection settings -->
      <property name="connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property>
      <property name="connection.url">jdbc:jtds:sqlserver://10.1.1.96/db_modelity_pension_bll;instance=SQLEXPRESS;charset=cp1255</property>
      <!-- property name="connection.url">jdbc:jtds:sqlserver://10.1.1.55/rating_model;charset=cp1255</property-->
      
      <property name="connection.username">pension</property>
      <property name="connection.password">123456</property>

      <!-- JDBC connection pool (use the built-in) -->
      <property name="connection.pool_size">1</property>

      <!-- SQL dialect -->
      <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>

      <!-- Enable Hibernate's automatic session context management -->

      <!-- Echo all executed SQL to stdout -->
      <property name="show_sql">true</property>
      <mapping resource="com/dal/orm/RatingModel.hbm.xml"/>
   </session-factory>

</hibernate-configuration>

RatingModel.hbm.xml looks like this:

Code:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

      <!-- property name="nameDvid" column="name_dvid"/-->

      <many-to-one name="currentView" class="com.blogic.ratingmodel.history.ModelRunView" column="current_view_map_id"/>
   </class>
</hibernate-mapping>

Code between sessionFactory.openSession() and session.close():
RatingModel class use HibernateLoadable interface
this loads the RatingModel object:

Code:

      HibernateUtil.beginTransaction();
      currentModel = 
         (RatingModel) HibernateUtil.load(RatingModel.class, modelId);
      currentModel.setLangId(langId);

and this is the function load of RatingModel class

Code:

   public void load() throws GeneralException
   {
      try
      {
      long start = System.currentTimeMillis();
      domainSet.setTargetAccountId(new Integer(SystemPreferences.getInstance().getValueByKeyword(RatingModelConstants.ALL_ASSETS_ACCOUNT_ID_KEYWORD)));
      thresholdSet.setTargetAccountId(targetAccountId);
      long startCreatHierarchy = System.currentTimeMillis();
      loadGroupHierarchy();
      long endCreatHierarchy = System.currentTimeMillis();
      loadProperties();
      loadIndicatorsHierarchy();
      squareRIndicator.load();
      long end = System.currentTimeMillis();
      if(resultsManager == null)
      {
         resultsManager = new ModelResultsManager();
      }
      isLoaded = true;
      }catch (Exception e) {
         e.printStackTrace();
      }
   }

Name and version of the database you are using:
