duplicate import error

I'm using hibernate 2.1 with Tomcat and everytime I put "class" in one-to-many or many-to-one tags, I get an hibernate error about duplicate import !

Here is my mapping file :

Code:

<hibernate-mapping package="mypackage">

    <class name="SupportClient" table="SupportClient">

        <id name="numeroSupport" type="int">
            <column name="numerosupport" sql-type="smallint" not-null="true"/>
            <generator class="uuid.hex"/>
        </id>
        
        <property name="numeroClient"  type="int">
            <column name="numeroclient" sql-type="smallint"/>
        </property>

        <property name="numeroDevis"  type="int">
            <column name="numerodevis" sql-type="smallint"/>
        </property>
        
        <property name="observation"  type="string">
            <column name="observation" sql-type="varchar(255)"/>
        </property>
        
        <many-to-one name="typeSupport" column="support"/>

        <set name="fichiersClient" inverse="true" lazy="true">
           <key column="numerosupport"/>
           <one-to-many class="FichierClient"/>
        </set>
    </class>
    
    <class name="TypeSupport" table="TypeSupport">

        <id name="code" type="int">
            <column name="codetypesupport" sql-type="smallint" not-null="true"/>
            <generator class="native"/>
        </id>
        
        <property name="designation"  type="string">
            <column name="libelletypesupport" sql-type="varchar(50)"/>
        </property>
        
    </class>

    <class name="FichierClient" table="FichierClient">

        <id name="code" type="varchar(32)">
            <column name="id" sql-type="varchar(32)" not-null="true"/>
            <generator class="native"/>
        </id>
        
       <many-to-one name="numeroSupport" column="numerosupport"/>
        
        <property name="nom"  type="string">
            <column name="nomfichier" sql-type="varchar(150)"/>
        </property>
        
    </class>

</hibernate-mapping>

The error is :

Code:

duplicate import : SupportClient

Check the previous logs, you'll find some better infos

I use an HibernateUtil class, and I was loading configuration from an XML configuration file. It seems that it's better to use something like that :

Code:

...

Properties propsSupport = new Properties();
propsSupport.setProperty("hibernate.connection.datasource", java:comp/env/jdbc/support");
propsSupport.setProperty("hibernate.show_sql", "false");
propsSupport.setProperty("hibernate.dialect", net.sf.hibernate.dialect.SQLServerDialect");
propsSupport.setProperty("hibernate.jdbc.batch_size", "10");

Configuration cfgSupport = new Configuration()
                                  
.addClass(mypackage.SupportClient.class)
                                  
.addClass(mypackage.TypeSupport.class)
                                  
.addClass(mypackage.FichierClient.class)
                                  
.addClass(mypackage.CommandeClient.class)
                                  
.setProperties(propsSupport);
sessionFactorySupport =cfgSupport.buildSessionFactory();
...

by using this way of configuration, duplicate import error has disappeared. Before I used something like that :

Code:

...

URL configFileURLWorkplan = HibernateUtil.class.getResource("hibernateSupport.cfg.xml");
sessionFactoryWorkplan = new Configuration().configure(configFileURLSupport).buildSessionFactory();
...

Thne you really had duplicate lines in your mapping file
