Hi all !!

I've a very very boring problem...

Environnement.hbm.xml is like that :

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">

<hibernate-mapping>
<class name="majpps.beans.Environnement" table="environnement" lazy="true">
<id name="idEnv" column="IDENV">
<generator class="sequence">
<param name="seq_environnement">seq_environnement</param>
</generator>
</id>

<property name="nom">
<column name="NOM" sql-type="VARCHAR2(50)" not-null="true"/>
</property>

<discriminator column="ENV_TYPE" type="string"/>

<subclass name="majpps.beans.EnvironnementPoste" lazy="false" discriminator-value="POSTE"
dynamic-update="true" dynamic-insert="true">
<property name="version">
<column name="VERSION" sql-type="VARCHAR2(50)" not-null="true"/>
</property>
</subclass>

<subclass name="majpps.beans.SolutionLecteur" lazy="false" discriminator-value="LECTEUR"
dynamic-update="true" dynamic-insert="true"/>

</class>

</hibernate-mapping>

What's the prob folks please ?? I don't understand... right DTD, right tags... don't really understand and I'm tired of this issue...

Really Thank You !!! Really...

have you tried "cutting" discriminator + subclasses declaration?
just to test.

Another idea,
move <discriminator column="ENV_TYPE" type="string"/>
before the property declaration...

Ok, by moving the discriminator tag above property tags it works !! =)

But I have another error now... this one :

It's very boring somedays... somedays not... but today it's VERY VERY boring...

=(

Hey I've find the solution to my problem !! huh... I dunno if it's really the right solution but it works...

I've put Lazy="false" in the class tag...

Thanks folks !! =)

oh, of course if you declare lazy='true' in the class definition, that mean the proxy is the class... but you should read doc about this parameter to understand what it exactly do...
