Hi all,

I am experiencing troubles with hibernate and I look into the the log and have a mysterious message, but I cannot understand it. Do you have any idea ? Thanks for your help.

Hibernate version: 3.1

Mapping documents:

<hibernate-mapping package="com.pf.projet.data.articlebis.modele">

<typedef name="formatCharType"
class="com.pf.projet.data.articlebis.util.FormatCharType">
<param name="nbChar">10</param>
</typedef>

<class name="TableRef" table="T_TABREF_REF" >

<comment>Table de reference.</comment>

<composite-id name="id" class="TableRef$Id" >
<key-property name="cotab" />
<key-property name="covlr"/>
</composite-id>


<discriminator column="cotab" type="string" insert="false" />
<property name="lbvlr" />
<property name="noord"/>


</class>

</hibernate-mapping>

Full stack trace of any exception that occurs:
org.hibernate.MappingException: Following superclasses referenced in extends not found: com.pf.projet.data.articlebis.modele.TableRef[com.pf.projet.data.articlebis.modele.suitede],com.pf.projet.data.articlebis.modele.TableRef[com.pf.projet.data.articlebis.modele.suitede],com.pf.projet.data.articlebis.modele.TableRef[com.pf.projet.data.articlebis.modele.general],com.pf.projet.data.articlebis.modele.TableRef[com.pf.projet.data.articlebis.modele.general],com.pf.projet.data.articlebis.modele.TableRef[com.pf.projet.data.articlebis.modele.commercial],com.pf.projet.data.articlebis.modele.TableRef[com.pf.projet.data.articlebis.modele.general],com.pf.projet.data.articlebis.modele.TableRef[com.pf.projet.data.articlebis.modele.logistique],com.pf.projet.data.articlebis.modele.TableRef[com.pf.projet.data.articlebis.modele.general],com.pf.projet.data.articlebis.modele.TableRef[com.pf.projet.data.articlebis.modele.general],com.pf.projet.data.articlebis.modele.TableRef[com.pf.projet.data.articlebis.modele.general]

Name and version of the database you are using:
I am using Oracle

where are your subclass tags?

Thanks for answering. There are many subclasses to Table ref. But here is a typical subclass mapping of it.

I dont know what should be the normal display but only the package name is displayed in my error message, not the class name.

<hibernate-mapping package="com.pf.projet.data.article.modele.logistique" >

<typedef name="formatCharType"
class="com.pf.projet.data.article.util.FormatCharType">
<param name="nbChar">10</param>
</typedef>

<subclass name="TypeOuverture" extends="com.pf.projet.data.article.modele.TableRef" discriminator-value="TYOUVCOD" />

</hibernate-mapping>

It looks like a bug in Hibernate, getting confused with the package tag in the subclasses hbm files.

Try getting rid of the package declaration. Something like this:

I finally understand that the message "Following superclasses referenced in extends not found" was refering to the mapping definition and not the classes.

The thing was I did not had mapped the TableRef.hbm.xml in the hibernate.cfg.xml.

Basic, but the pessage was a little confusing.


Thanks for your helps.
