I'm currently facing a problem while using composite-element with Hibernate.
I define a composite-element within the class greco.model.to.Masque. ( i.e field masqueChamps ).
When i try to save a Masque object , a " net.sf.hibernate.MappingException: No persister for: greco.model.to.MasqueChamps " exception is thrown.
My composite-element is not mapped explicitely as It seems that hibernate handle it for me .
After reading completely the hibernate reference documentation, and learning the samples provided in this document, I lack information about the use of composite-element.
- Does mapping a composite-element require mapping the composite-element in a separate class or composite-element are mapped implicitely ?
- Does anybody could provide me with a working example of composite-element ?
Any help would be great
Regards
Yann
PS : Related document ( mapping, debug stack ) concerning my problem are included at the end of this post.
Hibernate version: 2.1.4
Mapping documents:
Code:
<class
name="greco.model.to.Masque"
table="MASQUE"
>
...
<set
name="masquesChamps"
table="MASQUECHAMPS"
lazy="true"
cascade="all-delete-orphan" >
<key>
<column name="ID_MASQUE" />
</key>
<composite-element class="greco.model.to.MasqueChamps">
<property name="rangChampsAffiche" type="java.lang.Integer" column="RANGCHAMPSAFFICHE"/>
<property name="timestamp" type="long" column="TIMESTAMP"/>
<many-to-one name="champ" column="ID_CHAMPS" class="greco.model.to.ChampsAffiche"/>
</composite-element>
</set>
</class>
