Bonjour,
Je suis débutant avec Hibernate et je suis entrain d'essayer de créer une couche d'accès aux données avec ce dernier, cependant je rencontre de nombreuses difficultés,...
Pour faire vite, le contenu de mon fichier cfg est comme tel:
Code:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory >
<!-- local connection properties -->
<property name="hibernate.connection.url">jdbc:oracle:thin:@egp-sdlainpa1:1521:XE</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.username">dih</property>
<property name="hibernate.connection.password">i2b2-2402</property>
<!-- property name="hibernate.connection.pool_size"></property -->
<!-- dialect for Oracle (any version) -->
<property name="dialect">org.hibernate.dialect.OracleDialect</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
<mapping resource="ObservationFact.hbm.xml"/>
<mapping resource="VisitDimension.hbm.xml"/>
<mapping resource="ProviderDimension.hbm.xml"/>
<mapping resource="PatientDimension.hbm.xml"/>
<mapping resource="ConceptDimension.hbm.xml"/>
</session-factory>
</hibernate-configuration>
et voici le contenu de l'un de mes fichiers de mapping
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

</class>
</hibernate-mapping>
j'ai une clé primaire composée et qui comporte des clés étrangères !!!
le message d'erreur est comme tel:
