Hi,
I want to map a simple class hierarchy that consists of two classes at the moment: Person and Lodger. Lodger is inherited from Person.
I want to use table per subclass with mapping files. Do I need a own mapping file for the class Lodger? My mapping file for Person looks like this:
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping default-lazy="false" auto-import="false">
<class name="de.waldhausweg7.model.Person" table="Person">
<id name="personId" type="int">
<generator class="increment" />
</id>
<property name="firstName" column="firstName" />
<property name="surName" column="surName" />
<property name="street" column="street" />
<property name="extraAddressLine" column="extraAddressLine" />
<property name="phone" column="phone" />
<property name="mobile" column="mobile" />
<property name="fax" column="fax" />
<property name="email" column="email" />
<property name="comment" column="comment" />
<!-- 1:n-Beziehung zu Ort -->
<many-to-one name="city" column="cityId" class="de.waldhausweg7.model.City" />
<!-- n:m-Beziehung zu Kategorie -->
<set name="categories" table="person_category" lazy="false">
<key column="personId" />
<many-to-many class="de.waldhausweg7.model.Category" column="categoryId" />
</set>
<!-- Beziehung zu Unterklasse Lodger -->
<joined-subclass name="de.waldhausweg7.model.Lodger" table="lodger">
<key column="personId" />
<property name="gender" column="gender" />
</joined-subclass>
</class>
</hibernate-mapping>
I created a mapping file for Lodger:
Code:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping default-lazy="false" auto-import="false">
<class name="de.waldhausweg7.model.Category" table="Category">
<id name="lodgerId" type="int">
<generator class="foreign" />
</id>
<property name="gender" column="gender" />
</class>
</hibernate-mapping>
The lodger-Table contains a field called lodgerId as primary key.
But it does not work.
This is the error (I use Hibernate with IceFaces):
