Hibernate version: 3
I have many-to-many reletationship between product and performer; I have mapped the table product twice: to BasicProduct and InactiveBasicProduct (that was not my idea - but others call the shots ;-)).
The mapping for InactiveBasicProduct works fine, if I don't add a set for my many-to-many relationship. If I add the set I get an exception seen below. Is this a problem, that the Mapping of BasicProduct already has a set for the many-to-many relationship to performer? Thx
Mapping documents:
Code:
<hibernate-mapping package="com.sonydadc.claudio.hibernate">
<class name="com.sonydadc.claudio.product.beans.InactiveBasicProduct" table="CLAUDIO_PRODUCT" where="active='N'">
<id name="id" column="PRODUCT_ID" type="string"/>
<property name="title" column="PRODUCT_TITLE" type="string" />
<set name="performers" table="CLAUDIO_PRODUCT_PERFORMER" lazy="true">
<key column="PRODUCT_ID" />
<many-to-many column="PERFORMER_ID" class="com.sonydadc.claudio.product.beans.Performer" />
</set>
</class>
</hibernate-mapping>
Code:
public class InactiveBasicProduct implements Serializable {
private static final long serialVersionUID = 8283608851397524224L;
private String id;
private String title;
private String author;
private Set performers;
/**
* @return Returns the id.
*/
public String getId() {
return id;
}
/**
* @param id The id to set.
*/
public void setId(String id) {
this.id = id;
}
/**
* @return Returns the performers.
*/
public Set getPerformers() {
return performers;
}
/**
* @param performers The performers to set.
*/
public void setPerformers(Set performers) {
this.performers = performers;
}
/**
* @return Returns the title.
*/
public String getTitle() {
return title;
}
/**
* @param title The title to set.
*/
public void setTitle(String title) {
this.title = title;
}
}
Code:
public class InactiveProductDAO extends HibernateDaoSupport implements IInactiveProductDAO {
public InactiveBasicProduct getInactiveProduct(String id) {
InactiveBasicProduct prod = (InactiveBasicProduct) this.getHibernateTemplate().get(InactiveBasicProduct.class,id);
return prod;
}
}
