I have a structure which contains two classes.... each defining a @OneToMany association to a common class (SaleItem).
The following association is shown below:
Sale -----< SaleItem >------- ItemDescription
class SaleItem contains this association:
Code:
@ManyToOne
@JoinColumn(name="description_id", insertable=false, updatable=false, nullable=false)
public ItemDescription getDescription() {
return description;
}
@ManyToOne
@JoinColumn(name="sale_id", insertable=false, updatable=false, nullable=false)
public Sale getSale() {
return sale;
}
for class Sale:
Code:
@OneToMany(cascade=CascadeType.ALL)
@JoinColumn(name="sale_id", nullable=false)
@org.hibernate.annotations.IndexColumn(name="sposition")
@org.hibernate.annotations.Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
public List<SaleItem> getSaleItems() {
return saleItems;
}
for class ItemDescription:
Code:
@OneToMany(cascade=CascadeType.ALL)
@JoinColumn(name="description_id", nullable=false)
@org.hibernate.annotations.IndexColumn(name="idposition")
@org.hibernate.annotations.Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
public List<SaleItem> getSaleItems() {
return saleItems;
}
When I tried to execute my application, it throws up the error:
Code:
