Gwt ve Jpa ile uygulama geliştiriyorum. Customer, CustomerContact, CustomerTarget vb. daha birçok entity kullanarak çalışıyorum. Daha önce veritabanından bu entity yardımı ile istediğim verileri çekebiliyor, güncelleme yapabiliyordum. Müşterinin son bilgilerini geçici bir tabloda saklama ihtiyacı duydum ve bu nedenle CustomerTemp, CustomerContactTemp, CustomerTargetTemp vb. entity oluşturdum ve tabii ki bunların veritabanındaki karşılığı olan tabloları da oluşturdum. Entitylerin her birini birbiriyle ilişkilendirmeme ve persistence.xml dosyasına entityleri yazmama rağmen aşağıdaki hatayı alıyorum.

Burada bahsedilen hata neden kaynaklanabilir acaba?

ÇÖZÜM: Sorun FirmCustomerTemp.java'da kullandığım mappedBy'ın yanlış isimlendirilmesinden kaynaklanıyormuş. CustomerTargetTemp.java'da FirmCustomerTemp nesnesi için aşağıdaki gibi ilişki tanımladım:

@ManyToOne
@JoinColumn(name="TempFirmCustomerId")
private FirmCustomerTemp firmCustomerTemp;

FirmCustomerTemp'de ise ilişikiyi aşağıdaki gibi tanımladım sorun çözüldü:

@OneToMany(mappedBy="firmCustomerTemp", fetch=FetchType.LAZY, cascade=PERSIST)
private List<CustomerTargetTemp> customerTargetsTemp;

mappedBy içerisindeki değer, ilişkide bulunduğu nesnesinin kendisiyle eşleşen değeri ile aynı ifadeye sahip olmalıydı.

CRMConfirmationLogs sinifinida gösterebilir misin?

(16 Eyl '13, 01:35) mahmut_can ♦ mahmut_can's gravatar image

Aslında CRMConfirmationLogs sınıfı değil de ConfirmationLog sınıfı var. Kodların içine ekledim.

Merhaba,

Multiple writable mappings exist for the field [LGOLD.dbo.CRMConfirmationLogs.FirmCustomerId]. Only one may be defined as writable, all others must be specified read-only. Mapping: org.eclipse.persistence.mappings.OneToOneMapping[firmCustomer]

Stackoverflow da bir cözüm sunulmus.
