Davranış Web Kapsayıcısını her yeniden başlattığımda, her şey birkaç dakika boyunca çalışır ve bu hata atılır. Neyi kaçırıyorum?
DÜZENLEME:
Şimdi de uygulama kapsamına bir varlık kullanabilir ve aynı hata Ülke biriminin oluşur. Kullanıcı ve Ülke, persistance.xml dosyasında sınıflar olarak tanımlanır. Ayrıca, hariç tutulan listelenmemiş sınıflar false değerine ayarlanır.

İKİNCİ DÜZENLEME: Mevcut davranışa dayanarak o web konteyner başlar görünüyor ve ilk sıcak dağıtım kadar iyi çalışır.
Netbeans'i kullandığınıza bahse girerim? Muhtemelen ilgili: http://wiki.eclipse.org/EclipseLink/Development/JPA_2.0/metamodel_api#DI_101:_20100218:_Descriptor.javaClass_is_null_on_a_container_EM_for_a_specific_case – BalusC
Eclipse Indigo Service Release 1 kullanıyorum ama bu aldığım tam bir hata. – TGM
Emin değilim. İşlem türünü JTA'ya ayarlamayı denediniz mi? Aynı zamanda bir Java EE web uygulamasında en mantıklı seçimdir (aksi halde, başlangıç, işleme ve geri alma işlemleri için çok sayıda çirkin yazılım kodu yazmanız/kopyalamanız gerekir). Son stacktrace'iniz de bir "statik" başlatıcı bloğu içinde JPA işini yaptığınızı söyler. Bu teoride iyi çalışır, ancak bir enerji verimliliği ortamında bu kötü bir fikirdir. Bunun yerine bir uygulama scoped fasulye bir (post) yapıcıda yapın. – BalusC
