मैं एच 2 डेटाबेस के साथ जेबॉस एएस 7 का उपयोग कर रहा हूं। मेरे पास एक स्टैंडअलोन एप्लिकेशन है जो इस तरह के डेटाबेस से कनेक्ट करने का प्रयास करता है।हाइबरनेट फेंकता है org.hibernate.persister.entity.SingleTableEntityPersister

मेरे इकाई वर्गों:
public class Kunde {
long id;
String vorname;
String nachname;
String firma;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getVorname() {
return vorname;
}
public void setVorname(String vorname) {
this.vorname = vorname;
}
public String getNachname() {
return nachname;

public void setNachname(String nachname) {
this.nachname = nachname;
}
public String getFirma() {
return firma;
}
public void setFirma(String firma) {

}
}
(एक दूसरे को समान दिखता है)।
मेरे परीक्षण कोड:
public static void main(String[] args) {
try {
// This step will read hibernate.cfg.xml and prepare hibernate for
// use
Configuration configuration = new Configuration();
configuration.configure();
ServiceRegistry serviceRegistry = new ServiceRegistryBuilder()
.applySettings(configuration.getProperties())
.buildServiceRegistry();
SessionFactory sessionFactory = configuration
.buildSessionFactory(serviceRegistry);
Session session = sessionFactory.openSession();
// Create new instance of Kinde and set values in it by reading them
// from form object
System.out.println("Inserting Record");
Kunde kunde = new Kunde();
kunde.setId(1);
kunde.setVorname("A");
kunde.setNachname("N");
kunde.setFirma("Privat");
session.save(kunde);
System.out.println("Done");
// Actual insertion will happen at this step
session.flush();
session.close();
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
