Hi experts
I want to insert some Data in a Collection in MongoDB. I want to index this Data, If I put @Indexed at the top of my entity class, I get this exception:
Code:

my entity class:
Code:
@Entity
@Indexed
public class User{
@Id
@GeneratedValue(generator = "uuid")
private String id;
@Field(index= Index.YES,analyze = Analyze.NO,store = Store.NO)
private String city;
@Field(index= Index.YES, analyze = Analyze.NO)
private int UserID;
and the DAO:
Code:
String[] city={"Berlin","Shiraz","Chemnitz","Teheran","Stutgart","Görlitz",
"Münster","Köln","Isfahan","Losangles","Washington","Paris","Madrid","London",
"Newyork","Sydny","Cairo","Amsterdam","Aachen","Hamburg","Dresden","Leipzig",
"Montreal","Vancouver","Prag","München","Isfahan"};
OgmConfiguration cfgogm=new OgmConfiguration();
cfgogm.configure("hibernate.cfg.xml");
serviceregistry=new ServiceRegistryBuilder().applySettings(cfgogm.getProperties()).buildServiceRegistry();
sessionfactory=cfgogm.buildSessionFactory(serviceregistry);
Session session=sessionfactory.getCurrentSession();
session.beginTransaction();
for(int i=0;i<3;i++)
{
//session.beginTransaction();
Random rd=new Random();
int c=rd.nextInt(27)+0;
int id=rd.nextInt(100000)+10000;
User user=new User();
user.setCity(city[c]);
user.setUserID(id);
session.save(user);
}
session.flush();
session.getTransaction().commit();
System.out.println("Done...");
}
What should I do to solve this exception?
