Hi

I am new to hibernate so my question is probably not that interesting. Anyway I couldn't find a solution to my problem in the forum.

My table in the DB uses a own column with automatically assigned GUIDS.
I tried following but it doesn't work.

Thank you very much

Code:

Initial SessionFactory creation failed.org.hibernate.MappingException: Could not determine type for: guid, for columns: [org.hibernate.mapping.Column(GUIDModulID)]

         <generator class="guid"></generator>
      </id>
      <property name="Name"> <column name="ModulBezeichnung"></column></property>
   </class>
</hibernate-mapping>

Code:

package verwaltung;
import org.hibernate.id.GUIDGenerator;

public class Modul {

   private GUIDGenerator id;
   
   private String fName;
   
   public Modul(){}

   public String getName() {
      return fName;
   }

   public void setName(String name) {
      fName = name;
   }

   public GUIDGenerator getId() {
      return id;
   }

   private void setId(GUIDGenerator id) {
      this.id = id;
   };
   
}

Should be String id, not that GUIDGenerator

String id;

public String getId(){ return id;}
public void setId(String v ){ id = v;}
