Hi,

im tryin' to index an object which has attributes of class a, b, and c, something like:
Code:
@indexed
@entity
class topclass(){

   @IndexedEmbedded
   A instanceA = null;
   @IndexedEmbedded
   B instanceB = null;
   @IndexedEmbedded
   Set<C> setOfC = null;
   ...
}


A and B been indexed correctly, but theres no index created for class C. Anybody could tell me why?

Thx.

(edit: still using hs 3.0.1)

What do you mean with "there is no index created for this class"? Like a physical index on the file system. If the embedded entity is not itself annotated with @Indexed there won't be an additional index directory.
Or do you mean the entities are not searchable? Have you inspected the index for TopClass with Luke? In case the Lucene Documents really don't contain any information for class C it would help if you post the code for your annotated entities together with the code on how you index them and how you try to search. Just looking at the generic usecase you are describing it should work.

The entities are not searchable. Luke doesnt offer me the fields of C if i inspect the index of topclass.
The point is, C is just an interface, which some other classes (annotated as @Entity) are implementing.
I index the classes the following way:
Code:
fSession.beginTransaction();
List<topclass> topList = dbSession.createCriteria(topclass.class).list();
for(topclass tc : topList){
   fSession.index(tc);
}
fSession.getTransaction().commit();
fSession.close();


Am i missing something about the interface issue?

Can you show/post the annotated classes?

topclass:
Code:
@Indexed
@Entity
public abstract class topclass implements Serializable {

   @DocumentId
   private Integer      id            = null;

        @IndexedEmbedded
        private A someA                                  = null;
        @IndexEmbedded
        private B someB                                   = null;
         ....
   @IndexedEmbedded
   private Set<C>      notizen      = new HashSet<C>();
        ...

interface C:
Code:
@Entity
public interface C {
   @DocumentId
   public Integer getId();
   @Field
   public String getText();
        ...

class implementing C:
Code:
@Indexed
@Entity
public abstract class someOtherClass implements C, Serializable {

   private static final long serialVersionUID = 1L;
   
   @DocumentId
   private Integer id = null;
   @Field(index=Index.UN_TOKENIZED, store=Store.YES)
   private String text = null;
        ...

class extending someOtherClass:
Code:
@Entity
public class someFinalClass extends someOtherClass {

   private static final long serialVersionUID = 1L;

   @IndexedEmbedded
   private someAttrib sab = null;
        ...

if i remember correctly, the interface implementing class did contain a reference to the class it was instanciated in. So i had to made use of the "@ContainedIn" annotation.
But its long ago i did that, not sure if it was exactly that one, sorry.
