Problem with @Transient fields while indexing using Lucene.

Hi

I have problem with fields marked as @Transient.

Please see the code below.
In Candidate Class..

Code:

@IndexedEmbedded
@Transient
@OneToMany(fetch= FetchType.LAZY )
@JoinTable(name="events", joinColumns = {@JoinColumn(name = "candidate_id")}, inverseJoinColumns = {@JoinColumn(name = "comment_id")})
    public List<Comments> getComments() {
        return comments;}
        
... //setter for the comments.

Comments.java........

Code:

@Entity
@Table(name = "comments")
@Indexed
public class Comments
{

   private String   commentId;
   private String   eventId;
   private String   comments;
   private Date   date;

   @Id
   @GeneratedValue(strategy = GenerationType.IDENTITY)
   @DocumentId 
   @Column(name = "comment_id")
   public String getCommentId()
   {
      return commentId;
   }

      
   @Column(name = "event_id")
   public String getEventId()
   {
      return eventId;
   }
      
   @Basic 
   @Column(name = "comments")
   @Field(index = Index.TOKENIZED, store = Store.YES)
   public String getComments()
   {
      return comments;
   }

//setters...   
   
}

If I DO NOT mark Comments as @Transient in Candidate.java, it saves 'comments' in DB properly, and gets indexed properly. but INSERTS few null columns in 'events' table.

------
If I mark Comments as @Transient, it inserts 'comments' as well as 'events' into DB properly but fails to index 'comments' in candidate index.

Could anybody please help me in solving this problem, I want 'comments' to be indexed and searched. as well as events table should get populated with correct data.

Thanks for looking!

what's "events table"? some parent entity?

You don't mean the other way around?

what's this "public String getEventId()" ? can't you map the objects properly referring to instances instead of to their keys?

yes it is.

Could you show that or explain the relation with the other entities?

I mean why

Code:

public String getEventId()

and not just

Code:

public Event getEvent()

?
It appears you are wiring entities by yourself instead of delegating Hibernate to this tasks; this way it's not possible to automagically detect relations.
