Trouble with getDirectoryProviders

Hello,

I'm having some problems with getDirectoryProviders returning null. I'm using Hibernate Search 3.2.0 Final running on JBoss 6.0 M3.

Sample code: (Scala)

Code:

   private val entityManager = Search.getFullTextEntityManager(em)
   val searchFactory = entityManager.getSearchFactory()      
   val provider = searchFactory.getDirectoryProviders(entityClass)(0)

My config in persistence.xml:

Code:

<property name="hibernate.search.default.directory_provider" value="org.hibernate.search.store.FSDirectoryProvider"/> 
<property name="hibernate.search.default.indexBase" value="C:\search"/> 

The third line above returns a NullPointerException when trying to access the first array element.

Any ideas appreciated!
Greg

you're sure entityClass is indexed (annotated)?

Here's a clip from the entity class. I removed a lot of other fields (many of which have relationships/joins), but for testing only one non-joined field is annotated for indexing.

Code:

@Entity
@Table(name = "AV_T_PART_CATEGORY")
@Indexed
public class AvTPartCategory implements java.io.Serializable {
   public static final long serialVersionUID = -1;
   private Long partCtgrId;
   private String partCtgrName;

   // Transient attributes
   @Transient
   private String indexTimestamp;

   public AvTPartCategory() {
   }

   @Id
   @Column(name = "PART_CTGR_ID", nullable = false, precision = 22, scale = 0)
   @NotNull
   public Long getPartCtgrId() {
      return this.partCtgrId;
   }

   public void setPartCtgrId(Long partCtgrId) {
      this.partCtgrId = partCtgrId;
   }

   @Column(name = "PART_CTGR_NAME", nullable = false, length = 80)
   @NotNull
   @Length(max = 80)
   @Field(index = Index.UN_TOKENIZED, store = Store.YES)
   public String getPartCtgrName() {
      return this.partCtgrName;
   }

   public void setPartCtgrName(String partCtgrName) {
      this.partCtgrName = partCtgrName;
   }
}

Is there anything obviously wrong with this code? Any known issues w/Hibernate Search and JBoss 6.0.0.M3?

Thanks,
Greg

you're sure that searchFactory!=null ?

could you provide a testcase or a minimal sample app I could run?

That's a very kind offer but I'm not really sure how to section a chunk off into something "portable".

I did do some further research and tracing. My searchFactory is non-null but the list of directory providers is null. Back-tracing the code through SearchFactoryImpl.initDocumentBuilders I discovered that there are no class mappings in the SearchConfiguration object. Tracing a bit further back it would seem these class mappings originate from Hibernate someplace, so this is likely a Hibernate configuration issue somewhere that is causing problems for Search. Hibernate is not picking up my annotated entity classes for some reason.

This isn't going to be fun...
