A while ago I started working on a Hib. search / Seam solution. Everything seemed to work nicelly as far as I got. I needed to drop that project for some time I now when I got back to I can't get the listeners up and running.

I've added the following to my persistence.xml:


Which I thought would be enough. No need for events or need to create a configuration instance in the code.

I get org.hibernate.HibernateException: Lucene event listener not initialized when I try to run the following:



I've got an entity with the @Indexed annotation and some @Field for testing.

It seems like the listeners are never initialized - the lucene index folder isn't created.

I've got the following jar files in my EAR:

* hibernate-annotations.jar
* hibernate-search.jar
* lucene-core-2.1.0.jar
* and a bunch of seam related stuff

The Hibernate and Lucene jars are registered in my application.xml file.

What am I missing out here?

maybe your missing hibernate-commons-annotations.jar

Thank you, it works like a charm now :-)

This is what I've done to make Hiberate Search to start indexing Seam stuff:

* Make sure you got the right versions of the jar-files in \jboss-4.0.5.GA\server\default\lib I had old hibernate files there, and needed to change them for new files. The compatibility matrix ( http://www.hibernate.org/6.html#A3 ) helped me.

* If you for some reason got the hiberate-all.jar file there - remove it

* Add the following files to your EAR: hibernate-search.jar, hibernate-commons-annotations.jar and lucene-core-2.1.0.jar and make sure to create references to them in application.xml

* Make changes to persistence.xml, add
<property name="hibernate.search.default.directory_provider" value="org.hibernate.search.store.FSDirectoryProvider"/>
<property name="hibernate.search.default.indexBase" value="C:\luceneIndex"/>
The folder wasn't created automatically for me, but after adding it myself, it worked nicelly.

* Add @Indexed and other annotations to your entities. Note! If you read the docs ( http://www.hibernate.org/hib_docs/searc ... figuration ) it says @Indexed(name="Status"), which is wrong. The correct syntax follows in the doc (@Indexed(index="Status"))

This is my experience and perhaps not the right way to, but it finally worked, perhaps this could be of help to someone else.

Nice,
Can you create a wiki page out of you experience. We plan to make HSearch work smoother with Seam but in the mean time...

Hi,

May I could get some help here. I tried to use Seam and Hibernate Search together but I couldn't get it to work. This is the Entity I am trying to index:


@Entity
@Name("user")
@Indexed(index="user")
public class User implements java.io.Serializable {
...

// used as a alias on the site (ok to have space, some punctuation)
@Column(name = "screenName", nullable = false, unique = true)
@NotNull
@Length(max = 30)
@Field(name="screenName", index= Index.UN_TOKENIZED, store = Store.YES)
private String screenName;
...
}

In persistence.xml:

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

According to the instruction on this thread, I put hibernate-search.jar (3.0.0.beta1), hibernate-commons-annotations.jar (3.0.0GA) and lucene-core-2.1.0.jar into ear file, and put their references in application.xml. The rest of hibernate jars are under jboss/server/default/lib. The hibernate core jar version is 3.2.2. I then manually created c:\temp\luceneIndex\user which was where the index was supposed to be. After I created a User from the app, nothing happens in the directory. There was no log indicating errors or indexing ever happened.

What did I do wrong?

Thanks.

did you forget the @DocumentId on your entity's primary key?

I did have @DocumentId, in the following form:


@Id @GeneratedValue
@Column(name = "id", unique = true, nullable = false)
@NotNull
@DocumentId
private Long id;

Not working is pretty vague, but did you follow those 2 steps?

I was happy too early. After I switched to the latest hibernate jars, the index directory was created when I started the app (which was a step forward and I thought everything was fine and dandy). But no entity was indexed. For example, there would be a "user" directory under indexBase, but when I add user the new user would not get indexed.

I use EntityHome's persist() method which fires off PersistEvent, does Hibernate search listens to this event or how do I hook up this event to Hibernate search?

Thanks again.

Did you solve your problem? Because I'd like to know too. Thanks.

If the directory are created but nothing is indexed, it might be because you don't commit the transaction after persisting.
