Hi all!

I'm trying to integrate Hibernate Search, and when adding the event listeners in the config file, it throws:

[INFO] (class: org/hibernate/search/event/FullTextIndexEventListener, method: on
PostInsert signature: (Lorg/hibernate/event/PostInsertEvent;)V) Incompatible arg
ument to function
[INFO] ------------------------------------------------------------------------
[INFO] Trace
java.lang.VerifyError: (class: org/hibernate/search/event/FullTextIndexEventList
ener, method: onPostInsert signature: (Lorg/hibernate/event/PostInsertEvent;)V)
Incompatible argument to function
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Class.java:2357)
....etc

I've been reading other posts, in which recommended update versions of hibernate-core, annotations, etc.

I'm using hibernate 3.2.3.ga; annotations 3.3.0.ga; search 3.0.0.Beta1.

Any idea?

Double check your classpath, usually it means you forgot an old hibernate-annptations.jar or hibernate3.jar in your classpath

Uhmm I've checked the classpath and I don't have old references :s
I've also checked the signatures of the methods that seem broken, and are OK too...

The problem is that I use the same claimed combination as you do and it works fine, inside and outside the app server, So I don't know what to tell you :-(

The thing is I do have hibernate-annotations because for eg. AccessType needs it. Besides, it's only when I try to register the event listeners. If I take out those lines from the hibernate conf, everything's alright.

I send u here the class I am persisting and pretending to index...

@Entity
@AccessType("field")
@Table(name = "userfile")
@Indexed(index="indexes/userfile")
public abstract class UserFile {

/* ATTRIBUTES */

/**
* Unique ID for each file in the system.
*/
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@DocumentId
private long id;

/**
* Logical name for the file, it must be unique within the group
* of files of the same type for a given user.
*/
@Column (length = 100)
@Field(index=Index.TOKENIZED, store=Store.YES)
private String name;

/**
* Short file description.
*/
@Column (length = 200)
@Field(index=Index.TOKENIZED, store=Store.YES)
private String description;

etc.....

and the hibernate configuration:

...
<property name="hibernate.search.default.directory_provider">
org.hibernate.search.store.FSDirectoryProvider
</property>

<property name="hibernate.search.default.indexBase">
C:\lucene\indexes
</property>

....mappings....

<event type="post-update">
<listener
class="org.hibernate.search.event.FullTextIndexEventListener" />
</event>
<event type="post-insert">
<listener
class="org.hibernate.search.event.FullTextIndexEventListener" />
</event>
<event type="post-delete">
<listener
class="org.hibernate.search.event.FullTextIndexEventListener" />
</event>
</session-factory>

</hibernate-configuration>

Are you using Hibernate Annotations (ie AnnotationConfiguration) to build your session factory?
If so, you should not even have to register the events, check the Hibernate Annotations version number in the logs (INFO level), you can also check the Hibernate Core version number too to be safe

I removed the event listeners mapping, and checked my versions:

INFO [ Version.java:15 ] - Hibernate Annotations 3.2.1.GA
INFO [ Environment.java:509 ] - Hibernate 3.2.3

I've developed my controller and services using Spring, and when testing the following is logged:

org.hibernate.HibernateException: Lucene event listener not initialized
at org.hibernate.search.util.ContextHelper.getLuceneEventListener(ContextHelper.java:24)
at org.hibernate.search.query.FullTextQueryImpl.list(FullTextQueryImpl.java:137)

Any idea?

if you use the latest Search version, you have to use Hibernate Annotations 3.3.x (check the compatibility matric in the download page of www.hibernate.org
