Re: [hibernate-dev] Hibernate Search fails to generate anything
Hi Koen,
this is a classloader issue for which we'll need your help. It's a
very simple issue: Hibernate ORM needs to see the services exposed
from Hibernate Search when the SessionFactory is started, so that it
triggers the correct integrations.
My guess is that some metadata needs to be changed in the Hibernate
ORM plugin to allow loading from the Search module. Is that something
you could help Dmitry with?
thanks,
Sanne

Hello, everyone!
I'd like to discuss with you the problem. I'm writing a hibernate-search
eclipse plugin and currently I have a problem with generating indexes.
I try to generate indexes in HSearchServiceProxy class
<https://github.com/Sanne/org.jboss.tools.hibernate.search/blob/master/hse...;.
The code runs till the end fine. I was able to debug it. However, nothing
is created.
I have a user project. In hibernate.cfg.xml there is:
* <property
name="hibernate.search.default.directory_provider">filesystem</property>*
* <property
name="hibernate.search.default.indexBase">D:\Spring\HibernateWS\gen_indexes</property>*
Also there is
* <dependency>*
* <groupId>org.hibernate</groupId>*
* <artifactId>hibernate-search-orm</artifactId>*
* <version>5.0.1.Final</version>*
* </dependency>*
in the *pom.xml* in order to annotate entities to index them:
*@Entity*
*@Indexed*
*public class Person implements java.io.Serializable {*
* @Id*
* @GeneratedValue*
* private int id;*
* @Field(analyze=Analyze.YES, store=Store.NO)*
* private String login;*
When i try to create indexes as a user - it works fine. However, when I try
to do it from my plugin nothing happens. I debugged and found that the call
stack is the following: MassIndexerImpl.startAndWait() ->
FullTextSessionImpl.getSearchIntegrator() ->
ContextHelper.getSearchintegratorBySFI(SessionFactoryImplementor sfi) ->
SearchFactoryReference.getSearchIntegrator(). And here
<https://github.com/hibernate/hibernate-search/blob/c06e4fe5fbc6b5a09195f4...
it
creates and exception in getSearchIntegrator() because
this.extendedIntegrator returns null.
As I understand plugin classloader is different from user classloader. So
that can be a problem. In my plugin I have hibernate-core 4.3.1 (from
jbosstolls-hibernate) and hibernate-search (5.0.1 as a fragment of this
jbosstolls-hibernate plugin) in the classpath. I found that versions are
compatible, so it's not a problem.
So the only problem, as I think, are different classloaders.
Koen Aers and Sanne Grinovero are in touch with the problem. So If anyone
else has any thoughts, it would be great to see =)
Thanks in advance!
Dmitry
