I've used Hibernate Search before very successfully. However I'm having trouble with a new project. I've narrowed the problem to attempting to index classes where I specify an entity-name in the XML map file instead of using the default full class name.

Eg classes starting with:
<class name="com.mydomain.myapp.AnswerImpl" table="answer"
entity-name="Answer">

I use XML for mappings, and annotations to specify which fields to index.

I get the following error/stackdump on application load:

org.hibernate.HibernateException: could not init listeners
at org.hibernate.event.EventListeners.initializeListeners(EventListeners.java:205)
at org.hibernate.cfg.Configuration.getInitializedEventListeners(Configuration.java:1338)
at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1327)
at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:867)

at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:187)
at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127)

[stack lines deleted for brevity]

Caused by: java.lang.NullPointerException
at org.hibernate.search.cfg.SearchConfigurationFromHibernateCore.getClassMapping(SearchConfigurationFromHibernateCore.java:31)
at org.hibernate.search.store.DirectoryProviderFactory.getDirectoryProviderName(DirectoryProviderFactory.java:226)

at org.hibernate.event.EventListeners.processListeners(EventListeners.java:181)
at org.hibernate.event.EventListeners.initializeListeners(EventListeners.java:194)
... 16 more


I did some debugging. Line 31 at
SearchConfigurationFromHibernateCore.java is:
return cfg.getClassMapping( name ).getMappedClass();

This line works for classes which have no "entity-name" attribute in the XML mapping. However when name="com.mydomain.myapp.AnswerImpl"
I get the NullPointerException mentioned above.

I am using:
hibernate-3.3.1.jar, hibernate-annotations-3.4.0.jar, hibernate-commons-annotations-3.4.0.jar, hibernate-search-3.1.0.jar, lucene-core-2.4.0.jar
on Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Linux OS.

I still haven't been able to make headway on this one, so I have created a small (ish) WAR file which should demonstrate the problem. I've also found a thread discussing a similar problem:
http://forums.hibernate.org/viewtopic.p ... d8600faa24
Unfortunately no resolution to that problem in the thread.

Please find WAR file here (source and test db dump included):
http://cms.galway.net/tmp/HibernateSearchProblem.war

Any help or pointers would be greatly appreciated.

Joe.

thank you very much, this information and test are very helpful.
Could you please open a new issue?
would it be possible to make a simple unit test to attach to the issue?

http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH

thanks a lot!

Hello,

Is the problem solved or exists a workaround? I can't find the issue for that.

thanks

I didn't test it with the latest release. I suspect it's still there. Unfortunately I never got around to registering an account with JIRA and opening a ticket.

I've run into this problem aswell. I suppose it can be worked around by using annotations for the mappings aswell. Any solutions found?

sorry, I forgot about this and nobody opened an issue to keep track of it.
I've created HSEARCH-444

A testcase is welcome and could speed things up.

I can get it to work (in some cases) but I need to understand the reasons why you are using an entity-name.
Are you keeping a 1-1 relationship between an entity-name and a class or are you using entity names to map the same class multiple times.
If the later can you explain your use case?
If the former, well can you explain your reason?

Please comment on http://opensource.atlassian.com/project ... SEARCH-444 because I don't follow this forum very closely.
