Hibernate Search with XML files mapping entities?

Hi all,
I would like to know if I can use Hibernate Search programmatic API with an XML file mapping all my entities?

I tried to use a SearchMapping on MyCLassDefinition like this:
Here is the mapping:

Code:

<class name="MyClassDefinition" table="CLASS_DEF_">
    <id name="dbid" column="DBID_">
      <generator class="native" />
    </id>
    <property name="name" column="NAME_" />
    <property name="description" column="DESCRIPTION_" />
  ...
</class>

And the searchmapping code:

Code:

SearchMapping mapping = new SearchMapping();
mapping.entity(MyClassDefinition.class).indexed()
  .property("dbid", ElementType.FIELD).documentId().name("dbid")

But I got a SearchException : No document id in: MyClassDefinition

Regards,
Matti

Hi,

I think it should work. Could you post the whole exception?

Hi,
The main exception is: org.hibernate.HibernateException: could not init listeners (without any stacktrace)
I found the SearchException : No document id in: MyClassDefinition when I used the debugger.

I do not understand why I get the HibernateException becuase I had to my configuration the good listeners

Code:

  configuration.setListener("post-update", new FullTextIndexEventListener());
  configuration.setListener("post-insert", new FullTextIndexEventListener());
  configuration.setListener("post-delete", new FullTextIndexEventListener());
  configuration.setListener("post-collection-recreate", new FullTextIndexEventListener());
  configuration.setListener("post-collection-remove", new FullTextIndexEventListener());
  configuration.setListener("post-collection-update", new FullTextIndexEventListener());
  String[] listeners = new String[] {DefaultFlushEventListener.class.getName(), FullTextIndexEventListener.class.getName()};
  configuration.setListeners("flush", listeners);

And I set hibernate.search.autoregister_listeners to false.

Regards,
Matti

I finally found the stack trace :)

Hope it will help you

Hi,

could you please humor me and try this:

Code:

SearchMapping mapping = new SearchMapping();
mapping.entity(MyClassDefinition.class).indexed()
  .property("dbid", ElementType.FIELD).documentId().name("id")

Hi,
I still get the same exception.

Might not be related, but you don't have to create a new listener for each event type. Just create one and use it for all events.

Hi,
I found why Hibernate Search does not found the document id. The dbid field was not defined in MyClassDefinition but in its parent class. I put dbid field in myClassDefinition. And now the mapping works!

Thanks for your help

We should raise a meaningful exception, it seems. Please open a JIRA issue.
