Hi,
I updated to all the compliant versions and jars and am trying a simple lucene query over my models, which I store/retrieve already.

Here is the code:

Code:
            FullTextSession fullTextSession = Search.createFullTextSession(
                    session);
            org.apache.lucene.queryParser.QueryParser parser = new QueryParser(
                    defaultField, new StopAnalyzer());

            org.apache.lucene.search.Query luceneQuery = parser.parse(query);
            org.hibernate.Query fullTextQuery = fullTextSession.createFullTextQuery(
                    luceneQuery);

            List result = fullTextQuery.list(); //return a list of managed objects

            return result;


Other useful snips:
Code:
      <property name="current_session_context_class">thread</property>
      <property name="hibernate.search.default.indexDir">C:\hibernate\indexes</property>
      <property name="hibernate.search.default.directory_provider">org.hibernate.search.store.FSDirectoryProvider</property>


I am running hibernate in local thread, not container.

Thanks for any tips.

Darren

Sounds to me like you are using a transaction bound session outside a transaction, that's bad :-)

if you want to do that, I would recommend the ManagedSessionContext

I am new to this, so thanks for the tips. I read the session/transaction docs and demarcated my code like this to get past that exception:

Code:
           session.beginTransaction();
            FullTextSession fullTextSession = Search.createFullTextSession(
                    session);
            org.apache.lucene.queryParser.QueryParser parser = new QueryParser(
                    defaultField, new StopAnalyzer());

            org.apache.lucene.search.Query luceneQuery = parser.parse(query);
            org.hibernate.Query fullTextQuery = fullTextSession.createFullTextQuery(
                    luceneQuery);

           
            List result = fullTextQuery.list(); //return a list of managed objects
            session.getTransaction().commit();



But I reached another exception I do not understand yet.

Hi.

Thanks for the link. I know less about JMS than I do about lucene, but will read this thoroughly.

I set this property

<property name="hibernate.search.autoregister_listeners">false</property>

in the hibernate config file to disable it and the exception still occurs.

But then I realized, I use explicit hibernate annotations to index certain fields and thus do not need this automatic indexing.

How can I get around the exception in this case?


thanks,
Darren

If you want to use Hibernate Search, you must have the event registered, the easy way is to let the default (no property, no explicit event listener) do the job.
