Hi,
I´m using hibernate search in a simple project(standalone) and it works fine.
Now i´m trying to use it on a web project(richfaces + tomcat). I´m using the same class of the standalone project but does not work.

The "indexBase" property is configured like this
Code:
   <property name="hibernate.search.default.indexBase">
        ../webapps/JBancoTalentos/WEB-INF/indices
    </property>


in the standalone project, "indexBase" was configured like this
Code:
   <property name="hibernate.search.default.indexBase">
        c:\_indexes
    </property>


// execute the search
Code:
   @SuppressWarnings("unchecked")
   private List<Curriculo> pesquisar(String[] campos, String strQuery) {      

      luceneSession = Search.createFullTextSession(session);
      MultiFieldQueryParser parser = new MultiFieldQueryParser(campos, new StandardAnalyzer());

      try {
         luceneQuery = parser.parse(strQuery);
      } catch (ParseException e) {
         e.printStackTrace();
      }
      fullTextQuery = luceneSession.createFullTextQuery(luceneQuery, Curriculo.class);
      System.out.println(fullTextQuery.toString());
      List<Curriculo> lista = new ArrayList<Curriculo>();
      try {
         lista = fullTextQuery.list(); // * E R R O R *
      } catch (Exception ex) {
         ex.getMessage();
         ex.printStackTrace();
      }
      return lista;
   }


the full stack trace

I´m using apache-tomcat 6.0.18, hibernate-distribution-3.3.1.GA, hibernate-annotations-3.4.0.GA and hibernate-search-3.0.1.GA
PS: sorry for my "bad" english

Thanks!

Looks like a Session problem at the first glance. Are you sure you your Session object is not null. How do you use Hibernate within the webapp? Do you the Open Session in View pattern (https://www.hibernate.org/43.html)?

As a sidenode, I would not use a relative path in the index base. It is relative to the directory the JVM gets started in. In case you make some changes to the startup script Hibernate Search might not be able to find the indexes anymore. I also wouldn't place the indexes inside the exploded webapp. Instead I would use a dedicated index directory somewhere else on the file system.

Hi Hardy.
The problem was solved. My session object was null.
Thanks for your reply.
