Hi there,

To update my indexes, I use this code, explained at page 154 of the hibernate search in action book.
Code:
    @RequestMapping("updateindex")
    public ModelAndView luceneIndex(HttpServletRequest req) {
   logger.debug("Re-Building Lucene index");
   Session session = sessionFactory.openSession();
   session.beginTransaction();
   FullTextSession fts = org.hibernate.search.Search.getFullTextSession(session);
   fts.setFlushMode(FlushMode.MANUAL);
   fts.setCacheMode(CacheMode.IGNORE);
   if (logger.isDebugEnabled()) {
       logger.debug("Beginning transaction ...");
   }
   Transaction tx = fts.beginTransaction();
   // Read the data from the database - Page 154 Hibernate search
   List<Class> reindexClasses = new ArrayList<Class>();
   reindexClasses.add(EnterpriseLang.class);
   reindexClasses.add(Categories.class);
   reindexClasses.add(Province.class);
   reindexClasses.add(Commune.class);
   reindexClasses.add(BusinessUnit.class);
   try {
       int index = 0;
       for (Class c : reindexClasses) {
      if (logger.isDebugEnabled()) {
          logger.debug("Starting reindex of " + c);
      }
      ScrollableResults results = fts.createCriteria(c).scroll(ScrollMode.FORWARD_ONLY);
      while (results.next()) {
          index++;
          if (logger.isDebugEnabled()) {
         logger.debug("Got Object for re-indexing: " + results.get(0).toString());
          }
          fts.index(results.get(0));
          if (index % 100 == 0) {
         fts.flushToIndexes();
         fts.clear();
          }
      }

       }
       tx.commit();
   } catch (Exception e) {
       tx.rollback();
       logger.warn("Unable to update indexes", e);
   }
   return null;
    }



On my development computer, that runs well both on MySQL and DB2.
On the test server it makes this error :
Code:

As on my test computer it runs fine, I guess there is some mis-configuration anywhere, but where? I've no idea ... maybe you have some ...

org.hibernate.AssertionFailure: scrollable result sets are not enabled

Scrollable results need to be enabled in the Hibernate configuration, they are likely not enabled (disabled is the default as some drivers don't behave correctly). Also some drivers don't implement them.

Thanks, and how do I enable that ?
Hibernate.org is doing a 404 error ...

I still think it's strange that the same war on two different machines haven't the same comportment ...
