    FullTextHibernateSessionProxy is not visible from class loader

    Jakob D Newbie

      Hello experts!


      I have run into a very strange error that I can´t wrap my head around. I´m running Seam 2.2.1.CR2 and JBoss 4.3.0.GA.
      My application consist of 3 modules:


      application.xml



      <display-name>CoolWebApp</display-name>
          <module id="EJB3">
              <ejb>EJB3.jar</ejb>
          </module>
          <module id="WEB">
              <web>
                  <web-uri>WEB.war</web-uri>
                  <context-root>/</context-root>
              </web>
          </module>
          <module>
              <ejb>jboss-seam-2.2.1.CR2.jar</ejb>
          </module>



      The following bean is scheduled and should run asynchronously. It resides in my EJB3 module: 



      package com.coolwebapp.indexing;

          private EntityManager entityManager() {

          }

              final EntityManager em = entityManager();
              List<CompanyInNeedOfIndexing> indexingTasks =
                       em.createQuery(

                              .setParameter("nodeName", getNodeName())
                              .getResultList();
      
              Map<Long, Company> idToCompanyToIndexMap = new HashMap<Long, Company>();
              for (CompanyInNeedOfIndexing indexingTask : indexingTasks) {
                  final Company company = indexingTask.getCompany();
                  final long id = company.getId();
                  if (!idToCompanyToIndexMap.containsKey(id))
                      idToCompanyToIndexMap.put(id, company);
              }

                  Events.instance().raiseEvent(CompanyTouched.EVENT_NAME, company, em);
                  em.persist(new CompanyInNeedOfIndexing(company, getNodeName()));
              }
          }
      
          private String getNodeName() {
              return "N0";    // TODO get from -D param
          }
      
          @Startup(depends = {"applicationBean", "entityManager"})
          @Scope(ScopeType.APPLICATION)
          @Name("indexBeanKicker")
          public static class Kicker {
      
              private final long INTERVAL = 15;
      
      
              @In
              private IndexBean indexBean;
      
              @Create
              public void initBean() {
                  log.info("Will check for indexing every " + INTERVAL + " minutes.");
                  final Date firstRunIn30sec = new Date(30 * DateUtils.MILLIS_PER_SECOND + System.currentTimeMillis());
                  indexBean.investigatePendingIndexings(
                          firstRunIn30sec, 
                          INTERVAL * DateUtils.MILLIS_PER_MINUTE);
              }
          }
      
      }



      When the event is raised following bean picks it up(also in EJB3 module):




      package com.coolwebpp.search.util;
      
      import org.apache.commons.logging.Log;
      import org.apache.commons.logging.LogFactory;
      import org.apache.lucene.document.Document;

      import com.coolwebapp.model.Company;
      
      import javax.persistence.EntityManager;
      import java.io.Serializable;
      
      @Name("indexUtils")
      @AutoCreate
      @Scope(ScopeType.SESSION)
      public class IndexUtils implements ArticleSaved, ReviewsUpdated, CompanyPublished, CompanyRemoved, SearchWordsUpdated, CompanyTouched, Serializable {
      
          public final static Log log = LogFactory.getLog(IndexUtils.class);
      
          public IndexUtils() {
          }
      
          public static FullTextEntityManager getFullTextEntityManager(EntityManager entityManager) {
              if (entityManager instanceof FullTextEntityManager)
                  return (FullTextEntityManager) entityManager;
              else
                  return Search.createFullTextEntityManager(entityManager);
          }
      
          private void reindexWithoutModifyingLastUpdated(Company company, EntityManager entityManager) {
              log.warn("--------------->>> Reindexing without updating lastModified: " + company.getName());
              getFullTextEntityManager(entityManager).index(company);
          }
      
          @Observer(CompanyTouched.EVENT_NAME)
          public void handleCompanyTouched(Company owningCompany, EntityManager entityManager) {
              reindexWithoutModifyingLastUpdated(owningCompany, entityManager);
          }
      
      }
      



      components.xml




      <persistence:managed-persistence-context name="entityManager"
                                                 auto-create="true"
                                                 entity-manager-factory="#{entityManagerFactory}"/>
      
        <persistence:entity-manager-factory name="entityManagerFactory"
                                            persistence-unit-name="theDatabase"/>
      






      When I start the application and the kicker kicks in everything works well until


      getFullTextEntityManager(entityManager).index(company);



      Then following exception is thrown:

      The fulltextentitymanager comes from hibernatesearch-3.0.1.GA.


      If I remove the line calling .index saving the entity works( em.persist(new CompanyInNeedOfIndexing(company, getNodeName())); ), but only if I have the scope set to APPLICATION.


      Do you have any ideas why this doesn't work? Do you any tips or do you need more information.
      Thank you in advance,
      Jakob
