    Seam 2.2.0.GA: executing task at startup time

    Fausto Morenzoni Newbie

      Hello Everyone,


      this is my issue: I have to index some data in a SQL Server 2000 database, and I have to do this task once, at startup time, just after the application is deployed.


      With this configuration I had no problem, all worked fine:




      • JBoss AS 4.2.2.GA

      • Seam 2.0.2.SP1

      • hibernate-search-3.0.1.GA-1.jar

      • hibernate-commons-annotations-3.1.0.GA.jar




      After the migration from Seam 2.0.2.SP1 to Seam 2.2.0.GA (the jars files are the same) at the deployment time I get this error:

      This is my code:

      import org.hibernate.search.FullTextSession;
      
      @Scope(ScopeType.APPLICATION)
      @Startup
      @Stateful
      @Name("indexer")
      public class IndexerBean implements Indexer {

         @Create
         public void index() {
           indexObject(Dossier.class);
           indexObject(Esibito.class);
           lastIndexingTime = new Date();
         }

         private void indexObject(Class c) {
              FullTextSession fullTextSession = (FullTextSession) em.getDelegate();

              for (Object object: records) {
                  fullTextSession.index(object);

      jndiPattern=GestioneEdiliziaPrivata_2.0-ear/\#{ejbName}/local
      embeddedEjb=false
      



      What I've already tried:


      @Startup(depends="org.jboss.seam.core.applicationContext")
      



      using @Observer instead of @Create




      @Observer("org.jboss.seam.postInitialization")
      
      or
      
      @Observer("org.jboss.seam.core.applicationContext")
      



      ... and pushed from the black despair :-) I've upgrade my hibernate jar file to version 3.1.1.GA, and modified my code according to what explained in chapter 1.4:
      Hibernate Search


      Thank you in advance to everyone that can give me some suggestions or help!

          Gabor Jakab Newbie

          hi,


          most probably it is your persistency settings, you should test if the em is injected properly before using that...


          do you use Seam 2.2.0.GA with hibernate core 3.1.1.GA? In this seam package 3.3.1.GA of hibernate is included, did you replace this to older version? Did you also changed to JBoss 5.1?


          PS: I would use some asynchronous scheduled starting of such batch in separate thread not blocking other startup tasks...

            Hi Gabor,


            thank you for your reply and yours suggestions.


            You're right, could be something about jars' versions mismatch, I haven't changed the hibernate core, I've used the version delivered with JBoss 4.2.2 (in server/default/lib directory).
            As it is plan to upgrade to JBoss 5.1 I will try to change to this AS version, and I will try to put this task in a separete thread (in this way the AS starup will surely be faster).

              Fausto Morenzoni Newbie

              The problem has been solved as follow (thanks to Gabor's suggestions):



              • Upgrade to JBoss AS 5.1 (jdk 1.6 compiled version);

              • Use of hibernate-search-3.1.1.GA jar files (all the necessary libraries are included in the zip distribution archive; lucene-core-2.4.1.jar);



              File: Indexer.java
