    Marshall / Unmarshall problem or EOF

    Kid Java Newbie

      I have a java client with the following main method:

      public static void main(String[] args) {

      try {

      Context context = new InitialContext();
      t = ( Test ) context.lookup(Test.class.getName() );
      t2 = ( Test2 ) context.lookup( Test2.class.getName() );
      rm = ( RecordManager ) context.lookup( RecordManager.class.getName() );
      } catch ( NamingException e ) {

      e.printStackTrace();
      }

      System.out.println( t.callMe() );
      System.out.println( "3 + 5 = " + t.addCalc( 3, 5 ) );
      System.out.println( t2.callMe() );
      System.out.println( "3 * 5 = " + t2.calcMult( 3, 5 ) );
      System.out.println( rm.getSomeRecords() );
      System.out.println( "Calling get100Records . . . " );

      for ( SkidEntity skid : rm.get100Records() )
      {
      System.out.println( skid.getSkidId() );
      }
      }

      I have an EntityBean and Stateless Session Bean. The get100Records method is:

      public List< SkidEntity > get100Records() {

      ArrayList arrayList = new ArrayList();
      Query q = em.createQuery( "from SkidEntity" );
      for( Object o : q.getResultList() ) { arrayList.add( ( SkidEntity ) o ); };
      return arrayList;
      }

      If the body of the for loop is empty is works. If it is as is I get:

      You called TestBean.callMe().
      3 + 5 = 8
      You called Test2Bean.callMe.
      3 * 5 = 15
      RecordManagerBean.getSomeRecords - Under Construction
      Calling get100Records . . .
