Collection in order

Question

hi all,
i have a one-to-many cmr from Anket entity bean to Bolum entity bean.
public class BolumType implements java.io.Serializable{
     public Integer anketID, bolumID;
     public BolumType(Integer anketID, Integer bolumID){
          this.anketID = anketID;
          this.bolumID = bolumID;
public abstract class Bolum implements EntityBean{
        public abstract BolumType getBolumID(); // primary key
        public abstract void setBolumID(BolumType id);
        public abstract String getBolumName();
        public abstract void setBolumName(String name);
public abstract class Anket implements EntityBean{
     public abstract Collection getBolums();
     public abstract void setBolums(Collection bolums);
     public ArrayList getBolumList(){
          ArrayList list = new ArrayList();
          Iterator b = getBolums().iterator();
          while(b.hasNext())
               list.add((LocalBolum)b.next());
          return list;
}calling the getBolumList() method from the local interface of the Anket bean brings the collection of bolums in disorder.. i want to retrieve the collection of bolums in order of bolumID defined in BolumType class.. i suppose i have to use an ejbSelect method..
public abstract class Anket implements EntityBean{
     public abstract Collection ejbSelectBolumsInOrder();
     public ArrayList getBolumList() throws FinderException{
          ArrayList list = new ArrayList();
          Iterator b = ejbSelectBolumsInOrder().iterator();
          while(b.hasNext())
               list.add((LocalBolum)b.next());
          return list;
}(i'm not sure whether above implementation is correct)
but if so, how can i reach bolumID defined in BolumType class with EJB-QL? or what should i do?
thanks in advance..

In your ejb-jar.xml you should have the SQL code for the queries that are being executed against the DB for each EJB. There you can modify the SQL code to execute with the Order by option, which would return an ordered resultset.
