Session Bean could not be instantiated

[ben27]

Hi,

I have a problem with a session bean. Maybe anybody can help me. I did it in a similar way with Seam 2.0.2 SP1 and JBoss 4.2.2 GA App Server.

Here is the code of the bean:

@Name("entitiesList")
public class EntitiesList extends EntityQuery<Entities>
{

        @Logger
        Log log;

        @DataModelSelection
        private Entities selectedStructure;

        @DataModel
        private List<Entities> structures;
        
        @In(create=true)
        private int[] results;

        public List<Entities> getStructures() {
                return structures;
        }

        public void setStructures(List<Entities> structures) {
                this.structures = structures;
        }

        public Entities getSelectedStructure() {
                return selectedStructure;
        }

        public void setSelectedStructure(Entities selectedStructure) {
                this.selectedStructure = selectedStructure;
        }

    private static final String[] RESTRICTIONS = {... };

    private Entities entities = new Entities();

    public EntitiesList()
    {
        if(results == null) {
                        System.out.println("RESULTS = NULL");
                        setEjbql("");
                } else {
                        setEjbql("select entities from Entities entities where cd_id IN " + EjbQueryUtil.convertIdArrayToInString(results));
                }
        setRestrictionExpressionStrings(Arrays.asList(RESTRICTIONS));
        setMaxResults(25);
    }

        @Destroy @Remove
        public void destroy(){}

    public Entities getEntities()
    {
        return entities;
    }

    public void searchNotify(ActionEvent event){
                log.info("Inside Search Notify");
                Events.instance().raiseEvent("resetResults");
        }
}

The searchNotify method is called from a xhtml page. It notifies another method where the results array is filled. I got the following exception:

Can anybody help me?
