Erro on getRoomsPublic

[Anderson Vasconcelos]

Hi All
I try to call the method getRoomsPublic using the RoomService
(Webservice) whith the SID (value=3cacf29ca5e6e54adb2b133558d6541e)
and roomtypes_id (value=1), and i received a nullpointer on
serverside.
As you see in the stack, the method found one public room. But in line
608 of ConferenceService throws error. Today i donwload the source
code, and the line 608 is just a debug
(log.debug("getRoomClientsListByRoomId");). Anyone knows what happend?


This is the stack:

Anyone could help me?

I created a constructor in ConferenceService class and instantiated the clientListManager. This is a bug, that i founded or has something wrong in the way where i am using the openMettings webservice integration?

Thanks

Hallo Anderson,

no obviously its a Bug in our application not in your code. Since we load the object through spring this extra initialization you've made should not be needed.

Actually I think you should use this method for now:
public RoomReturn getRoomWithClientObjectsById(String SID, long rooms_id)


But I also wonder about the debug-line in your code:
public Rooms[] getRoomsPublic(String SID, Long roomtypes_id)
=> this method never invokes a method in the ConferenceService, so your initial log does somehow not fit into yoru description?

Thanks For Response Sebastian.

They was generated with a old version. But when i create a new version using the trunk source code version, i received the same error of not instantiation of ClientListManager.

In line 49 of roomService (http://openmeetings.googlecode.com/svn/trunk/singlewebapp/src/roomservice/org/openmeetings/axis/services/RoomService.java) the ConferenceService is called  as
List<Rooms> roomList = ConferenceService.getInstance().getRoomsPublic(SID, roomtypes_id);

I must register this in issue list ?

Thanks

okay but the method in the ConferenceService has no call to the clientlistmanager:

public List<Rooms> getRoomsPublic(String SID, Long roomtypes_id){
        try {
            log.debug("getRoomsPublic");
           
            Long users_id = Sessionmanagement.getInstance().checkSession(SID);
            Long User_level = Usermanagement.getInstance().getUserLevelByID(users_id);
            log.error("getRoomsPublic user_level: "+User_level);
           
           
            List<Rooms> roomList = Roommanagement.getInstance().getPublicRooms(User_level, roomtypes_id);
          
            // Filter : no appointed meetings
            List<Rooms> filtered = new ArrayList<Rooms>();
           
            for (Iterator<Rooms> iter = roomList.iterator();iter.hasNext();) {
                Rooms rooms = iter.next();
               
                if(!rooms.getAppointment()){
                    rooms.setCurrentusers(this.getRoomClientsListByRoomId(rooms.getRooms_id()));
                    filtered.add(rooms);
                }
            }
           
           
            return filtered;
        } catch (Exception err) {
            log.error("[getRoomsByOrganisationAndType]",err);
        }
        return null;
    }
