This should be fairly easy, yet I am getting this exception when removing a item from a
relation that is working fine.
I have the following code:
| public boolean borrarProceso(Integer id, String tipo, String userName){
|
| InitialContext ic = null;
| boolean encontro = false;
| AbogadoBeanLocalHome home;
| AdministrativoBeanLocal mover = null;;
| try {
| ic = new InitialContext();
| home = (AbogadoBeanLocalHome) ic.lookup("AbogadoBeanLocal");
| System.out.println("en cambiarAbogadoEnProceso obtengo interface home del
old");
| AbogadoBeanLocal abog = home.findByPrimaryKey(userName);
| Collection administrativos = abog.getProcesosAdministrativos();
|
| //Collection administrativosP = new ArrayList();
| //Quiro el proceso que quiero
| Iterator it = administrativos.iterator();
| System.out.println("tengo procesos: "+administrativos.size());
| while(it.hasNext()){
| AdministrativoBeanLocal proc = (AdministrativoBeanLocal) it.next();
| if(id.compareTo(proc.getId())!=0){
| System.out.println("Proceso: "+proc.getId()+" estoy buscando el:
"+id);
| //guardo todos con id diff
| //administrativosP.add(proc);
| }else{
| // HERE IS THE IMPORTANT STUFF
| encontro = true;
| //seleccion el unico con id y lo guardo
| mover = (AdministrativoBeanLocal) proc;
| administrativos.remove(mover);
| mover.remove();
| //ENDS HERE
| }
|
| }
| if(encontro){
| System.out.println("Ahora tengo uno menos: "+administrativos.size());
| //Hago set de los nuevos procesos
| abog.setProcesosAdministrativos(administrativos);
| return true;
| }else{
| System.out.println("No encontro el proceso buscado");
| return false;
| }
| }catch (NamingException e) {
| // TODO Auto-generated catch block
| e.printStackTrace();
| return false;
| } catch (FinderException e) {
| // TODO Auto-generated catch block
| e.printStackTrace();
| return false;
| } catch (EJBException e) {
| // TODO Auto-generated catch block
| e.printStackTrace();
| }
| System.out.println("Fallo borrado en centralbean");
| return false;
|
| }
|
In breaf I search for a bean, and try to remove it, but I cant seem to make it work,
