                    // process it. Intercept it so we begin transaction.
                    getCmsXMLIngestFileUnencodedStrategy().insert(assets, folder, messageFile);

                }
            } catch (final Exception e) {

            }
            return new Pair<String, Boolean>(folder.toString(), true);


      }

I already tried to add the @Transactional annotation to the service, to the dao almost everywhere.
