I am trying to use the blobstore API, but I have this error:

I using this code:
@ApiMethod(name = "insertListeModel", httpMethod = "POST") public ListeModel
insertListeModel(ListeModel listemodel) { EntityManager mgr =
getEntityManager(); try { if (containsListeModel(listemodel)) { throw new
EntityExistsException("Object already exists"); } FileService fileService =
FileServiceFactory.getFileService(); if(listemodel.getImage()!=null &&
!listemodel.getImage().equals("")) { byte[] data = listemodel.getImage();
String mimeType = "image/png"; // save data to Google App Engine Blobstore
listemodel.setImage(null); mgr.persist(listemodel); AppEngineFile file; file =
fileService.createNewBlobFile(mimeType,"LM_"+listemodel.getId());
FileWriteChannel writeChannel = fileService.openWriteChannel(file, true);
writeChannel.write(java.nio.ByteBuffer.wrap(data));
writeChannel.closeFinally(); // your blobKey to your data in Google App Engine
BlobStore BlobKey blobKey = fileService.getBlobKey(file); // THANKS TO BLOBKEY
YOU CAN GET FOR EXAMPLE SERVING URL FOR IMAGES // UploadOptions uploadOptions =
UploadOptions.Builder // .withGoogleStorageBucketName("photobucket11"); // Get
the image serving URL (in https:// format) String imageUrl =
ImagesServiceFactory.getImagesService().getServingUrl(ServingUrlOptions.Builder.withBlobKey(blobKey).secureUrl(true));
// ImagesService imagesService = ImagesServiceFactory // .getImagesService();
// ServingUrlOptions servingOptions = ServingUrlOptions.Builder //
.withBlobKey(blobKey); // String imageUrl =
imagesService.getServingUrl(servingOptions);
if(listemodel.getIdBlobkey()!=null) { BlobKey blobKeytmp= new
BlobKey(listemodel.getIdBlobkey()); final AppEngineFile f =
fileService.getBlobFile(blobKeytmp); if(f.isReadable()) {
if(f.hasFinalizedName()) { fileService.delete(f); // Problematic line } } }
listemodel.setAvatar(imageUrl);
listemodel.setIdBlobkey(blobKey.getKeyString()); } mgr.persist(listemodel); }
catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace();
} finally { mgr.close(); } return listemodel; }
Can you help me?
thanks
