Hi,
Some code would be helpful, have you checked the form for errors? you
can use httpfox to see whats going to the servlet.
You can use this line of code to get the blob info, "LOLUPLOAD" being
the name of the FileUpload widget.
private BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
...
BlobInfo info = new
BlobInfoFactory().loadBlobInfo(blobstoreService.getUploadedBlobs(req).get("LOLUPLOAD"));
