int start=0,flag=1;
            long size=blobInfo.getSize(),fetched=0,fetch;
            byte temp[] = null;

            while(fetched<size){
               if(size-fetched>MAX_BLOB_FETCH_SIZE)
                    fetch=MAX_BLOB_FETCH_SIZE;
               else
                    fetch=size-fetched;

               temp=blobstoreService.fetchData(blobKey,fetched,fetch );

               fetched+=fetch;
               out.println(temp);
        }

i tried to print the data of the uploaded text file using the above code but it doesn't seem to be working .
