Hello Anuja, No, that is not possible because the actual file is not in the filesystem. But with the byte[] you can easily get a InputStream checkout: http://stackoverflow.com/questions/1802123/can-we-convert-a-byte-array-into-an-inputstream-in-java
InputStream myInputStream = new ByteArrayInputStream(file); POIFSFileSystem myFileSystem = new POIFSFileSystem(myInputStream); 2013/11/14 anuja bothra <[email protected]> > I actually wanted to parse the file in POI since I already had written > code for that in a local app. > > FileInputStream myInput = new FileInputStream(filePath); > POIFSFileSystem myFileSystem = new POIFSFileSystem(myInput); > > I need the "filePath" (the excel file's path) so that I can just pass that > and reuse the code that I had already written. > Is that not possible ? > > Thanks > > > On Thu, Nov 14, 2013 at 3:24 PM, Alejandro González Rodrigo < > [email protected]> wrote: > >> Hello Anuja, >> >> When you upload a file to the blobstore, in the /_ah/upload callback you >> can grab the BlobKey that was uploaded: >> >> BlobstoreService blobstoreService = >> BlobstoreServiceFactory.getBlobstoreService(); >> Map<String, List<BlobKey>> blobs = blobstoreService.getUploads(request); >> BlobKey *blobKey* = blobs.get("file").get(0); >> >> You need that blobkey to access the file again.
