Question

I have stored the file as blob in app engine using java. the blobInfo displays all the details.i have already displayed using the following code:

 BlobInfoFactory blobInfoFactory = new BlobInfoFactory();
 Iterator<BlobInfo> blobInfos = blobInfoFactory.queryBlobInfos(); 

Now how to retrieve the file name attribute alone in java?

Answer 1

You need the blobKey, then the simplest would be :

BlobInfo blobInfo = blobInfoFactory.loadBlobInfo(blobKey)
String blobFilename = blobInfo.getFilename();
