[appengine-java] Re: How to use picasa upload api on Google App Engine
why are you not using another class that implements the MediaSource interface - e.g., MediaByteSource or MediaStreamSource? regards, andr On 11 Nov., 21:22, Ikai L (Google) ika...@google.com wrote: Kishore, Here are the docs related to sending the data as binary:http://code.google.com/apis/picasaweb/docs/2.0/developers_guide_proto...

Kishore, Here are the docs related to sending the data as binary: http://code.google.com/apis/picasaweb/docs/2.0/developers_guide_protocol.html#PostPhotos This is the raw protocol. Here are the steps you'll have to take: 1. Accept a file upload and buffer it in memory ( http://code.google.com/appengine/kb/java.html#fileforms) 2. Format the authorization headers and POST body as necessary 3. Open an HTTP connection using URLFetch: http://code.google.com/appengine/docs/java/urlfetch/overview.html (Note the limits) You'll need to do some research into the exact format for uploads to the Picasa API.
