[feedback: It would help clear up some confusion if there were a comment in the code samples explaining how to determine the post URL for insert operations. Or at least references back to the overview of Atom and feeds.]

I read through this thread

http://groups.google.com/group/Google-Picasa-Data-API/browse_thread/thread/2cfe380585291db6

and found Kyle's advice for determining an album's feed URL (Hi Kyle, small world!). I give the following URL to a browser:

http://picasaweb.google.com/data/feed/api/user/john.methot?kind=album

and get back and XML file containing the following link for my album (after running the code below, which creates the album in question):

<link rel="http://schemas.google.com/g/2005#feed" type="application/ atom+xml" href="http://picasaweb.google.com/data/feed/api/user/ john.methot/albumid/5050099601765509809" />

If I do this programmatically by getting the AlbumEntry's ID, it seems to be the same as the feed link's href. But when I try to post to that URL (last code line below), I get the output below (InvalidEntryException: Bad Request Invalid Request URI).

Note that I'm creating an album, then trying to immediately get the new album's feed URL and insert a photo. Album creation is working fine.

Thanks for any help.

PhotoEntry myPhoto = new PhotoEntry(); myPhoto.setTitle(new PlainTextConstruct("Sunset.jpg")); myPhoto.setDescription(new PlainTextConstruct("Darcy on the beach")); myPhoto.setClient("myClientName"); GregorianCalendar cal = new GregorianCalendar(2004, 4, 21); myPhoto.setTimestamp(cal.getTime());

MediaFileSource myMedia = new MediaFileSource(new File("/temp/ Sunset.jpg"), "image/jpeg"); myPhoto.setMediaSource(myMedia);

PhotoEntry returnedPhoto = (PhotoEntry)myService.insert(albumURL, myPhoto);
