Dear all,
Trying to work with Picasa API I have faced an issue that seems not to be
related to my code, but is caused by java library/API response stack.
Here is my code:
picasaService = new PicasawebService("exampleCo-exampleApp-1.0");
picasaService.setUserCredentials(picasaUser, picasaPassword);
baseSearchUrl = new
URL("https://picasaweb.google.com/data/feed/api/all";);
URL baseSearchUrl = new
URL("https://picasaweb.google.com/data/feed/api/all";);
Query myQuery = new com.google.gdata.client.Query(baseSearchUrl);
myQuery.setStringCustomParameter("kind", "photo");
myQuery.setMaxResults(1000);
// No additional parameters - just asking for any first 1000 photos
AlbumFeed searchResultsFeed = picasaService.query(myQuery,
AlbumFeed.class);
Here is the url that is requested:
https://picasaweb.google.com/data/feed/api/all?max-results=1000&kind=photo
And here is the Exception:
Exception in thread "main" com.google.gdata.util.ParseException: [Line 1,
Column 531149, element name] name must have a value
at
com.google.gdata.util.XmlParser.throwParseException(XmlParser.java:730)

at com.google.gdata.data.BaseFeed.parseAtom(BaseFeed.java:867)
...
Caused by: com.google.gdata.util.ParseException: name must have a value
at
com.google.gdata.data.Person$AtomHandler$NameHandler.processEndElement(
Person.java:251)

at
com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.endElement(AbstractSAXParser.java:593)

Looks like the exception fires, because the parser does not expect to see
an empty node name like this:
...<author type='owner'>*<name/>*
<uri>https://picasaweb.google.com/107435654944616411853</uri><email>1074356...
The problem has been there for about 2 years. I have found a blog article
dated June 2010
http://www.curiousattemptbunny.com/2010/07/comgooglegdatautilparseexception-name.htmlwhere
it is suggested to build own gdata-core-1.0.jar replacing just one
line of code in Person.NameHandler class, but that's too time-consuming for
everyone to do. What other ways of overcoming such issue could be
suggested? Is there a particular reason why google still has not fixed it?
Kind regards
Alexander
