Hi,
I've been playing around with google app engine and I'm running into
some problems with trying to to request a contact data feed. Here is
a snippet of my code:
String urlFromAuthSub = req.getQueryString();
String token = AuthSubUtil.getTokenFromReply(urlFromAuthSub);
String sessionToken = null;
sessionToken = AuthSubUtil.exchangeForSessionToken(token, null);
ContactsService myService = new
ContactsService("contacts-app-v1");
myService.setAuthSubToken(sessionToken, null);
URL feedUrl = new
URL("http://www.google.com/m7/a/alliancefilms.com/
default/full");
Query myQuery = new Query(feedUrl);
// Next line fails
ContactFeed resultFeed = myService.query(myQuery,
ContactFeed.class);
When I run, I get this error:
HTTP ERROR: 500
Could not initialize class

RequestURI=/view
