Hi there, I am using app engine and (Java) Google Base API to do a UPC query lookup, using the following code:
GoogleBaseService service = new GoogleBaseService("Service"); GoogleBaseQuery query = new GoogleBaseQuery(FeedURLFactory.getDefault().getSnippetsFeedURL()); query.setGoogleBaseQuery(upcCode); query.setMaxResults(3); GoogleBaseFeed feed = service.query(query); When running locally, it works great. I get entries that contain data about the product. However, when I upload my app to app engine and try running the same code from myapp.appspot.com , I get an error with the following stack trace: com.google.gdata.client.http.HttpGDataRequest:558 isOAuthProxyErrorResponse() com.google.gdata.client.http.HttpGDataRequest:549 checkResponse() com.google.gdata.client.http.HttpGDataRequest:530 execute() com.google.gdata.client.http.GoogleGDataRequest:535 execute() com.google.gdata.client.Service:1135 getFeed() com.google.gdata.client.Service:1077 getFeed() com.google.gdata.client.GoogleService:662 getFeed() com.google.gdata.client.Service:1237 query() com.google.gdata.client.Service:1178 query() com.google.api.gbase.client.GoogleBaseService:397 query() It seems it is expecting me to do some sort of user authentication. However, I believe that the query doesn't require authentication. Does using the Java Google Base API on App Engine require some extra steps that I am missing? Can anyone help me?
