I had created some tool which was populating the google spreadsheet. It was working fine for 1 year, since today I've error
Exception in thread "main" com.google.gdata.util.AuthenticationException: Error authenticating (check service name)
at com.google.gdata.client.GoogleAuthTokenFactory.getAuthException(GoogleAuthTokenFactory.java:688)

at com.google.gdata.client.GoogleService.setUserCredentials(GoogleService.java:303)
This is the part of code to connect with gmail:
String USERNAME = "[email protected]"; ->of course I'm using proper username and password
String PASSWORD = "*******";
SpreadsheetService service
= new SpreadsheetService("SandboxCheck");
service.setUserCredentials(USERNAME, PASSWORD);
I don't know how to connect with gmail, I was trying to do this via oAuth but I don't know how to do this. In examples on https://developers.google.com/google-apps/spreadsheets/authorize there is only code for .net.
I finally with help from here managed to create such connection. Everything is working as before. Steps You have to do is:
Below is the working code
import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.jackson.JacksonFactory;
import com.google.gdata.client.spreadsheet.SpreadsheetService;
import com.google.gdata.data.spreadsheet.SpreadsheetEntry;
import com.google.gdata.data.spreadsheet.SpreadsheetFeed;
import com.google.gdata.util.ServiceException;
import java.io.File;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.security.GeneralSecurityException;
import java.util.Arrays;
import java.util.List;
public class OAuthIntegration{
public static void main(String[] args) throws MalformedURLException, GeneralSecurityException, IOException, ServiceException {
URL SPREADSHEET_FEED_URL;
SPREADSHEET_FEED_URL = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");
File p12 = new File("./key.p12");
HttpTransport httpTransport = new NetHttpTransport();
JacksonFactory jsonFactory = new JacksonFactory();
String[] SCOPESArray = {"https://spreadsheets.google.com/feeds", "https://spreadsheets.google.com/feeds/spreadsheets/private/full", "https://docs.google.com/feeds"};
final List SCOPES = Arrays.asList(SCOPESArray);
GoogleCredential credential = new GoogleCredential.Builder()
.setTransport(httpTransport)
.setJsonFactory(jsonFactory)
.setServiceAccountId("cliend_ID")
.setServiceAccountScopes(SCOPES)
.setServiceAccountPrivateKeyFromP12File(p12)
.build();
SpreadsheetService service = new SpreadsheetService("Test");
service.setOAuth2Credentials(credential);
SpreadsheetFeed feed = service.getFeed(SPREADSHEET_FEED_URL, SpreadsheetFeed.class);
List<SpreadsheetEntry> spreadsheets = feed.getEntries();
if (spreadsheets.size() == 0) {
System.out.println("No spreadsheets found.");
}
SpreadsheetEntry spreadsheet = null;
for (int i = 0; i < spreadsheets.size(); i++) {
if (spreadsheets.get(i).getTitle().getPlainText().startsWith("ListOfSandboxes")) {
spreadsheet = spreadsheets.get(i);
System.out.println("Name of editing spreadsheet: " + spreadsheets.get(i).getTitle().getPlainText());
System.out.println("ID of SpreadSheet: " + i);
}
}
}
}
