我寫這我用下面的命令啓動Java應用程序連接：com.google.gdata.util.AuthenticationException：錯誤登錄URI
java -jar MyApp.jar
應用程序使用谷歌的GData Java庫編輯Google電子表格。當我從我的Mac上運行這個應用程序時，它運行良好。但是，我需要在專用服務器上運行它。當我把它上傳那裏，並嘗試運行它，我收到以下錯誤：
$ java -jar MyApp.jar

這是導致錯誤的代碼：
public static void main(String[] args) {
FeedURLFactory factory = FeedURLFactory.getDefault();
SpreadsheetService service = new SpreadsheetService("my-app");
try {
service.setUserCredentials(USER_NAME, USER_PASSWORD, ACCOUNT_TYPE);
} catch (AuthenticationException ex) {
ex.printStackTrace();
System.exit(0);
}
}我曾嘗試谷歌搜索的錯誤，並提示它通常是由代理人造成的;不過，我並不支持我的專用服務器上的代理。我寫的其他Java應用程序可以在網絡上正常工作。
任何想法如何解決這個問題？所有的幫助表示讚賞。謝謝！
