Question

使用eclipse gdata java来处理电子表格.... 现在我尝试使用以下代码将listRow上传到工作表，公共类reftome { public static void main（String [] args）抛出AuthenticationException，MalformedURLException，IOException，ServiceException {

SpreadsheetService service =
    new SpreadsheetService("MySpreadsheetIntegration-v3");
service.setUserCredentials("user@gmail.com", "pass");

// Define the URL to request.  This should never change.
URL metafeedUrl = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");
SpreadsheetFeed feed = service.getFeed(metafeedUrl, SpreadsheetFeed.class);

List<SpreadsheetEntry> spreadsheets = feed.getEntries();

if (spreadsheets.size() == 0) {
  // TODO: There were no spreadsheets, act accordingly.
}

// TODO: Choose a spreadsheet more intelligently based on your
// app's needs.
SpreadsheetEntry entry = null;
for (int i = 0; i < spreadsheets.size(); i++)
{
    entry = spreadsheets.get(i);
    String dum=entry.getTitle().getPlainText();
    if(dum.contains("reference_me"))
        break;
}
SpreadsheetEntry spreadsheet = entry;
System.out.println(spreadsheet.getTitle().getPlainText());

// Get the first worksheet of the first spreadsheet.
// TODO: Choose a worksheet more intelligently based on your
// app's needs.
WorksheetFeed worksheetFeed = service.getFeed(
    spreadsheet.getWorksheetFeedUrl(), WorksheetFeed.class);
List<WorksheetEntry> worksheets = worksheetFeed.getEntries();
WorksheetEntry worksheet = worksheets.get(0);

// Fetch the list feed of the worksheet.
URL listFeedUrl = worksheet.getListFeedUrl();
ListFeed listFeed = service.getFeed(listFeedUrl, ListFeed.class);

// Create a local representation of the new row.
ListEntry row = new ListEntry();
row.getCustomElements().setValueLocal("firstname", "Joe");
row.getCustomElements().setValueLocal("lastname", "Smith");
row.getCustomElements().setValueLocal("age", "26");
row.getCustomElements().setValueLocal("height", "176");

service.insert(listFeedUrl, row);

} }

但是最后一行“service.insert（listFeedUrl，row）;”失败并给出以下消息，

Exception in thread "main" com.google.gdata.util.InvalidEntryException: Bad Request

很抱歉，发生了服务器错误。请稍等一下，然后尝试重新加载电子表格。

任何人都可以帮我解决这个问题....？
