Hi Austin (or any other Google Consultants ^^),
Recently we'd like to use calendar to do some apps. However, following
your steps, we found some more questions:
//
==========================================================================================
URL u = new URL("http://www.google.com/calendar/feeds/default/
private/full/vinopclakkco4q55ivuip28220");
URL um = new URL("http://www.google.com/calendar/feeds/default/
private/full/vinopclakkco4q55ivuip28220/comments");
CalendarEventEntry ee = myService.getEntry(u,
CalendarEventEntry.class); // successfully get the event entry
MessageFeed messageFeed = myService.getFeed(um,
MessageFeed.class);
Iterator messageIter = messageFeed.getEntries().iterator();
while (messageIter.hasNext())
{
MessageEntry message = (MessageEntry) messageIter.next();
String content = ((TextContent)
message.getContent()).getContent().getPlainText();
System.out.println(content);
//======== the results for above "getContent" and the below
"getAuthors" are all OK, thx. ===================
Iterator personIter = message.getAuthors().iterator();
while(personIter.hasNext()) {
Person o = (Person) personIter.next();
String str = o.getEmail()+","+o.getUri()+","+o.getName();
System.out.println(str);
}
}
//====== want to add a new comment,
but ...===================================================
//
HtmlTextConstruct htc = new HtmlTextConstruct("Successful add!");
MessageEntry message = new MessageEntry();
message.setContent(htc);
//------------------------------
> content for new comment message
Person o = new Person("", null, "[EMAIL PROTECTED]");
message.setExtension(o);
//------------------------------
> author for new comment message
URL uc = new
URL(ee.getExtension(Comments.class).getFeedLink().getHref()); // same
as URL um as above
// we want to add a new message prepared like above and execute
the following insert, ...
myService.insert(uc, message);
// but two kinds of error messages appear:
// first, if we do not state: "message.setExtension(o);" the
error messages are
That's all right! => the exist message content
[EMAIL PROTECTED],null,I-Horng Jeng => the exist message author

Could you do me a favor to answer this? Thanks a lot!
