Hi all,

I'm new in Calendar and GData. I'm getting the following error when I
try to create the CalendarService and I don't know the cause:


com.google.gwt.user.client.rpc.InvocationException: The call failed on
the server; see server log for details

I'm using GWT in java, and I'm executing my application in hosted
mode, and I don't know where to look for the server (see server log
for details...)

My code is the following one:

class CreateReservationServiceImpl.java:
[...]
CalendarAdministration cal = new CalendarAdministration();
cal.GetAgenda();
[...]

class CalendarAdministration.java:
public class CalendarAdministration
{
        static CalendarService myService = null;

        public CalendarAdministration ()
        {}

        public static void GetAgenda() {
                myService = new CalendarService("example1.0");

                try {
                        myService.setUserCredentials("[email protected]", 
"argia2009");
                } catch (AuthenticationException e) {
                e.printStackTrace();
        }
        URL feedUrl = null;
        try {
                feedUrl = new URL("http://www.google.com/calendar/feeds/
default/allcalendars/full");
        } catch (MalformedURLException e) {
                e.printStackTrace();
        }
        CalendarFeed resultFeed = null;
        try {
                resultFeed = myService.getFeed(feedUrl,
CalendarFeed.class);
        } catch (IOException e) {
                e.printStackTrace();
        } catch (ServiceException e) {
                e.printStackTrace();
        }

        System.out.println("Your calendars:");
        System.out.println();

        for (int i = 0; i < resultFeed.getEntries().size(); i++) {
          CalendarEntry entry = resultFeed.getEntries().get(i);
          System.out.println("\t" + entry.getTitle().getPlainText());
        }
}


Can you help me please?

Thank you in advance!  :)
