Hi
I’m using JDeveloper 11g Update 2 with an embedded WebLogic server.
If I make a simple Project in JDeveloper and add a simple Java Class
everything works fine.
package be.adf;
import com.google.gdata.client.*;
import com.google.gdata.client.calendar.*;
import com.google.gdata.data.*;
import com.google.gdata.data.acl.*;
import com.google.gdata.data.calendar.*;
import com.google.gdata.data.extensions.*;
import com.google.gdata.util.*;
import java.net.URL;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
public class Class1 {
public Class1() {
}
public static void main(String[] args) {
Class1 class1 = new Class1();
class1.createSingleOccurrenceEvent();
}
public void createSingleOccurrenceEvent() {
try {
CalendarService myService = new CalendarService("some-name");
myService.setUserCredentials("[email protected]", "password);
URL postUrl =
new URL("http://www.google.com/calendar/feeds/[email protected]/
private/full");
CalendarEventEntry myEntry = new CalendarEventEntry();
myEntry.setTitle(new PlainTextConstruct("Tennis with Beth"));
myEntry.setContent(new PlainTextConstruct("Meet for a quick
lesson."));
DateTime startTime = DateTime.parseDateTime
("2009-05-17T15:00:00-08:00");
DateTime endTime = DateTime.parseDateTime
("2009-05-17T17:00:00-08:00");
When eventTimes = new When();
eventTimes.setStartTime(startTime);
eventTimes.setEndTime(endTime);
myEntry.addTime(eventTimes);
// Send the request and receive the response:
CalendarEventEntry insertedEntry = myService.insert(postUrl, myEntry);
} catch (MalformedURLException ex) {
ex.printStackTrace();
} catch (AuthenticationException ex) {
ex.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
} catch (ServiceException ex) {
ex.printStackTrace();
} finally {
}
}
}
When I try to do the same in a Web Application (and I try to execute
the code in a managed bean) than I receive the following error on this
line:
CalendarService myService = new CalendarService("some-name");
Root cause of ServletException.

Does anyone has an idea why it’s caused?
