1. I have modified CaldavCollectionManager (at org/osaf/caldav4j/example) 

addEvent works fine but when trying to modify it i get an error trying to
get calendar of event (getCalendarForEventUID) with null pointer exception

The code 

public static void main(String[] args) throws CalDAV4JException,
                                               SocketException, 
                                               URISyntaxException 
{

 final String CALDAV_SERVER = CaldavCredential.CALDAV_SERVER_HOST;
 final String CALDAV_PORT =
String.valueOf(CaldavCredential.CALDAV_SERVER_PORT); 
 final String CALDAV_USER = CaldavCredential.CALDAV_SERVER_USERNAME; 
 final String CALDAV_PASS = CaldavCredential.CALDAV_SERVER_PASSWORD;

 System.out.println("Creando Cliente Caldav ..");
 BaseCaldavClient cli = new BaseCaldavClient(CALDAV_SERVER, CALDAV_PORT,
                                   CaldavCredential.CALDAV_SERVER_PROTOCOL,
                                CaldavCredential.CALDAV_SERVER_WEBDAV_ROOT,
CALDAV_USER, CALDAV_PASS);

 System.out.println("Abriendo una collection..");
 CalDavCollectionManager cdm = new CalDavCollectionManager(cli);
 cdm.setRelativePath("calPrue");

 System.out.println("Creando un evento sencillo ...");
 // create date for event
 // anyo, mes (1 menos), dia, hora (2 horas menos), minutos
 Date beginDate = ICalendarUtils.createDateTime(2009, 3, 16, 16 ,0, null,
true);
  Date endDate = ICalendarUtils.createDateTime(2009, 4, 6, null, true);
  Dur duration = new Dur("3H");
  String MyUid ="2009_00010_01_444_caldav4j";

  // create new event
  VEvent nve = new VEvent(beginDate, duration, "Evento Nuevo CalDav4j");
  cdm.addEvent(nve, null, MyUid);

  /* Fine so far, I can see the event on bedework web interface (and
through lightning too)

  /////////////////////////////////////////////////////////

  System.out.println("Voy a modicar el evento..");
  // modify event
  System.out.println("--Voy a por el calendar..");

  Calendar pippo =  cdm.getCalendarForEventUID(nve.getUid().getValue());

  /* Not get here yet. Null pointer exception above */

  System.out.println("Master event..");
  VEvent ve = ICalendarUtils.getMasterEvent(pippo,MyUid);

  System.out.println("Cambio el sumario");
  ICalendarUtils.addOrReplaceProperty(ve, new Summary("I changed the
summary!"));
  System.out.println("Voy a actualizar..");
  cdm.updateMasterEvent(((HttpClient) cdm.client),ve,null);

 }

The error is

Which java version are you using?

Original comment by robipo...@gmail.com on 17 Apr 2009 at 11:44

Caldav4j requires Java 1.6

Hi,

I'm also facing the same problem. Add event works fine, but as instruction :
Calendar pippo =  cdm.getCalendarForEventUID( ((HttpClient
cdm.client),nve.getUid().getValue() );

execute it throws:

Exception in thread "main" 
org.osaf.caldav4j.exceptions.ResourceNotFoundException: Could not find resource 
for the UID 'my_id'
at 
org.osaf.caldav4j.CalDAVCalendarCollection.getPathToResourceForEventId(CalDAVCal
endarCollection.java:587)
at CalDavCollectionManager.main(CalDavCollectionManager.java:398) 

Please help me out from this problem.

Also if i tried to retrieved calendar using getResponseBodyAsString() it works 
fine but as i changed it to getReaponseBodyAsCalendar() it again throwing 
exception saying
Content type expected text/calendar. Was text/html....

Now what i can do to solve this????????
