Creating an appointment in an exchange calendar using webdav (slide)

[Bernhard Weitlaner]

Hello!

I am new in webdav. I am trying for a long time to create an appointment in
an exchange calendar (pubic folder) using webdav but without success.
I am despairing.
Here my programm:

String strCalendarURI = "http://server/public/test1";
HttpURL hrl = new HttpURL(strCalendarURI);
hrl.setUserinfo("user", "pw");
WebdavResource wdr = new WebdavResource(hrl);

wdr.setDebug(1);
Hashtable props = new Hashtable();
props.put(new PropertyName("DAV:", "contentclass"),
"urn:content-classes:appointment");
props.put(new PropertyName("DAV:", "contentclass"),
"urn:content-classes:appointment");
props.put(new PropertyName("http//schemas.microsoft.com/exchange",
"outlookmessageclass"), "IPM.Appointment");
props.put(new PropertyName("urn:schemas:httpmail","subject"), "Changed
Test Appointment Subject");
props.put(new PropertyName("urn:schemas:httpmail","htmldescription"),
"Let's meet here");
props.put(new PropertyName("urn:schemas:calendar","location"), "do");
props.put(new PropertyName("urn:schemas:calendar","dtstart"),
"2006-01-01T10:00:00.000Z");
props.put(new PropertyName("urn:schemas:calendar", "dtend"),
"2006-01-01T10:30:00.000Z");
props.put(new PropertyName("urn:schemas:calendar","instancetype"), "0");
props.put(new PropertyName("urn:schemas:calendar","alldayevent"), "0");
props.put(new PropertyName("urn:schemas:calendar","responserequested"),
"1");
props.put(new PropertyName("urn:schemas:calendar","busystatus"), "BUSY");
props.put(new PropertyName("urn:schemas:calendar","meetingstatus"),
"CONFIRMED");
props.put(new PropertyName("header", "to"), "user");
props.put(new PropertyName("urn:schemas:mapi","finvited"), "1");

out.print("returned value ... " + wdr.proppatchMethod(props, true));


The output:

It looks not so bad. But no appointment is created.
Where is the problem?
When i google for the problem i always find howtos for .NET but nearly
nothing for java

Thank you for your help.

best regards

My experience has been that although you can connect to Exchange with
WebDAV, a lot of things don't work the way you'd expect when you just
read about WebDAV. Remember it's Microsoft .

When we developed an Exchange back-end for a SyncML-DS server, we
found that we weren't able to create appointments with PROPPATCH
either. What we finally did was to sniff the WebDAV traffic between
Exchange and an Outlook Web Access (OWA) client. When we saw that OWA
uses POST requests to create new appointments, we did the same.

BTW, we also used the WebDAV client from Jakarta Slide, but quickly
found the standard WebdavResource behaviour didn't correspond to our
requirements and stopped using it. We still profited a lot from
Slide's implementations of all WebDAV methods and of course from the
excellent HttpClient base.

Hello Erich!


Thank you for your answer.
I was worry about that microsoft has their own standards once again.

I need only one function of the webdav protocol. And that is to insert
an appointment into a calendar.

You said that you tried it with the PUT method. Does that work?
Maybe do you have a small code sample?
That would be great.

Thank you very much.

Bernhard

Hello Erich!

Ok, that will make things easier.

Not a PUT, but a POST. In addition to your regular WebDAV properties,
add a property "Cmd" with value "saveappt" (which in OWA is part of
the form).

Maybe do you have a small code sample?
That would be great.

Something like:

PostMethod post = new PostMethod("/exchange/calendar");
post.addParameter("Cmd", "saveappt");
post.addParameter("urn:schemas:calendar:dtstart", "20060126T160000Z");
....
try {
httpClient.executeMethod(post);
} catch (IOException e) {
...
}

To be honest there are a few things missing (like getting the
httpClient), but you can look up most of these things in the source of
the WebdavResource class.

Thank you very much.

regards,
Bernhard

I hope this helps.

Thank you very much.

Bernhard

 

[Ken]

How did you make it? I am working on something like yours, could give
me some hints?
Thanks in advance~

 

[ekor_hitam]

Hi,

I have created an appointment using a POST.

Now I would like to know the uid of the appointment just created.

Have you already found a way to get this?

Regards,

Ekor.

Creating appointment no longer works with Exchange 2007

I have been using Post to create an appointment, but now we have upgraded to Exchange Server 2007 and this no longer works. Any ideas or suggestions?

 

[RatStrydom]

Hi,

I have been struggling with the same issue of getting a success (201) response, but no appointment appearing (although I have been using .Net).

I finally found that adding the following request header "Translate: f" fixed my problem. This seems to be left out in the MSDN articles.

I didn't end up needing to add any post parameters.

I hope this helps someone.

There is Java API: JWebDAV for Exchange
