Re: CMIS Java Class connection to Microsoft SharePoint 2013 - Unauthorized

Hi Matheus,

I don't believe it's a SharePoint problem if you can connect with CMISWorkbench.The Workbench basically calls the some methods with the same sessionparameters that you are using in your code.


Check the URL ("host" in your code) again. It must look like this:
http://<server:port>/_vti_bin/cmis/rest?getRepositories

Also check if you are choosing the right repository.

Your code always picks the first repository ("Repository repository =repositories.get(0);"), but that might not be a document library.

I really think that the problem is on my SharePoint or it's server
configuration. The authentication variables are not wrong.
The getErrorContent returned "null", and a toString of it only show me
the same return (org....: Unauthorized).

With this same code, I can connect to Alfresco repositories.
This is really taken my sleep.

Florian (and everyone else),

   Would you mind taking a look at my class? It's not huge nor
complex, only the basic code to connect and get content.

   If you have the time, it's on
http://paste.ofcode.org/pSDkwa92tU9UvTAUpRK3aY. I've purposely removed
the credentials on it. Don't mind the Adobe imports or classes also,
it's for me to be able to use this class as a component inside an
Adobe software.

    The main methods I'm trying to make work now are listFiles (and,
consequently, connect).

Thanks.

Hi Matheus,

We connect to SharePoint repositories all the time via CMIS. And the
CMIS Workbench uses exactly the same libary that you are using in your
program. If the CMIS Workbench can connect, your program can connect.

Check the URL, the user and the password again. These are the only
variables.

You can also catch the CmisUnauthorizedException and call the
getErrorContent() method. It returns the error message sent by the
server. It might or might not be something helpful.

Florian,

   Again, thank you for the answer, but unfortunately that didn't
solved the problem.
   Bellow the parameters that I used:

                         //Authentication and binding parameters
                       parameter.put(SessionParameter.USER, user);

parameter.put(SessionParameter.PASSWORD,password);parameter.put(SessionParameter.ATOMPUB_URL,host);

                       parameter.put(SessionParameter.BINDING_TYPE,
BindingType.ATOMPUB.value());

                       //Parameters as in OpenCMIS WorkBench

parameter.put(SessionParameter.AUTH_SOAP_USERNAMETOKEN, "true");parameter.put(SessionParameter.AUTH_HTTP_BASIC,"true");parameter.put(SessionParameter.COMPRESSION,"true");parameter.put(SessionParameter.CLIENT_COMPRESSION, "false");parameter.put(SessionParameter.COOKIES,"true");


                       //Workaround parameters

parameter.put(SessionParameter.OMIT_CHANGE_TOKENS, "true");parameter.put(SessionParameter.ADD_NAME_ON_CHECK_IN, "true");


   However, the results are the same:


org.apache.chemistry.opencmis.commons.exceptions.CmisUnauthorizedException:
Unauthorized

    Again, I'm trying to connect to a SharePoint 2013 server (that I
sucessfully connect using OpenCMIS Workbench). All the parameters the
Workbench show me in the expert dialog I've already copied into my
code... Also, there is no proxy configuration.

     Anyone ever tried this kind of connection? Any more workaround I
could try?

Thanks everyone in advance,

Hi Matheus,

If you can connect with the CMIS Workbench, try the following.

* Connect with the CMIS Workbench.

* Return to the Login dialog and select the Expert tab. Here youshould

find the session parameters that were used for this connection.
* Take these session parameters and use them in your Java program.
* If that works, play with the parameters. You probably don't need all
of them for a successful connection.
* If that doesn't work, check if you need additional proxy settings.
The
CMIS Workbench tries to figure them automatically, but your program
doesn't.


When everything works fine, also add the following session parameters:

org.apache.chemistry.opencmis.workaround.omitChangeTokens=true
org.apache.chemistry.opencmis.workaround.addNameOnCheckIn=true

They enable workarounds for bugs in the SharePoint CMIS connector.

Hello guys.


Again I send you a message to get some help developing with Apache
Chemistry.


So, I got this project where I try to connect to a SharePoint 2013
server using CMIS and to get/"upload" files there.


After the help of Sascha Homeier here on this list, I solved some
problems and my project now works with the public Alfresco CMIS

services and a instance of Alfresco I have on my environment.However,

when I try to use it on SharePoint 2013, I got some problems.


So, my code for connection is:


Session session = CMISServicesImpl.connect(strHost, strUser,
strPassword);

Folder root = session.getRootFolder();
         ItemIterable<CmisObject> children = root.getChildren();
         System.out.println("Found the following objects in the root
folder:-");
         ArrayList documentsArray = new ArrayList();
         for (CmisObject o : children) {
         documentsArray.add(o);
             System.out.println(o.getName() + " which is of type " +
o.getType().getDisplayName());
         }

Basically, the code we all can get on the getting started examples on
the Chemistry webpage.
When trying to connect to a SharePoint 2013 that have the CMIS
enabled, as well as basic authentication (I can, for example, connect
to this repository via CMISSync - a CMIS open source client - or

Apache Chemistry CMIS Workbench without problems, so the issue arenot

the credentials or the url), I get the following exception:

org.apache.chemistry.opencmis.commons.exceptions.CmisUnauthorizedException:
Unauthorized

I think that this is something in the communication of my application

with the SharePoint server... This is a common problem for peoplethattry to connect to SharePoint using CMIS on webpages, but there arenot

answers on theses pages...

Another important information: I do this connection using https and
the server does have a valid certificate.

Also, if I try the same connection inserting a proposital error onthe

url (like a letter where it should be not), the error changes, what
tells me that if I get this "Unauthorized" error, my application are
communicating with the SharePoint and the credentials/url data are
correct.

Anyone here know how can I solve this, or at least understand this
problem better? Any tip or hint?

Thanks all you guys again,
