Article: Getting Started With SharePoint Web Services

| by James Vastbinder Follow 0 Followers on Feb 06, 2008. Estimated reading time: less than one minute |

In this InfoQ exclusive article Trent Swanson provides an overview of  Microsoft Office SharePoint 2007 and its architecture.  In SharePoint, developers can use RPC which provides a more robust object model than web services however it does not support remote operations.  This is where web services must be utilized to support remote operations and gain interoperablity capabilities.

A solid understanding of IIS and ASP.NET is important when developing any SharePoint based solution.  Trent provides examples that walk through both .NET and Java in this introductory article on working with SharePoint web services.

WSRP by A A

Hi,
does Sharepoint support WSRP ? since I'd found any official resources about sharepoint interop through WSRP.

XSD files by Garth Sweet

Very helpful article!
In the article you mention under the "Download the XSD files" section that we can "Download the XSD files from <here>...." but <here> isn't actually a link to anything. Can you point me to the XSD files?

NTLM Authentication by Steve Reynolds

Diana,
Thanks for posting the code. I have been trying to connect to the SharePoint Search Web Service via Axis2, but can not get it to work with NTLM Authentication. I am getting a similar error with your method: Exception in thread "main" com.sun.xml.internal.ws.client.ClientTransportException: request requires HTTP authentication: Unauthorized
I was wondering if any has tried this with NTLM Authentication. The SharePoint server I am connecting to has Basic Authentication turned off because it sends the credentials in plain text. Note: I provided a valid administrator username and password in Main.java. Looking at the BindingProvider API, I don't see any other properties that I need to provide. I'm out of ideas.

Hey,

String host = "moss.syddev01.mymachine.com";
// NOTE: Important to ensure fully qualified domain name is used
String domain = "syddev01";
String realm = "syddev01";
int port = 80;

// Configure authenticator
HttpTransportProperties.Authenticator auth =
new HttpTransportProperties.Authenticator();
auth.setUsername(username);
auth.setPassword(password);
auth.setDomain(domain);
auth.setHost(host);

// Ensure NTLM authentication used
List authPrefs = new ArrayList(1);
authPrefs.add(AuthPolicy.NTLM);
auth.setAuthSchemes(authPrefs);


// Get stub
ListsStub lists =
new ListsStub("http://moss.syddev01.mymachine.com/_vti_bin/Lists.asmx");

// Set authenticator
lists._getServiceClient().getOptions().setProperty
(org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE, auth);
// Get request and execute
GetListCollection req = new GetListCollection();
GetListCollectionResponse res = lists.GetListCollection(req);
DisplayResult(req, res);

Thanks but there should be another c# class, that is missing : Microsoft_Query_Request.c
This class is different from the generated xsd classes & is a wrapper class that the author refers to & the author says it is included in the xsd zip file ...
though i maybe wrong on this;

Re: NTLM Authentication by Kathryn Steel

I have tried this in Java and failed to get it to work with our server.
I can get basic-authentication working but we need to get at least basic authentication with SSL or NTLM working.
For SSL I get an
java.lang.RuntimeException: Object reference not set to an instance of an object.
Which suggest an object not populated that .NET is expecting.
Code:
I changed the URLS to be https:// for the ListsStub()


Authenticator auth = new Authenticator();
ArrayList authSchemes = new ArrayList();
authSchemes.add(AuthPolicy.BASIC);
auth.setAuthSchemes(authSchemes);
auth.setAllowedRetry(false);

auth.setUsername("doman\\name");
auth.setPassword("password");
auth.setPreemptiveAuthentication(true);

copyStub._getServiceClient().getOptions().setProperty(HTTPConstants.AUTHENTICATE, auth);


With NTLM I get Unable to respond to any of these challenges: {basic=Basic realm="melwwsinr08-basicauth"}
org.apache.axis2.AxisFault: Transport error: 401 Error: Unauthorized

code
HttpTransportProperties.Authenticator auth = new HttpTransportProperties.Authenticator();
auth.setUsername("ksteel");
auth.setPassword("object123#");
auth.setDomain("nt3gwm01");
auth.setHost("10.16.224.86");
auth.setRealm("");

// Ensure NTLM authentication used
List authPrefs = new ArrayList(1);
authPrefs.add(AuthPolicy.NTLM);
auth.setAuthSchemes(authPrefs);
//
copyStub._getServiceClient().getOptions().setProperty(HTTPConstants.AUTHENTICATE, auth);

Has anyone got working for SSL or can help further with NTLM ?

Re: NTLM Authentication by Kathryn Steel

Sorry I should also say for SSL I have set up
System.setProperty("javax.net.ssl.keyStore", "c:/client.keystore");
System.setProperty("javax.net.ssl.keyStorePassword", "test12");
System.setProperty("javax.net.ssl.keyStoreType", "JKS"); // JKS or PKCS12 ?

System.setProperty("javax.net.ssl.trustStore", "c:/client.keystore");
System.setProperty("javax.net.ssl.trustStorePassword", "test12");
System.setProperty("javax.net.ssl.trustStoreType", "JKS"); // JKS or PKCS12 ?
System.setProperty("javax.net.debug", "ssl");
And I can see the SSL debug happenning and the application data content type 23 going over the wire encrypted but it gets an error. as I said saying Object reference not set to an instance of object coming back.

Re: XSD files by ian smith

Does anyone know how the four XSD files were generated? Were they reverse engineered, or is this information available in a public place? I'm looking to interoperate with several sharepoint services using Java/JAXB.

org.apache.axis2.AxisFault: Transport error: 401 Error: Unauthorized by Stefaan Somers

I'm pulling my hairs out for the moment. I've written some code, to get a list of sharepoint-lists. For some sharepoint sites, it works without any problem. But for other I always get the error : org.apache.axis2.AxisFault: Transport error: 401 Error: Unauthorized.

There are 2 important questions I have :
- how can I check which authentication mechanism is used (NTLM or BASIC)
- can I get a more clear response, indicating me where the problem lies. Unauthorized is a bit too general. Moreover with the same user-name & password I can open the sharepoint URL for the list webservices.

If anyone wants I can send the jar-file so he can try out for himself. I create a test-sharepoint side, where you can work on.

Any help would be most welcome

Very useful article. Thanks.
Also, can you explain, how these XSD files were generated? Or can we get them from sharepoint server?

Hi Aladin

I had the same problem and solved it by enabling Basic Authentication for the WebApplication in the central administration (Application Management -> Authentication Providers).

Re: XSD files by David Dudok de Wit

Hey Peter, I've covered your authentication problem in my tutorial that you will find here:
Reading a SharePoint list with Java: tutorial.

Basically the workaround to a lot of authentication problems (NTLM, SSL, ...) is to use a local copy of the WSDL file to generate stubs (just save it from your browser). After that, the Web Services just use a simple login/password problem.

I hope this helps.

Cheers,
David D.

Re: org.apache.axis2.AxisFault: Transport error: 401 Error: Unauthorized by Peter Trein

Did you ever get the response for your post? I'm having the same problem.
NTLM authentication fails with org.apache.axis2.AxisFault: Transport error: 401 Error: Unathorized.
The question is: I have a user in a domain DOMAIN\user and the server is on port 8888. how to put it in the code because I believe this is a source of the problem?
My code:

import java.rmi.RemoteException;
import java.util.ArrayList;
import java.util.List;
import com.microsoft.schemas.sharepoint.soap.*;
import org.apache.axis2.AxisFault;
import org.apache.axis2.Constants;
import org.apache.axis2.client.Options;
import org.apache.axis2.transport.http.HTTPConstants;
import org.apache.axis2.transport.http.HttpTransportProperties;
import org.apache.commons.httpclient.auth.AuthPolicy;

public class Test {

public static void main(String[] args) {
HttpTransportProperties.Authenticator auth = new HttpTransportProperties.Authenticator();
auth.setUsername ("user");
auth.setPassword ("pass");
auth.setDomain ("DOMAIN");
auth.setHost("host");
auth.setPort(8888);
auth.setRealm(null);
auth.setPreemptiveAuthentication(true);
List<String> authPrefs = new ArrayList<String>(1);
authPrefs.add((String)AuthPolicy.NTLM);
auth.setAuthSchemes(authPrefs);
ListsStub lists;
try {
lists = new ListsStub();

lists._getServiceClient ().getOptions().setProperty (HTTPConstants.AUTHENTICATE, auth);
Options options = lists._getServiceClient().getOptions();
options.setSoapVersionURI(Constants.URI_SOAP11_ENV);
ListsStub.GetListCollection req = new ListsStub.GetListCollection();
ListsStub.GetListCollectionResponse res;
System.out.println();
res = lists.GetListCollection (req);
System.out.println(res.toString());
} catch (AxisFault e) {
e.printStackTrace();
} catch (RemoteException e) {
e.printStackTrace();
}
}
}

Re: QueryOptions by Leonid Sokolin

Can anyone provide an example of how to specify QueryOptions in the request?

I need to get a list of subfolders and it is apparently possible, if Folder option is specified as follows:

I am not sure though how to assign this value to GetListItems.QueryOptions.

I can only get wsdl file from sharepoint server.

main.java
bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "http://myserver/_vti_bin/search.asmx"); //okay, got result

// bp.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "http://myserver/_vti_bin/spsearch.asmx"); //Server Status: ONLINE Response Status: ERROR_NO_RESPONSE
