Microsoft Sharepoint web service from Java client

[Pin Ping]

I can call the sharepoint web services from java client if sharepoint uses basic authentication.

ServiceSoapStub serviceSoapStub = new ServiceSoapStub(new URL(Service_URL), null);
serviceSoapStub.setUsername(USERNAME);
serviceSoapStub.setPassword(PASSWORD);

result = serviceSoapStub.getListItems(...);

But if sharepoint uses Kerberos authentication, and my java side (WebSphere portal) is also using Kerberos, what should I do to make the web service call?

Have anyone done that? (Microsoft sharepoint web service from Websphere Portal with both Kerberos authentication)

Thanks

I think the issue might be that the client (ServiceSoapStub, etc.) you are using does not know how to talk Kerberos.

I'm not certain but there's probably a way to do it if you search through the websphere docs for words like single-sign on, spnego, wsdl, soap client stub, etc.

There is an open source project on sourceforge that might be of some interest. The project is meant to be a server side project but the library has a stand alone client piece that can be used against any server.

http://spnego.sourceforge.net/protected_soap_service.html

It also has two (a working example) java files that you can compile and try out on your server:

http://spnego.sourceforge.net/SpnegoHelloClient.java
http://spnego.sourceforge.net/ExampleSpnegoSOAPClient.java

Good luck!
