Hi,

I want to use SharePoint web service in Apex (e.g List service). I was able to generate Apex code from WSDL file uploaded to Force.com. Below is my current code to access List service hosted on HTTPS server

public String[] getSharePointListIds() {
  MSSharepointSoapClient.ListsSoap soapClient = new MSSharepointSoapClient.ListsSoap();
  // I have username / password to access SharePoint but I don't know how to specify it in generated Apex code so here I just simply ingore it
  MSSharepointSoapClient.GetListResult_element result = soapClient.GetList('Products');
}

I got error in GetList() method on generated code. Below is error message from Debug Log

...

Do you have any experience on this error ? Is there any sample code to access SharePoint web service (with authentication) ?

Thanks,
