Using the SPServices jQuery library from codeplex or any other javascript based solution is it possible to call a SharePoint 2010 web-service from a standalone HTML page using this library and jQuery? Basically I need to upload a file to a existing Document set but I need to do so from a standalone page. The user will be in a single signon situation and logged in to Dynamics CRM.
Google "spservices outside sharepoint".
Second link is Must the page using SPServices be hosted within SharePoint?
From the SPServices author:
While the pages where you use SPServices don't have to be within SharePoint, it's common to run into authentication issues if they are not. Either SharePoint doesn't know the user's identity or there can be cross-domain scripting issues. There are far too many variations in all of this for me to usually give a yes or no answer.
