This handler makes a SOAP call (using Savon) to the SharePoint Web Services to create a new event in a SharePoint calendar. After configuring Savon to work with the given account credentials, a few inputted values are checked for validity while the time parameters are configured so that SharePoint will recognize them. Next, the Batch XML structure is built to give the Web Service the information it needs to create the new event, which is then passed via a SOAP call to SharePoint, where the event is created on the specified calendar. Any errors that occur during this process will be caught and re-raised by the handler. Authentication is done through SSL, so the SharePoint site being accessed needs to be setup to allow SSL connections.
Make sure the SharePoint Web Services database is turned on.
