How to upload images from a URL using Java SDK?

Detailed Description

  This sample illustrates the use of Java SDK  to upload images from a URL on an external web server. The required steps are:

  1. Register EPS server URL in ApiContext object and  the String array object of the image URLs 

  2. Set the ExternalPictureURL with the image URL string array in UploadSiteHostedPicturesRequestType object.
