Summary: This series describes and shows you how to extend WebSphere Portal Personalization capabilities to make data from external sources available to your portal using Personalization rules.
In Part 1, you learned the fundamentals for working with external data and Personalization rules.
In Part2, you built a simple application object to and used that object's attributes to decide when to show and hide a portlet.
In this part, you work through a more advanced scenario that uses a Web service to obtain data values for the application object. You use those values to show or hide a portlet depending upon the weather conditions in a user's area.
