The Flex application, which is running on the customer’s com-

puter,

uses the HTTPService tag to talk directly to the web serv-

er. The code on the web server, either in PHP, ASP, JSP, or

something similar, talks to the database and then returns either

text or XML.

Example 5-3 shows the code for the Flex application which

responds to a text response from the web server.

Example 5-3. The text-based Flex application

<?xml version="1.0" encoding="utf-8"?>
