The rest of this page features two running versions of the Shipping Costs application. Try them out; they are not screen shots.

The plain text sample application

The following application shows an embedded application created using Flex Builder. Type a 5-digit zip code, like 80401, and a shipping weight, like 3, into the text boxes and click the Get Shipping Options button to retrieve and display the plain text data in a text box.

The XML sample application

The following application shows an embedded application created using Flex Builder. Type a 5-digit zip code, like 80401, and a shipping weight, like 3, into the text boxes and click the Get Shipping Options button to retrieve and display the XML data in a grid.
