Now that we have the Flex client side of the code, let’s take a

look at what we need on the server.

The Server Code in ColdFusion

You can write the server code in whatever server technology

you like (e.g., PHP, Java, Rails, etc.). I’ve chosen to use Cold-

Fusion here, but you can find the code for the other server

models on the O’Reilly web page for this book.

The ColdFusion version of the text return page appears in

Example 5-5.

Example 5-5. PlainHttpService.cfm

<cfinvoke component="Shipping"

method="getShippingOptions" argumentcollection="#url#"

returnvariable="myResult" />

<cfoutput>#myResult[i].service#: #dollarFormat

(myResult[i].price)#<br

/></cfoutput>

</cfloop>

The XML version of the interface appears in Example 5-6.
