Skinning The Site

Each web site is “skinned” through LAF and code orlando.hotelscorp.com smokies.hotelscorp.com vegas.hotelscorp.com (coming soon)

All Fusebox code is reusable between destinations Identical process flows Changes to codebase affect all sites at once

Tying the Objects To Fusebox

Main objects stored in the application scope as Singletons

The request scope is your friend JSP forwarding in CFMX Abstracts persistence implementation (i.e.

session, cookie, DB)

Asynchronous Search

Asynchronous Processes/Threads ColdFusion doesn’t allow you to kick off

your own threads Wrote a simple Java object that would

open a URL in a Java Thread and die on completion

Used for asynchronous search in HotelsCorp.com.

<cfscript> // return object that’s brand new function getSomeObject() { return CreateObject(“component”, com.mywebsite.object”); }

</cfscript>

In Fuses, don’t explicitly reference object scope<cfset object = request.objectName>

In Fuse:<cfset object = getSomeObject()>

In Application File:

<cfscript> // return object stored persistently in application scope function getSomeObject() { return application.someObject; }

</cfscript>
