Adobe Developers of Greater Orlandohttp://adogo.usAugust 2007

Developing a service layer that can be used by Flex, Ajax and ColdFusion.

What's this ColdSpring thing?● Most used ColdFusion

framework.● Used for managing

your dependencies of CFCs.

● Can be used with other frameworks like Fusebox, Model-Glue or Reactor.

● Inversion of Control, Aspect Oriented Programming

Why use ColdSpring?

● Better control over your objects

● Simplifies Object Creation

● Enforces good practices

● Lots of free features● Single config file● Offers a single

extension point

Application Design Goal

● Offer a single point of extension for any external services.

● Be able to easily extend our application for new mediums.

● Need ability to alter behavior and return types for different extension points.

● Complete division between the view and the model.

Application Example?

Flex ColdFusion Ajax

ServiceManager

UserService ProductService CartService

Little Problem

● All services can't use the same data.● Need a way to extend the service manager and add

specific rules for each external system.● The solution, ColdSpring Remoting!

Adjusted Application Design

Flex ColdFusion Ajax

ServiceManager

UserService ProductService CartService

FlexDelegateFlexDelegate AjaxDelegate

How does that Work?

● Code example

Thanks!
