DEVELOPING COLDFUSION 9 APPLICATIONS
Flex and AIR Integration in ColdFusion

Using the LiveCycle Data Services ES Assembler

To use Adobe ColdFusion as the back-end data manager for an Adobe Flex application, you use the Adobe LiveCycle
Data Services ES assembler. You configure the LiveCycle Data Services ES assembler and write an application that uses
the assembler.
To use LiveCycle Data Services ES with ColdFusion, you have to be familiar with ColdFusion components; accessing
and using data in ColdFusion applications; and using LiveCycle Data Services ES.
About ColdFusion and Flex
ColdFusion 9 supports LiveCycle Data Services 2.6.1 however the ColdFusion installation does not provide the option
to install LiveCycle Data Services. You need to manually install LiveCycle Data Services to use it with ColdFusion. For
more information about manually installing LiveCycle Data Services, see Installing LiveCycle Data Services Manually
in the Installation Guide.
By default, ColdFusion installs BlazeDS which provides messaging support in ColdFusion.
For more information about the changes in using Flash Remoting, see Changes in the XML configuration files for
Flash Remoting in ColdFusion 9 and ColdFusion 9.0.1.
The LiveCycle Data Services ES assembler lets you use ColdFusion components (CFCs) to provide the back-end data
management for a Flex application that uses the Data Management Service. You can run LiveCycle Data Services ES
as part of ColdFusion or remotely. If you are running LiveCycle Data Services ES as part of ColdFusion, LiveCycle Data
Services ES and ColdFusion communicate directly. If you are running LiveCycle Data Services ES remotely, LiveCycle
Data Services ES and ColdFusion communicate by using RMI. The following diagram shows how ColdFusion and
LiveCycle Data Services ES interact in both cases:
Note: To use the LiveCycle Data Services ES assembler, the Flex application must be running on Flex Data Services 2.0.1
or LiveCycle Data Services 2.5, although not every feature is supported in Flex Data Services 2.0.1.
The Flex server includes a ColdFusion Data Service adapter. The adapter processes changes to data to ensure that data
on the client is synchronized with back-end data and conversely; it executes the , , and
sync fill count, get
operations, identifies conflicts, and passes results to LiveCycle Data Services ES.
ColdFusion includes the LiveCycle Data Services ES assembler; along with the ActionScript translator, it converts the
input arguments where necessary and translates the return values.
Note: If you install LiveCycle Data Services ES, ColdFusion does not map .SWF files. This means that all .SWF files are
served through the ColdFusion web application instead of the web server.
