The sample services-config.xml file is located in the C:\fds2\resources\config folder, and
the web application flex-messaging-service.xml file is located in the
C:\fds2\jrun4\servers\default\samples\WEB-INF\flex folder when you install Flex in the
default location.
(Optional) Turn on the ColdFusion-specific debugging output in the Flex console by

adding the following <pattern> tag in the <filters> tag in the <logging> section of the web

The ColdFusion MX Administrator lets you enable or disable Flex Data Management
support. If you are running more than one instance of ColdFuison, you must use a unique
ID to specify each instance of ColdFusion for which you want to enable Flex Data
Management support. You do so by specifying the identity in the <identity> element of the
data-management-config.xml file.
Writing the ColdFusion CFCs
The Flex Data Management Service recognizes the methods:
The method retrieves records from a database and populates an array with the records.
fill
The method retrieves a specific record. The
get
synchronization conflicts by accepting a change list, which is an array of change objects. The
method returns a number that indicates how many records are in a result set. To
count
perform any of these database tasks, the Flex application calls the appropriate
, or method in the assembler CFC. You can also use a
sync count
which checks whether to update the results of a fill. For more information, see
fills" on page 43.
When you create the ColdFusion CFC, you include the database manipulation in the
methods in the assembler CFC or use the Bean/DAO methodology. For more information,
see "Selecting a methodology" on page
