Compiling Components With Flex Data Services - Adobe FLEX 2 - CREATING AND EXTENDING COMPONENTS Manual

</mx:Application>
When you distribute SWC files, ensure that the corresponding ActionScript file is not in the
directory structure of the application or in the ActionScript classpath. Otherwise, Flex might
use the ActionScript file, rather than the SWC file.
When you use mxmlc to compile the main application, ensure that the c:\flex\mainApp
directory is included in the library path, otherwise mxmlc cannot locate the SWC file.
For more information about SWC files, see Chapter 9, "Using the Flex Compilers," in
Building and Deploying Flex 2 Applications, and Chapter 10, "Building Projects," in Using Flex
Builder 2.
Distributing a component as an RSL file
You create an RSL by using the compc tool, and then pass the library's location to the
compiler when you compile your application. For more information, including an example,
see Chapter 10, "Using Runtime Shared Libraries," in Building and Deploying Flex 2
Applications.
Compiling components with Flex Data
Services
If you have Adobe® Flex™ Data Services, you can compile your application, and any custom
components, in the same way that you can when using Flex 2 SDK. For more information,
see "Compiling components with Flex 2 SDK" on page 66. Alternatively, you can deploy
your application on your application server, and then compile the application upon an HTTP
request.
To deploy the application on your application server, copy the MXML and ActionScript files
to a web application directory. The first time a user requests the MXML file URL in a web
browser, the server compiles the MXML code into a SWF file. The server then sends the SWF
file to the web browser where it is rendered in Flash® Player. Unless the MXML or
ActionScript file changes, the SWF file is not recompiled on subsequent requests.
Typically, you copy these components to a subdirectory of the WEB-INF directory for the
web application that corresponds to your Flex Data Services application. For example, you
can copy custom ActionScript classes and MXML components to the WEB-
INF/flex/user_classesdirectory.
