About the Flex coding process 61
The following table describes the Flex development tools:
You can get additional information about Flex applications during the development process using
a set of query string parameters. You append these to the end of the request string, as the
following example shows:
http://localhost:8700/flex/MyApplication.mxml?debug=true
To use most of these query string parameters, you must disable production mode in the flex-
config.xml file by setting the value of the
<production-mode>
tag to
false
.
Tool Description
Macromedia Flash Debug Player Flash Debug Player is a Flash Player that reports runtime errors,
including errors for undeclared variables, uncaught runtime
exceptions, and operating-system–specific networking errors.
You can view errors in a trace window and send errors to a text
file.
When you run Flash Debug Player, you specify the subsystems
to monitor and request the compiled SWF file, through the Flex
server.
To use the Flash Debug Player, you must disable production
mode if it is enabled and edit debugging settings in the flex-
config.xml file. For more information, see Chapter 36,
“Debugging Flex Applications,” in
Developing Flex Applications .
command-line debugger The Flex ActionScript debugger lets you step into and debug
ActionScript files used by your Flex applications.
To use the command-line debugger, you must disable
production mode if it is enabled and edit debugging settings in
the flex-config.xml file. For more information, see Chapter 36,
“Debugging Flex Applications,” in
Developing Flex Applications .
compc The compc utility generates a SWC file from MXML component
source files and/or ActionScript component source files.
mxmlc The Flex command-line compiler, mxmlc, is useful if you want to
request SWF files in a web browser or in Flash Player. It is
particularly useful for debugging SWF files with Flash Debug
Player.
For more information, see Chapter 39, “Administering Flex,” in
Developing Flex Applications .
ActionScript Profiler The ActionScript Profiler monitors ActionScript performance in
Flash Debug Player. It has a JSP-based user interface and also
provides text-based performance reports.
For more information, see Chapter 37, “Profiling ActionScript,”
in Developing Flex Applications
