From the previous article you learned how to build an SWC file.
Next Step is to build the MXP for the Adobe Extension Manager to install the component which you have made(SWC). Abobe Extension Manager allows you to create MXP file with the help of MXI file, MXI is nothing but, it is a simple XML file which contains some informations about the compoent. Like, Author Name, Component Name, Version, Description, Files etc.
Ok, lets start with the help of some screens.
Create the MXI as shown below and save it as you componentName.mxi. (Note: Please make sure that your swc file is in path that mentioned in MXI file)
MXI XML file:
<?xml version="1.0" encoding="UTF-8"?> <macromedia-extension name="Square Box" version="0.1" type="component" requires-restart="true"> <author name="Midhun Devasia" /> <products> <product name="Flash" version="9" primary="true" /> </products> <description> <![CDATA[This is a sample component. TutorBoy.com]]> </description> <!-- Describe where the extension shows in the UI of the product --> <ui-access> <![CDATA[Acces the component via Components > YourComponents Etc. ]]> </ui-access> <!-- Describe the files that comprise the extension --> <files> <file name="SquareBox.swc" destination="$flash/Components" /> </files> </macromedia-extension>
Open the Abobe Extension Manager and goto File->Package Extension
Open the MXI file

The the Extension Manager Automatically convert the MXI file as MXP and it will ask where you want to save it.
