flex browser application initialization

Question

Would anyone be able to point out some good tutorials on creating applications in flex that are don't have UI's?

Actually, it looks like all I really need to know is how to call a function upon initialization of the flash object. I tried the creationComplete attribute, but it doesn't work in browser.

Well, I'm not sure what made it work finally, but I ended up copying and pasting this code from some website (sorry, i don't remember the site):

<?xml version="1.0" encoding="utf-8"?>
<!-- wrapper/CheckExternalInterface.mxml -->
<s:Application 
    xmlns:fx="http://ns.adobe.com/mxml/2009" 
    xmlns:mx="library://ns.adobe.com/flex/mx" 
    xmlns:s="library://ns.adobe.com/flex/spark" 
    creationComplete="initApp()">
</s:Application>

And that ended up working! thanks anyway.

If you're intent is to connect JavaScript to a Java Server, why not use XMLHTTPRequest ? IT is the basis of every AJAX style RIA application. The data format you pass back and forth can either be JSON or XML. It doesn't have to be binary.

Second, you don't need Flex for this. The Sockets APIs in ActionScript and are part of the Flash Player. You can use them without any dependencies to the Flex Framework.
