Javascript - Flash Sound Recording

I would like to capture sound from a browser and send it to a server. I decided to use red5 for the reasons listed on this interesting page that claims to do exactly what I need.

It requires the following:

• A running red5 server
• A flash object that can capture the microphone input
• A JavaScript controller

I tried to implement this example localy (I pretty much simply copied all the files). At page load from my server console I can see that the supplied flash object audioRecorder1.swf creates a connection.

[INFO] [NioProcessor-1] org.red5.server.net.rtmp.codec.RTMPProtocolDecoder - Action connect [INFO] [NioProcessor-1] org.red5.server.net.rtmp.RTMPHandler - Connecting to: [WebScope@4799a84f Depth = 1, Path = '/default', Name = 'oflaDemo']

But when I hit any button (record/play/stop) of the controller, I'm having this javascript error from which I can't figure out the origin

thisMovie("denRecorder").jsRecord is not a function

denRecorder is the id of the flash object in the page (created with the swfobject.js library)

<object width="1" height="1" type="application/x-shockwave-flash" id="denRecorder" name="denRecorder" data="/static/flash/audioRecorder.swf">
  <param name="menu" value="false">
  <param name="flashvars" value="myServer=rtmp://localhost/oflaDemo&amp;mySound=snd_881881开发者_JAVA百科60112&amp;myDuration=0">
</object>

I have created a package that can be tested localy.

Do you have any idea of what is my problem ?
