ChannelConnect Failed. error null

RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" faultDetail="Channel.Connect.Failed error null"]

Hi folks - I've been succesfully able to get RPC services running. However, when I try to run a simple FDS example, I get the following error :

RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" faultDetail="Channel.Connect.Failed error null"]

My mxml code is given below :

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="playaservice.fill(players)">

<mx:DataService id="playaservice" destination="PlayerAssembler"/>

<mx:ArrayCollection id="players"/>

<mx:Panel title="Get Players">
<mx:DataGrid id="playergrid" dataProvider="{players}" editable="true">
<mx:columns>
<mx:DataGridColumn dataField="firstName" headerText="First Name"/>
<mx:DataGridColumn dataField="lastName" headerText="Last Name"/>
</mx:columns>
</mx:DataGrid>
</mx:Panel>
</mx:Application>

My data-management config file looks like this :

I am using Tomcat. With the same services-config.xm file, I've been able to get simple RPC services working. But I am unable to get a simple FDS working.

My Java Assembler class looks like this:

public class PlayerAssembler
extends AbstractAssembler {

public Collection getPlayers() {
System.out.println("Filling players");
PlayerService playerService = new PlayerService();
return playerService.getPlayersAsList(); // This just returns a list of Player objects. Player is a simple Java class.
}

}

Does my error message have anything to do with RTMP protocol ?

I see that data-management-config.xml has 'my-rtmp' as the default channel.
<default-channels>
<channel ref="my-rtmp"/>
</default-channels>


When I look for my-rtmp in the services-config.xml, I see the following reference
<channel-definition id="my-rtmp" class="mx.messaging.channels.RTMPChannel">
<endpoint uri="rtmp://{server.name}:2037" class="flex.messaging.endpoints.RTMPEndpoint"/>
<properties>
<idle-timeout-minutes>20</idle-timeout-minutes>
<client-to-server-maxbps>100K</client-to-server-maxbps>
<server-to-client-maxbps>100K</server-to-client-maxbps>
</properties>
</channel-definition>

I am curious - when I type rtmp://locahost:2037/ I get the following error "rtmp is not a registered protocol

Could this in anyway be related to the 'ChannelConnectFailed" problem ?


Please help.

Thank you.
