BlazeDS Messaging Channel.Connect.Failed Error - apache-flex

Question

I searched through the internet and any answer for this error could not solved my problem.
I have a blazeds server in Openshift and I'm connecting to it via Flash Builder.
I want to make an app that will send a message to all other users who are using my app.
I mean I have 2 applications. One will send a message to server and this one will be on Desktop, the other one is a mobile project and will receive messages that I sent from desktop app through server.
I tried to use BlazeDS messaging but it's giving me this error:

This is my desktop application that I'm trying to send messages from:

And this are my messaging-config.xml and services-config.xml:

</adapters>
<default-channels>
<channel ref="my-polling-amf"/>
</default-channels>

</destination>
</service>
I don't know what I'm doing wrong and why in error message, the endpoint url is "http://ainApp.swf/messagebroker/amfpolling". My desktop apps name is MainApp by the way.
Thanks

In services-config.xml you should define your channel url.
url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf"
to like this
url="/yourContextRootName/messagebroker/amf"
Do not define server.name and server.port, it comes with similar problem.
