BlazeDS Messaging Channel.Connect.Failed Error

问题

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:

                       xmlns:s="library://ns.adobe.com/flex/spark" 
                       xmlns:mx="library://ns.adobe.com/flex/mx">

            import mx.messaging.messages.AsyncMessage;

            protected function cons_faultHandler(event:MessageFaultEvent):void
            {
                trace(event.message + ' fault')
            }

        ]]>

    <fx:Declarations>

    </s:VGroup>

</s:WindowedApplication>

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

        </channel-definition>
    </channels>

    <logging>

        </target>
    </logging>

    <system>
        <redeploy>
            <enabled>false</enabled>
        </redeploy>
    </system>

</services-config>


<?xml version="1.0" encoding="UTF-8"?>
<service id="message-service" 
    class="flex.messaging.services.MessageService">

    <adapters>
        <adapter-definition id="actionscript" class="flex.messaging.services.messaging.adapters.ActionScriptAdapter" default="true" />

    </adapters>

    <default-channels>

    </default-channels>

    <destination id="cricket">
        <channel ref="my-amf"/>
    </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

回答1:

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.
