RPC Fault

[russell42]

Hi,

I've been playing around with BlazeDS and Spring and I've been following Christophe Coenraets tutorial on the Adobe website.

One thing that doesn't seem to be covered though is the "my-amf" configuration. My Flex front-end cannot seem to communicate with the back-end through remote objects.

I think it's because there's a 404 error occuring when it tries to access http://localhost:8080/myapp/messagebroker/amf. The directory doesn't exist in my project consequently it doesn't appear when Tomcat expands the war file.

The actual error displayed in the Flash debugger in the browser is:

[RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" 
faultDetail="Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Status 404: url: 'http://localhost:8080/myapp/messagebroker/amf'"]

at mx.messaging.channels::AMFChannel/mx.messaging.channels:AMFChannel::statusHandler()

Does anyone know what the problem could be?

Thanks!

Few things no notice:

1) have you done your project like the reference says: http://static.springframework.org/sp...tml/index.html ?

2) If so, have you created the channelset manually? BlazeDS needs it.

If I remember right, the Adobe example was the old way doing this.

Thanks for the reply Durden.

I looked at the Spring documentation but it seemed incomplete as it's quite short, the article that I followed is here: http://www.adobe.com/devnet/livecycl...ds_spring.html

Do you have any more information on creating channel sets? I'm not familiar with that.

Edit: Is creating the channel sets something that is done in XML like the following in services-config.xml:

<channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel">
    <endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf" class="flex.messaging.endpoints.AMFEndpoint"/>
    <properties>
        <polling-enabled>false</polling-enabled>
    </properties>
</channel-definition>

Thanks!

For creating channel sets, see: http://forum.springframework.org/sho...5&postcount=18

That Adobe article does not use the current Spring BlazeDS integration, so you should read the reference carefully, if you want to use it.

Ah I see, thanks very much.
