Any help would be greatly appreciated. I've tried pretty much everything that came to my mind and am really stuck right now

Thanks,

How are you setting up your RemotingDestination?  Try turning up the logging level on org..flex.remoting.RemotingDestinat  ionExporter to INFO to verify that the destination is getting created at startup.

Hi Jeremy,

To set up the RemotingDestination, I first added the following annotations to the Java class that hosts the Remoting functions:Code:
@Transactional
@Service(quot;TranslationServicequot;)
@RemotingDestination(channels={quot;my-amfquot;,quot;my-secure-amfquot;})
public class TranslationService {

[...]

}
As this did not work, I've removed it again and tried the following at the end of web-application-context.xml. However, both did not help to solve the problem.Code:
lt;bean class=quot;org.translation.service.TranslationServicequot; id=quot;TranslationServicequot; /gt;
lt;flex:remoting-destination ref=quot;TranslationServicequot; /gt;
I turned up the logging level for the class you described, but nothing has changed at the console output. Is the below the correct syntax to update logging?Code:   lt;logginggt;   lt;target class=quot;org..flex.remoting.RemotingDestinatquot; level=quot;Infoquot;gt;   lt;filtersgt;   lt;patterngt;ionExporterlt;/patterngt;   lt;/filtersgt;       lt;/targetgt;   lt;/logginggt;
Thanks!

It just occurred to me that with the mixed Spring MVC setup you're using, you probably need to set the mapping order for Flex, so that it has a change to handle a given request before the normal Spring MVC @Controller handling:Code:
lt;flex:message-broker mapping-order=quot;1quot;/gt;
As for the logging, no, that looks like the BlazeDS logging config in services-config.xml.  We use commons logging, so you'd either need to configure java.util logging or log4j depending on which implementation is being used.

If setting the mapping-order doesn't do the trick, could we have a look at the code on the client side that you're using to invoked the destination, and perhaps your services-config.xml as well?

My services-config.xml looks like this:Code:
lt;?xml version=quot;1.0quot; encoding=quot;UTF-8quot;?gt;
lt;services-configgt;
   lt;servicesgt;       lt;default-channelsgt;          lt;channel ref=quot;my-amfquot;/gt;       lt;/default-channelsgt;   lt;/servicesgt;
   lt;channelsgt;       lt;channel-definition id=quot;my-amfquot; class=quot;mx.messaging.channels.AMFChannelquot;gt;lt;endpoint ucl=quot;translation/messagebroker/amfquot; class=quot;flex.messaging.endpoints.AMFEndpointquot;/gt;
lt;!-- lt;propertiesgt;
lt;polling-enabledgt;falselt;/polling-enabledgt;
lt;/propertiesgt; --gt;                   lt;/channel-definitiongt;      
lt;channel-definition id=quot;my-secure-amfquot; class=quot;mx.messaging.channels.SecureAMFChannelquot;gt;lt;endpoint ucl=quot;translation/messagebroker/amfsecurequot; class=quot;flex.messaging.endpoints.SecureAMFEndpointquot;/gt;lt;propertiesgt;    lt;add-no-cache-headersgt;falselt;/add-no-cache-headersgt;lt;/propertiesgt;       lt;/channel-definitiongt;   lt;/channelsgt;      lt;logginggt;       lt;target class=quot;flex.messaging.log.ConsoleTargetquot; level=quot;Debugquot;gt;lt;propertiesgt;    lt;prefixgt;[BlazeDS] lt;/prefixgt;    lt;includeDategt;falselt;/includeDategt;    lt;includeTimegt;falselt;/includeTimegt;    lt;includeLevelgt;falselt;/includeLevelgt;    lt;includeCategorygt;falselt;/includeCategorygt;lt;/propertiesgt;lt;filtersgt;    lt;patterngt;Endpoint.*lt;/patterngt;    lt;patterngt;Service.*lt;/patterngt;    lt;patterngt;Configurationlt;/patterngt;lt;/filtersgt;       lt;/targetgt;   lt;/logginggt;      lt;systemgt;       lt;redeploygt;lt;enabledgt;falselt;/enabledgt;       lt;/redeploygt;   lt;/systemgt;

lt;/services-configgt;
The code on the client side is just for testing purposes right now, so pretty basic:Code:
lt;?xml version=quot;1.0quot; encoding=quot;utf-8quot;?gt;
lt;s:Application xmlns:fx=quot;mxml/2009quot;   xmlns:s=quot;library--ns.adobe.com/flex/sparkquot;   xmlns:mx=quot;library--ns.adobe.com/flex/mxquot; minWidth=quot;955quot; minHeight=quot;600quot;gt;
lt;fxeclarationsgt;
lt;s:RemoteObject id=quot;roquot; destination=quot;translationServicequot; endpoint=quot;translation/messagebroker/amfquot; /gt;
lt;/fxeclarationsgt;

lt;s:TextArea text=quot;{ro.test()}quot;/gt;

lt;/s:Applicationgt;
The test() method just returns a string with some text in it.

Oh, and this is what the Debug Flash Player returns as soon as I open the generated swf file:Code:

I'm sure I'm lacking some simple piece of information that would help me pin down your problem.  Can you attach a .zip of your project?

Oh, thanks for that! I didn't do any Flex programming in a while - looks like I need to get back into the topic again

I'm sure you're right. It seems to me like I'm almost there, but some little piece might be wrong or missing, but I just don't see it. However, I don't really want to post my whole project publicly here in the forum, and it's bigger than the allowed file size anyway. Is there another way to get it over to you? I can easily upload it to my server and drop you a link if that helps.

Thanks for all your help so far, I really appreciate that!
