Destination does not exist (help please)

Question

Background:
- Using Flex Builder 3 plugin for Eclipse
- Downloaded latest BlazeDS release build
- Running Tomcat 6.0.16
=======
First I want to note the samples that come with BlazeDS run
absolutely fine.
So I created a new project in Flex Builder 3. I'm just trying
to get something simple working at first so my one mxml file is as
follows (I stripped out everything except the code in question):
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:RemoteObject id="ro"
destination="enrollmentService"/>
<mx:DataGrid
dataProvider="{ro.getEnrollmentList.lastResult}" width="100%"
height="100%"/>
<mx:Button label="Get Data"
click="ro.getEnrollmentList()"/>
</mx:Application>
=====
I created and EnrollmentService class and I'm sure it's
getting compiled to WEB-INF/class...I see .class file there.
I added the flex folder to the WEB-INF folder. My
remoting-config.xml is as follows (because of problems I specified
a default and repeated it to be sure):
<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service"
class="flex.messaging.services.RemotingService">
<adapters>
<adapter-definition id="java-object"
class="flex.messaging.services.remoting.adapters.JavaAdapter"
default="true"/>
</adapters>
<default-channels>
<channel ref="my-amf"/>
</default-channels>
<destination id="enrollmentService">
<properties>
<source>test.service.EnrollmentService</source>
</properties>
<channels>
<channel ref="my-amf"/>
</channels>
</destination>
</service>
My services-config has the following channel defined:
<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>
My web.xml is a follows:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD
Web Application 2.3//EN" "
http://java.sun.com/dtd/web-app_2_3.dtd">

So I start Tomcat from Eclipse and run the app by clicking
the Run button in Eclipse. The app comes up fine, but when I press
the "Get Data" button. I get the error message below. For the life
of me I don't understand why. I clearly have a default channel AND
I have specified a channel. This is so frustrating...any help would
be greatly appreciate.

Answer 1

While creating a Flex project using Flex builder, did you
select the server type for your project? If you did not select a
server type for your flex project, did you configure your compiler
to include your services-config.xml using the -services argument?
In your project's compiler settings, add -services
"configurationfiles/services-config.xml" argument to the compiler
arguments. The path should point to your services-config.xml.
If the above mentioned steps were completed and still your
facing problem, can you please try running "clean" on your project.
Hope this helps.
