RE: [flexcoders] Problem with RemoteObject Java

The method on your java class appears to be called "doTest", but your MXML method for your RemoteObject is called "createTest"... but that aside, I think something else is wrong with your connectivity because the client can't seem to connect to the channel endpoint.

When you compile your mxml file, did you remember to specify a --services command line switch to point to your services-config.xml file (which is typically in /WEB-INF/flex/services-config.xml)? Also, it appears your remoting service destination is using the "my-amf" channel... can you check this channel definition in services-config.xml and if the endpoint uri attribute has a {context.root} token you'll either need to replace this with the web application context root "/myapp" or specify it on the command line as --context-root=/myapp

Note that if you change services-config.xml or any of the included services files (such as remoting-config.xml) you'll need to restart the server and recompile your mxml. If you're using Flex Builder you may also want to force a recompile by doing a clean first.

Subject: [flexcoders] Problem with RemoteObject Java

Hi, I have an application with flex 2.0, flex data services and java and I want to access methods of my JAVA classes. So I use the remoteObject.

Here is the code :

Test.java

package beans;

public class Test {

    public Test()
    {
        System.out.println("-= Test start =-");
    }

    public String doTest()
    {
        return "-= This is a test =-";
    }

}

remoting-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service"
    class="flex.messaging.services.RemotingService"
    messageTypes="flex.mess! aging.messages.RemotingMessage">

    <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="test">
        <properties>
            <source>beans.Test</source>
            <scope>application</scope>
        </properties>
    </destination>

</service>

index! .mxml

<?xml version="1.0"?>

&l! t;mx:App lication xmlns:mx="http://www.adobe.com/2006/mxml"
    initialize="applicationInit()"
    layout="absolute"
    backgroundGradientColors="[#ffffff, #808080]"
    viewSourceURL="srcview/index.html"
    creationComplete="doTest()">

    <mx:Script>
    <![CDATA[
                     import mx.controls.Alert;
                     import mx.rpc.events.FaultEvent;
                     import mx.collections.ArrayCollection;
    ! ;                 import flash.events.MouseEvent;
                     import mx.rpc.AsyncToken;
                     import mx.data.*;
                     import mx.managers.*;

       !           &n! bsp;&nbs p; [Bindable]

                     private function doTest():void
                     {
                         test.doTest();
                     }

  !             ]]>
       </mx:Script>

<mx:RemoteObject id="test" destination="test">
<mx:method name="createTest"/>
</mx:RemoteObject>

When I launch the server " -= Test start =-" is printed on tomcat so the remoteObject is good initialized but after there is an error due to the method createTest.

Here is the final message when i launch the application :

[RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" faultDetail="Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed"]

Please help me.
