Pessoal
Estou fazendo uma simples integração entre Java + Flash Builder 4 + BlazeDS, basicamente o flex vai exibir uma string vinda de uma classe java.
Eis a versão dos meus SWs:
[color=darkblue]eclipse-jee-ganymede-SR2-win32.zip
apache-tomcat-6.0.24.exe
blazeds-bin-3.2.0.3978.zip
flashbuilder4_b2_plugin_win_100509.exe
jdk-6u17-windows-i586.exe[/color]
Segue agora o passo a passo da montagem do meu sistema:
Inicialmente, eu crio um novo projeto Flex
-indico que é uma aplicação J2EE
-indico que usarei o BlazeDS
-seto nome da pasta que vai conter as classes Java
Indico que usarei o Tomcat, deixo o Output folder com o mesmo nome do Context folder -> [color=blue]WebContent[/color]
-Apago a pasta flex_libs e seto o Output Folder URL para: http://localhost:8080/p01/
meu projeto ficou assim:
Agora eu faço meu p01.mxml :
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/halo" minWidth="1024" minHeight="768">
<fx:Declarations>
<s:RemoteObject id="locarSer" destination="servico"/>
</fx:Declarations>
<mx:VBox>
<s:Label text="teste"/>
<s:TextInput id="campo" change="locarSer.ola(campo.text);"/>
<s:Label id="label2" text="{locarSer.ola.lastResult}"/>
</mx:VBox>
</s:Application>minha classe Java OlaMundo.java
package meuPackage;
public class OlaMundo {
public String ola(String nome){
return "vc digitou: "+nome;
}
}
No Web.xml faço a seguinte alteração:
eu alterei:
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>para:
<welcome-file-list>
<welcome-file>p01.html</welcome-file>
</welcome-file-list>no remoting-config.xml eu inclui a tag <destination> setando minha classe java:
<?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="servico">
<properties>
<source>OlaMundo</source>
</properties>
</destination>
</service>Quando eu executo meu projeto (Run on Server) A minha tela aparece normal, mas quando eu insiro um texto no campo , aparece esse erro:
erro 1:
[RPC Fault faultString="[MessagingError message='O destino 'servico' não existe ou não tem canais definidos (e o aplicativo não define nenhum canal padrão).']" faultCode="InvokeFailed" faultDetail="Não foi possível estabelecer conexão com 'servico'"]

Aparentemente, o meu Web.xml não está conseguindo linkar minha classe java com meu <s:RemoteObject id=“locarSer” destination=“servico”/> e o 2º erro RPC Fault faultString=“Falha no envio” … parece que está faltando alguma coisa ainda para fazer a classe se comunicar com o flex:
Alguem pode me dar uma luz do que pode estar faltando??
obrigado
