Problema: Flash + Java + Blazeds + eclipse

lucasgcp · Fevereiro 14, 2011, 12:04pm

Bom dia galera do guj!

Meu problema éo seguinte: instalei em minha maquina o eclipse juntamente com um plugin do adobe flash builder. Para realizar a “conexao” entre java e flash estou usando o blazeds. Busquei varios tutoriais na internet que ensinavam como configurar os arquivos para proporcionar a comuçao entre flash e java. Porem, mesmo seguindo passo a passo, nao obtive sucesso. O programa é so um exemplo mesmo, onde o que o cara digitasse no campo “Usuario” seria repedito no campo “Senha”.

Abaixo seguem as modificações indicadas nos arquivos e o erro relatado:

services-config.xml


<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service" 
    class="flex.messaging.services.RemotingService">

    </adapters>

    <default-channels>
        <channel ref="my-amf"/>
    </default-channels>
        
    <destination id="conecta">
    	<properties>
    		<source>ControleUsuario</source>
    	</properties>
    </destination>

</service>

ClasseJava :

public class ControleUsuario {
	
	public String Usuarios(String usuario){
		return "Usuario : " + usuario;
	}

}

Obrigado pela atenção!

falta o caminho no services-config.xml

&lt;channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel"&gt;
            &lt;endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf" class="flex.messaging.endpoints.AMFEndpoint"/&gt;
&lt;/channel-definition&gt;

depois tenta acessar direto do brownser para testar a conexão
ex:

http://localhost:8080/contexto_de_sua_aplicacao/messagebroker/amf

posta seu remoting-config, web.xml etc…

Me esqueci de mencionar…

Digitando http://localhost:8080/Teste/messagebroker/amf no browser, carrega normalmente uma pagina em branco… sem erros…
