Domanda

Sto tentando di creare un file di configurazione per il Mule ESB 2.2.1 che indirizza le richieste in arrivo a un altro box. Questo sembra semplice, ma io sono sempre connessione rifiutata eccezioni e non sono sicuro perché.

Ecco il modello dal mio file di configurazione Mulo: 

<model name="ProxySample">
    <service name="HttpProxyService">
        <inbound>
            <http:inbound-endpoint address="http://localhost:8787" synchronous="true"/>
        </inbound>
        <outbound>
            <pass-through-router>
                <outbound-endpoint address="http://server2.xyz.com:8080#[header:http.request]" synchronous="true"/>
            </pass-through-router>
        </outbound>
    </service>
</model>

Sto navigando a http: // localhost: 8787 / my-sito nel mio browser, pensando che lo farà rotta verso http://server2.xyz.com:8080/my-site , ma ottengo un errore di connessione rifiutata.

Ecco l'output della console dal server Mulo:

È stato utile?

Soluzione

Il mio progetto non stava pulendo correttamente in Eclipse. Una volta che ho eseguito il file di configurazione corretta, l'esempio precedente ha funzionato come previsto.

Altri suggerimenti

che dovrebbe funzionare definitelly, se si wan't per rendere il servizio più leggibile, è possibile anche scrivere il componente implicita: 

<model name="ProxySample">
    <service name="HttpProxyService">
        <inbound>
            <http:inbound-endpoint address="http://localhost:8787" synchronous="true"/>
        </inbound>

        <bridge-component />

        <outbound>
            <pass-through-router>
                <outbound-endpoint address="http://server2.xyz.com:8080#[header:http.request]" synchronous="true"/>
            </pass-through-router>
        </outbound>
    </service>
</model>
