+1  Q: 

Create pass through with Mule ESB 2.2.1

I'm attempting to set up a config file for Mule ESB 2.2.1 that routes incoming requests to another box. This seems straight forward, but I am getting connection refused exceptions and I'm not sure why.

Here is the model from my Mule configuration file:

<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>

I am browsing to http://localhost:8787/my-site in my browser, thinking that it will route to http://server2.xyz.com:8080/my-site, but I get a connection refused error.

Here is the console output from the Mule server:

My project wasn't cleaning correctly in Eclipse. Once I ran the correct configuration file, the example above worked as intended.
