[mule-user] How to Building RESTful HTTP Applications with Mule

[Wang Wayne]

Hi All,

I tried to deploy RESTful webservice in Mule, but it's not work. I'm sure there was a fault in my configuration when integrated with Mule.
My configuration as following:

   
    <model name="Symbio-Rest">
        <service name="HTTPPostSample">
            <inbound>
                <!-- Incoming HTTP requests -->
                <inbound-endpoint address="http://localhost:8000/test" synchronous="true">
                </inbound-endpoint>
            </inbound>
            <http:rest-service-component
                    serviceUrl="http://localhost:8000/sso/webservice/policyservice/test"
                    httpMethod="POST">
            </http:rest-service-component>
        </service>
    </model>
.
Would you tell me how to deploy or give me some documentations about Building RESTful HTTP Applications with Mule.
I really appreicate!

Thanks,
Best Wishes for you!

Hi Andrew,
The Mule configure as following:
<service name="SSOPolicyAuthority">
            <inbound>
                <http:inbound-endpoint address="http://localhost:8001/webservice/policyservice/authority" synchronous="true"/>
            </inbound>
            <http:rest-service-component
                    serviceUrl="http://localhost:8000/sso/webservice/policyservice/authority"

                    httpMethod="POST">
            </http:rest-service-component>
        </service>

Mule console response:

By the way, I checked the whole process, The Mule did not deliver the request body which I send to Mule to RESTful service.
