Question

I need to create a mule service that will POST data to a web service that expects name/value pairs (not xml), then process the XML response from that service. I cannot find a good example on how to prep the payload for an http POST.

Can someone provide some insight or examples?

What I have so far is (I don’t know if ‘PathToTransformerClass’ is needed):

    <service name="myService">
        <inbound>
            <vm:inbound-endpoint path="myService.request" synchronous="true">
                <custom-transformer class="PathToTransformerClass" />
            </vm:inbound-endpoint>
        </inbound>
        <outbound>
            <pass-through-router>
                <http:outbound-endpoint address="URIofWebServiceToPostTo" method="POST" synchronous="true">
                    <response-transformers>
                        <custom-transformer class="PathToClassToProcessTheResponse" />
                    </response-transformers>
                </http:outbound-endpoint>
            </pass-through-router>
        </outbound>
    </service>

The following might be helpful: http://comments.gmane.org/gmane.comp.java.mule.user/29342

I can’t find any examples either, but it looks like the built-in HTTP transformers are

http-response-to-object-transformer A
transformer that converts an HTTP
response to a Mule Message. The
payload may be a String, stream, or
byte array.

http-response-to-string-transformer
Converts an HTTP response payload
into a string. The headers of the
response will be preserved on the
message.

object-to-http-request-transformer
This transformer will create a valid
HTTP request using the current message
and any HTTP headers set on the
current message.

message-to-http-response-transformer
This transformer will create a valid
HTTP response using the current
message and any HTTP headers set on
the current message.

object-to-http-request-transformer might be your best bet; perhaps you can create a map of key-value pairs and then convert that into URL encoded form? Not sure but hopefully this gives you some things to Google.
