> What's in @Path of ApiResourceImpl?
Thanks. I think I figured it out I was missing "/" at the end. Thanks.
But now I am getting, NullPayload even though I have data in.xml when using curl

2) Component adds some more info as noted on the mule site:
public Object onCall(MuleEventContext muleEventContext) throws Exception {
String payload;
MuleMessage message = muleEventContext.getMessage();
ContainerResponse cr = (ContainerResponse)
message.getInvocationProperty("jersey_response");
String restMethod = cr.getContainerRequest().getMethod();
message.setOutboundProperty("restMethod", restMethod);
payload = (String) cr.getResponse().getEntity();
return payload;
}
3) Is supposed to do the JAXB parsing
public CreateResponse handle(CreateRequest req) {
CreateResponse resp = dh.handle(req);
return resp;

- com.intuit.cg.services.dp.pipeline.api.ApiResourceImpl that is a JAX-RS resource, correctly declared as a Jersey resource so Mule can route messages to it,
- com.intuit.cg.services.dp.pipeline.api.JerseyAdapter that looks like JAX-RS resource but is *not* declared as a Jersey resource! Moreover, being placed downstream in the flow it will consume result messages from com.intuit.cg.services.dp.pipeline.api.ApiResourceImpl: is it really what you want?
- then com.intuit.cg.services.dp.pipeline.api.XmlToApiMessage that extracts a String property from the inflight Mule message,

Those components are hooks for some xml manipulation as on the wire
content. But that shouldn't cause this issue since it's mostly passing
through the Message for now.
Are we missing something here or something wrong that's causing this
issue? From the below error it looks like it's some mimetype issue. I
can try and print message and see what I get.

this is the link that says we need to modify jersey to add
"jersey_response" before forwarding the request.
