SOAP

I'm using Camel 2.12 and have a standalone Camel instance.

One of the routes is an http endpoint that expects a post body containing a
SOAP envelope that then needs to unmarshall the soap, marshall it into Json
and hand it off to another endpoint that expects Json:

ServiceInterfaceStrategy strategy = new
ServiceInterfaceStrategy(MyService.class, true);
SoapJaxbDataFormat soapDataFormat = new
SoapJaxbDataFormat("com.foo.bar.listings", strategy);

from("jetty:http://0.0.0.0:2018")
.unmarshal(soapDataFormat)
.marshal().json(JsonLibrary.Jackson)
.setHeader(Exchange.CONTENT_TYPE, constant("application/json"))
.setHeader(Exchange.HTTP_METHOD, constant("POST"))
.to("direct:dbUpdate");

Hoewever on startup my Camel does this:

14:40:12.059 [main] INFO o.a.camel.impl.DefaultCamelContext - Apache Camel
2.12.1 (CamelContext: camel-1) uptime 0.618 seconds
