Rest DSL IN/OUT types
Hello!
I've had some problems trying the new rest dsl from camel and I'd like to
know if there is a way to do this:
restConfiguration()
.component("netty-http")
.host("0.0.0.0")
.bindingMode(*RestBindingMode.auto*)
.port("{{server.port}}");
rest("/mail")
.post("/send")
.consumes("text/xml")
.produces("text/xml")
.type(A.class)
.to("direct:msg");
Until here I received a A.class from the clients with no problem.
But from "direct:msg" I'd like to return a (xml) String to the client. Like
this:
from("direct:msg").routeId("direct:msg")
.log("message received: ${body}")
.setBody(new ConstantExpression("<?xml version=\"1.0\"
encoding=\"UTF-8\"?><ok>ok</ok>"));
And than, error:
java.io.IOException: javax.xml.bind.MarshalException
- with linked exception:
[com.sun.istack.SAXException2: unable to marshal type "java.lang.String" as
an element because it is missing an @XmlRootElement annotation]
Look obvious, but I'd like to know if there a way to do this.
Thanks!

Re: Rest DSL IN/OUT types
Posted by Claus Ibsen <cl...@gmail.com>.
Hi
Yeah found it outs really camel-jaxb that should support this.
So to support your use case in 2.14.1, you set the
mustBeJAXBElement=false which you can configure on the rest data
format property.
For example
restConfiguration().component("restlet").host("localhost").port(portNum).bindingMode(RestBindingMode.auto)
// turn off must be JAXB as we create the
output type ourselves as xml in a String type
.dataFormatProperty("mustBeJAXBElement", "false");

Hi
Yeah sounds good.
Its this guy
org.apache.camel.processor.binding.RestBindingProcessor
which we need to enhance to allow the RestBindingMarshalOnCompletion
part not to do a jaxb in those situations

It'll be nice. Imagine could use a template engine to create some returns and mix this with some bindings.
I will look the src and if I could help I can try.

Re: Rest DSL IN/OUT types
Posted by Claus Ibsen <cl...@gmail.com>.
Hi
Ah yeah as it marshalled using JAXB for IN it defaults to do the
reverse on out. But as you have auto mode, we could likely detect that
if the message body does not have @Jaxb annotations it should use it
as-is. Also we could detect if the body is a String and use that
as-is, as its assume xml content to be returned as-is.
