Configuring the Jaxb marshaller?

[jamie3_james.archibald]

I have a route that uses the Jaxb marshaller:

String pkg = ObjectFactory.class.getPackage().getName();

          JaxbDataFormat jaxb = new JaxbDataFormat(pkg);

          jaxb.setPrettyPrint(true);

          jaxb.setPartClass(MyClass.class.getName());

          jaxb.setPartNamespace(new QName(

                    "http://mynamespace/namespace","",""));

          jaxb.setEncoding("UTF-8");

from("activemq:someQueue")

.unmarshal(jaxb)

.process( // do something )

.marshal(jaxb)

.to("activemq:anotherQueue");

I want to know how I can configure the marshaller such that it won't output the xml declaration and also namespaces.

Can you google about JAXB as I guess it have some options to control the output. Then we may have to add a way in the Camel JaxbDataFormat to configure those options as well.

The properties are set on the Marshaller as follows:

Marshaller mar = ...

mar.setProperty(..,...)

I am pretty sure (correct me if I am wrong) that camel lazily creates the marshaller, or when the camel route is started, not allowing the developer to access the marshaller before the route is created.

Maybe to support setting JAXB properties (on lazy init) they could be passed via the camel route:

.from("direct:input")

.setHeader(Marshaller.JAXB_FRAGMENT, constant(Boolean.True)) // don't add xml declaration

.marshal(jaxb)

.to("direct:output)

Camel create new marshaller in the marshal method to be thread safe.

I just create a JIRA[1] for this feature.
