Claus Ibsen commented on CAMEL-5723:
------------------------------------
You can use the data format component and use a "dynamic to". But yeah maybe
also nicer to improve jaxb dataformat to support a header to control the
behavior.
> camel-jaxb: partClass and partNamespace dynamically set by header

> Key: CAMEL-5723
> URL: https://issues.apache.org/jira/browse/CAMEL-5723
> Project: Camel
> Issue Type: New Feature
> Components: camel-jaxb
> Reporter: Raúl Kripalani
> Fix For: Future
>
>
> The Camel JAXB Data Format allows to specify a partClass and partNamespace on
> the data format configuration.
> If you have many cases of partial marshalling or unmarshalling, you're forced
> to configure as many data formats as part classes you'll ever need to handle.
> Aside from being inconvenient, it makes route initialisation pretty
> inefficient because a JAXBContext is created per data format, performing a
> full scan and reflection of the package each time. Slows down route startup
> considerably.
> Enhance the Camel JAXB Data Format so that it's capable of doing partial
> unmarshalling at runtime based on message headers.
