Subject Re: Help with Camel JAXB (SMX4 + Camel 2.1.0)
Date Tue, 23 Feb 2010 08:07:13 GMT

The unmarshal("jxb") refers to a JaxbDataFormat defined in Spring
configuration :
<camelContext>
<routeBuilder ref="myBuilder"/>
<dataFormats>
  <jaxb id="jxb" context="eu.diva.tis.api.domain.esb"/>
</dataFormats>
</camelContext>

And I've triple-checked that the context is correct and no other package
than the one being referenced is used. Note also that this DataFormat is
used with success during the unmarshalling operation :-( ???

I really don't have a clue why the createMethod cannot be found during
marshalling operations, but can be found during unmarshalling. Maybe I'm
using the wrong JAXB library ? But I'm using the standard set provided with
Fuse ESB 4.1 release candidate, so it should be OK ?
