I found the error, It was not with the JaxbDataFormat, I had an error in the Converter class (only the class was annotated with @Converter not the method).
I got fooled by the error message informing me that there was an error in unmarshalling. After adding the @Converter to the method name, the code works fine. // Mikael -- View this message in context: http://camel.465427.n5.nabble.com/2-JaxbDataFormat-in-the-same-route-doesnt-work-tp5736799p5736830.html Sent from the Camel - Users mailing list archive at Nabble.com.
