Hi Sorry yeah its a string as this was how its done in Camel 1.x
We could change it to a real ProtocolCodecFactory object instead of String and then it should work For uri you should use the # notation to lookup the codec. Btw the NPE you get is because you create it like that using Spring style and the endpoint does not have the CamelContext associated. And thus it can not got hold of the registry to lookup the codec. I will fix it. On Thu, Mar 5, 2009 at 10:11 AM, Nicolas Bouillon <nico...@bouil.org> wrote: > I've already tried that.
