Re: MinaConfiguration codec property
Should I create my Endpoints such they are attached to my CamelContext ? On Thu, Mar 5, 2009 at 10:21, Claus Ibsen claus.ib...@gmail.com wrote: 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.

Re: MinaConfiguration codec property
Hi Since the myMinaEndpoint is created by the myMinaFactory which has not the reference from the application context which can be referred by the camelContext . So the myMinaEndpoint can't get find the instance of myCodec. My suggestion is adding a constructor-arg of the camel context under the bean id=myMinaFactory ... to let the myMinaFactory hold the reference of camelContext.
