Stan Lewis updated CAMEL-1850:
------------------------------

    Attachment: patch.txt

I looked into implementing this in camel-spring's ResourceBasedEndpoint but it felt like the solution was starting to get really complicated as that endpoint is designed to only manage one resource.  This way is definitely a lot simpler and I think is a good approach to implementing this feature.

> It would be nice to have a message header that can be used to specify which velocity template to be used for the message. This allows to dynamically use different templates while still preserving velocity endpoint cache. In real life you will have more than 1 template and you use of template will change from message to message.
> Something like -
> 	
> from("direct:start")
> .setHeader("velocityTemplate", "orderDisplay.vm"); 
> .to("velocity:dummyTemplate.vm") 
> Currently to achieve this you have to define custom bean or some processor.
