The spring security example uses two different spring contexts.
The first is pulled up using the spring ContextLoaderListener. It is used to hook spring security into a filter.
The second is pulled up by the CamelHttpTransportServlet. There is the main configuration includeing the camel context.
I think this is quite ugly and makes things more complicated than they need to be. Especially if you also need the camel context outside the camel servlet.
So I propose to change the code of the Camel Servlet component to simply use the spring context from the ContextLoaderListener. I can try to do the change myself but would be happy for any comments why this was designed so and where I have to be careful.
