Bingo! :)

Doing this by hand, you need to make sure you inject the context into
the RouteBuilder.
You could instead do...
container.addRoutes(builder);
which will probably fix your issue.
Note that if you are using a spring.xml file you can just use the
CamelContextFactoryBean directly then when you look up your
CamelContext it will have all the routes configured...

BTW here's an example using the spring 2 namespaces approach to
configuring a CamelContext along with some routes
