I only described the overall approach by providing a crude servlet that queried the Spring context to get the Application instance. At the time of Learning Vaadin 7, I was eager to work on add-ons the community provided in terms of Spring integration.

What is missing, however, is how to use method injection with my new preferred method for configuration, Java Config. My start point is the following, using both autowiring (shudder) and method injection.
