Just for the record, here's the Servlet.init() method I use to have
Spring dependency injection in servlets declared in web.xml. Works like
a charm!

    public void init(ServletConfig servletConfig) throws ServletException {
        // Get the application context,
        ApplicationContext ctx = (ApplicationContext)

        // Create an autowire-capable factory
        DefaultListableBeanFactory factory = new

AutowireCapableBeanFactory.AUTOWIRE_BY_NAME, true);
