Hi people!
I’m having problems integrating spring with Vaadin following the wiki IV - Configuring and Using Vaadin Spring without Spring Boot and I can’t get it to work. The error I recieve is:
INFO: No Spring WebApplicationInitializer types detected on classpath

My UI looks like this
@Theme("mytheme")
@SuppressWarnings("serial")
@SpringUI
public class MyVaadinUI extends UI implements LoginListener
{
@WebListener
public class MyListener extends ContextLoaderListener {
}
@Configuration
@EnableVaadin
public static class MyConfiguration {
}
@Autowired
private SpringViewProvider prov;
@WebServlet(value = "/*", asyncSupported = true)
public static class Servlet extends SpringVaadinServlet {
}
@Override
protected void init(VaadinRequest request) {...}

Thanks in advance.
