spring web-mvc and vaadin co-existing

I have read a bunch of threads here on the forum and have success in having Vaadin working in spring using Spring DispatchServlet to front the request. However, I am having trouble getting both to work at the same time. It comes down to the servlet-mapping in web.xml of org.springframework.web.servlet.DispatcherServlet.

In order to get Vaadin to working, I need the servlet-mapping to Spring’s org.springframework.web.servlet.DispatcherServlet to be “/*”.
But for spring web-mvc to work (setup by SpringRoo 1.1.2,), it needs to be “/”

Have any one had any luck having some url use Vaadin and some url serving regular spring-mvc?

Why pass the requests to the Vaadin application through DispatchServlet instead of directly to the Vaadin ApplicationServlet?

For Vaadin, you should not need to map “/" - you only need both “/VAADIN” and the Vaadin application path (e.g. “/myapp”) to point to the Vaadin ApplicationServlet. If the only application is a Vaadin servlet, "/” is a convenient “shortcut” for these, making the application visible at the root.

If you do the more specific mappings for Vaadin, you could then map other paths (“/*” or some part of it) to the DispatchServlet for Spring MVC.

I am tring to add vaadin to my Spring MVC project. Basically I need to take advantage of both jsp view and vaadin generated viewes.
I need to use jsp for frontend let’s say http://localhost:8080/HelloWorld/ and use vaadin for admin section http://localhost:8080/HelloWorld/admin.

URL: http://localhost:8080/HelloWorld/hello
The Spring Controller is working when I hit this

URL: http://localhost:8080/HelloWorld/admin
BUT vaadin controller give me following error with this

javax.servlet.ServletException: com.vaadin.server.ServiceException: com.vaadin.server.ServiceException: No UIProvider has been added and there is no “UI” init parameter.
