Also my web.xml

    </servlet-class>

         </init-param>
   <load-on-startup>1</load-on-startup>
   <async-supported>true</async-supported>
</servlet>

<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
    <async-supported>true</async-supported>
</servlet-mapping>

Any help? Thanks.

EDIT

After changing my pom. This is what I get

We get `NoClassDefFoundError` when **The searched-for class definition existed when the currently executing class was compiled, but the definition can no longer be found.** This means your dependency configurations are fine. Could you please check if the `spring-web.jar` is available in the lib folder of your deployment package(war)? — Mithun, Nov 21 '14 at 06:14

The class can be found in spring-web.jar, since version 4.0.0, see API docs.

Update:

"NoSuchMethodError: javax.servlet.http.HttpServletRequest.isAsyncSupported"

This is a method is available since Servlet 3.x, please check your web.xml header, weather you are using the right version. Check this page too, to see if you are using the right Jetty. Must be 8.x or above.

Thanks for a response, this is what I thought also, but after looking in my jar spring-web is already present. – dup135 Nov 21 '14 at 01:29
