How can I fix Missing WebSocket ServerContainer enabling WebSockets with CometD, Jetty and Spring?

[Diego Gliosca]

I'm experiencing a problem trying to enable WebSockets on CometD. My configuration is the following: 
- CometD 3.0.5 
- Jetty 9.0.6, 
- SpringMVC 3.2.4 

web.xml

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

    <servlet>
        <servlet-name>cometd</servlet-name>
            <servlet-class>org.cometd.server.CometDServlet</servlet-class>
            <async-supported>true</async-supported>
        </servlet>

        <servlet-mapping>
            <servlet-name>cometd</servlet-name>
            <url-pattern>/cometd/*</url-pattern>
        </servlet-mapping>
    </servlet>
    </web-app>

applicationContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.springframework.org/schema/beans
                       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
  <bean id="bayeuxServer" class="org.cometd.server.BayeuxServerImpl" init-method="start" destroy-method="stop">
        <property name="options">
            <map>
                <entry key="javax.servlet.ServletContext" value-ref="servletContext" />
                <entry key="ws.cometdURLMapping" value="/cometd/*" />
                <entry key="logLevel" value="0" />
                <entry key="timeout" value="15000" />
            </map>
        </property>
        <property name="transports">
            <list>
                <bean id="websocketTransport" class="org.cometd.websocket.server.WebSocketTransport">
                    <constructor-arg ref="bayeuxServer" />
                </bean>
            </list>
        </property>
    </bean>
</beans>

The exception that I'm getting is the following:

You probably do not have the right dependencies in your web application.
Please refer to this section for the dependencies:
http://docs.cometd.org/reference/#_java_server_transports

Also, please use CometD archetypes like explained in the StackOverflow answer.
The archetypes will build the right skeleton of the application for
you, and will go straight into development rather than trying to
assemble the application yourself and then stumble into problems.
