At the final testing, it is working. My sample pom.xml will be as follow:

And here is the cometd-context.xml:

And some little changes in web.xml to use the spring like my previous project:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:main-context.xml</param-value>
</context-param>
   
    <servlet>
        <servlet-name>cometd</servlet-name>
        <servlet-class>org.cometd.annotation.AnnotationCometdServlet</servlet-class>
        <init-param>
            <param-name>timeout</param-name>
            <param-value>30000</param-value>
        </init-param>

        </init-param>
        <init-param>
            <param-name>maxInterval</param-name>
            <param-value>10000</param-value>

            <param-name>services</param-name>
            <param-value>com.sillycat.easycometd.comed.chat.service.ChatService</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>cometd</servlet-name>
        <url-pattern>/cometd/*</url-pattern>
    </servlet-mapping>
   
    <filter>
        <filter-name>continuation</filter-name>
        <filter-class>org.eclipse.jetty.continuation.ContinuationFilter</filter-class>

    </filter>
    <filter-mapping>
        <filter-name>cross-origin</filter-name>
        <url-pattern>/cometd/*</url-pattern>
    </filter-mapping>
   
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

It is working now. And I will try to refactor this project.
