Spring & DWR. General questions

[ctapobep]

I had SpringMVC application. And now I want to add AJAX-functionality. As far as I know, DWR - is one of the best ways to do this.
I added this into web.xml:

    <servlet>
        <servlet-name>dwr</servlet-name>
        <servlet-class>org.directwebremoting.spring.DwrSpringServlet</servlet-class>
        <init-param>
            <param-name>debug</param-name>
            <param-value>true</param-value>
        </init-param>
    </servlet>
<servlet-mapping>
        <servlet-name>dwr</servlet-name>
        <url-pattern>*.dwr</url-pattern>
    </servlet-mapping>

Then I created a new applicationContext-dwr.xml and put it into contextConfigLocation in web.xml.
Is it right what I am doing? Will ServletDispetcher and dwr-configuration(actually it's a dispetcher too) work simultaneously without making any demage to each other?
