spring 3 and dwr 3 not working with single configuration file

I am using Spring 3.0 and DWR 3 in my web app. I have some configuration problem. When i use single configuration file for both tech, then the one which i write at top will work and next will not work. And when i made two different DispatcherServlet then they are working fine.

Here is my web.xml configuration:

<servlet>
        <servlet-name>abc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>abc</servlet-name>
        <url-pattern>*.form</url-pattern>
    </servlet-mapping>

    <servlet>
        <servlet-name>abc-dwr</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>abc-dwr</servlet-name>
        <url-pattern>/dwr/*</url-pattern>
    </servlet-mapping>

Here is my abc-servlet.xml file (which contain only Spring configuration):

Here two file, abc-servlet.xml contain Spring configuration and abc-dwr-servlet.xml contain DWR and Spring configuration. I have written Spring configuration in both file, coz if i will remove it from 2nd file Spring will not work. I have tried too much to merge both technology in same configuration file. But only one which i write at top is working and another one is not working. Is there any way to merge both of them in same file, or i am doing some silly mistake? please help me.

Thanks

I was able to make the proper configuration (Spring 3.x + DWR 3 + Tiles) with only one Dispatcher Servlet declared and able to inject Spring services in my DWR controller using annotations:

That very good blog contains lot of useful resources about how to config Spring with many other technos:

Spring + DWR
