spring 3 and dwr 3 not working with single configuration file - configuration

Question

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
Shams

Answer 1

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
