convert from struts to spring3

When I convert from struts to spring, can I still use *.do instead *.htm in web.xml file?

<servlet-mapping>
<servlet-name>spring_mvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

You can use what ever the extension that is appropriate for your application

Servlet Container inteprets the following line as : All the requests with this extension will be handled by servlet with name spring_mvc servlet

<servlet-name>spring_mvc</servlet-name>
<url-pattern>*.do</url-pattern>

I am guessing you are mapping spring_mvs to (DispatcherServlet, which acts as FrontController and a Dispatcher)

Thank you for your info. But when I have the following code:

@Controller
public class Yp_search extends ActionBase_pub
{
static Log log = LogFactory.getLog("mcores.Yp_search");

@RequestMapping(value = {"/yp_search.do}, method = RequestMethod.GET)
protected ModelAndView yp_search(ModelAndView mv,
HttpServletRequest request) throws Exception
{
AppForm theForm = new AppForm();
mv.getModel().put("appForm", theForm);
mv.setViewName("yp_search");
HttpSession session = request.getSession();

try
{
...
} catch (Exception e)
{
...
}

log.debug("view_Yp_search-OK");
return mv;
}
}

and I tried: http://localhost:8080/yp_search.do and I got the following errors:
javax.servlet.ServletException: Could not resolve view with name 'yp_search'
in servlet with name 'spring_mvc'

Same code worked with *.htm
