Spring MVC URI template problem

In Spring MVC 3 on Tomcat 6, I can't seem to get RequestMappings of the form /x/y/z to work. /x/y seems to work fine and that's what all the example in docs show.

For example, why does this work

@RequestMapping(value="/browse/{categoryName}");

but this is doesn't work:

@RequestMapping(value="/browse/category/{categoryName}");

Browsing to http://localhost:8080/myapp/browse/category/books generates a HTTP 404 from Tomcat. The method looks like this:

@Controller
public class BrowseController {
    @RequestMapping(value = "/browse/category/{categoryName}", method = RequestMethod.GET)
    public String showCategory(@PathVariable("categoryName") String categoryName, Model model) {
        model.addAttribute("categoryName", categoryName);
        return "Browse";
    }
}

I see this message in the Tomcat output window in Netbeans 6.9:

Nov 14, 2010 2:02:03 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/myapp/browse/category/model] in DispatcherServlet with name 'dispatcher'

EDIT: added more tracing info from the log. Please disregard the timestamps since this questions was edited over two days.

Upon deploying the app:

Nov 15, 2010 9:33:29 PM org.springframework.web.servlet.FrameworkServlet initServletBean
INFO: FrameworkServlet 'dispatcher': initialization completed in 501 ms

When I made the call to http://localhost:8080/myapp/browse/category/model,

Nov 15, 2010 9:34:28 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/myapp/browse/category/model] in DispatcherServlet with name 'dispatcher'

And here's my web.xml dispatcher config:

<servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

So is there any reason why I URI pattern works but the other doesn't?

You may want to add a request mapping for the browse controller. Try this

@Controller
@RequestMapping("/browse")
public class BrowseController
{
    @RequestMapping(value = "/category/{categoryName}", method = RequestMethod.GET)
    public String showCategory(@PathVariable("categoryName") String categoryName, Model model)
    { 
        model.addAttribute("categoryName", categoryName);
        return "Browse";
    }
}

Your URL pattern should be /* in the servlet mapping.
