Pre/PostAuthorize annotations not working - spring

Question

As it seems that Spring Security forum is not giving much support, I'm forced to ask the same question here as well. I'm building a web application using Spring 3.0.6 and Spring Security 3.0.7, but there's a problem that's driving me insane. Method protection annotations just don't work. I'm protecting the method on my service interface this way:
public interface AlbumGenreService {
#PreAuthorize("hasRole('ROLE_ADMIN')")
public void deleteGenre(Integer genreId);
}
and then invoking the method in the controller:
#RequestMapping(value="/genres/delete/{genreId}")
public String deleteGenre(#PathVariable("genreId") Integer genreId, Model model) {
albumGenreService.deleteGenre(genreId);
return "redirect:/genres/view";
}
When I log in with ROLE_USER role and try to delete the genre, the access to the protected method is granted and the genre is deleted.
My configuration is as follows:
web.xml
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherSe rvlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>

Hope you could help me to figure out what's going wrong. Thanks.
