Answer 1

After adding the "messageSource" bean, I had problems to get the Error Message work with the CookieLocaleResolver because the DispatcherServlet (which does use this for your application automatically) is invoked after the Security. See: http://static.springsource.org/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#localization

My Solution was a custom Filter which sets the LocalContextHolder:

public class LocaleContextFilter extends OncePerRequestFilter {
    private LocaleResolver localeResolver;
    public void setLocaleResolver(LocaleResolver localeResolver) {
        this.localeResolver = localeResolver;
    }
    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
            FilterChain filterChain) throws ServletException, IOException {
        // store Local into ThreadLocale
        if (this.localeResolver != null) {
            final Locale locale = this.localeResolver.resolveLocale(request);
            LocaleContextHolder.setLocale(locale);
        }
        try {
            filterChain.doFilter(request, response);
        } finally {
            LocaleContextHolder.resetLocaleContext();
        }
    }
}

And the Spring Security Context configuration:

  
    
    .....
  
  
    
  

I hope this helps others which has this problem.
