Spring Mobile inside AuthenticationFailureHandler not found - spring

Question

I am development success and failure handlers in Spring Security.
Depends device type I must show one html view or send one json response. To this purpose I use Spring Mobile, but when I create Device object with HtttpServletRequest not found. Some idea?
web.xml
<filter>
<filter-name>deviceResolverRequestFilter</filter-name>
<filter-class>org.springframework.mobile.device.DeviceResolverRequestFilter</filter-class>
</filter>
ApplicationContext.xml
<mvc:annotation-driven>
<mvc:argument-resolvers>
<bean class="org.springframework.mobile.device.DeviceWebArgumentResolver" />
</mvc:argument-resolvers>
</mvc:annotation-driven>
Class
public class AuthFailureHandler implements AuthenticationFailureHandler{
#Override
public void onAuthenticationFailure(HttpServletRequest request, HttpServletResponse response, AuthenticationException ae) throws IOException, ServletException {
Device device = DeviceUtils.getCurrentDevice(request);
if(device.isNormal()){
response.sendRedirect(response.encodeRedirectURL("./userNoAuth"));
} else {
response.sendRedirect(response.encodeRedirectURL("./rest/userNoAuth"));
}
}
}
Error
java.lang.NullPointerException at com.myapp.security.handler.AuthFailureHandler.onAuthenticationFailure(AuthFailureHandler.java:19)
UPDATE:
I am change .getCurrentDevice(HttpServletRequest) method to getRequiredCurrentDevice(HttpServletRequest).
Now I get this error.
java.lang.IllegalStateException: No currenet device is set in this request and one is required - have you configured a DeviceResolvingHandlerInterceptor?

Verify your web.xml contains a filter-mapping for the deviceResolverRequestFilter. The following is a working example from the Spring Mobile Samples repository. Hope that helps!
