Validator nullpointerexception

I am using this tutorial for enabling annotation based validation using spring bean validation framework. I am using spring modules 0.9 and spring 2.5.6

I get NullPointerException when I hit the submit button

//--

java.lang.NullPointerException springmvc.web.CarNewController.onSubmit(CarNewCont roller.java:139) sun.reflect.NativeMethodAccessorImpl.invoke0(Nativ e Method) sun.reflect.NativeMethodAccessorImpl.invoke(Native MethodAccessorImpl.java:39) sun.reflect.DelegatingMethodAccessorImpl.invoke(De legatingMethodAccessorImpl.java:25) java.lang.reflect.Method.invoke(Method.java:597) org.springframework.web.bind.annotation.support.Ha ndlerMethodInvoker.doInvokeMethod(HandlerMethodInv oker.java:421) org.springframework.web.bind.annotation.support.Ha ndlerMethodInvoker.invokeHandlerMethod(HandlerMeth odInvoker.java:136) org.springframework.web.servlet.mvc.annotation.Ann otationMethodHandlerAdapter.invokeHandlerMethod(An notationMethodHandlerAdapter.java:326) org.springframework.web.servlet.mvc.annotation.Ann otationMethodHandlerAdapter.handle(AnnotationMetho dHandlerAdapter.java:313) org.springframework.web.servlet.DispatcherServlet. doDispatch(DispatcherServlet.java:875) org.springframework.web.servlet.DispatcherServlet. doService(DispatcherServlet.java:807) org.springframework.web.servlet.FrameworkServlet.p rocessRequest(FrameworkServlet.java:571) org.springframework.web.servlet.FrameworkServlet.d oPost(FrameworkServlet.java:511) javax.servlet.http.HttpServlet.service(HttpServlet .java:637) javax.servlet.http.HttpServlet.service(HttpServlet .java:717) --//

This is how I use it in Controller

//--

@Autowired(required=true)
// @Qualifier("beanValidator") private Validator validator;

public void setValidator(Validator validator) {
this.validator = validator;
}

--///

And this is the code in applicationcontext.xml
class="org.springmodules.validation.bean.conf.load er.annotation.AnnotationBeanValidationConfiguratio nLoader"/>

<bean id="validator" class="org.springmodules.validation.bean.BeanValid ator"
p:configurationLoader-ref="configurationLoader"/>


<!-- Load messages -->
<bean id="messageSource"
class="org.springframework.context.support.Resourc eBundleMessageSource"
p:basenames="errors"/>

--//

Applicationcontext.xml is loaded fine. I get the error when I hit submit.

//---

@RequestMapping(method=RequestMethod.POST) public ModelAndView onSubmit(@ModelAttribute("car")Car car,BindingResult bindingResult,HttpSession session) throws ServletException {

if(bindingResult == null)
logger.info("bindingResult is null");
if(car == null)
logger.info("Car is null");

if(validator == null)
logger.info("validator is null");
validator.validate(car, bindingResult);

--//

"validator is null" is printed out..

I am using Springmodules 0.9. Thanks for your quick help guys.
