spring mvc InternalResourceViewResolver doesnt get prefix

spring mvc InternalResourceViewResolver doesnt get prefix but suffix from controller.

<context:component-scan base-package="pizzaorder" />

<mvc:annotation-driven />

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix">
        <value>/WEB-INF/</value>
    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>

controller:

package pizzaorder;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.portlet.ModelAndView;

@Controller
public class PizzaController {

@RequestMapping("/")
public ModelAndView getAlap(){

    ModelAndView model1=new ModelAndView("index");

    return model1;
}

}

if I modify suffix to index.jsp, it works well. if left suffix .jsp it shows:

also in debug I see that view name is correctly passed:

Ok, got the issue ! You have the wrong import for ModelAndView class in your controller. It should be

import org.springframework.web.servlet.ModelAndView;

and not

import org.springframework.web.portlet.ModelAndView;

Change this and your application would work like a charm !.
