Answer 1

Your bean definition

<bean p:viewClass="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/WEB-INF/pages/"
      p:suffix=".jsp"/>

doesn't declare a class attribute which is mandatory in this case. It should be

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:viewClass="some view class"
      p:prefix="/WEB-INF/pages/"
      p:suffix=".jsp"/>

The p:viewClass attribute is referring to the property named viewClass in the InternalResourceViewResolver class. Obviously, set an appropriate value, maybe org.springframework.web.servlet.view.JstlView or org.springframework.web.servlet.view.InternalResourceView .

This and more are explained in the official documentation .
