ClassNotFoundException for DispatcherServlet

since a day I have a very annoying problem - I can't run any Spring MVC application :/ Today I have tried to write something basing at Spring Documentation. So i created this from scratch:

web.xml

<web-app>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/root-context.xml</param-value>
  </context-param>
  <servlet>
    <servlet-name>bloger</servlet-name>
    <servlet-class>org.spring.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value></param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>bloger</servlet-name>
    <url-pattern>/bloger/*</url-pattern>
  </servlet-mapping>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>

root-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://ift.tt/GArMu6"
    xmlns:xsi="http://ift.tt/ra1lAU"
    xmlns:p="http://ift.tt/1jdM0fE"
    xmlns:context="http://ift.tt/GArMu7"
    xsi:schemaLocation="
    http://ift.tt/GArMu6
    http://ift.tt/1jdM0fG
    http://ift.tt/GArMu7
    http://ift.tt/1jdLYo7">

    <context:component-scan base-package="spring.blog.test"/>

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

simplecontroller:

@Controller
public class SimpleController {
    @RequestMapping("/hello")
        public String helloWorld() {
        return "index";
    }
}

and of course pom.xml

I am running it with Spring Tool Suite( 3.6.0.RELEASE at windows) - I had similar problems with other projects from developers' blogs. Maybe You have simple Spring MVC template that HAVE TO works ?

P.S it doesn't work with spring v. 3
