Trying to deploy Spring app to Tomcat

I`m truing to make a simple Spring web application. I make the war file with mvn package. When e deploy the file to the Tomcat it gives me an exception that i can not fix. I will copy all my code here. I hope that someone will help me to fix my project.

HelloController.java

    package com.nikola.hellocontroller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;



import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;


public class HelloController extends AbstractController {

    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest arg0, HttpServletResponse arg1)
            throws Exception {
        ModelAndView modelandview = new ModelAndView("HelloPage");
        modelandview.addObject("welcomeMessage", "Good Day.");

        return modelandview;
    }
}

I think in spring-dispatcher-servlet.xml the Bean configuration is wrong. The package for that class is wrong. Use this:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <bean id="HandlerMappping"
          class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" />

    <bean name="/welcome.html" class="com.nikola.hellocontroller.HelloController" />


    <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>
</beans>

That should solve the ClassNotFoundException

In addition I would add a provided dependency to pom.xml to have the HttpServletRequest around:

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>
        <scope>provided</scope>
    </dependency>

try removing 4.1.1 for spring-websocket as well. i think there might be a version conflict.

or run mvn clean package and take a look at the WEB-INF/lib in the target directory you should see spring-webmvc-4.1.1.jar
