Tomcat server ran into 404 for unknown reason - spring

Question

I'm trying to use Maven to run on Tomcat 8 as server. I'm newbie to these two, so I have an example file which I haven't made, and is supposed to print 'welcome'.
However, I receive this error
The requested resource is not available.
I checked TomCat log on my IDE (Netbeans) and I found out it gives this errors:
org.apache.catalina.core.ApplicationContext.log Initializing Spring root WebApplicationContext

My problem is that, the line I made it bold says I don't have this repository :org.springframework.web.servlet.DispatcherServlet in my project. However, I'm sure it can be seen in my dependencies.The file spring-webmvc.4.3.8.Release.jar is visible in the expected folder(WEB-INF/lib) and it contains a class file named DispatcherServlet.class which is accessible in my project window in netbeans.
I also checked to POM file, and I have these which declare this file-and two other spring web jar files- as dependencies:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.3.8.RELEASE</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<!-- Set this to the respective version -->
<version>4.3.8.RELEASE</version>
<scope>provided</scope>
<type>jar</type>
</dependency>
So, is there anything I'm doing wrong here? since TomCat doesn't provide any further info to tell exactly what couldn't be found, the only problem I see is this.
Thanks in advance:)

You can check if there are libs in your artefact (war). If pom.xml is configured incorrectly, some libs might absent there.
