HTTP status 404-Page not found. SpringMVC error - maven

Question

It is my first application in SpringMVC using Maven.
here is the application structure.
Controller code:
When I click on the link in the index.jsp the page should be traversed to helloworld.jsp
index.jsp has this link:
<h3>
Click Here
</h3>
helloworld.jsp
<h2>
${message} ${name}
</h2>
The code for dispatcher servlet:
Update: web.xml file.
I understand that it's a silly question, but as a newbie to SpringMVC structure, I am not able to find the error. Please help!
Spring is starting up.
This is the homepage, when I click on the link, it should be traversed to helloworld.jsp.
And this is the pom.xml.

In the logs you should see something like:
19:05:56,530 INFO [io.undertow.servlet] (ServerService Thread Pool -- 106) Initializing Spring FrameworkServlet 'mvc-dispatcher'
19:05:56,531 INFO [org.springframework.web.servlet.DispatcherServlet] (ServerService Thread Pool -- 106) FrameworkServlet 'mvc-dispatcher': initialization started
19:05:56,547 INFO [org.springframework.web.context.support.XmlWebApplicationContext] (ServerService Thread Pool -- 106) Refreshing WebApplicationContext for namespace 'mvc-dispatcher-servlet': startup date [Fri Mar 31 19:05:56 UTC 2017]; root of context hierarchy
19:05:56,584 INFO [org.springframework.beans.factory.xml.XmlBeanDefinitionReader] (ServerService Thread Pool -- 106) Loading XML bean definitions from ServletContext resource [/WEB-INF/mvc-dispatcher-servlet.xml]
19:05:56,741 INFO [org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor] (ServerService Thread Pool -- 106) JSR-330 'javax.inject.Inject' annotation found and supported for autowiring
19:05:56,859 INFO [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping] (ServerService Thread Pool -- 106) Mapped "{[/hello],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto protected org.springframework.web.servlet.ModelAndView com.crramirez.HelloWorldController.showMessage(java.lang.String) throws java.lang.Exception
19:05:57,084 INFO [org.springframework.web.servlet.DispatcherServlet] (ServerService Thread Pool -- 106) FrameworkServlet 'mvc-dispatcher': initialization completed in 553 ms
Delete these lines in web.xml:
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
and rename the file in WEB-INF from dispatcher-servlet.xml to mvc-dispatcher-servlet.xml
With this your program should work.
