Spring MVC application don't work with Tomcat and Eclipse

Question

I'm having a lot of trouble trying to use Spring Framework and a don't know where is the error. I'm deploying the application using Tomcat 7.0.68.

When I try to use the URL (http://localhost:8080/fj21-spring/olaMundo) I'm getting a 404 error, but its should be mapped to call my Action method on my Controller class, as below:

package com.caelum.tarefas.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class TarefasController {

  @RequestMapping("/olaMundo")
  public String execute(){
      return "ok";
  }
}

My pom.xml file is what follows:

  <property name="suffix" value=".jsp" />
 </bean>
</beans>

I expect that someone could help me. I had tryed to recreated the Server in Eclipse, deleted the project and create another one, but until now nothing worked.

Thank you!

EDIT

After change my annotation on Controller class to @RequestMapping(value="/olaMundo"), the Tomcat write a stack trace on console, which follows (maybe I missed this stack trace before too):

Please don't post a link to the error, instead add the error content directly to your question. — pczeus, Mar 27 '16 at 21:24
Maybe you should include information on how you are attempting to access the controller method. What is the full URL you are hitting? How have you deployed your application? It looks to be on Tomcat. Is this a war? Exploded war? what is your war name? — pczeus, Mar 27 '16 at 21:26
Edit your question and copy the stack trace that your Tomcat is generating in the Eclipse's tab "Console". 404 error does not explain anything, you can remove the image. Just copy the URL and write down that it generates 404. — RubioRic, Mar 27 '16 at 21:27
I've added the url that I'm trying to hit and yes, I'm using Tomcat 7.0.68. I don't have sure what is a war in Tomcat, but for what I can see in the publish folders of my Tomcat's installation, it's not. — Caio Ferreira, Mar 27 '16 at 21:57
@RubioRic there isn't any stack trace on my console that doesn't regard the deploying and iniatilization of the Tomcat server. There isn't error message on console or other information about the 404 error. — Caio Ferreira, Mar 27 '16 at 22:01
If you are using Eclipse, select your project, right-click, Run As, Run On Server, Select your server, etc ... That's how you deploy your app to the Tomcat server. You have to do that before trying the URL. When the Tomcat is started, it is gonna write in the console. — RubioRic, Mar 27 '16 at 22:09
I try to deploy as you said but the result wasn't different. Have a look at the stack trace that I put above. — Caio Ferreira, Mar 27 '16 at 22:27
@CaioFerreira You have obtained the exception. That's an improvement. Look for what may cause that specific exception. Maybe this helps http://stackoverflow.com/questions/11227395/java-lang-classnotfoundexception-org-springframework-web-servlet-dispatcherserv — RubioRic, Mar 27 '16 at 23:51
UHUL! It worked!! When I found the exception I started to look for posts about that and find some, but none had worked until that! Thank you a lot man! I'm a big fan of MVC and DDD but I'm migrating for C# to Java and don't much yet! Thank all you guys! — Caio Ferreira, Mar 28 '16 at 00:01

Is the jsp you are trying to display called "ok.jsp"? If not this is what your controller is looking for in your views folder when it returns "ok".

Try replacing your @RequestMapping("/olaMundo") with @RequestMapping(value="/olaMundo")
