I don't know why ´http:localhost:8080/ejemplospring/mail.html´ doesn't match with the url pattern .html?, I get a 404 error and if I try with / or / I get the same error.
Try to uncomment
<context:component-scan base-package="com.tutorial.ejemplospring" />
Seems that it is not finding the Controller and therefore not registering the Mapping.
Why do you have your ComponentScan commented out? You need to enable this (uncomment), so it finds your #Controller
This
<!-- <context:component-scan base-package="com.tutorial.ejemplospring" />-->
needs to be:
<context:component-scan base-package="com.tutorial.ejemplospring" />
First issue is that you have to enable component scanning for the beans to be created.
Second one is that Spring MVC by default ignores the the extension in the URL, as it's to be used for specific purposes like .json/.xml would indicate to Spring MVC that you need data in JSON or XML format.
So your URL should be mail.html.someExtension ie. mail.html.do.
If you don't want to do that and you absolutely must have the extension as it is then you can use following configuration to enable extension mapping.
<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
<property name="favorPathExtension" value="false" />
</bean>
Otherwise simplest way would be to just use some simple URL like /mail without any extension.

I have a problem with my demo app.
Why is the application launch index.jsp not main-menu.jsp as I mapped in HomeController? And as I see via debugger HomeController is not used.
Where is the problem and how can I fix it?
Thanks

I am not so sure what is the problem but all I could do is suggest you some alternative. Try configuring your controller as:
public class HomeController extends AbstractController{
#Override
protected ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelAndView model = new ModelAndView("main-menu");
model.addObject("msg", "Lets Check");
return model;

I have a problem with Spring not picking up the controller. I've used maven webapp archetype to create a project in Eclipse and it worked fine - I could access the index.jsp page. Problems started when I added Spring to the project. (context, controller, etc.)
I'm using Eclipse Mars, Tomcat 8, maven 3.3.3 and Spring 4.2.2
Here is what I see in the log (probably only third line matters):
Looking for matching resources in directory tree [C:\Users\dima\spring_workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\cte\WEB-INF\classes\com\company\dept\demo\cte\controller]

Resolved location pattern [classpath*:com/company/dept/demo/cte/controller/**/*.class] to resources []
Instead of something like

As a result I get 404 when trying to open the web page. These are the files:

Thanks.
Update:
WAR file is correct but for some reason when it is deployed to Tomcat controller class isn't copied.
Is it your full web.xml , Because you have to add your dispatcher servlet reference to web.xml , Like below -
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>

<load-on-startup>1</load-on-startup>
</servlet>
I am starting with Spring Framework and want to do a HelloWorld with annotatios, I've made it work creating a controller and a view, basic hello work I guess; however, I want to use annotatios since I can not use SimpleFormController any more (deprecated).
The error I am getting is Estado HTTP 404 - /av/index.jsp
I am using Netbeans and I am basing the example on the basic template It provides. I have the following files, I am pretty sure it is a missconfiguration but I can't find anything that would help me so far. Thanks in advance.

I have setup Spring MVC 3.0 & Hibernate on Apache Tomcat and got the application to launch without any errors.
However I’m available to route requests from my (welcome file) redirect.jsp to the home controller (/Home).
This is what is supposed to happen:
Welcome file redirect.jsp sends request using <%response.sendRedirect(/Home)%>
My home controller (/home) returns the view index which is in WEB-INF/views
This is my web.xml: I mapped the home controller (/Home) via annotation and inweb.xml however its still not being found.

However I’m getting a 404 Error,
The requested resource (/Home) is not available.
What I would actually like to do is to remove the redirect.jsp, have the application go to \Home controller on launch/startup, and the \Home controller returns the index view or any other view.
The first thing I noticed is that in your web.xml, you call your config location applicationContext.xml, but you later described it as application-context.xml. Make sure it is actually named applicationContext.xml. Also, you can remove the "Home" servlet from your web.xml; this will be handled by Spring through your dispatcherServlet. Finally, in your SimpleUrlHandlerMapping, you define the mapping to be index.html, but you need to also define Home if you want requests to Home to be handled by indexController. Hope that helps.
