Application starts index.jsp not mail-menu.jsp

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 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.

Http Status 404- the rest controller is not mapped corectly? [duplicate]

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.

You are missing
<mvc:annotation-driven />
in your config dispatcher-servlet.xml
See here for more info

You mapped the path /index.do in your controller, so you have to access it with the following url: http://localhost/av/index.do

<mvc:annotation-driven/> will solve out your problem.

Please try this
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
add an entry in dispatcher-servlet.xml

in your disapatcher-servlet.xml, add
<mvc:annotation-driven/> to enable annotation driven handler mapping.

Try to go through one of my tutorials:
Creation of a simple Controller with java-based config
I hope I will get success with it

Can't configure Spring MVC application

I have big problem with configuring Spring MVC application. No matter what I write in configuration xmls I get 404 while reaching localhost/appname/ or localhost/appname/register . Why that happens? Read tutorials for MVC in Maven and it looks like I'm doing everything as they says.

Things you can change to make it more basic:-
Remove
contextConfigLocation
/WEB-INF/dispatcher-servlet.xml
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
put your web.xml and dispatcher-servlet.xml at same path.
No need of
<context:annotation-config /> as it is already taken care by component-scan. See here:- Difference between <context:annotation-config> vs <context:component-scan> and <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>
Make sure register.jsp is present in /WEB-INF/jsp/register.jsp.
If issue still does not get solved you need to share your server logs.

Stuck at Spring MVC tutorial for newbies

I am stuck on this Spring MVC tutorial for newbies:
http://sites.google.com/site/springmvcnetbeans/step-by-step/
I am the point 1.12 "Try out application". When I put in my address bar hello.htm it doesn't work, but hello.jsp works. But I guess point was somehow to hide this JSP extension.
I followed tutorial precisely.
What might I have done wrong?
skaffman suggested posting web.xml and servlet mapping xml file, so here they are. I added only what tutorial said (but with another package name, rest is generated by NetBeans)

I can see several differences. The file in the tutorial is called springapp-servlet.xml, not springsample-servlet.xml (see step 1.8), and it only contains one bean, the hello.htm bean. There is no mention of springsample-servlet.xml anywhere in the whole thing.

The tutorial tells you to place the file in the webapp root web/hello.jsp but you've told spring to look for it in /WEB-INF/jsp/hello.jsp Did you move the file into that folder? The fact that you can find it at /springsample/hello.jsp would indicate you did not.
