Spring MVC - HTTP Status 404 - The origin server did not find a current representation for the target resource

Attempting to create a Spring MVC hello world web app. It is currently returning HTTP Status 404. 404 means it can't find the file, but I'm not sure why. I think my servlet.xml is pointing to the appropriate folder (component-scan). I think all the files are named correctly(no typos). See the picture for the error.

package helloworld;

public String showPage() {
return "hello-world";
}
}
hello-world.jsp
<!DOCTYPE html>

The servlet.xml and the web.xml were not under WEB-INF.

The RequestMapping is pointed to "/" in the controller. try making a call to http://localhost:8080/

No mapping found with URI [/SampleSpringMaven/hello.html] in DispatcherServlet with name 'dispatcher'

Im new to Spring MVC creating basic hello world example for Spring MVC but getting the message:
HNo Mapping found for HTTP request with URI [/SampleSpringMaven/hello.html] in DispatcherServlet with name dispatcher
index.jsp
<html>
<body>
<h2>Hello World!</h2>
Call Controller

</html>
Then I Created web.xml

My index.jsp contains a simple:

Not sure why its not deploying, any help is appreciated thanks.

Make the following change to your web.xml

I've found the answer, it was a simple mistake on my end. I was not including the necessary namespace files and their corresponding schemaLocations in the dispatcher-servlet.xml, namely:
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"

return "hello";
}
}
Here is my jsp file:

<body>
<h1>Message : ${message}</h1>

Any help?

assuming FirstSpringMVCApp your application name and you have deployed your application in a server which is running on the port 8080 then you should use the following URL to run the application
localhost:8080/FirstSpringMVCApp/hellospring

resolved it:
#RequestMapping(value="/")
public String gotoIndex(){
return "index";
}
and its work!!

${HelloMessage}

</html>

In web.xml when we replace "*htm" with "/", then the error of resource not available was solved.

The original issue is because you're sending all requests ending *.htm to Spring:
<servlet-mapping>
<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
But your controller is mapped to /hello without an extension.
Change the #RequestMapping in your controller to:
#RequestMapping(value="/hello.htm",method=RequestMethod.GET)

If you are accessing http://localhost:8080/HelloWorldExampleWithSpring3MVCInEclipse/, you need to create a WebContent/index.jsp in your project to make this URL work.
index.jsp:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<jsp:forward page="/hello.htm"></jsp:forward>
See the sample code here.
