I am trying to create a new spring mvc project which just displays "This is a sample spring MVC Demo Page". When running, I get a 404 error
I created a new Spring MVC project, added application server as Tomcat and gave it the path to find tomcat, added sdk as well
In the new project, Created a package under the src folder called "com.luv2code.springdemo". Created a controller class inside this package called HomeController.
Contents of the HomeController look like this:
package com.luv2code.springdemo;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HomeController {
@RequestMapping("/")
public String showPage(){
return "index";
}
}
Created a folder inside the web->WEB-INF called "view", inside view I moved the index.jsp and the contents of index.jsp look like this
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Spring Demo</title>
</head>
<body>
<h1>This is a sample spring MVC Demo Page</h1>
</body>
</html>
web.xml file inside the WEB-INF looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
id="WebApp_ID" version="3.1">
<display-name>spring-mvc-demo</display-name>

<!-- Step 2: Set up URL mapping for Spring MVC Dispatcher Servlet -->

I have another xml file called spring-mvc-demo-servlet.xml under the WEB-INF and its contents are:
<?xml version="1.0" encoding="UTF-8"?>

I have a dispatcherservlet.xml and an applicationcontext.xml that was created automatically when I created the project as a spring mvc project.
The tomcat Localhost logs show error as
08-Aug-2017 10:37:34.263 INFO [RMI TCP Connection(5)-127.0.0.1] org.apache.catalina.core.ApplicationContext.log Marking servlet [dispatcher] as unavailable

Description for 404 error says: The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

@Jdarvin, Have you managed to find out the reason for the problem?
Ultimately this means that the web server cannot find the indicated object. This is because the jars are missing in the deployment artifact.
The way that I fixed this was to add it to the artifact.
There you should see your artifact. i.e. something like project:Web explode
In the right side panel, you should see Available items / lib
In the context menu, you should see the option ('Put ... / Extract ...). These will place the jars in the artifact that is being created.
