I have a Spring 4 web application (webapp-module.war) working and running locally in eclipse using Java 8, tomcat 8 and JavaConfig (no web.xml):
But when I deploy to tomcat 8 (same version I am using locally in eclipse) on a remote Ubuntu server I get:
I verified host and port which are correct. There is no error in the log (/var/lib/tomcat8/logs/catalina.out)

I took a look at: Spring Java Config: Tomcat deploy without web.xml but it does not really provide a solution.
Details on my project below:
Sources
Config.java
@Configuration // Marks this class as configuration // Specifies which package to scan @ComponentScan("com.samples") // Enables Spring's annotations @EnableWebMvc public class Config { @Bean public UrlBasedViewResolver setupViewResolver() { UrlBasedViewResolver resolver = new UrlBasedViewResolver(); resolver.setPrefix("/WEB-INF/jsp/"); resolver.setSuffix(".jsp"); resolver.setViewClass(JstlView.class); return resolver; } } WebInitializer.java
public class WebInitializer implements WebApplicationInitializer { @Override public void onStartup(ServletContext servletContext) throws ServletException { AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext(); ctx.register(Config.class); ctx.setServletContext(servletContext); Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx)); servlet.addMapping("/"); servlet.setLoadOnStartup(1); } } HelloController.java
@Controller public class HelloController { @RequestMapping("/") public String home() { return "index"; } @RequestMapping("/hello") public String showhello(ModelMap model) { model.addAttribute("message", "Hello Spring MVC Framework!"); return "hello"; } } 3 Answers

Sorry previously I was too hasty
It seems that spring context is not at all loaded.
I guess the problem is in this piece of code:
public class WebInitializer implements WebApplicationInitializer { @Override public void onStartup(ServletContext servletContext) throws ServletException { AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext(); ctx.register(Config.class); ctx.setServletContext(servletContext); Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx)); servlet.addMapping("/"); servlet.setLoadOnStartup(1); } } You used ctx.register(Config.class);
In any case I always used this kind of initialization:
public class AppInitializer implements WebApplicationInitializer { @Override public void onStartup(ServletContext servletContext) throws ServletException { // Create the 'root' Spring application context AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext(); rootContext.scan("com.spring"); rootContext.setConfigLocations(new String[]{"com.spring.config.WebAppContextConfig", "com.spring.config.AppConfig"}); // Manages the lifecycle of the root application context servletContext.addListener(new ContextLoaderListener(rootContext)); // Declare dispatcher servlet. Handles requests into the application ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new DispatcherServlet(rootContext)); dispatcher.setLoadOnStartup(1); dispatcher.addMapping("/"); } } As you can see I used rootContext.setConfigLocations in order to specify where to find the spring configuration classes
In any case Here you can find a working sample I successfully deployed it on tomcat 8.0.39 and 8.5.4
Hope it's useful

Add finalName as ROOT in your pom.xml. This will create ROOT.war file in your target folder.
<build> <plugins> <!--All plugins are here --> </plugins> <finalName>ROOT</finalName> </build> After that if you deploy ROOT.war file in your tomcat. Then your accessing url will be http://localhost:8080
Hope it will solve your issue.
For further checking, please go through http://localhost:8080/manager/html it will call for username and password. Check that is set or not.
If not set, please go through this tutorial: Can't access Tomcat 8 Manager App as suggested by E-Riz
For full example, go through this tutorial: http://websystique.com/springmvc/spring-4-mvc-helloworld-tutorial-annotation-javaconfig-full-example/

In case if all the controllers where initialised you will see the Mapped URL in tomcat server startup logs, can you check that?
INFO: Mapped "{[/rama],methods=[GET]}" onto public java.lang.String com.javacodegeeks.examples.controller.MainController.rama() INFO: Mapped URL path [/resources/static/js/**] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] INFO: Mapped URL path [/resources/static/css/**] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] INFO: Mapped URL path [/resources/static/views/**] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] INFO: Mapped URL path [/resources/static/**] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] INFO: Mapped URL path [/webjars/**] onto handler of type [class org.springframework.web.servlet.resource.ResourceHttpRequestHandler] INFO: Mapped URL path [/**] onto handler of type [class org.springframework.web.servlet.resource.DefaultServletHttpRequestHandler]
