Okay,I am using spring MVC,jsp,Java Based Configuration. where index.jsp is my landing page which is inside WEB-INF/jsp/index.jsp. I am aware that jsp files inside WEB-INF cannot be accessed directly through URL.So, i have set my Controller with @GetMapping(“/”) that return string “index” which is then handled by InternalResourceViewResolver, prefix as”/WEB-INF/jsp/” and suffix as”.jsp”.
When i run my app, “http://localhost:14639/project/” this is my URL and i get 404 not found,
“The requested resource [/project/] is not available”. I have “Sysout” statement inside the controller with @GetMapping(“/”) mapping, it isn’t being invoked and also there is not any logs on console rather than tomcat starting.
and context path is “project”.
<code>package Configurations;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
@Configuration
@ComponentScan(basePackages="controller")
public class MainConfig extends AbstractAnnotationConfigDispatcherServletInitializer{
@Override
protected Class<?>[] getRootConfigClasses() {
// TODO Auto-generated method stub
return new Class<?>[] {javaBasedConfig.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
// TODO Auto-generated method stub
return new Class<?>[] {WebConfig.class};
}
@Override
protected String[] getServletMappings() {
// TODO Auto-generated method stub
return new String[]{"/"};
}
}
</code>

}
that is my DispatcherServlet

that is my WebConfigurations

That is my index.jsp
<code>package controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class viewsController {
@GetMapping("/")
public String home() {
System.out.println("i am working..");
return "index"; // This maps to /WEB-INF/jsp/index.jsp
}
}
</code>
<code>package controller;
import org.springframework.stereotype.Controller;

public class viewsController {

return "index"; // This maps to /WEB-INF/jsp/index.jsp

return "index"; // This maps to /WEB-INF/jsp/index.jsp
}
}
That is my viewsController.
and,
this is my structure

Alright, solved.
I don’t know how but there was new web module automatically creating in tomcat module, may be because i was using”/project/signin” as action.
I deleted tomcat from eclipse and readded it and solved
