Project

In the above code, I am always getting HTTP Status 404 - /SpringDemo/index error when I try to run it via http://localhost:8080/SpringDemo/index

What is wrong with the code?

What errors do you get in the logs when you start up your application? — Gergely Bacso
– Gergely Bacso, Commented Feb 4, 2016 at 8:05
@HarshitShrivastava can you enable logs and then see if your context is being loaded at all. Are the request mappings being registered ? Is the XML file being loaded at all. Put in a debug point in the ContextLoader class and then check which location is being loaded in the "initWebApplicationContext" method there and start in debug mode. It is important to understand if the application is being loaded at all. — Gyan

@HarshitShrivastava Try adding a leading / to index.htm - <prop key="/index.htm">indexController</prop> — Omkar Puttagunta

You will need to create the necessary log configuration file set to 'debug' to see what is going on in the Spring MVC framework. — Alan Hay

Change <load-on-startup> element argument and try again.Also add <context:component-scan> for load your bean.I hope this will working for you.

Like :

<load-on-startup>1</load-on-startup>

Try to add to your file dispatcher-servlet.xml this:

  <mvc:annotation-driven />

This:

  <context:annotation-config/>

And this:

  <context:component-scan base-package="SpringDemo" />

And change the return ofthe method to a String like this:

  @RequestMapping("/index")
public String loginWorld(ModelMap model) {

    return "Main";
}

It was obviously missing but still the same issue? Finding hard to understand the problem!!

Harshit Over a year ago

I tried http://localhost:8080/SpringDemo/index & http://localhost:8080/SpringDemo/index.jsp, its not working. It seems it cant even reach to the controller class. Is there any better debugging option so that I can find out where the problem is?

Abdelhak Over a year ago

@HarshitShrivastava tryto add this : <context:annotation-config/> to dispatcher-servlet.xml

Harshit Over a year ago

Added this. Still not working. I think code is correct now but don't understand why it is not working.

@HarshitShrivastava try to post all your material I'll try to run it
