I created a Spring-MVC project.

web.xml:

<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/soundmails</url-pattern>
</servlet-mapping>

mvc-dispatcher-servlet.xml

<?xml version="1.0"?>

<bean id="multipartResolver" class="org.gmr.web.multipart.GMultipartResolver">
    <property name="maxUploadSize" value="1048576" />
</bean>

<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <!-- property name="location">

        <list>
            <ref bean="jacksonMessageConverter"/>
        </list>
    </property>
</bean>
</beans>

The controller has this code: ProjectController.java

@Controller
@RequestMapping("/soundmails")
public class FileUploadController {
    @RequestMapping(value="/test", method=RequestMethod.GET)
    public @ResponseBody String test() {
        System.out.println("Hai");
        return "Hai";
    }
}

I am using Google App Engine in my local machine to test this. I am getting these in my log:

[INFO] Oct 24, 2013 1:54:18 AM com.google.appengine.tools.development.LocalResourceFileServlet doGet [INFO] WARNING: No file found for: /soundmails/test

I tried /soundmails/soundmails/test as well. That is also giving the same error.

I am using Spring 3.1.0.RELEASE

Can someone help me figure out what I am missing - /soundmails/test is giving 404 error.

Edit

I am unable to enable DEBUG logs for this. For some reason, it is not taking log level configured in logging.properties

But I observed something interesting:

1) If I map the request to empty string (value = "")

@RequestMapping(value="", method=RequestMethod.GET)
public @ResponseBody String test() {
    System.out.println("Hai");
    return "Hai";
}

Then, when I try to access 127.0.0.1/soundmails, it works fine (returns string "Hai").

2) When I have value="/test"

@RequestMapping(value="/test", method=RequestMethod.GET)
public @ResponseBody String test() {
    System.out.println("Hai");
    return "Hai";
}

and I try to access 127.0.0.1/soundmails/test, it is giving HTTP 404. This is weird.
