Embedded Tomcat + Spring file-upload: HTTP 404

I can open myApp throw Internet Browser if I start it via Eclipse, but, although I can start the Embedded server throw command line (java -jar myApp.jar) I am getting HTTP Status 404. Probably some issue with context but I can't figure out what is wrong.

Kindly, see below the structure in Eclipse and in myApp.jar. The application is basically compound by 5 files: two placed in com.mycompany.myapp.batchs.AuthFileUpload (App.class with main method and FileUploadController.class as a very simple controller). Other three files, App-servlet.xml, web.xml and index.jsp placed in WEB-INF.

Other possible reason can be I should point straigh to the classes in "tomcat.addWebapp("/", "the_place_where_classes_can_be_found_in_myApp.jar)". If so, how can I do it?

Index.jsp and the FileUploadController.java are too simple so it is pointless show both here.

App class

 public static void main(String[] args) throws IOException,
                 ServletException, LifecycleException {
          Tomcat tomcat = new Tomcat();

          tomcat.setPort(8080);


          tomcat.setBaseDir("C:\\temp\\");
          tomcat.addWebapp("/", "C:\\temp\\");
          tomcat.start();
          tomcat.getServer().await();

   }

App-servlet.xml

<context:component-scan base-package="com.mycompany.myapp.batchs.AuthFileUpload" />

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
 <property name="prefix" value="/WEB-INF/" />
 <property name="suffix" value=".jsp" />
</bean>

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />

web.xml

Your app structure is wrong. Maven jar projects do not have a src/main/webapp folder.

On the other hand, in order to the container (not the classloader) finding the web resources (index.jsp) of your application in a jar, you must declare in web.xml that it is a servlet 3.0 webapp and place the resources in src/main/resources/META-INF/resources. See here for more details.

Try this:

Ensure webapp is servlet 3.0 and index.jsp is a welcome-file

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
    ...
</web-app>

Refactor the structure to:

|-- src/main/resources
|   |-- WEB-INF/App-servlet.xml
|   |-- META-INF/resources
|   |   | --  WEB-INF/web.xml
|   |   | --  index.jsp
