Run servlet before anything else

I have a dynamic web project with a servlet (structure below).

When right-clicking HomeServlet.java --> Run as --> Run on Server --> Tomcat...
It runs fine with the URL: http://localhost:8080/JSTLTest/HomeServlet

When right-clicking JSTLTest --> Run as --> Run on Server --> Tomcat...
I get an error and this URL is used: http://localhost:8080/JSTLTest/

The problem is, i want to deploy it on a server like AWS elastic beanstalk and i guess it doesn't work because he won't use the servlet to start, like:
http://ift.tt/1LNAFDvHomeServlet

Is my web.xml wrong?

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://ift.tt/ra1lAU"
    xmlns="http://ift.tt/19L2NlC"
    xsi:schemaLocation="http://ift.tt/19L2NlC http://ift.tt/1drxgYl"
