Servlet URL 404'ing, although JSP files work fine

Question

Setup: Tomcat 7 Server, Eclipse Mars Milestone 3

The problem: When attempting to run Servlet files or connect to them the files 404. Although I can connect perfectly fine to JSP files it is just all servlet files which 404. Picture below.

Also should mention this effects all Servlets, not just one or two ALL.

I believe this is a local problem as a colleague is running the next same setup on another machine, although the servlet is successfully found.

This is the log from startup although no apparent error is show either on startup or on the load of a servlets url.

I'm using servlet mapping within the servlets to define the URL IE @WebServlet("/Sterling")

Question: What could be causing this and how can I fix it? Thank you.

Deployment Assembly Setup

Case-sensitive, would have expected urlPatterns={"/sterling"} — Joop Eggen
That case is working fine on the live environment as well as my colleagues environment. — Jack
@BalusC Yeah they all say that, I was just attempting to keep it private but that's gone now. To clarify where it says redacted it says what you called it. — Jack

This is a not found error. Your log shows no error so it is quite simple, your deploy does not reach desired servlets.

There is no enough info to determine the cause, but due to you can reach JSP files, I would check if you have configured correctly servlets into WEB-INF/web.xml descriptor.

EDIT

As you have just edited your question, I can tell you what is your problem. You have not configured servlets ... Configure the servlets you want as following:

    <servlet>
            <servlet-name>Servlet Name</servlet-name>
            <servlet-class>path.to.ServletClass</servlet-class>
            <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
            <servlet-name>Servlet Name</servlet-name>
            <url-pattern>URL-PATTERN</url-pattern>
    </servlet-mapping>

EDIT 2

After your edition, I didn't see that you have used annotations, obviously if you have servlet annotated you don't need this configuration.

EDIT 3

Make sure your web.xml has the right schema version, other way it could make your app to ignore annotations.

<web-app 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"
     version="3.0">

I suppose your servlet class inherits from HttpServlet, right?
