How to convert old Java Servlets to OSGi "Servlet" Bundles

Question

Hello I'm looking for some help/insight on the best way to convert some of our old Java Servlet code into new OSGi Bundles that can be accessed as servlets.  I'd like to be able to install the new bundles then access them on one of our CQ instance using something like "/servlet/servlet_name".
So far I've been able to create a new bundle, and install it into CQ but I haven't been able to access the bundle at the servlet mapping URL that I would expect.  So far what I've found online has lead me to believe that I need to use the Felix Annotations to describe my servlet.
@Component(immediate = true, metatype = true, label = "Servlet Name")
@Service
@Properties({
    @Property(name = Constants.SERVICE_DESCRIPTION, value = "Servlet Name"),
    @Property(name = "sling.servlet.methods", value={"GET"}),
    @Property(name = "sling.servlet.paths", value = "/servlet/my_servlet_mapping"),
    @Property(name = Constants.SERVICE_VENDOR, value = "VendorName")
public class TellAFriend extends HttpServlet {...
public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException, ServletException
Once I have this installed, and running without an error in the logs for CQ I tried to go on my local instance to http://localhost:4502/servlet/my_servlet_mapping but I only get 404 Resource Not Found errors.  I've even gone to the Sling Resource Resolver and it doesn't resolve to anything either.
Is there more than the Servlet Information need into the Annotations to convert "old" code into a new OSGi Servlet Mapped Bundle?

I must be missing something else configuration wise since I created a new Servlet basically using the code you provided above.  I deployed it as part of the bundle that I'm trying to create.
The bundle installs and stars fine but I still can't access the servlet.  Are there CRXDE based configurations that are requried too to configure Servlets. 
Here's my test servlet file.  I tried going to http://localhost:4502/servlet/TestCQServlet and just get the same 404 error I'm getting for the other 2 Servlets Java classes in my Bundle.
import java.io.IOException;
import javax.servlet.ServletException;
import org.apache.felix.scr.annotations.sling.SlingServlet;
import org.apache.sling.api.SlingHttpServletRequest;
import org.apache.sling.api.SlingHttpServletResponse;
import org.apache.sling.api.servlets.SlingSafeMethodsServlet;
@SlingServlet(paths = "/servlet/TestCQServlet", methods = "GET")
public class TestCQServlet extends SlingSafeMethodsServlet {
    // @Reference
    // private Repository repository;
    private static final long serialVersionUID = 6239754936223276983L;
    @Override
    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
        response.setHeader("Content-Type", "application/json");
        response.getWriter().print("whatever");
