maven and spring mvc is not working? - spring

Question

I'm trying to build an application using Spring MVC and Maven 3.0 within Eclipse using the webapp. I'm not able to get to the initial page, or navigate to any other pages from there w/out getting a 404 error. Please let me know if there's something I'm missing. Thanks!

Answer to the questions:
This is the code I'm using.
The #Controller annotation must be there.
As I said before I get :
HTTP Status 404 - /guard_weblayer/ type Status report message /guard_weblayer/
description The requested resource (/guard_weblayer/) is not available.
Apache Tomcat/7.0.25
I use a restfule design, a domainlayer, datalayer and weblayer. Can it effecting the weblayer?

Answer 1

You might want to start over and use an example from springbyexample. It contains everything you need in a understandable fashion (and its in maven as well.)
Most likely that's easier than debugging the current code.
