Spring boot and tomcat7 does not working

I followed this guide http://ift.tt/Jb3BXl, so i made a simple restful web service using the following scenario:

-Netbeans 8.1 -Tomcat7 -Maven

my build and deploy works, but when i access the path localhost:8080/WsTaxiShare/hello nothing appears just a blank page, not even a error request or HTTP 404(not found), i don't know what happening could anyone help me?
