SpringMVC URI mapping no more working

Question

I'm sorry this is a kind of duplicate question of this other one already asked by me: Spring MVC Rest: No mapping found for HTTP request with URI [/ecommerce-api/rest/checkout] in DispatcherServlet

But I'm getting mad, since the problem after while appears again. When everything seems to be working suddenly it stops :-(

I'm trying to build an API with SpringMVC, I'm developing using STS 3.3.0 and testing with the rest shell 1.2.1.

The command I'm issuing is:

get ecommerce-api/rest/checkout

and the error I got is:

2013-09-10 11:56:49,614 DEBUG [tomcat-http--9] servlet.DispatcherServlet (DispatcherServlet.java:823) - DispatcherServlet with name 'api-dispatcher' processing GET request for [/ecommerce-api/rest/checkout] 2013-09-10 11:56:49,615 DEBUG [tomcat-http--9] handler.AbstractHandlerMethodMapping (AbstractHandlerMethodMapping.java:220) - Looking up handler method for path /checkout 2013-09-10 11:56:49,615 DEBUG [tomcat-http--9] handler.AbstractHandlerMethodMapping (AbstractHandlerMethodMapping.java:230) - Did not find handler method for [/checkout] 2013-09-10 11:56:49,615 WARN [tomcat-http--9] servlet.DispatcherServlet (DispatcherServlet.java:1108) - No mapping found for HTTP request with URI [/ecommerce-api/rest/checkout] in DispatcherServlet with name 'api-dispatcher' 2013-09-10 11:56:49,615 DEBUG [tomcat-http--9] servlet.FrameworkServlet (FrameworkServlet.java:966) - Successfully completed request

Until yesterday everything was working absolutely fine, this morning I tried to add some more functionalities to my really basic controller and I got the above error.

What I tried without success:

1) reverting to last working version from git repositories

2) deploying the war package in a clean Tomcat install (trying to have avoid any possible issue related to Eclipse)

3) unpublishing the package from the vFabric within STS - cleaning its working dir - cleaning the project - deploying it again

I copy there my *.xml and java files, even if they seems to be ok since they worked since a couple of hours ago.

Any idea or suggestion will be really appreciated.
