Fails running spring mvc and eclipse's tomcat

I'm facing a Spring 3 MVC + Tomcat 7 stack and using Eclipse to do the job. In Eclipse (Luna) I installed a new server pointing to my Tomcat installation. To keep .war the smaller as possible, a lot of libs are embedded into %TOMCAT_HOME%/shared. I created a new Tomcat server into Eclipse pointing the %TOMCAT_HOME%, I want to use it to run my maven + Spring 3 webapp. When I run my webapp as Run on Server I got this

When I deploy the webapp directly under %TOMCAT_HOME%/webapp it works fine. It looks like my run configuration can't see the %TOMCAT_HOME%/shared directory. I also add this param as run configuration VM argument:

-Dshared.loader="/my-tomcat-home/shared"

or adding .jars in %TOMCAT_HOME%/shared directly to the run configuration classpath but problem persists.
