To run the tomcat, which you installed(not the embedded one- and you need to run the manager portal of tomcat for auto deploy from maven
In eclipse ->
Tomcat v7.0 Server at localhost.server - take properties ->and click "switch location"
open it -> “server location” select “use Tomcat Installation(takes control of tomcat installation”
now right click your spring project and run as “maven build “ -> tomcat7:redeploy will do the magic
