Eclipse: The selection did not contain any resource that can run on a server

I am not able to run maven java web application project to the configured tomcat within eclipse ide.

Initially I could right click on the project and run it on tomcat server but ever since I shared the project to a repository I am not able to do that.

I disconnected the project form the repository and now I I dont even see the Run as -> Run on Server option inside eclipse ide.

I am using m2e plugin version .0.12.1 and eclipse helios and tomcat 6.

Could someone help me understand what am I missing here?

Thanks.
