Tomcat How to find out running tomcat version

Question

I m trying to get Appfuse   tomcat   jRebel working   Appfuse by default uses Cargo to download tomcat  ver  7 0 33  and deploy the application to it  I wish to use an already installed tomcat  ver  7 0 27  instead of the downloaded one  I made the change following the appfuse FAQ   After deploying with mvn cargo run  how can I know that the actual running tomcat is indeed 7 0 27    I used to type a wrong URL  ex  localhost 8080 dfsfsdf  to see it in the error page  but now it shows nothing   My  CATALINA HOME points to my own tomcat 7 0 27  sorry forgot to mention  it s for Windows  Update   Since this question had become somehow popular  I would like to explain why that accepted answer  simple  it was the first one which solved my problem    looking at the title of the question    Tech Junkie and  CPU 100 really have the best answer  but not for the scenario I was encountered   I was wanting to know if mvn cargo run runs my installed tomcat or a  project embeded  tomcat
