java - 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.

I am 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) :)

Answer 1

Though this is not recent, I thought, my answer can still help others:

cd tomcat/lib 
java -cp catalina.jar org.apache.catalina.util.ServerInfo

and that's it.
