For securing Tomcat from hackers, it's recommended that we try a few steps at hiding the tomcat version information. The OWASP project suggests a few steps. <a href="https://www.owasp.org/index.php/Securing_tomcat" rel="nofollow">https://www.owasp.org/index.php/Securing_tomcat</a> . If a tomcat installation is thus protected, then only 1 of the above answers will show the version of tomcat. i.e going through the $TOMCAT_HOME\RELEASE-NOTES file where the version number is clearly announced.

I had one such protected server and only the RELEASE-NOTES file revealed the version of the tomcat. all other techniques failed to reveal the version info.

One can run on subtle weird behaviors due to (operating system) environment variables and (Java) system properties being set to unexpected values. I had a situation where due to an outdated Tomcat <code>setenv.sh</code>, A Tomcat 8 started with classes from a Tomcat 7 on the classpath. Make sure that in the process command line options such as <code>-Dcatalina.base</code>, <code>-Dcatalina.home</code> and <code>-classpath</code> make sense.

For Windows PowerShell command-line method of checking running version(s) of Tomcat service:
<pre><code>(get-service Tomcat*).DisplayName

Sample output...
<pre><code>Apache Tomcat 8.5 Tomcat8

If also want to know additional details including the location of folder where service running at:

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 <a href="http://appfuse.org/display/APF/FAQ#FAQ-useexistingtomcat" rel="nofollow noreferrer">appfuse FAQ</a>.
After deploying with <code>mvn cargo:run</code>, 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 <code>$CATALINA_HOME</code> 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, <a href="https://stackoverflow.com/a/21773359/247869">@Tech Junkie</a> and <a href="https://stackoverflow.com/a/14925114/247869">@CPU 100</a> really have the best answer, but not for the scenario I was encountered. (I was wanting to know if <code>mvn cargo:run</code> runs my installed tomcat or a &quot;project embeded&quot; tomcat) <code>:)</code>
