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) :)

if you can upload a JSP file you may print out some info like in this example: http://www.bestdesigns.co.in/blog/check-jsp-tomcat-version — wemu, Feb 17 '13 at 20:41
right! you got the answer, it's indeed 7.0.27 which I want. please post it as an answer — Yichz, Feb 17 '13 at 21:17

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.

This should be tag as the correct answer. I don't see why you need to write a JSP and deploy it in order to determine the tomcat version. This answer can has wider audience not just programmers, such as system admin just wanting to know exact tomcat version. – Itherael Nov 01 '17 at 17:51

Try parsing or executing the Tomcat_home/bin directory and look for a script named version.sh or version.bat depending on your operating system.
Execute the script ./version.sh or version.bat

If there are no version.bat or version.sh then use a tool to unzipping JAR files (\tomcat\server\lib\catalina.jar) and look in the file org\apache\catalina\util\lib\ServerInfo.properties. the version defined under "server.info=".

I had this challenge when working on an Ubuntu 18.04 Linux server.

Here's how I fixed it:

Run the command below to determine the location of your version.sh file:

sudo find / -name "version.sh"

For me the output was:

/opt/tomcat/bin/version.sh

Then, using the output, run the file (version.sh) as a shell script (sh):

sh /opt/tomcat/bin/version.sh

That's all.

I hope this helps

Well `sudo updatedb && sudo locate version.sh` is probably faster then searching your whole disk with find. Upvote anyway! Especially since your version with find also works in containers. – qräbnö May 14 '21 at 10:47

Using the release notes

In the main Tomcat folder you can find the RELEASE-NOTES file which contains the following lines (~line 20-21):

                Apache Tomcat Version 8.0.22
                        Release Notes

Or you can get the same information using command line:

Windows:

type RELEASE-NOTES | find "Apache Tomcat Version"

Output:

             Apache Tomcat Version 8.0.22

Linux:

cat RELEASE-NOTES | grep "Apache Tomcat Version"

Output:

             Apache Tomcat Version 8.0.22

If you set the environtment variable - %CATALINA_HOME%, then Windows :

Alternatively,

To find out the Tomcat version, find this file – version.sh for *nix or version.bat for Windows. This version.sh file is normally located in the Tomcat bin folder.

If you are not sure where is the version.sh file, try this command :

I know it is maybe too late for this, but this could be usefull: If you try to know Apache Tomcat Server version from Java code, you can use:

from a HttpServlet:

protected void doGet(HttpServletRequest request, HttpServletResponse response) {
    getServletContext().getServerInfo()
}

from a ServletContextListener:

public void contextInitialized(ServletContextEvent event)  { 
    event.getServletContext().getServerInfo();

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. https://www.owasp.org/index.php/Securing_tomcat . 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.

These Following 4 ways can be used to find out Apache Tomcat Version in Linux:

1). Linux via Version Script in Tomcat Bin Directory:

Locate the Tomcat`s bin Directory that is being used
Check for version.sh script exists, i.e. ll version.sh
Execute the script either way: sh version.sh OR ./version.sh

This will output you sample as below:

2). Check Tomcat Version in Linux Command Line

ps -ef |grep -i tomcat // this is will output and you will need to eye-ball to find version, sample below

3). Get Tomcat version via Catalina.jar

Execute the following CMD in terminal, you will need to locate Lib folder in Tomcat

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

4). Get Tomcat version through JSP

Create JSP page with the below code
Then try to open the JSP via Tomcat in the Browser
This will output the Tomcat Version you are running.

Tomcat Version : <%= application.getServerInfo() %>
Servlet Specification Version : <%= application.getMajorVersion() %>. <%= application.getMinorVersion() %>
JSP version : <%=JspFactory.getDefaultFactory().getEngineInfo().getSpecificationVersion() %>

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 setenv.sh, A Tomcat 8 started with classes from a Tomcat 7 on the classpath. Make sure that in the process command line options such as -Dcatalina.base, -Dcatalina.home and -classpath make sense.

Simply start tomcat and search for "Server version name" in catalina.logs and you will get version of your tomcat. For example:

"Mar 07, 2019 11:25:40 AM org.apache.catalina.startup.VersionLoggerListener log INFO: Server version name: Apache Tomcat/9.0.16"

Sometimes the bin/version.sh script in tomcat directory still doesn't show a numerical version. E.g. it can just show: "Server version: WebServer". And other mentioned opportunities (checking path, checking logs, release notes, tomcat root page output) don't work neither. In that case (you should still have read access to tomcat's directory):

take catalina.jar from tomcat's lib directory.
extract it
take a look inside org/apache/catalina/util/ServerInfo.properties

it can contain what you expect (server.info and server.number fields)
