Tomcat: How to find out running Tomcat version?

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: bestdesigns.co.in/blog/check-jsp-tomcat-version – Invigilate

if you can upload a JSP file you may print out some info like in this example: bestdesigns.co.in/blog/check-jsp-tomcat-version

Save this code into a file called tomcat_version.jsp:

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

When you access, http://example.com/tomcat_version.jsp, the output should look similar to:

Tomcat Version : Apache Tomcat/5.5.25
Servlet Specification Version : 2.4
JSP version: 2.0

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.

@sv. looks like there is a java version clash in your solaris server. use appropriate java version to invoke. – Curst
You're right, the default Java on the system was 1.5. After I pointed to 1.7 I get the correct output on Solaris as well. – Beeler
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. – Chamfer

  1. 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.
  2. 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=".

You can simply open http://localhost:8080/ in your web browser and this will open Tomcat welcome page that shows running Tomcat version like this:

Apache Tomcat/7.0.42

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. – Inclined

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

This one command which you can check almost everything:

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

or 

tomcat/bin/catalina.sh version

And the output looks like this

The version of currently running Tomcat

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

>> cd %CATALINA_HOME%\bin
>> version

Alternatively, 

java.exe -cp lib\catalina.jar org.apache.catalina.util.ServerInfo

MY SETTING --- Hope yours will be similar to as follows

%CATALINA_HOME% --- C:\Program Files\Tomcat\apache-tomcat-8.0.28

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.

phpmongodb@kumar:/usr/share/tomcat7/bin$ ./version.sh

Note

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

sudo find / -name "version.sh"

Find out everything about Tomcat7.

sudo find / -name "tomcat7"

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();      
}

If Tomcat is installed as a service, try:

sudo /etc/init.d/tomcat version

Swap out "tomcat" with the actual name of the service.

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

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

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

This will output you sample as below:

enter image description here

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

enter image description here

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

  1. Create JSP page with the below code
  2. Then try to open the JSP via Tomcat in the Browser
  3. 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() %>

You can find out the server information through its status page:

{running-tomcat-url}/manager/status

On that page you can see the version of Java on which your Tomcat runs

Note: I have also pasted this answer on Tomcat6 and JRE7 compatibility issue. Unsupported major.minor version 51.0

Isn't this only when manager is installed? I know the default is to but we don't – Flotation
this is the only one that works on older tomcats lice 3.x ok is says page not found but in the header you get: Server: Tomcat Web Server/x.x.x Final – Abstention

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.

We are running in a Windows environment and I had to find a way to get the Tomcat version outside of the Java environment. Without knowing the version, I could not determine the directories. I finally found the best way was to query the Tomcat service using:

C:\temp>sc query | find /I "tomcat"
SERVICE_NAME: Tomcat6
DISPLAY_NAME: Apache Tomcat 6.0 Tomcat6

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"

In Unix-like environments, I also recommend checking the actual running process command line:

...

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.

To know exact tomcat version alone, just visit vi tomcat/BUILDING.txt

Glennglenna answered 14/6, 2020 at 3:7 Comment(1)
Where does it show the exact Tomcat version in that file? It just says the major and minor version. It does not mention the patch version, not to mention a build number or commit hash. – Seashore

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):

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

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