Tomcat: How to find out running Tomcat version?

Solution 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.

Server version: Apache Tomcat/7.0.30
Server built:   May 23 2013 02:54:10
Server number:  7.0.30.0
OS Name:        Linux
OS Version:     3.13.0-36-generic
Architecture:   amd64
JVM Version:    1.7.0_65-b32
JVM Vendor:     Oracle Corporation

Solution 2:

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=".

Solution 3:

execute the script in your tomcat/bin directory:

sh tomcat/bin/version.sh

Server version: Apache Tomcat/7.0.42
Server built:   Jul 2 2013 08:57:41
Server number:  7.0.42.0
OS Name:        Linux
OS Version:     2.6.32-042stab084.26
Architecture:   amd64
JVM Version:    1.7.0_21-b11
JVM Vendor:     Oracle Corporation

Solution 4:

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

Solution 5:

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 assume that your Tomcat is running on port 8080
