thanks a lot! I got it working.
A quick follow up
  What's step do I need to take to include this info in documentation ? I think 
it might be useful to others

The list is in the Javadoc:
https://tomcat.apache.org/tomcat-11.0-doc/api/org/apache/catalina/Globals.html

Where else would you like to see it? The where may change which steps are required to update the docs.

Hi everyone!  is it possible to display current version number in a jsp page or 
servlet when using parallel deployment . using some property.
    Currently when building an app war we use git to calculate last revision 
number, store it in a file, use it to name a war accordingly.ex 
Education##15229,  Education##15230 etc.
I know tomcat  already using  something to show version because when checking 
catalina.out for errors it already shows something like
17-Mar-2025 11:15:49.732 SEVERE [https-openssl-apr-8443-exec-73] 
org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for 
servlet  [IndexServlet] with context path [/Education##23459] threw exception  
[org.opensaml.common.SAMLException: Assertion is not conformed with 
notOnOrAfter condition] with root cause

I know if such property exists its probably a tomcat one, not java, since 
parallel deployment is not a java but a tomcat feature
and request. getContextPath() shows only the main part (before ##) - /Education
Ability to display such information in a webpage, would help greatly in 
troubleshooting various app users requests when dealing with multiple version s
Any help is appreciated!
Tomcat version 9.0.64
OS RHEL Linux  6.5
Java version 1.8.202

String webappVersion =
(String)request.gteServletContext().getAttribute("org.apache.catalina.webappVersion");
