How to tell what version of Apache Tomcat is being used by NetBackup or OpsCenter

Description

The version of Apache Tomcat being used by NetBackup or OpsCenter can be determined by two methods.

Method 1 - Current release notes

Open the text file RELEASE-NOTES in the Apache Tomcat directory location as appropriate for the application.

There will be an entry towards the top of the RELEASE-NOTES file that states the version number.  This entry looks similar to the following example:
                     Apache Tomcat Version 8.5.39
                  Release Notes

In NetBackup

Windows: <install_path>\NetBackup\wmc\webserver\RELEASE-NOTES

Linux: /usr/openv/wmc/webserver/RELEASE-NOTES

In OpsCenter

Windows: <install_path>\Symantec\OpsCenter\gui\webserver\RELEASE-NOTES

Linux: /opt/SYMCOpsCenterGUI/webserver/RELEASE-NOTES

Method 2 - Use Java to Query Catalina

The java command may be used to query the catalina.jar file, which will show the metadata associated with the installed libraries. Specifically, it will show the ServerInfo information.

An example output from a Windows NetBackup 8.2 master server:
