For customers in the m-Power community running Apache Tomcat 10 with m-Power, a common question mrc gets is how to update their Tomcat 10.
For instance, clients running Tomcat 10.1.40 can update to the latest version (at the time of writing this, 10.1.52) in order to meet security compliance or just to stay current with Apache Tomcat’s latest updates.
This tech blog post will outline how to update Tomcat 10 to a later version, assuming a standard m-Power installation.
While these steps will assume Tomcat 10 is utilized on Windows server, the update process is similar for Linux installations.
1. Backup current Tomcat 10
Prior to updating, backup of the existing version of Tomcat 10 by making a copy of /tomcat directory in ..../m-power/tomcat.
Name it tomcat_backup or similar.
2. Download new version of Tomcat 10
Download the latest version of Tomcat 10 from the Apache website here. Select the proper distribution that fits your environment. For example, m-Power customers using a 64-bit windows server will need to download the 64-bit Windows zip.
Extract the download to an easily accessible directory on the m-Power server, such as C:/temp.
3. Updating Tomcat 10 directories
Stop the Tomcat 10 service.
Then copy the /lib and /bin directories in C:/Temp/apache-tomcat-10.x.xx to the existing ..../m-power/tomcat directory, choosing to overwrite all existing files.
Optional – copy the RELASE-NOTES file as well, which contains the version number of Tomcat as well as links to the change log.
4. Restart Tomcat and verify version
Start the Tomcat service and verify the m-Power applications can be accessed as normal.
There are several ways to verify the current version of Tomcat has been updated:
Option 1. Navigate to your m-power server address.
https://MPOWER_SERVER_ADDRESSIf utilizing the default Tomcat landing page, this will display a “Welcome to Tomcat!” page with the version number.
Option 2. Open in a text editor the tc10xxx-stderr.yyyy-MM-dd.log file in .../m-power/tomcat/logs and look for this line that contains the version information near the top of the file:
20-Mar-2026 13:08:47.777 INFO [main] org.apache.catalina.startup.VersionLoggerListener.log Server version name: Apache Tomcat/10.1.52
