By default, new m-Power installations are shipped with the 7.0.24 version of Tomcat 7. As Tomcat is a software made by Apache and not mrc, users who would like to upgrade their current version of Tomcat to the latest version may follow these steps below.
1) Download the zip files here.
2) Make a copy of your current lib folder in /m-power/tomcat
3) Extract the downloaded zip files and copy the new lib folder over to the current m-Power lib folder in /m-power/tomcat.
4) Once done, restart Tomcat.
