Overview<\/h2>\n\n\n\n

Occasionally, Clients contact our support tech team wanting to know what the current version of Tomcat that we support. As I write this document (Mar 2022), we support up to Tomcat 9. While Tomcat 9 is the major version, there are many minor versions of Tomcat 9 that are available to upgrade to.<\/p>\n\n\n\n

Clients wishing to upgrade their current Tomcat 9 version (ex. 9.0.8) to Tomcat 9.0.102 should follow the instructions listed below.<\/p>\n\n\n\n

Note:<\/strong> These instructions are only available for customers currently utilizing Tomcat 9. Customers who wish to migrate from Tomcat 7 should first follow these<\/a> instructions. Once completed, return to the instructions below.<\/p>\n\n\n\n

These instructions assume you are not using the AJP connector. If you are, please contact mrc Technical support.<\/p>\n\n\n\n

Steps<\/h2>\n\n\n\n

Before beginning, check the current version of your Tomcat. The easiest way to check would be to open any m-Power run-time application. In the URL, replace the “s” that is located at the end of your application with an “x”. This will cause a 404 to appear.<\/p>\n\n\n\n

  1. Find the appropriate version from the Apache Tomcat 9 Website<\/a>.<\/li>\n\n\n\n
  2. Download the zip from the Core distribution.<\/li>\n\n\n\n
  3. Extract these files to c:\\temp\\TC9.<\/li>\n\n\n\n
  4. Stop Tomcat (Development).<\/li>\n\n\n\n
  5. Make a copy of development\\m-power\\tomcat\\ to tomcat_old. In the event the upgrade fails, having a backup will make reverting much easier.<\/li>\n\n\n\n
  6. Copy over the c:\\temp\\TC9\\apache-tomcat-9.x.xxx\\bin\\bootstrap.jar file to development\\m-power\\tomcat\\bin. Overwrite the existing file.<\/li>\n\n\n\n
  7. On your m-Power server, remove any files that begin with ecj* from development\\m-power\\tomcat\\lib<\/li>\n\n\n\n
  8. Copy over all jar files in c:\\temp\\TC9\\apache-tomcat-9.x.xxx\\lib to development\\m-power\\tomcat\\lib. Overwrite all files.<\/li>\n\n\n\n
  9. On your m-Power server, edit the development\\m-power\\tomcat\\conf\\server.xml. Find the AJP listener line and comment it out.
    Note:<\/em>The default AJP listener looks like this: <Connector port=”8009″ protocol=”AJP\/1.3″ redirectPort=”8443″ \/><\/li>\n\n\n\n
  10. On your m-Power server, edit the development\\m-power\\tomcat\\conf\\context.xml. Add the following directly before the final <\/Context><\/code>:
    <Resources cachingAllowed=\"false\"\/><\/code><\/li>\n\n\n\n
  11. Start Tomcat and verify everything is working to your liking. If so, repeat the process above for your production instance(s). You can also remove the tomcat_old folder we created earlier when you feel comfortable doing so.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
