Error 'The REST Servlet is not configured in your environment' after upgrading to 5.3.10.120

In that case, that’s how I would reset the lucee server. This will wipe any setting configured through the Lucee Admin (web/server), also schedules and the admin password. But as you said, you didn’t setup anything in the Lucee admin, I’d reset your Lucee to the latest update as follows…

  1. backup everything so you can easily switch back if something goes totally wrong.
  2. Download the latest stable Lucee.jar from https://download.lucee.org
  3. Stop the Tomcat/Lucee service in the Windows Service Manager
  4. Copy the downloaded Lucee.jar to c:\path-to-your-lucee-installation\tomcat\lib\ext\ (you will see another lucee.jar there. You can simply rename that one to lucee.old or similar but you MUST rename the extension or delete the file, otherwise Tomcat will load those too)
  5. Delete the directory lucee-server at c:\path-to-your-lucee-installation\tomcat\lucee-server
  6. Delete any existing WEB-INF folder (these are the webcontexts) within existing webroots, e.g. c:\inetpup\sitefolder\web-inf
  7. Restart the Tomcat/Lucee service in the Windows Service Manager

Wait for Tomcat to create the lucee-server directory and files, and also the web-inf web-contexts.

You may need to reset the password of your server admin. To do that, open a text editor, eriter your password there and save that file as password.txt to
c:\path-to-your-lucee-installation\tomcat\lucee-server\context\password.txt. When opening the Lucee Administrator you will be prompted to import the password.txt file. Just click on the import button. Then login and if everyone goes well you should be greeted with the newest Lucee version.

I hope I didn’t mention some path location incorrectly, coz’ Im writing these instruction from my mobile while my wife is driving :wink:
