The only configuration of Jetty which is available to you is are the properties in the file %IDP_HOME%\jetty-base\start.d\idp.ini, and you should not edit any other file in the jetty-base directory, let alone files in the Jetty installation directory, because you will lose these changes when you perform upgrades.
You must not add any modules to the configuration or do any configuration in this file which is not the editing of the 6 properties provided in the default version of this file.
If you need to edit any file except idp.ini, (or make changes to idp.ini beyond changing the 6 properties) then you are an advanced user and should deploy your own container. You can still use the Windows installer, but should uncheck the Jetty installation box.
