You can also use GUI to config this file.

The default config only support jsp feature,you can add more features to support.

Open your liberty installation folder <Liberty_Install_dir>\usr\servers\server_name,you can see below structure.The application configuration files will  be default put under apps folder.Also you can directly put the war files into the dropins folder,when start the liberty server,it will scan these two folder and automatic start the application from these two folders.
