The start files use the ie.properties file that the Info*Engine installer generates as the value for the -DpropFile parameter on the Java start command.

The ie.properties file is located in the codebase/WEB-INF directory where Info*Engine is installed and contains a reference to the JSON configuration files that contains the Info*Engine properties. This reference also contains validation information to ensure that the services can access the JSON configuration files.

The installer generates the contents of the ie.properties file based on the values that were entered when Info*Engine was installed. For more information about this file, see the Windchill Installation and Configuration Guide.
