For Java servlets, how is the application name specified?

The application name for Java servlets is specified in the web.xml file using the display-name element. This file is part of the Java EE (Enterprise Edition) specification and is used to configure various aspects of a web application, including servlets, filters, listeners, and more.

In the web.xml configuration, the display-name element allows you to provide a user-friendly name for the application that can help with identification, especially in environments such as application servers where multiple applications might be deployed. This name can appear in server management consoles or logging outputs, making it easier to recognize the specific application in use.

Other options do not align with the standard methods of specifying application names for Java servlets. System properties or command line arguments may be used for various configuration settings but are not specifically related to defining the application name in the context of servlets. The application.yml file is more commonly associated with Spring Boot applications rather than conventional servlet configurations.
