  ServletConfig | A servlet configuration object used by a servlet container to pass information to a servlet during initialization.
  ServletContainerInitializer | ServletContainerInitializers (SCIs) are registered via an entry in the file META-INF/services/javax.servlet.ServletContainerInitializer that must be included in the JAR file that contains the SCI implementation.
  ServletContext | Defines a set of methods that a servlet uses to communicate with its servlet container, for example, to get the MIME type of a file, dispatch requests, or write to a log file.
