icon Element

  The icon element specifies the location within the Web Application for a small and large image used to represent the Web Application in a GUI tool. (The servlet element also has an element called the icon element, used to supply an icon to represent a servlet in a GUI tool.)

  This element is not currently used by WebLogic Server.

  The following table describes the elements you can define within an icon element.
