Define the application and give it a name by setting the This.name variable in the Application.cfc initialization section, before the method definitions. By using a specific application name, you define a set of pages as part of the same logical application.
ColdFusion supports unnamed applications, which are useful for ColdFusion applications that must interoperate with JSP tags and servlets. Consider creating an unnamed application only if your ColdFusion pages must share Application or Session scope data with existing JSP pages and servlets. You cannot have more than one unnamed application on a server instance. For more information on using unnamed applications, see Sharing data between ColdFusion pages and JSP pages or servlets.
