[JScript] In JScript, you can use the interfaces in the NGWS frameworks, but you cannot define your own.
The application object service is used to get at the application object for the development enviornment. The application object can be used to control the development enviornment. To use the application object service, request it through a call to GetServiceObject. You may cast the resulting object to an extensibility interface or access it as a dispatch interface.
