Abstract
We developed WhiteDog System which applies Aspect Oriented Programming (AOP) and supports implementation and running of network-sharing capability. AOP is a methodology of improving software maintainability and extensibility by modularizing similar code fragments that exist in various methods. Applying this AOP methodology, WhiteDog System enables developers to implement network-sharing capability to existing Java application only by GUI operations. In this paper, we will discuss Aspect-Code Generation Method Using GUI in the WhiteDog System.
