TRAP/J v2.1: An improvement for Transparent Adaptation

With the advent of mobile, pervasive, and grid computing, software systems must be designed to dynamically adapt to changes that might occur in their runtime environments. Certainly, careful system design and modeling are key factors for systems to be complete. However, as technology changes and new forms of technology continue to emerge, predetermining all possible scenarios in which a system may be running is nothing short of impossible. These issues can be addressed with a tool called TRAP/J (Transparent Reflective Aspect Oriented Programming in Java. However, the first implementation of this tool performs poorly on demanding applications, severely lacked usability, and provided very limited support for adaptation. In this paper, we will be addressing various issues in the first implementation of TRAP/J and we have developed a new version, TRAP/J v2.1, which is aimed at providing better performance and usability over the original
