Dynamically adaptable distributed applications need to be composed in an expressive and modular fashion due to the complexity of these applications. This paper discusses the shortcomings of recent approaches to achieve this goal, in particular the aspect-oriented programming approaches. It addresses the requirements for consistent and modular dynamic adaptation of applications, while improving their modularity. Then, the Remote Role-Playing (RRP) concept is presented as a new promising programming technique, which aims at employing the separation of crosscutting concerns in distributed applications dynamically at runtime in a modular and consistent manner with high degree of expressivity. The paper introduces the DOT/J framework which implements the RRP. The feasibility of the DOT/J approach and its advantage over other approaches is demonstrated through a case study.
