In this paper, we present a mechanism to capture and reestablish the state of Java threads. We achieve this by extracting a thread’s execution state from the application code that is executing in this thread. This thread serialization mechanism is implemented by instrumenting the original application code at the byte code level, without modifying the Java(More)
In this position paper, we present some problems we face in the development of an integrated software application for broadcast planning. Concretely, we’ll discuss customization and authorization. Our current implementation of both issues suffers from heavy cross-cutting and codetangling. Therefore we would like to present these problems at the ECOOP 2000(More)
It is well known that a meta-object protocol (MOP) is a powerful mechanism to control the behavior of an application and to implement non-functional requirements such as fault-tolerance and distributed execution. A key feature of these architectures is the strict separation between the application at the base-level and the non-functional concerns at the(More)
Aspect-oriented-programming (aop) is a promising new approach where the description of a complex system/application is enchanced with various aspects, related to communication properties, distribution, synchronization, etc. All aspects can be described separately and are brought together by using a so-called weaver. Mostly, this is performed at(More)
Building distributed applications is very hard as we not only have to take care of the application semantics but of non functional re quirements such as distributed execution security and reliability as well A component oriented approach can be a powerful technique to master this complexity and to manage the development of such applications In such an(More)
Middleware has emerged as an important architectural component in supporting distributed applications. However conventional middleware technologies are not able to meet the requirements of a wide range of application domains. This position paper describes an approach based on non-functional policies that allows application-specific reconfiguration of ORBs.(More)
