Replication is a technique which is widely used for speeding up access to passive objects. Consistency requirements of distributed object oriented programming languages, however, limit the scope of object replication to coarse grain objects or objects which are modiied infrequently. This is due to the fact that the overhead for global synchronization and preserving replica consistency often out...

In today’s systems, applications are composed from various components that may be located on different machines. The components (acting as servers) may have to collaborate in order to service a client request. More specifically, a client request to one component may trigger a request to another component. To ensure fault-tolerance components are generally replicated. Replicated components lead ...

In this paper we present a source transformation-based framework to support uniform testing and model checking of implicit-invocation software systems. The framework includes a new domain-specific programming language, the Implicit-Invocation Language (IIL), explicitly designed for directly expressing implicit-invocation software systems, and a set of formal rule-based source transformation too...

The ability to dynamically bind to Web services at runtime is becoming increasingly important as the era of Service-Oriented Computing (SOC) emerges. With SOC selection and invocation of Web service partners will occur in software at run-time, rather than by software developers at design and compile time. Unfortunately, the marketplace has yet to yield a predominate applications programming int...

ly, a~l implicit invocation mechanism can be modelled as a collection of components, each of which has an interface that specifies a set of methods and a set of events. As is traditionally the case, the methods define operations that other components can explicitly invoke. The events, however, define actions that the component promises to announce to other components in the system. The implicit...

Cooperative and collaborative groupware work en vironments like work ow management systems or con ferencing systems often face the problem to inte grate existing application programs to perform spe ci c tasks Although some basic form of application integration is available virtually none of these systems has provisions to support the invocation of multi user applications such as tele conferenci...

This paper presents a proposal for incorporating a group communication paradigm into an object-based environment. Group communication is an interaction involving an arbitrary number of participants. Its application simpli es speci cation and implementation of complex systems. Object-oriented programming can signi cantly pro t from the addition of a group mechanism. Our proposed mechanism, Multi...

A natural way to benefit from distribution is via asynchronous invocations to methods or services. Upon invocation, a request is enqueued at the destination side and the caller can continue its execution. But a question remains: “what if one wants to manipulate the result of an asynchronous invocation?” First-class futures provide a transparent and easy-to-program answer: a future acts as the p...

Subprograms like procedures and methods can be invoked explicitly or implicitly; in implicit invocation, an event implicitly causes the invocation of subprograms that are registered an interest in the event. Mixing these two styles is common in programming and often unavoidable in developing such software as GUI applications and event-based control systems. However, it isn’t also uncommon for t...

Platform independent dynamic analysis has been shown to be an important technique for performance analysis and workload characterization of programs that run on the Java Virtual Machine. In this paper we explore how this methodology can me used to study method invocation. We identify differences in program behaviour and propose a metric to predict dynamic compilation efficiency. Key-Words: Java...
