The Java programming language provides both reflection and remote method invocation: reflection allows a program to inspect itself and its runtime environment, remote method invocation allows methods to be invoked transparently across a network. Unfortunately, the standard Java implementations of reflection and remote method invoca-tion are incompatible: programmers cannot reflect on a remote a...

One approach to solve the end to end (E2E) quality of services (QoS) problem of multimedia services delivery over multi-domain IP heterogeneous network infrastructures in a scaleable manner is the establishment of long term QoS enabled aggregated pipes. To allow dynamism, the actual service invocation of these pipes can be made as a separate action from the pipes subscription. This paper propos...

Java is commonly considered the ideal language for implementing software for the In-ternet. A closer look, however, reveals that distributed programming is poorly supported in Java. This is because the very design of the language rules out distribution{transparent remote invocation. It is shown that Sun's technology for distributed Java programming, RMI, makes things worse by allowing two diier...

Most bindings to CORBA are based on the construction of stubs, which translate a language call into a CORBA invocation. This paper shows an alternative way to build a binding, using the reflexive facilities of an interpreted language. Like other CORBA bindings, this binding allows a program to manipulate CORBA objects in the same way it manipulates local objects. Unlike conventional bindings, h...

During execution, activity durations may vary from those predicted in the generated schedule. In this article we study (re) scheduling invocation, execution during rescheduling, and flexible to enable a high level of responsiveness uncertainty duration. We discuss these methods theoretically context an embedded scheduler practically limited CPU with nonzero runtime intended for planetary rover....

In this paper we present a new infrastructure for building distributed applications that communicate through remote objects. The objects are available by the use of the Java RMI, enhanced by replication. Shared objects may be arbitrary complex with references to other objects allowing nested invocations. The replication process may be controlled and tuned by careful design of shared objects gra...

Java’s Remote Method Invocation is an example of a synchronous communication mechanism with a well defined protocol. Many software systems require more flexibility in their communication mechanisms, including asynchronous communication and delayed referencing of objects (Futures). This paper introduces a novel mechanism allowing Java remote objects to use extended communication protocols withou...

A software interceptor is a procedure or object that interposes itself between an invoking client and an invoked server software entity. Procedural interceptors can redirect procedure invocations to alternative procedures that are selected dynamically at run time. Procedural interceptors are useful for program profiling, tracing, dynamic delegation of operation implementation, and interactive d...

72 Published by the IEEE Computer Society 1089-7801/09/$25.00 © 2009 IEEE IEEE INTERNET COMPUTING S oftware systems built on top of serviceoriented architectures (SOAs)1 use a triangle of three operations — publish, !nd, and bind — to decouple roles participating in the system. Publish and !nd put requirements on the service registry and the interface de!nition language. To publish services, an...

ColdFusion's initial appeal was to "webmasters" who wanted to make their sites more dynamic. It succeeded admirably. But just as the term, webmaster, is an anachronism, the call for more dynamic websites has been succeeded by the need for true web applications. As these applications become more involved and more ambitious in scope, ColdFusion developers find that a thorough knowledge of tags an...
