distributed application. Currently such crosscutting concerns are frequently realized on top …

Abstract Design of distributed architectures for content-based publish-subscribe (pub-sub)
service networks has been a challenging problem. To best support the highly dynamic and …

We present an overview of JTL (the Java Tools Language, pronounced" Gee-tel"), a novel
language for querying JAVA [8] programs. JTL was designed to serve the development of …

Detailed knowledge about implemented concerns in the source code is crucial for the cost-

Next-generation middleware must support complex compositions that involve dependencies
between multiple components residing in different contexts and locations in the network. In …

Dependency injection is a hot topic among industrial developers using component

We study AOP in the context of business programming with Cobol. We face the following
questions: What are join points in Cobol programs? What is advice? Does classic Cobol …

The modularity of aspect-oriented programming (AOP) has been a controversial issue. To

In this paper we present an approach for oblivious composition of Web user interfaces,
particularly for volatile functionality. Our approach, which is inspired on well-known …

In this paper, we identify three problems with current component middleware. First, the
implementation of services is usually not modularized, making it hard to adapt the platform to …
