We show how automated support can be provided for identifying refactoring opportunities, e.g., when an application's design should be refactored and which refactoring(s) in particular should be applied. Such support is achieved by using the technique of logic meta programming to detect so-called bad smells and by defining a framework that uses this information to propose adequate refactorings. We report on some initial but promising experiments that were applied using the proposed techniques.

Essential reengineering platform functionality can be made more accessible, and even extended, using Java as a basis for platform development, as follows. The process of software reengineering tool development should be able to enjoy the benefits conferred by "open" enabling technologies. Reengineering tool development and use involves distinctive processes and thus has distinctive requirements of enabling technologies. The earlier dominant "Software Refinery" proprietary reengineering tool development platform is both lacking with respect to required reengineering characteristics and moreover has limited accessibility. However, using Java as basis, the functionality of the proprietary platform can be substantially recreated to achieve open technology goals of adaptability, portability, accessibility and eventually heterogeneity also.

In this paper an approach for automated source-to-source translation from Cobol to Java is presented. The primary goal of this approach is to ensure that the generated code will be maintainable. In some cases this is achieved even by sacrificing complete functional equivalence of the generated code with the original program. We also intensively use encapsulation to hide away difficulties of language conversion process from the maintenance engineer. We discuss results of practical application of this approach on examples taken from the real-life programs.

As the age of software systems increases they tend to deviate from their actual design and architecture. It becomes more and more difficult to manage and maintain such systems. We explore the idea of software clustering for reverse engineering and re-modularization. Clustering together software artifacts provides an automatic technique for discovering high level abstract entities within a system. Previous work on software clustering has identified many areas where further investigation is required. Clustering techniques should be tuned to the type of system they are being applied to. In this paper we explore a new clustering algorithm called the 'combined' algorithm which, as our experiments show, provides more promising results for software clustering than the previously used algorithms. We also analyze the behavior of correlation and distance metrics for binary features.

During software evolution, programmers add new functionalities and release new versions of software. This is complicated work, particularly in large applications, and tools are needed to deal with it. In this paper we introduce a tool named JTracker that helps programmers implement change propagation in Java applications. We conducted a case study of a change in open source application JMeter, in which we used JTracker.

Testing a distributed system is difficult. Good testing depends on both skill and understanding the system under test. We have developed a method to observe the system at the CORBA remote-procedure-call level and then use dynamic-query-based visualization to refine and improve the test cases. The method and accompanying tools have been tested and refined by using them as part of the software support effort for two distributed application, each having about 500 K lines of code. During this time the tools have been adapted to support testing by adding a scripting mechanism that permits the visualization tool to specify test reports. We also added parameter value observation and reporting. Finally, we added an active probing mechanism to induce faults and delays in order to stress the system under test. Our efforts have led to a substantial improvement in system test quality.

Component-based software development (CBSD) is a very promising software engineering technique for improving reuse and maintenance. Nevertheless, there are still some difficulties in practice when reusing, maintaining and evolving components and/or component-based (CB) applications. We review the concepts of version and configuration management and apply them in the context of CBSD. The use of multi-dimensional component libraries, which are software libraries that classify components with respect to different views, is proposed. Next to the libraries, we propose a configuration model for CB applications based on components and connectors. In this way, the libraries not only support component storage and retrieval but also version and configuration management of components and CB applications. Furthermore, it is possible to introduce metrics in the configuration model and libraries allowing us to predict the impact of changes in CB systems.

We present an approach to automatic checking of the correctness of Web applications structure during their lifecycle. The approach adopts the well-established symbolic model checking technique and the associated tool SMV. A formalism allows the designer to describe the model of a Web-based system. Computation Tree Logic (CTL) is adopted as language to define the properties to be verified. The approach has been implemented in a tool to provide automatic support in the design of Web applications. The system embeds the NuSMV model checker to perform verification. Verification is carried out after building the finite state model of a site in the model checker input language. To this purpose the system parses the HTML source code of Web pages, including code for dynamic pages. Properties are expressed using a user friendly interface for Web application developers that automatically translates properties in CTL formulas.

Many Web applications use a mixture of HTML and scripting language code as the front-end to business services. Analogously to traditional applications, redundant code is introduced by copy-and-paste practices. Code duplication is a pathological form of software reuse because of its effects on the maintenance of large software systems. This paper describes how a simple semi-automated approach can be used to identity cloned functions within scripting code of Web applications. The results obtained from applying our approach to three Web applications show that the approach is useful for a fast selection of script function clones, and can be applied to prevent clone spreading or to remove redundant scripting code.

Software services are being promoted as the next big step forward in software engineering. Inevitably, both service vendor and service client programs will require maintenance. We present a service architecture that has been motivated by a long term vision for software as something which is used, not owned. This architecture is used to show how evolution of software can be achieved. It uses the marketplace to drive the process incrementally. We summarise a new fault-tolerant private information retrieval scheme for protecting users' privacy and ensuring service provision even in the presence of intentional/unintentional service provider faults (e.g. malicious failures). An implementation on a realistic distributed database suggests only a modest performance overhead.
