While the rapid and growing diffusion of rich Internet applications (RIAs) with their enhanced interactive, responsive and dynamic behaviour is sharpening the distance between Web applications and desktop applications, at the same time, the maintenance community is experiencing the need for effective analysis approaches for understanding and modelling this behaviour adequately. This paper presents...
Nowadays, there is a large diffusion of open and dynamic cooperative architectures that are based on services (SOA). In general, a customer is not only interested in service functionalities, but also in its quality (i.e. performance, cost, reliability, security and so on). In this scenario, models, techniques and tools supporting the effective selection of the service that provides the better quality...
In the last years, rich Internet applications (RIAs) have emerged as a new generation of Web applications offering greater usability and interactivity than traditional ones. At the same time, RIAs introduce new issues and challenges in all the Web application lifecycle activities. As an example, a key problem with RIAs consists of defining suitable software models for representing them and validating...
In the era of service oriented architectures a relevant research problem consists of turning Web applications into Web services using systematic migration approaches. This paper presents the research results that were obtained by adopting a black-box migration approach based on wrapping to migrate functionalities of existing Web applications to Web services. This approach is based on a migration process...
Warranting the access to Web contents to any citizen, even to people with physical disabilities, is a major concern of many government organizations. Although guidelines for Web developers have been proposed by international organisations (such as the W3C) to make Web site contents accessible, the wider part of today's Web sites are not completely usable by peoples with sight disabilities. In this...
Analysis and classification of Web application user interfaces is a relevant problem in Web maintenance processes. This paper presents an approach for the reliable classification of HTML pages of a dynamic Web application. The approach is based on the assumption that groups of semantically equivalent built pages are characterized by the same key features which can be used for discriminating the pages...
In dynamic cooperative architectures that are based on services (SOA), customers are not only interested in service functionalities, but also in their quality, such as performance, cost, reliability, security and so on. In this scenario, models, techniques and tools supporting the selection of the best service are needed. In this paper, we propose an evaluation framework that includes a flexible quality...
Migration of form based legacy systems towards service-oriented computing is a challenging task, requiring the adaptation of the legacy interface to the interaction paradigm of Web services. In this paper, a wrapping methodology is proposed to make interactive functionalities of legacy systems accessible as Web services. The wrapper that is used for interacting with the legacy system acts as an interpreter...
Migration of form based legacy systems towards service-oriented computing is a challenging task, requiring the adaptation of the legacy interface to the interaction paradigm of Web services. In this paper a flexible wrapper supporting a process for making accessible functionalities of legacy systems as Web services is presented
Presents an approach to migrate legacy systems to object-oriented platforms. The process consists of six sequential phases and encompasses reverse engineering and re-engineering activities. The aim of the reverse engineering phases is to decompose programs into components implementing user interface management and components implementing application domain objects. The identification of objects is...
