Selected revised papers from the peer-reviewed 2007 European Conference on Web Services (ECOWS) and the peer-reviewed 2007 Workshop on Emerging Web Services Technology (WEWST). Keynote by Prof. Schahram Dustdar Includes supplementary material: sn. pub/extras
Component-based software development represents a significant evolution beyond object-oriented programming, aiming to reduce complexity and enhance reusability. The industry has recognized these benefits, leading to the adoption of numerous component-based techniques and processes across various organizations. This shift has resulted in the development and standardization of multiple component models, which define interactions between software components and streamline the design process by enabling developers to utilize pre-existing components. However, the creation of component models is just the initial step; numerous challenges remain, including component adaptation, development, and verification. The Software Composition workshop is a leading forum for advancing research in component-based software engineering and related fields. SC 2005 marked the fourth event in this series, held alongside the ETAPS conference. The program featured a keynote by Prof. Oscar Nierstrasz on the revival of dynamic languages and included 13 technical presentations (9 full and 4 short papers) selected from 41 submissions. Each paper underwent rigorous peer review by at least three program committee members, with acceptance reached through an electronic discussion. This LNCS volume presents the revised versions of the papers from SC 2005.
Middleware provides an integration framework for multiple and potentially - verse computing platforms. It allows developers to engineer distributed appli- tions more easily, providing abstractions and primitives to handle distribution and coordination. Middlewareisconstantlyfacingnewchallenges. Today’sadvancesincomp- ing, including development of pervasive applications, exacerbates the diversity problem, introducing variations not only in terms of performance, but also in terms of environments and device characteristics. Software engineers are the- fore challenged both in the area of the development of new and scalable m- dleware systems, where open, heterogeneous, component-based platforms should provide richer functionality and services, and in the area of application devel- ment, where tools to simplify the use of middleware solutions are necessary. Software Engineering and Middleware is the premier workshop for the - search and practice community of software engineering working in both areas to presentanddiscussnewideasinthis? eld. SEM2004wasthefourthinternational workshop on software engineering and middleware of the EDO/SEM workshop series. Previous workshops of this series were successfully held in 2002, 2000 and 1999. Most of the proceedings have been published by Springer in the Lecture Notes in Computer Science series.
