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.

Component-based software development is the next step after object-oriented programmingthatpromisesto reducecomplexityandimprovereusability.These advantages have also been identi?ed by the industry, and consequently, over the past years, a large number of component-based techniques and processes have been adopted in many of these organizations. A visible result of this is the number ofcomponentmodels thathavebeendevelopedandstandardized.These models de?ne how individual software components interact with each other and simplify the design process of software systems by allowing developers to choose from previously existing components. The development of component models is a ?rst step in the right direction, but there are many challenges that cannot be solved by the development of a new component model alone. Such challengesare the adaptation of components, and their development and veri?cation. Software Composition is the premiere workshop to advance the research in component-based software engineering and its related ?elds. SC 2005 was the fourth workshop in this series. As in previous years, SC 2005 was organized as an event co-located with the ETAPS conference. This year’s program consisted of a keynote on the revival of dynamic l- guages given by Prof. Oscar Nierstrasz and 13 technical paper presentations (9 full and 4 short papers). The technical papers were carefully selected from a total of 41 submitted papers. Each paper was thoroughly peer reviewed by at leastthreemembers oftheprogramcommittee andconsensusonacceptancewas achieved by means of an electronic PC discussion. This LNCS volume contains the revised versions of the papers presented at SC 2005.

The book constitutes the refereed proceedings of the 11th International Conference on Software Composition, SC 2012, held in Prague, Czech Republic, in May/June 2012, co-located with TOOLS 2012 Federated Conferences. The 12 revised full papers were carefully reviewed and selected from 42 submissions for inclusion in the book. The papers reflect all current research in software composition and are organized in topical sections on software composition in specification languages; context-aware and dynamic composition; composition in software development; and applications of software composition.

nd The 2 WorkshoponEmergingWeb ServicesTechnology(WEWST'07) wasco- th catedwiththe5 EuropeanConferenceonWebServices(ECOWS'07)whichtook place in November 2007 in Halle (Saale),Germany. WEWST focuses on research contributions advancing the state of the art in Web Services technologies. The main goal of the WEWST workshop is to serve as a forum for providing early exposure and much needed feedback to grow and establish original and emerging ideas within the Web Services community. The wide variety of tools,techniques and technologicalsolutions presentedin WEWST shareone common feature:they advance the currentWeb Servicesresearchin new directions by introducing new, sometimes controversial, ideas into the ?eld. As such, WEWST is the natural extension to the main ECOWS conference. Asitcanbeseenfromtheworkshopprogram,thespectrumofresearchtopics related to such emergent technologies includes: the challenge of adopting RESTful Web Services and Resource Oriented Architectures; Dynamic Web Service D- covery, Selection and Composition; extensions to the standard Business Process Execution Language; the management of composite Web Services; the delivery of well de?ned Quality of Service guarantees; the performance evaluation of Web Services.These are all still among the hot topics in Web Services research since no satisfactory solution has been found yet.
