This special issue explores several approaches to accomplishing the notion =

of web services discovery and composition. This issue is similar to recent =

venues that explore implementation issues in the form of a competition=20
(Blake, 2005; WS-Challenge, 2006). This guest editorial preface discusses=20
the general aspects of service discovery and composition that are=20

As the emergence of service-oriented architecture provides a major boost=20

increasing. However, when there are a large number of Web services=20

to ?compose? multiple Web services to fulfill the goal. This article=20
presents an AI planning-based Web service composition algorithm named Web=20
Services Planner (WSPR). The efficiency and effectiveness of WSPR is=20
evaluated using two publicly available test sets=ADEEE05 and ICEBE05. In=20
addition to analyzing the two test sets, the authors also suggest several=20

?A Dynamic Two-Phase Commit Protocol for Adaptive Composite Services?
=20
Weihai Yu, University of Troms=F8, Norway
Calton Pu, Georgia Institute of Technology, USA
=20
Next-generation applications based on Web services impose additional=20
requirements on the use of coordination protocols with various=20
optimizations, such as the two-phase commit protocol (2PC). This article=20
analyzes the well-known 2PC optimizations ?presumed commit? and ?presumed=20
abort,? and presents an improved 2PC that is suitable for=20
Web-service-based applications. More specifically, the protocol allows=20
every individual service provider to dynamically choose the most=20
appropriate presumption for any distributed transaction. This new=20
capability is especially useful when a composite Web service is=20
integrating component services that make different presumptions in their=20
commit protocols. The protocol does not introduce extra overhead to the=20
previous 2PC variants in terms of number of messages and log records, and=20
it is easy to understand and realize. The simulation shows that the choice =

of appropriate presumption has significant influence on system=20
performance, and that in some heterogeneous settings, combining different=20
presumptions in individual transactions outperforms adopting only one=20
single presumption.
