BPEL is emerging as an open-standards language for
Web service composition. However, its procedural style
can lead to inflexible and tangled code for managing a
crosscutting aspect — synchronization constraints that
define permissible sequences of execution for activities in
a process. In this paper, we present DSCWeaver, a tool
that enables a synchronization-aspect extension to BPEL.
It uses DSCL, a synchronization expression language, to
specify constraints. DSCL has the desirable features of
declarative syntax, fine granularity, and validation
support. A designer can use DSCL to describe and
validate the synchronization behavior and rely on
DSCWeaver to generate BPEL code. We demonstrate the
advantages of our approach in a service deployment
process and evaluate its performance using two metrics:
Lines of Code (LoC) and Places to Visit (PtV). Evaluation
results show that our approach can effectively reduce
development effort of process designers while providing
performance competitive to un-woven BPEL code.
