Abstract
Web Services Business Process Execution Language
(WS-BPEL) provides the language to specify business
processes that are composed of Web services as well
as exposed as Web services.
In business processes and during service invocation,
errors may occur from latent faults, e.g. partner services
may not be available or not respond within time.[1]
We want to have reliable business processes hence
we need to have reliable web services.
To have reliable web services fault occurrences should
be prevented.
Objective of this paper is to present an architecture which
ensures more reliable composed services. Therefore
we propose an architecture which dynamically detect
and recover failures using software fault tolerance
patterns and mapping them to WS-BPEL .finally a
Business Process is designed To implement attained
proposition.
Keywords: WS-BPEL, Fault Tolerance Pattern, Web Services
