Towards Fault Handling in B2b Collaboration Using Orchestration Based Web Services Composition

Recently, Web Services Composition is receiving significant amount of interest as an important strategy to allow Business-toBusiness collaboration. The current Web Services composition solutions are inherently unreliable, so how to deliver reliable Web Services composition over unreliable web services is a significant and challenging problem. In this paper, we propose a framework for reliable method of fault handling in B2B collaboration using Orchestration based Web services composition (WSBPEL). The Fault handling method is to be applied during the web services composition process in order to perform some measure of exception handling. We developed a separate Fault handling module that could identify the faults and also that could handle the faults during the composition process. We also devised the various Exception handling strategies that could provides the series of action processing steps to execute alternative web service when a particular web service fails. Further more, we designed an implementation module to implement the reliable fault handling logic that could be associated with WSBPEL
