A novel approach for run time web service exception handling

Abstract

Currently web services are being widely and extensively used in the business world mainly because they offer reusable application-components and due to their support in solving the interoperability problem by providing different applications a way to link their data. The current consumer needs are mainly converged towards leveraging an efficient method of determining if the exceptions occurring during the runtime execution of the web services can be handled. Moreover, the identification of manageable exceptions also comes into picture when consideri ng the manageability aspect of a web service stimulating an increased value of reliability of the service. In this paper, we propose an innovative model for focusing upon and verifying the manageability of a web service. Runtime management has been given utmost significance as a potential strategy to handle runtime exceptions increases the adaptability of services to exceptional circumstances. Thus a novel architecture for exception handling has been proposed which affords facilities for explicit reference to the cause, location, priority and dependency of the various runtime exceptions in contrast to the traditional pattern of throwing only the exception message.
