To enforce consistency and reliability of web services composite at run-time, solving exception is to ensure the transaction atomicity anomalies，it is an effective method. This paper proposes a novel mechanism based on directed graph to addressing the problem of exception handling in web services composite. According to execution dependencies and compensation dependencies among tasks in business processes, adopt the approach of directed graph to set up functional model, when exceptions are handled with forward or backward-recovery methods during execution of business processes, the approach can guarantee compensation achieving, and also gives consideration to the problem that there are no compensation services or the cost to achieve compensation,it is too expensive. Simulations prove that when the approach can efficiently guarantee the consistency and reliability of composite services at run-time.

This paper proposes an exception handling mechanism based on Adaptation Planning Graph for service-based business processes. A three-layer representation model of service-based business process is introduced firstly. And then, Logic Model of Service-based Business Process and Adaptation Planning Graph are introduced to enforce reliability of composite Web Services at run-time. Simulations prove that this approach can efficiently guarantee the reliability of composite services at run-time.

BPEL-based composition of Web services has become one important part of business processes, but because of the dynamic and complexity of network, it easily raises various exceptions during the execution. In order to address various exceptions may exist in execution of composite Web services process effectively; this paper proposes an effective exception handling model of composite Web services in combination of the autonomic management theories and techniques in the field of autonomic computing. This model incorporates the autonomic management element of autonomic computing to monitor the execution of composite services and to compensate or restore the business process of the composite services according to the specified policy when an exception occurs. The model enhances the exception handling autonomy while reducing the complexity of exception handling of composite services.

Nowadays, Web services are emerging as a major technology for achieving automated interactions between distributed and heterogeneous applications (Benatallah, Sheng, & Dumas, 2003). Various technologies are behind this achievement including WSDL, UDDI, and SOAP1. (Curbera, Duftler, Khalaf et. al. 2002) These technologies aim at supporting the definition of services2, their advertisement, and their binding for triggering purposes. The advantages of Web services have already been demonstrated and highlight their capacity to be composed into high-level business process (Benatallah et al., 2003). Usually, composite services (CS) denote business processes and are meant to be offered to users who have needs to satisfy.

Service Oriented Architecture (SOA) introduced the web services as distributed computing components that can be independently deployed and invoked by other services or software to provide simple or complex tasks. In this paper we propose a novel approach to solve the problem of the business processes execution engine web service selection and services composition in the Service Oriented Architecture (SOA) related to the Synchronous mode.  The paper provides a mechanism to improve the web services selection and service composition, using dynamic web services and service composition classification and Simulated Annealing (SA) to satisfy services' requirements expressed as the Service Level Agreement (SLA). The results show that the proposed approach enhanced the services composition by increasing the availability and decreasing the response time to the service composite.

Service-Oriented Computing (SOC), a main trend in software engineering, promotes the construction of applications based on the notion of services. SOC has recently attracted a great deal of attention from researchers, and has been comprehensively adopted by industry. However, service composition enabling the aggregation of existing services into composite services still imposes a great challenge to service-oriented technology. Web service composition requires component Web services to be available in request, to behave correctly in operation, and to be replaceable flexibly in failure. Although availability of Web services plays a crucial role in building robust SOC-based applications, it has been largely neglected, especially for service composition. In this chapter, we propose a service composition framework that integrates a set of composition-based service discovery mechanisms, a user-oriented service delivery approach, as well as a service management mechanism for composite services.

The Cost

Small and Medium Enterprises (SMEs) are the most important drivers in many economies. Due to their flexibility and willingness to innovate they can stand up to larger industry players. However, SMEs – as every other company – need to further reduce costs and optimize their business in order to stay competitive. Larger enterprises utilize ERP systems and other IT support for reducing costs and time in their business processes. SMEs lack behind because the introduction and maintenance of ERP systems are too expensive, the return on investment is achieved too late and the associated financial risks are too high. However, SMEs would like to have IT support for their business. The research behind the Federated ERP System (FERP) addresses the problems SMEs face with conventional ERP systems and offers reasonable and scalable IT support. This is done by decomposing the whole business logic of the ERP system into Web services, which are linked at run-time. The service composition is realized by a workflow system that is also responsible for creating and managing the user interfaces and the data-flow. By integrating only the Web services that are needed (possibly from third parties) the cost is reduced and the functionality can be scaled to the actual needs. However, not only a technical solution is needed but also the development process must be tailored towards SMEs. Small companies cannot afford highlyskilled staff and often do not have defined business processes.

The integration of large systems remains problematic in spite of advances in composite services approaches, such as Web services and business process technologies. The next challenge in integration is composite process-personalization (CPP), which involves addressing the needs of the interaction worker. An interaction worker participates and drives business processes. As these workers increasingly perform their work from mobile devices, CPP becomes an important area of mobile research. In this chapter, an agent-based approach to composite services development is introduced, addressing the lack of CPP in integration. A case study is used to demonstrate the steps in the agent-based approach.
