A novel workflow engine for Web service orchestration, JBPM4WS is proposed in this paper. JBPM4WS is built on JBPM, a well-known workflow engine. We extend the workflow language JPDL, which is adopted by JBPM, to support service invoking. JBPM4WS engine adopts four-layer architecture, and is implemented based on some open-source frameworks, such as Hibernate, CXF and JAXB.

Business Process Execution

Web services based on a service-oriented architecture framework provide a suitable technical foundation for business process management and integration. A business process can be composed of a set of Web services that belong to different companies and interact with each other by sending messages. Web service orchestration languages are defined by standard organizations to describe business processes composed of Web services. A business process can fail for many reasons, such as faulty Web services or mismatching messages. It is important to find out which Web services are responsible for a failed business process because we could penalize these Web services and exclude them from the business process in the future. In this paper, we propose a model-based approach to diagnose the faults in a Web service-composed business process. We convert a Web service orchestration language, more specifically BPEL4WS, into synchronized automata, so that we have a formal description of the topology and variable dependency of the business process. After an exception is thrown, the diagnoser can calculate the business process execution trajectory based on the formal model and the observed evolution of the business process. The faulty Web services are deduced from the variable dependency on the execution trajectory. We demonstrate our diagnosis technique with an example.

The Web service domain is a fast growing and fast changing environment. From a business perspective, the trend over the last few years in the Web services area firmly points toward seamless business logic integration and inter-enterprise collaboration. However, in order to accomplish such goals, both technological and conceptual advances are required. Some already have proven their viability, others still have to be made. Among them, Web service orchestration and choreography are of crucial importance, but still lack a widely agreed on development framework comprising both technological and conceptual aspects. In this paper we try to provide a critical snapshot of current standards for Web service development and particularly we focus on Web service orchestration and choreography. We discuss problems and solutions from a conceptual point of view, exemplify the illustrated ideas by means of real-world technologies and standards and highlight the mutual dependencies that exist among orchestration and choreography of Web services.

The world today is witnessing a growing interest in conducting supply chain business processes electronically. Different supporting technologies are emerging, and many are already available on the market. The adoption of these technologies is hampered by the fact that organizations constantly face new requirements, constraints and demands. Recent research has shown that service-oriented architectures and its supporting technology, Web services, can address many major issues encountered in complex supply chains. However, one of the largely unsolved issues is the orchestration of the variety of Web services in the supply chain. This chapter presents an investigation on orchestration of supply chain business processes using portals and Web service technologies. The portal-based orchestration concepts were carried out in a project for supporting end-to-end supply chain logistics in the United States Department of Defense. A second supply chain study looked at the added value of Web service orchestration.

The Web Service Offerings Infrastructure (WSOI) is a monitoring and management infrastructure for the Web Service Offerings Language (WSOL). It extends Apache Axis, an open-source tool for hosting Web services. We present technical details of several WSOI solutions for monitoring Web Services. To pass management information among management parties, we built WSOI serializer and WSOI deserializer modules converting data between formats of Axis’ MessageContext properties and SOAP headers. To perform different monitoring activities for different WSOL service offerings, we implemented Web Service Offering Descriptor (WSOD) as a complement to Axis’ Web Service Deployment Descriptor (WSDD) component. To represent run-time values of WSOL-related management information, we developed WSOI management information model. All these solutions were verified with a prototype implementation of WSOI 2.0 and validated on case studies.
