The Web

With the widespread use of the Web, distributed object technologies have been widely adopted to construct network-centric architectures, using XML, Web Services, CORBA, and DCOM. Organizations would like to take advantage of the Web in its various forms of Internet, Intranet and Extranets. This requires organizations to port and integrate their legacy assets to distributed Web-enabled environments, so that the functionality of existing legacy systems can be leveraged without having to rebuild these systems. In this chapter, we provide techniques to re-engineer standalone legacy systems into Web-enabled environments. Specifically, we aim for a framework that allows for the identification of reusable business logic entities in large legacy systems in the form of major legacy components, the migration of these procedural components to an object-oriented design, the specification of interfaces of these identified components, the automatic generation of CORBA wrappers to enable remote access, and finally, the seamless interoperation with Web services via HTTP based on the SOAP messaging mechanism.

The World

In a rapidly changing world, continuous adoption of new practices is crucial for survival; organizations embracing the latest technologies have a competitive edge. Smart organizations readily take on board new organizational forms and practices, those in particular that offer agility and responsiveness. The Internet and the World Wide Web offer a new way of collaboration via Web services, but heterogeneity of different service components make cooperation difficult. This chapter describes a new approach to combine Web services by employing a layered structure, in which composition of a value-added service can be built from individual components, and each service component can have semantically equivalent but syntactically different alternatives.

Active Xml

Active XML (AXML) provides an elegant platform to integrate the power of XML, Web services and Peer to Peer (P2P) paradigms by allowing (active) Web service calls to be embedded within XML documents. In this chapter, the authors present some interesting aspects encountered while investigating a transactional framework for AXML systems. They present an integrated locking protocol for the scenario where the structure of both data and transactions are nested. They show how to construct the undo operations dynamically, and outline an algorithm to compute a correct optimum undo order in the presence of nesting and parallelism. Finally, to overcome the inherent problem of peer disconnection, the authors propose an innovative solution based on ”chaining” the active peers for early detection and recovery from peer disconnection.

Heterogeneous Service

Among traditional users of Web resources, industry has a growing set of smart industrial devices with embedded intelligence. Just like humans, they need online services (i.e., for condition monitoring, remote diagnostics, maintenance, etc.). In this paper, we present one possible implementation framework for such Web services. Such services should be Semantic Web enabled and form a Service Network based on internal and external agents’ platforms, which can host heterogeneous mobile agents and coordinate them to perform needed tasks. The concept of a “mobile service component” assumes not only exchanging queries and service responses, but also delivering and composition of a service provider. Mobile service component carrier (agent) can move to a field device’s local environment (embedded agent platform) and perform its activities locally. Service components improve their performance through online learning and communication with other components. Heterogeneous service components’ discovery is based on semantic P2P search.
