Web services using XML standards is a new paradigm in the way B2B collaborations are modeled. It provides a conceptual and architectural foundation which can be implemented using a variety of platforms and products. Today, developers can use the Java 2 Enterprise Edition (J2EE) to build XML-based web services. They can leverage existing J2EE technologies to build a complete and fully interoperable web service that complies with XML standards. Without radical reengineering, and without rebuilding a proven J2EE system, developers can construct complex and powerful web services applications.
A web service is an application that accepts requests from other systems across the Internet or an Intranet, mediated by lightweight, vendor-neutral communications technologies. These communications technologies allow any network-enabled systems to interact. As technologies mature, a web service will encompass additional special functionality geared towards performing multiparty B2B collaboration.
Web services are evolving and beginning to operate in an extremely intelligent and dynamic way. These smart web services will understand the context of each request and produce dynamic results based on each specific situation. The services will adapt their processes based on the user’s identity, preferences, location, and reason for the request. Multiple services will be combined on the fly, collaborating to produce a unique, customized solution. The mechanics of this collaboration will be completely transparent to the consumer, who will experience only the collective benefit delivered by the end result.
The XML standards which a web services system is built upon allows for an implementation-neutral approach to performing business collaborations. There are many possible implementations developers can use, including a variety of products, platforms, and standards. By using a standards-based approach, developers can build a system that provides maximum interoperability for their web services.
This white paper describes the portable Java and XML technology approach for implementing a web services architecture. It explains each of the key web services technologies and how they fit together. You will gain a better understanding of the concepts that underlie a XML web services architecture, and how they fit together with J2EE. We begin with a 30,000-foot birds-eye view of how to build web services using J2EE. This section will give you a high-level understanding of the building blocks of a web services system. We will elaborate on each functional area later in this white paper.
