description binds the abstract interface description to a concrete network address, communication protocol, and concrete data structures. The concrete implementation description is used to bind to the service and invoke its various operations (methods). In this chapter, we provide an overview of the WSDL document by considering the simple example of a weather service. Then we describe in more detail the general structure of the WSDL document, including the parts of a WSDL document that correspond to the abstract interface and the parts that correspond to the concrete implementation. We also provide a description of the logical relationships among the different elements of the WSDL document as well as provide a description of some of the SOAP extensibility elements.

In addition to the WSDL description of a service and the SOAP message format, a central place is needed where the service provider can advertise the services they offer and the service consumers can find the services they require. Such a central place is called a service registry. The Universal Description, Discovery, and Integration (UDDI) specification defines a standard way for the registering, deregistering, and looking up of Web Services. First, a service provider registers a service with the UDDI Registry. Then the service provider looks up the service in the UDDI registry. Lastly, the service consumer binds to the service provider and uses the service. In this chapter, we describe in detail the basic data model of a UDDI registry. This basic model consists of five entities: businessEntity, businessService, bindingTemplate, publisherAssertion, and tModel. A businessEntity is used to store information about a service provider, such as its name and address. Nontechnical information about a service is stored in the businessService structure. Technical information related to a service and its endpoint is stored in the bindingTemplate entity. Perhaps the most important entity is the tModel, which serves the dual purpose of providing the technical fingerprint of a service and an abstract namespace. In this chapter, you will learn how to store categorization and identification information in a tModel using categoryBags and identifierBags. In addition, you will learn how to author or partition a WSDL document related to a service so that it can be easily referenced in a bindingTemplate and in a tModel. Finally, we briefly discuss the two APIs offered by the UDDI specification for publishing and inquiring about an exiting service. core subject of Part V of the book, which is how to develop new Web Services. We describe two approaches for the development of new Web Services in the Java/J2EE environment. The first approach is the topdown approach, which is the recommended approach. In this approach,

a WSDL document is either constructed or acquired first. Then automated tools are used to create skeleton code both for the server side and the client side. The server code is then completed according to the given requirements. The second approach is the bottom-up approach of developing Web Services. In the bottom-up approach, either a Java class or Enterprise Java Bean (EJB) is developed first and then automated tools are used to expose the class or EJB as a Web Service. The automated tools also generate the required WSDL document, which is used to generate the service clients through the use of automated tools. Because all the messages in the Web Services are exchanged through SOAP messages, we start this chapter with a discussion of the two major choices for a SOAP engine, which is simply a framework for constructing SOAP processors such as clients, servers, and gateways.

16: Integration Through Service Composition (BPEL) Web Services clients construction is suitable if the interaction of the client application with the service provider is isolated and simple. Such activities are simple and stateless. However, in many scenarios the interaction of the services clients with the service providers is not so simple. Such is the case of business processes. A business process is a collection of related, structured activities. Such complex structured activities require a stateful environment for the invocation of a chain of Web Services. BPEL (Business Process Execution Language) is a language to describe such long running, stateful interactions. We describe BPEL in some detail in 16. In 16, we start by providing a brief overview of BPEL. The overview is followed by a detailed description of the various elements and structure of BPEL. Then we describe a practical example of a business process to demonstrate how various elements are used together. The last section of this chapter summarizes the contents of the chapter.

This section contains the references and the glossary of terms used in the book. Conclusion In this chapter we described the rationale for writing this book by pointing out some of the gaps in the existing books on the market and describing how this book covers those gaps. We also identified the people who would be interested in the subject of this book, which would include practically anyone who is interested in enterprise integration through the use of services. We pointed out that no prior knowledge of either SOA or applications integration is required. This chapter ends with brief summaries of each of the 16 chapters of this book.
