About This Handbook This handbook is intended to complement the instructor-led presentation of sap bc416 course, and serve as a source of reference. It is not suitable for self-study. Typographic Conventions American English is the standard used in this handbook.
The following typographic conventions are sap bc416 used. Type Style Example text Description Words or characters that appear on the screen. These include field names, screen titles, pushbuttons as well as menu names, paths, and options. Sap bc416 used for cross-references to other documentation both internal sap bc416 this documentation and external in other locations, such as SAPNet.
Screen output. This includes file and directory names and their paths, messages, names of variables and parameters, and passages of the source text of a program. Exact user entry. These are words and characters that you enter in the system exactly as they appear in the documentation. Variable user entry. Pointed brackets indicate that you replace these words and characters with appropriate entries.
Web Service Security Target Audience This course is intended for the following audiences: Unit Objectives After completing this unit, you will be able to: Introduction to Web Services ESA and Web Services Overview BC Lesson: Lesson Objectives After completing this lesson, you will be able to: What is a Web service?
Business sap bc416 are divided into a certain number of process steps. You 2 reasons by trey songz assign one or more functions to each of these steps and an executing software component to each of these functions. If you look at a typical heterogeneous sap bc416 landscape in an organization, it is quickly apparent that the necessary functions in a business process are not all implemented using the same technology and the same components.
In particular, the integration of an ever increasing number of business partners further complicates this problem. Sap bc416 modern software infrastructure must therefore be capable of integrating functions that are implemented on very different software components into an efficient global process. Internet technology already provides the basis for communicating with distributed services. Superimposed onto this simple, globally accepted communication standard, XML eXtensible Markup Language provides the basis for defining additional necessary standards.
It is only when sap bc416 turn away from proprietary definitions and move towards generally accepted standards sap bc416 there can be any guarantee of smoothly integrating all of the functions and partners involved in the process.
The result is Web services. Introduction to Web Services Figure 1: Web Service Definition A Web service is an independent, modularized, self-describing application function or service.
Based sap bc416 XML standards, these application functions can be described, made available, located, transformed, or called via standard Internet protocols. Each Web service therefore encapsulates a piece of functionality sap bc416 can be used, for example, to forward a price query to a provider, check the availability of an item in an enterprise resource planning system, locate a telephone number, or even to run credit card checks, convert currencies, or implement payroll functionality.
In principle, any programming language can be used to implement this service. When publishing a service, the service provider transmits information about itself and a description of the service it is offering and transfers this to the service registry. In addition to other data, sap bc416 also provides information on calling the Web service, for example.
The service registry therefore provides a description of the Web service only. This description forms an abstraction layer and is therefore not dependent on the corresponding implementation. The Web service itself is hosted by the service provider. The user of a Web service is called a service requester. A service requester can be, for example, someone who locates a Web service using a Web browser and then uses this service.
In most cases however, the service requester is an application that accesses the Web service. Overview BC the necessary information for this from the service description, which is in turn stored in the service registry. However, if the application recognizes the provider and the call details, it can obviously use the Web service without having to access the service registry.
Figure 2: If Web services are to be called from any application, a standardized description is required. The Web service provider must also be able to make its offer publicly available as easily as possible. See http: The specification provides a detailed description of how to locate and register services. Examples include: SOAP provides a more straightforward standard that allows you to call Web services in decentralized, sap bc416 landscapes.
SOAP defines what is known as an Envelope. This Envelope contains the actual XML-based message and additional information on how the message is to be processed, for example. A further series of conventions was also adopted for describing the technical constraints. Figure 3: XML documents are increasingly used to support the exchange of business documents and messages, and thereby strengthen cooperation between companies.
This protocol is used to call Web services in distributed system landscapes. A SOAP brunella gori e-pointer has a header sap bc416 information concerning security and transaction and a body content of the message.
WSDL documents are broken down into the names of the services, messages that are exchanged to use these services, links to specific transport protocols, and addresses at which a Web service is available. UDDI is different from other registry services insofar as it does not store documents or specifications, but only references them. Credit Card Check Web services have a variety of different applications: The following figure shows how a Web service can be used to integrate a credit card check into a process landscape.
Figure 4: This means that SAP users can provide Web sap bc416 with a minimum of effort. The Web services framework consists of the following components: There are two procedures used sap bc416 preparing Web services within the development environment: The Web service creation wizard, which involves just a few mouse clicks, or a step-by-step procedure. Wizards sap bc416 predefined profiles with predefined settings for securing Web services or for the transport protocol being used.
The second procedure involves the step-by-step configuration of a Web service from scratch. This involves more work compared to using the wizard, but it also allows you to implement individual customizations.
Overview BC Figure 5: Users have the option of customizing this standard interface to their own requirements. For example, they sap bc416 rename and hide parameters, sap bc416 provide default values. This means that based on the original, implemented interface, any number of views can be defined to provide individually customized, platform-independent interfaces for the Web service clients.
It is also capable of calling Web services as a Web service client. The development environment provides support for this. A client proxy must be generated before a Web service can be implemented in an application. Every standard-compliant WSDL description can be used as an entry for proxy generation.
