Student Materials

The student kit includes a comprehensive workbook and other necessary materials for this class.

The following software is provided in the student kit:

Module 1: The Need for XML Web ServicesThis module provides students with an understanding of the problem space that XML (Extensible Markup Language) Web services address. The module compares various approaches to implementing distributed applications. Because the Web services in this course are implemented by using Microsoft® ASP.NET and the Microsoft

.NET Framework, alternate options for implementing distributed applications by using the .NET Framework are discussed to better define what kinds of solutions

Web services are appropriate for.

After completing this module, you will be able to explain how XML Web services emerged as a solution to the problems with traditional approaches to designing distributed applications. This includes:

· Describing the evolution of distributed applications.

· Identifying the problems with traditional distributed application architectures and technologies.

· Describing XML Web services and briefly explaining how they address the design problems in traditional distributed applications.

· Listing the alternate options for distributed application development.

· Identifying the kinds of scenarios where XML Web services are an appropriate solution.

Module 2:

XML Web Service Architectures

This module broadly describes the service-oriented architecture, which is a conceptual architecture. Then, the module explains the roles and how XML (Extensible Markup Language) Web service architectures are a type of service-oriented architecture.

After completing this module, you will be able to describe the architecture of an XML Web services-based solution. This includes:

· Identifying how XML Web service architectures are a type of service-oriented architecture.

· Describing the elements of an XML Web service architecture and explaining their roles.

· Describing the XML Web service programming model.

Module 3:

The Underlying Technologies of XML Web ServicesAfter completing this module, you will be able to describe the underlying technologies of XML Web services and explain how to use the .NET Framework to implement XML Web services by using these technologies.

This includes:

· Describing the structures of a

Hypertext Transfer Protocol (HTTP) request and response.

· Issuing HTTP POST and GET requests and processing the responses by using the .NET

Framework.

· Describing data types by using the XML Schema Definition language (XSD).

· Explaining how to control the way a .NET Framework object is serialized to XML.

· Describing the structures of a

Simple Object Access Protocol (SOAP) request and response.

· Issuing a SOAP request and processing the response by using the .NET Framework.

Module 4:

Consuming XML Web ServicesAfter completing this module, you will be able to implement an XML Web service consumer by using Visual Studio .NET.

This includes:

· Explaining the structure of a

Web Service Description Language (WSDL) document.

· Explaining the XML Web services discovery process.

· Locating service contracts by using Disco.exe.

· Generating XML Web service proxies by using Wsdl.exe.

· Implementing an XML Web service consumer by using Visual Studio .NET.

· Invoking an XML Web service synchronously and asynchronously by using an XML Web service proxy.

Module 5:

Implementing a Simple XML Web Service

This module provides students with the skills that are required to implement an XML (Extensible Markup Language) Web service by using Microsoft® Visual Studio® .NET and debug it.

This includes:

· Creating an XML Web service project.

· Implementing XML Web service methods, exposing them, and controlling their behavior.

· Managing state in an

ASP.NET-based XML Web service.

· Debugging XML Web services.

Module 6:

Publishing and Deploying XML Web ServicesThis module teaches students how to deploy and publish XML (Extensible Markup Language) Web services and locate Web services by using the Microsoft Universal Description, Discovery, and

Integration (UDDI) software development kit (SDK). A local development UDDI registry is used in the demonstrations for this module, but the mechanics of publishing and finding Web services is no different on the public UDDI registry nodes.

After completing this module, you will be able to publish and deploy an XML Web service. This includes:

· Explaining the role of UDDI in

XML Web services.

· Publishing an XML Web service in a UDDI registry by using the UDDI SDK.

· Searching a UDDI registry to locate XML Web services by using the UDDI SDK.

· Explaining the various options for publishing an XML Web service on an intranet.

· Explaining some of the options for modifying the default configuration of an XML Web service.

Module 7: Securing XML Web ServicesThis module teaches students how to use the security services of the Microsoft® Windows® operating system, Microsoft Internet Information Services (IIS), and the Microsoft .NET Framework and common language runtime to secure XML (Extensible Markup Language) Web services.

After completing this module, you will be able to secure an XML Web service. This includes:

· Identifying the differences between authentication and authorization.

· Explaining how to use the security mechanisms that Microsoft Internet Information Services (IIS) and

Windows provide for authentication.

· Using SOAP headers for authentication in an XML Web service.

· Using role-based security and code access security for authorization in an XML Web service.

· Encrypting the communication between an XML Web service consumer and an XML Web service.

Module 8:


Designing XML Web ServicesThis module teaches students which design issues to consider when designing real-world XML (Extensible Markup Language)

Web services. The issues discussed are related to data type constraints, performance, reliability, versioning, deployment in Internet Service Provider (ISP) and Application Service Provider (ASP) scenarios, and aggregating Web services. The module also discusses HTML screen scraping as a pseudo Web service.

After completing this module, you will be able to evaluate the trade-offs and issues that are involved in designing a real-world XML Web service. This includes:

· Identifying the restrictions that are imposed on data types by the various XML Web services protocols.

· Explaining how the use of

Application and Session state can affect the performance and scaling of XML Web services.

· Explaining how to use output and data caching to improve XML Web service performance.

· Implementing caching in an XML Web service.

· Explaining how asynchronous XML

Web service methods can improve performance.

· Explaining the need for instrumenting XML Web services.

· Identifying the components of an XML Web service that can be versioned.

· Explaining how to implement a virtual XML Web service by using screen scraping.

· Implementing an XML Web service that uses multiple XML Web services.

· Identifying the trade-offs in the techniques that are used for exposing aggregated XML Web services.

Module 9: Global XML Web Services Architecture

This module teaches students how to use the security services of the Microsoft® Windows® operating system, Microsoft Internet Information Services (IIS), and the Microsoft .NET Framework and common language runtime to secure XML (Extensible Markup Language) Web services.

After completing this module, you will be able to:

· Describe limitations inherent to the specifications with which today's XML Web services are built.

· Describe the design principles and specifications of Global XML Web services Architecture (GXA).

· Describe XML Web service application scenarios made possible by Web Services Routing Protocol (WS-Routing) and Web Services Referral Protocol (WS-Referral).

· Explain how to use Web ServicesSecurity Language (WS-Security) and Web Services License Language (WS-License) to perform authentication and authorization for XML Web services.

· Design XML Web services that anticipate and can leverage the features that GXA will offer when released
