What's New in SOAP 1.2. SOAP, Web Services Marc Hadley Sun Microsystems Bagshot United Kingdom marc.hadley@sun.com Marc Hadley is a Staff Engineer in the XML Technology Centre at Sun Microsystems.
He currently represents Sun on the W3C XML Protocol Working Group where he is co-editor of the SOAP 1.2 specification. Prior to joining Sun Microsystems, Marc worked for Chrystal Software as a principle consultant and chief engineer developing content management and web delivery systems based on XML. SOAP is currently the subject of a standardisation effort at the W3C. Web 服务编程技巧与窍门: WSDL 文件导入. 导入（Import）语句很简单，对吗？
差不多每个程序或接口语言都用到它。 当你阅读这篇技巧时，可能早已了解了关于导入的所有知识。 那么，为什么要阅读这篇关于 Web 服务描述语言（Web Services Description Language，WSDL）文件导入的技巧呢？ 首先，import 语句有两种类型：XSD 导入和 WDSL 导入。 其次，这两种导入语句各自的特点不完全相同。 Import 与 include 在深入描述 import 语句之前，让我们先来比较一下 import 和 include 之间的区别。 回页首 XSD 导入 让我们来查看基本 XSD 导入，如清单 1 中用红色突出显示的部分所示。 清单 1. 从清单 1 的范例中显而易见导入的主要目的是为了导入命名空间。 当您从一个文件导入命名空间时，将看见 XSD 导入语句中的 schemaLocation 属性，但这是一个可选属性。 现在，查看清单 1中用蓝色突出显示的 import 语句。 必须确保您在 import 语句中使用的命名空间与您所导入模式的 targetNamespace 相同。 清单2和3源于清单 1。 Web 服务提示和技巧：避免匿名类型. 简介 我们经常看到由匿名类型编写的 Web 服务 XML 架构。
此架构的作者在构建这类架构时也不太可能会意识到匿名类型可能会导致潜在问题。 本文将总结使用匿名类型可能会引起的问题，希望读者能够避免它们。 什么是匿名类型？ 匿名 XML 类型是 xsd:element 中嵌入的类型。 清单 1. 名为 “person” 的元素中的 complexType 本身没有名称，因此它是匿名的。 Usage of document/literal wrapped pattern in WSDL design. Introduction While defining a highly interoperable Web Service in a WSDL using document/literal style of messaging, a “pattern” which is known as wrapped-document/literal, is followed across service providers.
This pattern takes the advantage of best features of both the RPC/Literal as well as Document/Literal messaging in WSDL by: Inserting the SEI (Service Endpoint Interface) Operation name in SOAP Message – Feature of RPC/literal.Complete definition of the SOAP Message in the W3C XML Schema – Feature of Document/Literal. A WSDL describes a web service by defining its interface, the operations on that interface, their binding to the transport protocol, and the network address they are available at. A WSDL binding describes how a web service is bound to a messaging protocol, that is, what is the format or structure of the Messages being exchanged with a Service, and the transport protocol over which this Message will be sent.

Take any integration project and you have multiple applications talking over multiple transports on multiple platforms.
As you can imagine, in large enterprise applications this can get complex very fast. Much of the complexity stems from two issues: 1. dealing with the specifics of applications and transports, and 2. coming up with good solutions to integration problems. Making your applications speak transports and APIs is relatively easy on its own. Ignoring the mechanics of how to connect with multiple transports and APIs, we can focus on the high level design of how applications interact. Apache Camel was created with the intention of addressing these two issues. What is Camel? Apache Camel is an open source Java framework that focuses on making integration easier and more accessible to developers. . • concrete implementations of all the widely used EIPs • connectivity to a great variety of transports and APIs Figure 1 shows how these three items actually map to Camel concepts.
. • Java DSL. Maven cxf-codegen-plugin (WSDL to Java) CXF includes a Maven plugin which can generate java artifacts from WSDL.
Here is a simple example: In this example we're running the wsdl2java goal in the generate-sources phase. By running mvn generate-sources, CXF will generate artifacts in the <sourceRoot> directory that you specify. Each <wsdlOption> element corresponds to a WSDL that you're generated artifacts for. The WSDL location is specified via the <wsdl> option. The following example shows some customization options. See this blog entry for a full service and client example that uses the cxf-codegen-plugin. Example 1: Passing in a JAX-WS Binding file In this example we're specifying that we want CXF to use our JAX-WS binding file.
Example 2: Specify the data binding In this example we're specifying that we want CXF to use our data binding jibx. How I Explained REST to My Wife.
Which style of WSDL should I use? Introduction A WSDL document describes a web service.
A WSDL binding describes how the service is bound to a messaging protocol, particularly the SOAP messaging protocol. A WSDL SOAP binding can be either a Remote Procedure Call (RPC) style binding or a document style binding. A SOAP binding can also have an encoded use or a literal use. This gives you four style/use models: RPC/encodedRPC/literalDocument/encodedDocument/literal Add to this collection a pattern which is commonly called the document/literal wrapped pattern and you have five binding styles to choose from when creating a WSDL file.
Before I go any further, let me clear up some confusion that many of us have stumbled over. Likewise, the terms encoded and literal are only meaningful for the WSDL-to-SOAP mapping, though, at least here, the traditional meanings of the words make a bit more sense. Listing 1.
