有人会认为可以在注册中心找到服务提供者的元数据后,再把服务消费者与服务提供者直接绑定起来,但是这是错误的。
One would think that we can make the Service consumer directly bind to a Service provider after finding its metadata in the registry, but that would be a mistake.

对这个挑战的回答是基于注册中心的“延迟绑定”。
The answer to this challenge is the use of registry-based “late binding”.

假定uddi注册中心找到了一个匹配的键值,您将用第一个键值,然后查找与该服务相关的绑定模板,如清单18所示。

有时候,在连接到合作伙伴的系统时,您需要一个联合注册中心服务来定位服务及其绑定详细信息。
Sometimes while connecting with a partner's systems, you need to have a federated registry service to be able to locate the service and its binding details.
服务使用者然后在UDDI注册中心中查找所需的服务,当它发现需要的服务时,使用者将直接与提供者绑定来使用该服务。
A service consumer then looks up the required service in the UDDI registry, and, when it finds the required service, the consumer directly binds with the provider to use the service.
这个注册中心浏览器使用JAXRAPI 并通过使用被作为参考实现的一部分提供的UDDI绑定获得一个到注册中心服务器的连接。
This registry browser makes use of the JAXR API and obtains a connection to the registry server using the UDDI binding that is provided as part of the reference implementation.
在此情况下,服务定义在使用者开发期间可用,注册中心的使用仅限于服务端点地址和动态绑定的运行时解析。
In this case services definitions are available during consumer development time, and registry usage is limited to the run time resolution of the services endpoint addresses and dynamic binding.

Please note that, of the reference PUREXML instances, PUREXML1 doesn't bind to any schema and PUREXML2 binds to the registered schema as in Listing 1.
这个类可以通过服务注册中心提供的接口,端点地址和绑定信息创建一个服务代理。
This class allows creating a service proxy based on the interface and endpoint address and binding, which are built using information provided by the registry service.

实际上,很多SOA专业人员都已经将服务注册中心作为用于进行后期绑定和动态路由的机制加以引入了。
In reality many SOA practitioners have been introducing service registry as a mechanism for late binding and dynamic routing.
这不仅可以让我们改变端点地址和绑定类型(很多注册中心的实现都有这些功能)外,也可以通过统一集中的注册中心对绑定参数进行细微调整。
This allows not only to change endpoint addresses and binding types (features found in many registry implementations), but also to tweak binding parameters using a centralized registry.
凡在应用程序启动时,都对照注册表来验证角色绑定。
Whenever an application starts, the role bindings are verified against the registry.
除了WCF支持的WebServices绑定,这个服务注册中心还支持本地(语言)绑定。

从uddi注册中心检索服务绑定。
在通过使用注册中心发现服务之后,对于特定的服务有三种绑定类别
There are three categories of binding to a specific service after the service has been discovered through the use of the registry
在此场景的商业实现中,客户端可能需要查询注册中心(如websphereServiceRegistry和Repository)才能将传出请求以动态方式绑定到端点。
In a commercial implementation of this scenario, the client would likely query a registry, like the WebSphere Service registry and Repository, to dynamically bind the outgoing request to an endpoint.
确保客户机使用的是服务的当前绑定信息的唯一办法就是在每个GetQuote操作调用前重新查询UDDI注册中心。
The only way to ensure that the client is using the current binding information for the service would be to requery the UDDI registry before every individual invocation of the GetQuote operation.
Web服务请求者在UDDI注册中心查找Web服务,绑定到Web服务,然后调用它。
A web service requester finds the web service in the UDDI registry, binds to the web service, and invokes it.
表单提交后,这些输入参数就会被提交到到登录命令uri,这个URI被绑定到LogonCmd接口,存放在WebSphereCommerce命令注册表中。
On submission of the form, the input parameters are submitted to the Logon command URI, which is bound to the LogonCmd interface in the WebSphere Commerce command Registry.
人员解析插件绑定到特定的人员存储库,如WebSphereApplicationServer用户注册表或LDAP目录。
A staff resolution plug-in is bound to a specific staff repository, like the WebSphere Application Server user registry or an LDAP directory.
另一方面,十几个甚至上百个网站都推出了新的服务,旨在帮用户绑定他们所选择的,假定还未被注册的用户名,同时收取一定的费用。
Moreover, new services have emergedthat will help you—for a sometimes-substantial fee—nail down the username ofyour choice, assuming it isn’t already taken, at dozens or even hundreds ofsites.
