Service Consumer Figure 11-8 Composite message exchange pattern SOAP processing model At the application level, a typical Web service interaction occurs between a service consumer and a service provider, optionally with a lookup to a service registry. At the infrastructure level, additional intermediary SOAP nodes might be involved in the interaction (Figure 11-9). Initial Sender Figure 11-9 SOAP processing model Composite Service Producer Application-Level Communication actor = "security" actor = "logger" = SOAP Node 370 WebSphere Application Server V7.0: Concepts, Planning, and Design 1 3 2 Node role = SOAP Message Path Service 1 Producer Service 3 Producer Service 2 Producer Requestor Provider Intermediary A Intermediary B Ultimate Receiver
These intermediary nodes might handle quality of service and infrastructure functions that are non-application specific. Examples include message logging, routing, prioritization, and security. In general, intermediaries should not alter the meaning of the message body. A typical situation where you need to use intermediary SOAP nodes is where you have an existing internal Web service implementation within your enterprise that you now want to expose externally. There might be new requirements associated with requests originating from outside of your organization, such as additional interoperability requirements, increased security requirements, auditability of requests, or contractual service-level agreements. These requirements can be implemented using an intermediary SOAP node, or a Web service gateway. Web service gateways A Web service gateway is a middleware component that bridges the gap between Internet and intranet environments during Web service invocations. It can be used internally to provide the SOAP node functions as described previously. It can also be used at the network boundary of the organization. Regardless of where it is placed, it can provide some or all of the following functions: ► Automatic publishing of WSDL files to an external UDDI or WSIL registry ► Automatic protocol/transport mappings ► Security functions ► Mediation of message structure ► Proxy server for Web service communications through a firewall ► Auditing of SOAP messages ► Operational management and reporting of published interfaces ► Web service threat detection and defense 11.5 Support for Web services in WebSphere Application Server WebSphere Application Server V7.0 implements the Java EE 5 and Java SE 6 standards, and therefore it provides support for SOAP and for XML. The support for Web services in WebSphere Application Server can also be combined with the capabilities of an Enterprise Service Bus (ESB) product such as WebSphere Enterprise Service Bus or WebSphere Message Broker. This section addresses how WebSphere Application Server V7.0 supports a Web services architecture. Chapter 11. Web services 371
