<Insert Picture Here> Web Service Landscape

Web Services : What is it? Points to description Describes Service Finds Service Invokes with XML Messages SOAP/REST UDDI Registry Points to service WSDL Web Service (JEE, SOA, PL/SQL, .NET,C/C++, Legacy …) Web Service Client (JEE,SOA,.NET, PL/SQL …)

Where is Web Service today? Standards : still evolving JAX-* WS-* Adoption Everybody understands what it is Ubiquitously adopted and deployed Popular for connecting platforms and applications Starting to go beyond basics What are the pain points? Security Performance Complexity Interoperability Contention points SOAP vs. REST …

Feature : Dual Programming Model Service Endpoint WSDL Description WSDL<->Java Mapping Dispatch Container Service Client Protocol (SOAP/REST) Server Side Runtime System JAX-WS/RPC API Client side Runtime System Stub Transport Tie JAX-WS/RPC API

JAX-WS vs JAX-RPC? SOAP 1.2 vs SOAP 1.1 JAXB (data mapping model) MTOM (Message Transmission Optimization Mechanism) XML/HTTP - WSDL 1.1 specification defined an HTTP binding, which is a means by which you can send XML messages over HTTP without SOAP. JAX-RPC ignored the HTTP binding. JAX-WS adds support for it. WS-I's Basic Profiles JAX-RPC supports WS-I's Basic Profile (BP) version 1.0. JAX-WS supports BP 1.1. JAX-RPC maps to Java 1.4. JAX-WS maps to Java 5.0. EJB 3.0 vs EJB 2.1 The handler model (SAAJ 1.3 specification)

Feature : REST JAX-WS HTTPBinding JAX-RS (JSR-311) @WebServiceProvider( targetNamespace="http://example.org", serviceName = "HelloRS") @BindingType(value = HTTPBinding.HTTP_BINDING) public class HelloRS implements Provider<Source> { public Source invoke(Source source) { return createSource(“Hello World”); } } @Path("/helloworld") public class HelloRS { @GET @Produces("text/plain") public String getClichedMessage() { return "Hello World"; } }

Feature : Database Web Services XML Parser JAX-RPC Servlet Decoding Encoding Oracle WebLogic Web Service SOAP SOAP SOAP Libraries Publisher Generated Artifacts SQL/Query SQL/DML XML PL/SQL JDBC JSP

Feature : Asynchronous Web Service Synchronous MEP Common use cases Request/response MEP over HTTP Short-running operations Real-time processing Pain points Blocking Indefinite waiting Timeout Asynchronous MEP Common use cases Two one-way MEP over HTTP Long-running operations Delayed or batch processing Benefits Better suit real-world business model Provide richer messaging patterns beyond request/reply Thread/JMS-based responder

Feature : Stateful Web Service Client to remain in a conversation over consecutive requests/responses Useful for building shopping cart type applications using web services Container to control message dispatching to service endpoint “ Pinning” service endpoint instance Storing attributes in HTTP Session client server GetShoppingCart (new session) ShoppingCart + SessionID(#1) addItem + SessionID(#1) GetShoppingCart(new session) ShoppingCart + SessionID(#2) Response + SessionID(#1)
