How do I?...
Conceptual overviews
Documentation Introduction: Web services Presentations IBM Education Assistant offers:

developerWorks offers:
- Tutorial 4 - Web services
The objective of this tutorial is to provide you with an understanding of the new standard JAX-RPC programming model to develop SOAP based Web service clients and endpoints. The endpoint is described by using WSDL. The zip file comes with all sample code required to run this tutorial.
Samples
The Samples Gallery offers:
- WebSphere Bank
Using the WebSphere Bank online bank, customers can open accounts, get account balances, and transfer funds between accounts. The WebSphere Bank application uses Web services, Java Message Service (JMS) API, container-managed persistence (CMP), container-managed relationships (CMR), stateless session beans, Message-Driven Beans (MDB), JSP pages, and servlets.
- Greenhouse by WebSphere
Using the Greenhouse by WebSphere online supplier, customers can open accounts, select items and amounts to order, and check their order status. The Greenhouse by WebSphere application uses Web services, the Java message service (JMS) API, scheduler, asynchronous beans, container-managed persistence (CMP), container-managed relationships (CMR), stateless session beans, message-driven beans (MDB), Java server pages (JSP)s, and the struts framework.
- Adventure Builder
The Adventure Builder customer Web site resides on the Web tier and is designed using a Web application architecture. This Web site communicates to the order processing backend module using Web services interactions. Adventure Builder, a basic Web site travel application built on the J2EE 1.4 platform, is a simple shopping application.
The customer can browse and select from a catalog of products, in this case vacation packages, assemble or build an entire vacation from different components, principally lodging and activities. The parts of a particular vacation package are determined by user responses given on a sequence of forms. We can maintain vacation package options in a virtual shopping cart, perform sign on and sign off procedures, create user accounts, and purchase a trip package, sending a purchase order to the order fulfillment system. The Adventure Builder application uses several J2EE 1.4 technologies.
- Development Strategies - Address Book
The Address Book sample illustrates accessing multiple Web Services in one application.
- Migration - Stock Quote
The Stock Quote sample illustrates migration of a stock quote client from SOAP to Java API for XML-based RPC (JAX-RPC). WebSphere supports Web Services for J2EE (JSR 109) which builds on a client-programming model on JAX-RPC.
