Section 1. About this tutorial

Purpose of this tutorial

This tutorial shows J2EE developers how to use the IBM ETTK (Emerging

Technologies Toolkit) to make any Enterprise JavaBean (EJB) component into a Web

service that will run on any application server.

Do you currently use EJB technology? Have you ever wondered how to expose an EJB

component as a Web service no matter what your application server is? This tutorial

shows how to use the ETTK to convert a local and remote EJB component into a Web

service. I will use a subcomponent of the ETTK called Axis, a SOAP client

implementation originally hosted by the Apache Software Foundation.

The ETTK implements the Web services architecture and provides a set of tools to

create, locate and invoke Web services. It includes the following tools:

UDDI4J API allows developers to perform save, delete, find, and get operations

against a UDDI registry.

UDDI4J WSDL API allows developers to perform publish, unpublish, and find

operations against a UDDI registry.

WSDL4J allows developers to programmatically read and work with WSDL

documents.

WSDLdoc allows developers to automatically generate documentation from WSDL

files similar to JavaDoc.

WSIL4J allows developers to programmatically read and work with WSIL documents.

Axis RC1 allows a developer to generate Web services WSDL definitions from Java

code and generate Java proxy code from a WSDL definition. Axis is also the

transport engine for Web services.

Sample services including Accounting, Contract, Metering, Service Desk etc.

Demos and tutorials to illustrate key Web service concepts.

Privacy Policy Authorization Director (PAD) Web service allows privacy policy control

access to personal information.

And much more...

The primary focus of this tutorial is developing EJB based Web services with Axis. Axis

provides support for turning EJB components into Web services and is included with

the ETTK.

What do I need to know for this tutorial?
