Data Web Services on WebSphere Application Server, Part 1: Create and deploy Data Web Services for WebSphere Application Server with IBM Data Studio

Michael Schenker, Software Engineer, IBM

Michael Schenker is a software engineer at IBM's Silicon Valley Laboratory in San Jose, Calif. He joined IBM in 2002 and works in the IBM Data Server Tooling area. His subject of expertise is the Web service enablement of IBM's data servers. He holds a Master's degree in computer sciences from the University of Applied Sciences in Leipzig, Germany.

Summary: IBM® Data Studio, the new unified tooling platform for IBM data servers, provides a feature that allows easy exposure of database operations as Web services, also known as IBM Data Web Services (DWS). This tutorial series will show how Web services created with DWS can be deployed on IBM's WebSphere® Application Server and how WebSphere Application Server enhanced features in terms of security, transaction capabilities and more, can be leveraged to turn your Data Web Service application into a powerful, secure, and reliable enterprise Web service.

Before you start

Learn what to expect from this tutorial, and how to get the most out of it.

About this series

The first product to provide tooling for Data Web Services is IBM Data Studio. With this solution, exposing a database statement as Web service operation is as simple as dragging and dropping an SQL statement or stored procedure into a Web service folder. A Data Web Service can contain one or more operations where each is based on a single stored procedure call or SQL statement. After the Web service has been assembled, runtime artifacts for different application servers can be generated by a click on a button. Data Studio also comes with a testing environment (the Web Service Explorer), which allows you to instantly test the assembled data Web service. The tool conveniently packages the Web service runtime artifacts into a deployable Web Application Archive (war), which can directly be deployed onto an application server instance. Since the Data Web Service runtime artifacts are based on the J2EE standard, it is possible to leverage advanced features provided by the application server, like database connectivity, security, transactions, tracing/logging/monitoring, and more.

Figure 1. Developing and deploying a Data Web Service

IBM's WebSphere Application Server is one of the possible target platforms for Data Web Services. This series of tutorials is dedicated to encouraging you to unleash the full power of Data Web Services in combination with WebSphere Application Server by using some of the enhanced features WebSphere Application Server provides in regards to security, performance, and reliability.

About this tutorial

This first tutorial covers basic topics, such as creating and deploying an IBM Data Web Service on WebSphere, as well as some troubleshooting and monitoring information. Following tutorials in the series will discuss:

Transport-level security
DB2 trusted context
Web service security
Web service atomic transactions

Objectives

Create a basic Data Web Service using IBM Data Studio and deploy it on WebSphere Application Server. Also, see how the service can be tested and WebSphere's tracing/logging feature can be used. All samples in this series are based on the sample service you create here.

Prerequisites

This tutorial is written for database programmers who are familiar with IBM Data Studio and know how to create a database connection, data development project, SQL scripts, or stored procedures, and have completed "IBM Data Studio: Get started with Data Web Services" (developerWorks, November 2007). Basic knowledge of WebSphere Application Server and J2EE is recommended.

System requirements

To run the examples in this tutorial, you need an installation of IBM Data Studio 1.1 (fixpack 2) as well as WebSphere Application Server version 6.0.2 (fixpack 9) or higher or version 6.1.x. Furthermore, you need a DB2 version 8 or 9 installation with the sample database.
