using IBM WebSphere Studio and JavaBeans, with a clear and understandable explanation of XML and database programming In the simplest way possible, you’ll learn reusable concepts, not just product Along the way, you’ll learn the basics of how to develop Java applets and applications, as well as more advanced topics, such as using relational databases and eXtensible Markup Language (XML) documents to store your application data By the end of the tour, you’ll be able to use IBM WebSphere Studio to build your own applications, and you’ll understand why JavaBeans are so useful for application programming This book assumes you have some basic knowledge of the Java programming language, but you certainly don’t need to be an expert to follow the tour You do need to be running one of the Windows operating systems, and as long as you’re comfortable with Windows, the Internet, and Web browsers, you’re ready to learn Java Experts will benefit from the tour, because it will teach you many of the IBM WebSphere Studio features that will let you build your Java applications easier and faster This book uses the “show and tell” approach If you flip through the pages, you’ll notice that they are loaded with pictures showing you how your applications should look at each step along the way When you complete this book, you will know how to: Use IBM WebSphere Studio and JavaBeans to easily create applications Code in eXtensible Markup Language (XML) Use databases with your applications Build applications more efficiently and productively Create applets Use Swing components and layout managers About the Authors Colette Vurrus recently retired from IBM, after spending more than 20 years in a variety of programming and project management jobs Her most recent assignment was project manager for the IBM alphaBeans project, working with the “Beans Around the World” team She also coauthored a previous book, VisualAge for Java for Non-Programmers, and a corresponding Web-based tutorial series Stephanie Parkin is an information architect for the IBM WebSphere Developer Domain Web site In her career at IBM she has been managing editor of the WebSphere and VisualAge Developer Domains, and has created and edited documents for various programming languages, including VisualAge for Basic She also was the Editor-in-Chief of the WebSphere Developer Technical Journal Stephanie also coauthored the previous book and tutorial series, and has published an article on Designing Beans in Java Developer’s Journal Building Applications with WebSphere Studio and JavaBeans—A

colleagues at Software House Technology (now Exigen Latvia), in Riga, Latvia Tatjana Lukovnikova, Pavels Nikolajevs, Juris Krikis, and Tatjana Apine wrote the initial VisualAge for Java tutorials upon which this book is based Also, a huge thanks to Dave Pullin for the initial idea and the determination to get this knowledge in the hands of users And thanks to the scores of developers who worked on the "JavaBeans Around the World" Project Their beans provided the core technology that let us build the applications in this book Second, we'd like to thank our technical reviewers at IBM: Joe Winchester reviewed the entire book and gave excellent feedback, and Jim Mann also provided valuable comments Thanks to Ernest Mah and Dr Gili Mendel for answering product questions and to Lynn Jonas, Mark Edwards, John Botsford, Nak Paik, and Jeff Turnham for getting us early access to product drivers Thanks to Merrikay Lee for her editing expertise Finally, a warm thanks to Tara Woodman for a very smooth book-publishing process and equipment to help develop the book Introduction This book takes you on a guided tour to building applications with the WebSphere Studio Visual Editor for Java and JavaBeans Along the way, you'll learn the basics of how to develop Java applets and applications, as well as more advanced topics such as using relational databases and eXtensible Markup Language (XML) documents to store your application data By the end of the tour you'll be able to use WebSphere Studio to build your own applications and you'll understand why JavaBeans are so useful for application programming If you're new to Java and Java development environments, that's OK This book assumes you have some basic knowledge of the Java programming language, but you certainly don't need to be an expert to follow the tour You do need to be running one of the Windows operating systems, and as long as you're comfortable with Windows, the Internet, and Web browsers, you're ready to learn Java If you are already familiar with Java and Java development environments, that's OK, too You'll still benefit from going through the tour, because it will teach you many of the WebSphere Studio features that will let you build your Java applications easier and faster This book uses the "show and tell" approach If you flip through the pages, you'll notice that they are loaded with pictures showing how your applications should look at each step along the way In addition, we've included two CDs that contain all the tools you'll need to follow along with the lessons Why Java? Java is considered the language of the Internet It combines two important advances in computer science: object orientation and platform independence Object orientation means that the programming language models real-world components and behavior You organize your programs into objects with certain properties and define the activities that the objects can perform Complex behavior is hidden in the implementation of the object, letting you just connect the object to other objects Secondly, Java is platform-independent, which means that you can create programs on a Windows machine and be confident that the program will work in any environment that Java runs in In the past few years the use of Java has exploded It has expanded well beyond its original main purpose of providing dynamic Web pages, to a full server-side programming language It enables the development of complex Internet functionality, such as querying legacy databases, enabling business-to-business Web commerce, and providing interactive Web communications Because it's based on open standards, all Java programs use a common API This means that you can reuse other Java components and easily snap them into your programs Visual Editor for Java WebSphere Studio Site Developer 5.0 is the development tool that you'll use during the guided tour As you'll see, WebSphere Studio is a fullfunction integrated development environment that contains everything you need to create, test, and maintain your Java applications The Visual Editor for Java, new with WebSphere Studio 5.0, makes development of Java applications even easier and faster—you just drag and drop the elements you want to use for your application and customize them to set the properties you want, and it generates the underlying code for you Appendix B: Java Basics Figure B.1: Cars are a class of objects Figure B.2: A single class can have multiple constructors Figure B.3: Running the program in WebSphere Studio Figure B.4: Source code for a simple Java program List of Tables Chapter 5: Using Layout Managers Table 5-1: Properties for additional SettingPanel beans Chapter 8: Advanced Applet Development Table 8-1: NavigationPanel applet parameters Chapter 9: Working With Databases Table 9-1: Column data List of Sidebars Chapter 1: Creating Your First Applet What's a JAR file?
