The book opens with a high-level look at component software, introducing the reader to the general concepts involved in using software components, and describing some of their benefits. The first chapter, "Introducing JavaBeans," also covers definitions of such terms as persistence, introspection, event handling, and distributed computing. This chapter provides an explanation of other component models, including CORBA, Visual Basic VBX files, and an amusing critique of Microsoft's entrant into the component technology world, ActiveX. This author certainly makes his views clear on the quality of what's coming out of Redmond.
JavaBeans brings component technology to the Java platform. With the JavaBeans API you can create reuseable, platform-independent components. Using JavaBeans-compliant application builder tools, you can combine these components into applets, applications, or composite components. JavaBean components are known as Beans. JavaBeans is a core JDK1.1 capability. Any JDK1.1-compliant browser or tool implicitly supports JavaBeans. This document is a hands-on guide to learning JavaBeans and the Beans Development Kit (BDK)
Java Beans is the most important new development in Java this year. Beans is the next generation of Java technology that not only adds features the language lacked, but also lets Java programs interoperate with a number of development environments. The initial release includes a bridge for Microsoft's ActiveX/COM; future releases will include bridges for Netscape's Live Connect and IBM's OpenDoc.
Since it's a "component architecture" for Java, Beans can be used in graphical programming environments, like Borland's JBuilder, or IBM's Visual Age for Java. This means that someone can use a graphical tool to connect a lot of Beans together and make an application, without actually writing any Java code - in fact, without doing any programming at all. Graphical development environments let you configure components by specifying aspects of their visual appearance (like the color or label of a button) in addition to the interactions between components.
Bean Books Concepts
The JavaBeans API makes it possible to write component software in the Java programming language. Components are self-contained, reusable software units that can be visually composed into composite components, applets, applications, and servlets using visual
application builder tools. JavaBean components are known as Beans. Components expose their features (for example, public methods and events) to builder tools for visual manipulation. A Bean's features are exposed because feature names adhere to specific design patterns. A "JavaBeans-enabled" builder tool can then examine the Bean's patterns, discern its features, and expose those features for visual manipulation.
Manning The Awesome Power of Java Beans
The Awesome Power of Java Beans provides the details on both. Either way, the power of Java Beans is awesome: once created, your beans run anywhere - ceven masquerading as an ActiveX control. The Awesome Power of Java Beans shows you how to use not only BeanBox, but also such tools as Visual Age Web Runner, JBuilder and PowerJ. And there's a wide-ranging selection of completed and tested beans for you to use in your applications If you're a Java programmer, teacher or student, or if you design software systems using Java Beans, this book will be a valuable resource.
Enterprise JavaBeans: A Primer
The EJB specification and architecture are attempts to make remote, distributed, multi-tier development much easier. It has hoped to do this by introducing a concept known as an Enterprise Java Bean (EJB). The first thing to notice is that EJB, the component, is named the same as EJB, the specification. This is similar to the JavaBeans and Java Bean conundrum. The easiest way to get a grip around this puzzle is to put Java and Beans together when referring to the specifications and separate them when referring to the components. Thus, the remote specification becomes Enterprise JavaBeans and the remote component becomes an Enterprise Java Bean. The local specification becomes JavaBeans and the local component becomes a Java Bean.
Enterprise JavaBeans Books
Enterprise JavaBeans is a cross-platform component architecture for the development and deployment of multi-tier, distributed, scalable, object-oriented Java applications. Enterprise JavaBeans makes it EASY to write business applications as components by providing a set of automatic services to support scalable transactional application server components. Enterprise JavaBeans can be deployed on top of existing transaction processing systems including traditional transaction processing monitors, web servers, database servers, application servers, etc.
