Professional Ajax discusses the range of request brokers (including the hidden frame technique, iframes, and XMLHttp) and explains when one should be used over another. You will also learn different Ajax techniques and patterns for executing client-server communication on your web site and in web applications. By the end of the book, you will have gained the practical knowledge necessary to implement your own Ajax solutions. In addition to a full chapter case study showing how to combine the book's Ajax techniques into an AjaxMail application, Professional Ajax uses many other examples to build hands-on Ajax experience. Some of the other examples include:

• web site widgets for a news ticker, weather information, web search, and site search
• preloading pages in online articles
• incremental form validation
• using Google Web APIs in Ajax
• creating an autosuggest text box

The tour of the EJB component model presented here centers on several beans created and tested for a travel reservation system in a fictitious cruise ship company. The samples are just right in scale, large enough to test out key concepts in design and deployment, but small enough to be comprehensible, even to those who are not Java experts. The author pays close attention to the real-world issues of deployment with EJBs (as well as the differences among the vendor application servers that run them).

While there are enough details in Java syntax for designing both entity and session beans for the developer, sections on design here will please those who manage projects without delving much into code. Later, the author shows various ways to design entity and session beans. (For instance, entity beans can allow their bean containers to handle the details of connecting to a database, or they can do it themselves. This book demonstrates both approaches.) When it comes to session beans (which "wire" together entity beans to do real work), the author's introduction to managing state and transactions is also a standout. Tips for performance and reusability close out the book.

In all, Enterprise JavaBeans provides an engaging tour of one of the most promising component technologies. It's technically astute, but thoroughly approachable too, and can serve the needs of any manager or Java developer considering EJBs for future projects. --Richard Dragan

Topics covered: Enterprise JavaBeans (EJBs) basics, distributed architectures, Component Transaction Monitors (CTMs), bean-containers, home and remote bean interfaces, resource management, configuring EJB servers, entity beans, JNDI, container-managed and bean-managed persistence, session beans, stateless and stateful beans, transactions, design and performance hints. --This text refers to an out of print or unavailable edition of this title.

Book Description

If you're up on the latest Java technologies, then you know that Enterprise JavaBeans (EJB) 3.0 is the hottest news in Java this year. In fact, EJB 3.0 is being hailed as the new standard of server-side business logic programming. And O'Reilly's award-winning book on EJB has been refreshed just in time to capitalize on the technology's latest rise in popularity.

This fifth edition, written by Bill Burke and Richard Monson-Haefel, has been updated to capture the very latest need-to-know Java technologies in the same award-winning fashion that drove the success of the previous four strong-selling editions. Bill Burke, Chief Architect at JBoss, Inc., represents the company on the EJB 3.0 and Java EE 5 specification committees. Richard Monson-Haefel is one of the world's leading experts on Enterprise Java.

Enterprise JavaBeans 3.0, 5th Edition is organized into two parts: the technical manuscript followed by the JBoss workbook. The technical manuscript explains what EJB is, how it works, and when to use it. The JBoss workbook provides step-by-step instructions for installing, configuring, and running the examples from the manuscript on the JBoss 4.0 Application Server.

Although EJB makes application development much simpler, it's still a complex and ambitious technology that requires a great deal of time to study and master. But now, thanks to Enterprise JavaBeans 3.0, 5th Edition, you can overcome the complexities of EJBs and learn from hundreds of practical examples that are large enough to test key concepts but small enough to be taken apart and explained in the detail that you need. Now you can harness the complexity of EJB with just a single resource by your side.

Featuring myriad changes from its previous versions, EJB 3.0 boasts a very different programming and deployment model, with nearly every aspect of development affected. Even the most experienced EBJ and J2EE developers will need to relearn how to best use EJB to develop mission-critical applications. This author team of experts has taken their combined skills in architecture, development, consulting, and knowledge transfer to explain the various changes to EJB 3.0 as well as the rationale behind these changes. You'll learn the concepts and techniques for authoring distributed, enterprise components in Java from the ground up.

Covering basic through advanced subjects, Mastering Enterprise JavaBeans 3.0 is more than 50 percent new and revised. Four new chapters and one new appendix cover the latest features of this new release, and in-depth coverage of the Java Persistence API and the entities defined therein is provided. The authors' main goal is to get you programming with EJB immediately. To that end, you'll learn:

• How to implement EJB 3.0 beans, with emphasis on session beans (stateful and stateless) and message-driven beans
• Both basic and advanced concepts (such as inheritance, relationships, and so on) of Java Persistence API defined entities
• How to develop and deploy EJB 3.0 Web services
• How to secure EJB applications
• How to integrate EJB applications with the outside world via the Java EE Connector technology
• Tips and techniques for designing and deploying EJB for better performance
• How clustering in large-scale EJB systems works
• Best practices for EJB application design, development, and testing

J2EE FrontEnd Technologies: A Programmer’s Guide to Servlets, JavaServer Pages, and Enterprise JavaBeans concisely and accurately describes what you need to know(TM) about effective enterprise development based on servlets, JSPs, and EJBs. Servlets, JSPs, and EJBs are the most important aspects of Java as it is used in the production of enterprise Web applications today. Lennart “Häxx” Jörelid’s book concentrates on teaching programmers how to fit the various technologies together while spending as little time as possible on “plumbing.”

Jorelid discusses servlet development and architecture, and he teaches developers how to integrate servlets into distributed enterprise systems with illustrated examples. He explains the architecture and implementation of JSPs—including introductory concepts such as using all built-in facilities of the JSP library and advanced topics such as creating your own custom actions using the JSP Tag Library API.

Jorelid also addresses the open-source Struts framework from the Apache software Foundation, which provides a powerful framework for J2EE Web application development by combining servlets and JSPs. And, finally, Jorelid explores the EJB programming paradigm, covering development and architecture of EJBs and J2EE integration and deployment.

J2EE FrontEnd Technologies: A Programmer’s Guide to Servlets, JavaServer Pages, and Enterprise JavaBeans provides developers with a unique approach to understanding the profound relationship between servlets, JSPs, and EJBs. Developers will gain a clear understanding of all three and will be able to harness this knowledge for their own real-world applications.
