| OverviewVolume 1 of this advanced 3-volume guide explores the
infrastructure issues so important to good application
design. It isn't just a book about Entity Beans and JNDI. It
takes you step by step through building the back end,
designing the data store so that it gives you convenient
access to the data your application needs; designing a
directory; figuring out how to handle security and where to
store security credentials you need; and so on. Editorial Reviews| Amazon.com | | Aimed at the more experienced Java developer, Building Java Enterprise Applications provides a detailed tour of the best practices for today's J2EE architecture. Filled with particularly good advice on using Enterprise JavaBeans (EJBs) and LDAP directory services, this title lays the groundwork for building the next generation of Java software. As volume one of a planned three-volume series, this book centers on "blueprints" for using the best of J2EE technologies for creating scalable software. The focus here is on a meaningful, single practical case study on a database for a brokerage house. The selection of leading-edge technologies (EJB and LDAP) are what real Java developers are likely to face on the job, and the author's knowledgeable and thorough explanation of all the relevant details of implementing the sample system sets a high standard. Early sections define the scope and requirements of the model database and directory server. The author then turns to implementing the database, including building tables. (Actual SQL for different databases including Oracle and MySQL is included in an appendix.) Similarly, the "real" details of modeling a directory server (using LDAP) is set out to show how users, passwords, and other information can be leveraged across a larger organization. After the groundwork is in place, this text zeroes in on using Enterprise JavaBeans (EJB) 2.0 to model each business entity in the system (as well as application logic). Standout material shows off building an entity EJB with multiple interfaces, classes, and deployment descriptors all clearly presented. The use of the manager session bean to hide the details of JNDI and LDAP comes next, and this bit of intellectual property will surely justify the price of this book for anyone seeking to combine EJBs and LDAP. From here, the application logic gets filled in using other EJB features (like session beans, both stateful and stateless). A later chapter adds asynchronous processing abilities using the Java Message Service (JMS) and the new message bean type, new for EJB 2.0. The assembled system then gets a simple front end to test it out, though the focus clearly is on the data tier. (More on user interfaces is promised in the second volume of this series, which will concentrate on Web applications.) Useful appendices provide the nuts and bolts of running actual software, like OpenLDAP, a free directory server, BEA WebLogic, plus full source code for all beans discussed in this text. All in all, this book is a worthwhile choice for understanding the right ways for designing on the Java platform today when it comes to higher-end enterprise software. --Richard Dragan Topics covered: Introduction to architecture for Java Enterprise applications; case study for a client/broker database for a brokerage with scheduling support, data, business, and presentation layers explained; primer for database design (including SQL, constraints, and tables); designing an LDAP directory (plus directory hierarchies); Enterprise JavaBean 2.0 basics (remote, local, and local home interfaces, plus primary keys); EJB deployment descriptors; implementing sequences for new records in EJBs (a sequence bean); using a manager EJB for JNDI/LDAP processing; connection sharing for performance; adding sample data; deployment; using patterns for business logic with EJBs (the Facade pattern); stateful vs. stateless beans; asynchronous processing and message beans (including JMS basics); extending the data architecture for Web applications (and Web services); appendices for sample SQL scripts and database-specific hints for MySQL, Oracle, and PostgreSQL; and a reference to running OpenLDAP, iPlanet Directory Server, and BEA WebLogic Application Server. |
| | Book Description | | What are the key decisions and tradeoffs you face as you design and develop enterprise applications? How do you build the back end so that it not only handles your current needs but is flexible enough to allow your system to evolve as your needs expand? Answer these questions and many more with Building Java Enterprise Applications, an advanced guide to building complex Java Enterprise Applications from the ground up that addresses design issues along the way. These practical books take a step back from detailed examination of the APIs and focus on the entire picture, so you can put the pieces together and build something that works! This book explores the infrastructure issues so important to good application design. It isn't just a book about doing things with Entity Beans, JDBC and JMS and JNDI. It takes you step by step through building the back end, designing the data store so that it gives you convenient access to the data your application needs; designing a directory; figuring out how to handle security and where to store security credentials you need; and so on. On top of this, it shows -- as easily as possible --how to build the entity bean layer that makes information available to the rest of the application. Throughout this guide, author Brett McLaughlin uses his wealth of real-world experience with enterprise development to show you one step at a time how to design and build a comprehensive enterprise application from the ground up, starting with the back end. |

| Decent, but not what I expected..., 2007-04-13 | | Reviewer rating: |  |
| After reading the synopsis I was ready to delve into some planning and best practices reading material. While the book focuses on a core example, it doesn't not provide enough information on WHY certain decisions were made and does not provide enough look into alternatives.
The book would be much more valuable if it focused less on one concrete example and took a step upwards into what I mistook the synopsis and title for: "Making Strategic and Technology/Business-Driven Decisions in Your Java Applications".
Aside from misinterpreting the content of the book, the general content lacked. Even though providing a path down a single sample, there was far too little focus on how to go about building Java Enterprise applications and too much focus on explaining the code. While the author tried to keep succinct, he did not touch on the core principals and theories enough.
I recommend the book only for casual, quick reading as it is out-dated (due to the EJB 2 topics covered) and does not dive into the real core of planning application life cycles. |
| | Great overview, 2002-10-02 | | Reviewer rating: |  |
| | This book will not teach you all the nitty gritty of J2EE. It will, however, explain when to use what part of the APIs. It goes through a lot of the different parts of J2EE. For me it was a good overview. I started coding J2EE by going in deep from the start. If this book would've been available when I was learning the technology, my path to understanding it all would've been shorter. I especially liked the way the author builds the different elements together to construct a system. It shows how they mix. |
| | Good for getting started w/ J2EE, BUT TOO MANY ERRORS, 2002-08-28 | | Reviewer rating: | |
| | I've often seen complaints about O'Reilly's editing in reviews like this. Now I know what all those folks are complaining about. The diagrams and examples in this book are just plain *BAD*. In the section on DB design I don't think there wasn't one ER diagram with out MULTIPLE errors. Where's the quality control? I would have given 4 stars if the diagrams and examples were corrct. The textual content of the book is actually pretty good, easy to read, but a little slow paced for me. I was initially attracted to the book because of it's promise of bringing multiple J2EE concepts toghether in one read. I'm afraid tho that if I'm left to analyzing and correcting errors in areas that I'm familiar with that I'll be very confused and frustrated by errors in areas I'm not so familar with. I will certainly scrutinize the next two volumes in the series much more closely before I consider buying. |
| | another lousy manpage reprint from ORA, 2002-08-03 | | Reviewer rating: |  |
| | This is yet another one of ORA's buzzword books with next to no original content. If you want a decent book on J2EE, check out the offerings from Manning Press, Addison-Wesley, or Wrox. At least those companies actually edit their books, and see if the printed examples work. |
| | Extremely disappointing, 2002-07-18 | | Reviewer rating: | |
| | I was extremely disappointed by this book. I thought it was a book about how to architect Java applications. It is not. While I appreciate the book's goal of providing practical examples, it is nothing but an example of building one particular application. It's not much more than a tutorial. I want a book of principles, guidelines, best practices for building Java applications - a series of general principles that I can apply to any situation. O'Reilly books are normally great; I bought this book largely because it was from O'Reilly. Big mistake. If you want a book of general principles for how to design a Java enterprise app, Core J2EE Patterns is excellent and much better than this one. |
