Web Services - A Business Perspective on Platform Choice
By Ben van Eyle
This paper examines "Web Services", the latest offering in the internet and information technology arena. It outlines what Web Services are, investigates offerings that exist currently, outlines what this means for enterprises, and provides a strategic recommendation for adoption and implementation. In particular, it seeks to show the effective differences and potential benefits and disadvantages between the Microsoft .NET architecture and the Java Platform.

SHAPE THE NEXT SET OF DEFINITIVE J2EE BOOKS
TheServerSide.com is hosting two new J2EE book projects: Mastering EJB II, and EJB Design Patterns. Chapters from these two new books will be posted to TSS as they are written for public feedback. For the first time ever you will be able to directly participate in the writing of these two influential books and personally influence thousands of developers who will learn from them.

Mastering Enterprise Java Beans II
Choosing an EJB Server
1st public review posting, By Ed Roman
Perhaps an even more daunting task than learning about EJB is choosing from the legion of container/server product vendors out there--and currently there are over 32 such products. For the uninformed, this is a very harrowing task. Fortunately, as EJB matures, the industry will begin to consolidate and larger players will emerge from the pack. But until then, what should you be looking for when choosing an EJB product...........

Corba Appendix
1st public review posting, By Ed Roman
CORBA allows EJB customers to communicate with existing CORBA applications, as well as integrate with existing investments written in non-Java languages such as C++ and COBOL. In this appendix, we'll learn the high-level concepts behind CORBA. We'll then see how J2EE can integrate with CORBA via RMI-IIOP. Finally, we'll look at how to use CORBA clients to access EJB systems...........

RMI-IIOP and JNDI Appendix
1st public review posting, By Ed Roman
To help you to truly understand EJB, this appendix explains the technologies that EJB depends upon--namely Java RMI-IIOP and the Java Naming and Directory Interface (JNDI). The goal of this appendix is to teach you enough about RMI-IIOP and JNDI so that you can be productive in an EJB environment..........

EJB Quick Reference
1st public review posting, By Ed Roman
This appendix is a quick reference for programmers to use during EJB development. In the first section of this appendix, you'll find diagrams illustrating what's really going on in an EJB system. These diagrams were taken directly from the EJB specification; I've condensed the diagrams and commented them to clarify their meaning. You'll also find summaries and explanations of each method in the EJB architecture, as well as a transaction reference.........

EJB Design Patterns
Value Objects
4th public review posting, By Floyd MarinescuHow can a client exchange bulk data with the server without making multiple fine-grained network calls?
In any distributed application there are two ways that a client can interact with a server. The first is to read some data from the server for display purposes; the second is to change some data on the server by creating, updating or removing data. In an EJB context, these types of operations typically involve the exchange of data between the client (servlet, applet, etc), and a Session Bean, Entity Bean, or Message Driven Bean. ........

Value Object Factory
3rd public review posting, By Floyd MarinescuHow should value object creation and consumption logic be implemented, in order to minimize the impact of frequent changes in the value object layer on the rest of the system?
Value Objects have a tendency to change often. Domain Value Objects change whenever the domain objects change (adding a new attribute to an entity bean, etc). Custom Value Objects are just use case specific data holders for transporting data across a network; they can change as frequently as your application's presentation view. A medium to large application could potentially have tens to even hundreds of different Value Objects, each of which would require custom logic to create it. A critical question then becomes: how and where should this logic be implemented, in order to decouple and protect the rest of this system from value object changes........

EJB Home Factory
1st public review posting, By Floyd MarinescuHow can a client lookup an EJB home only once in the lifetime of its application, and abstract the details of that lookup?
The JNDI lookup of an enterprise beans home method is the first step to getting access to the remote interface of an EJB. In order to get access to this interface, the client must go through the code-intensive and expensive process of getting access to the InitialContext, followed by performing the actual lookup of the EJB home, casting it and handling exceptions ........

NEW J2EE PATTERNS
CoarseGrained BMP fat key pattern
By Wang Minjiang
In Gene's Fat key pattern, the pk is used to store the data in order to minimise the redundant db hit. But it may not work in cluster with bean cache in WLS. This pattern also provides these benifts, and more. And it differs in the sense that it is a coarseGrain BMP pattern.

NEW APPLICATION SERVER REVIEWS
Free Dynamo! Why DAS rocks my world
By Todd Jonker
Dynamo's Nucleus component configuration system is incredibly powerful, and I'd love to be able to use it for *any* kind of Java application, not just Web apps. Adding new components takes seconds (just add a config file), you can reconfigure any system component (override the config file and/or the implementing class), and you can view (and modify!) the runtime state of any component in the system using the DCC. The hierarchical structure, and the fact that you can drop in any JavaBean, makes it truly wonderful to use.

KEY J2EE INDUSTRY HEADLINES
ECperf launches homepage on TheServerSide.com
ECperf is a Specification and implementation of a benchmark designed to measure performance and scalability of J2EE servers. ECperf was prototyped and built in conjunction with J2EE server vendors, under the Java Community Process. As J2EE server benchmark results come in, they will be posted on ecperf.theserverside.com and announced on TheServerSide's homepage.

BEA and Intel announce partnership
BEA and Intel have partnered to help promote each others products. "For Intel, the deal with BEA is a vote of confidence as it tries to crack the profitable high-end server market with its faster Itanium processors." For BEA this deal will gain it the massive marketing and sales power of Intel, giving it the chance to be the defacto solution for Itanium based servers.

WebSphere tops in independant benchmark
Given BEA and Oracles recent claims regarding their own benchmarks, it's interesting to look at PC Magazine's independant benchmarks (published in May) where the vendors themselves tuned an application. Interestingly, both BEA and Oracle declined to put their super fast servers in the running for some reason.

The future of IBM Visual Age (and other Java IDE's)
A new article from IBM implies that they are dropping Visual Age for Java and re-writing their tools to the WebSphere tools line because VisualAge is too "language-centric".

EJB 2.0 completes JCP approval process
Sun Microsystems said Monday that the long-awaited next version of Enterprise Java Beans 2.0 (EJB) -- the specification for components encapsulating business logic in Java applications--has completed the approval process of the Java Community Process (JCP). This calls for celebration - Local interfaces are here to stay!

Java Decaffeinated in Windows Xp
Changes to security settings and their definitions in the Release Candidate 1 (RC 1) of Windows XP could deny millions of users email and web browser access to Java applets on websites and HTML-based email. J2EE developers using applets as a rich client platform should be aware - your programs might not work for end users under XP's default security settings.

HyperQbs 2.1 released, with full Java Server Faces support
HyperQbs framework is the first fully compliant and ready to market implementation of the new standard for visual component assembly, which is being defined in the JavaServer Faces specification (JSR 127) under the Java Community Process.

BEA ships Weblogic Integration
BEA today announced the general availability of BEA WebLogic Integration. BEA Weblogic Integration is a new repackaged and integrated offering of Weblogic Server, WL Process Integrator (WLPI), WL Collaborator (WLC), and BEA's JCA implementation. WLPI and WLC are no longer be available as standalone products. BEA Weblogic Integration brings BEA's offering closer to the 'Service Broker' concept described by Billy Newport in a recent article.
