EJB 2.0 is testimony to the fact that the J2EE model has come a long way. You can do a lot of things with 2.0 that were tedious and error-prone in EJB 1.1. The Container Managed Persistence (CMP) relationship management alone makes it worthwhile. Just define all database access through method calls on entity beans, configure the deployment descriptors to recognize the method calls, set the autogeneration of RDBMS tables to "true," start the server, and you're ready to rumble. No more mucking around with databases. Once your DBA has set up your relational database, you never have to look at it again. As far as your application is concerned, you deal in objects, whole objects, and nothing but objects. Right? Wrong! While the EJB 2.0 architecture definitely alleviates the pain of dealing with databases directly, it cannot completely eliminate it. Note that I'm not mak... (more)

An Airline Ticket Store Using Java and ColdFusion

Online stores are the new, next-generation, "revolutionize the world as we see it today" way of doing business. In the context of business transactions, online stores use the global Internet to facilitate purchase and sale of goods and services. The ability to support online sales is an essential component of the new e-commerce paradigm for Internet-based businesses today. Putting together an enterprise-level application for an Internet store involves design and integration of various technologies that play specific roles in a distributed computing environment. A distributed topo... (more)

An Introduction to EJBs With Lots of Code

This was actually the first book on Enterprise JavaBeans that came into the market. Enterprise JavaBeans was released in June and made its debut at JavaOne this year. This is a pretty good book for developers who like to see a lot of code. The examples in the book are used to develop a fairly complex application and the code isn't meant for novices. Tom Valesky presents many examples. I like the fact that the book takes an example and builds its complexity in successive chapters. There's good coverage of distributed architectures and transactions. The author has also dedicated a ... (more)

Welcome to XML

I have to agree with JDJ's editor-in-chief, Sean Rhody. The word XML seems to spark technological fires. The JavaOne Conference issue of JDJ (Vol. 4, issue 6) featured three articles on XML. Having written one of them, I share the experience of the flood of e-mails regarding this obviously hot and controversial topic. Aside from the folks who actually read what I write, others who have little clue about programming have asked me what XML is. As Sean mentioned, at JDJ we've been tossing e-mails back and forth about XML, where it is today, what it may mean and what role SYS-CON Pub... (more)

Presenting Java

In the fast-changing world of Internet-based technologies, perception is everything. Is a business solution implemented in a particular technology truly cross-platform? Is it scalable? Is it robust? Is it easy to use? Does it do what it set out to do? Most times the answers to these questions are based on the perception of the functionality offered by the application. In a distributed application a large part of the burden of providing the perception falls on the designers of the user interface. One of Java's salient features - platform interoperability - is achieved via the perc... (more)
