Part I. Why Enterprise JavaBeans?

If your path to Enterprise Java is anything like mine, you’ve arrived here hoping to be more productive in application development. Perhaps you’ve heard some good or bad things about this thing called “EJB,” and you’d like to explore some more. Perhaps some EJB technology is already in place at work, and you’re looking to understand it a bit deeper.

The fact is that Enterprise JavaBeans is much more than a set of APIs. It is a simplified programming model that, when understood at a conceptual level, has the power to easily adapt lightweight Java classes into powerful business components. In short, EJB lets you focus on the work you do best—writing your application logic.

In this section we’ll start with a bird’s-eye view of the issues facing every software developer, examining how EJB removes common problems from your concern.
