Description:
The enterprise Java universe--spanning at least 15 Java APIs and at least twice that many protocols and technologies--is tremendously complex and can appear completely impenetrable to a newcomer. Even if you're competent in Java programming, and even if you know what n-tier programming is all about conceptually, the sheer magnitude of making a Java 2 Enterprise Edition (J2EE) application work is intimidating. Pravin Tulachan aims to--and by and large succeeds--untangle the alphabet soup of APIs and show you how to write working J2EE software. He commits none of the popular sins of J2EE books (he neither tries to teach basic Java, neglects the design issues that are critical to J2EE projects, nor glosses too much over deployment). This is a solid book, worth the time of experienced Java hands who want to take the leap into distributed architecture and programming. Tulachan likes to intermix his code with his prose. He typically explains the need for some procedure to happen next in his design, and then proceeds to show the actual code that does the job. His treatment of the Java Naming and Directory Interface (JNDI) is typical. He explains what JNDI is all about, and then steps through the process of connecting to the local Lightweight Directory Access Protocol (LDAP) environment and running the required queries against it. It's a strategy that works, made better by the fact that he sticks to the Sun iPlanet reference implementation of the J2EE application server. --David Wall Topics covered: How to write Enterprise Java Beans (EJB) in the Java 2 Enterprise Edition (J2EE) environment. Detailed coverage goes to different kinds of beans and different strategies for persistence management, and to deployment under the Sun iPlanet environment, which is more or less standard.
