J2EE and XML Development

INTRODUCTION TO PROGRAMMING USING JAVA' is a free, on-line textbook. It is suitable for use in an introductory programming course and for people who are trying to learn programming on their own. There is probably enough material for a full year College programming course. There are no prerequisites beyond a general familiarity with the ideas of computers and programs.

Teach Yourself Java in 21 Days

Based on the enormous amount of press Java is getting and the amount of excitement it has generated, you may get the impression that Java will save the world-or at least solve all the problems of the Internet. Not so. Java's hype has run far ahead of its capabilities, and while Java is indeed new and interesting, it really is another programming language with which you write programs that run on the Internet. In this respect, Java is closer to popular programming languages such as C, C++, Visual Basic, or Pascal, than it is to a page description language such as HTML, or a very simple scripting language such as JavaScript.

Java, 2nd Edition

Like any human language, Java provides a way to express concepts. If successful, this medium of expression will be significantly easier and more flexible than the alternatives as problems grow larger and more complex.

EJB Design Patterns

The job of the EJB developer is constantly challenging, making the task of designing maintainable and scalable systems difficult without a clear set of best practices to follow. It is with this and other concerns in mind that Floyd Marinescu (Director of TheServerSide.com J2EE Community) worked with thousands of J2EE professionals on TheServerSide to put their collective knowledge together in order to build a library of design patterns, strategies, and best practices for EJB design and development.

Data Structures and Algorithms With Object-Oriented Design Patterns in Java

This book is about the fundamentals of data structures and algorithms--the basic elements from which large and complex software artifacts are built. To develop a solid understanding of a data structure requires three things: First, you must learn how the information is arranged in the memory of the computer. Second, you must become familiar with the algorithms for manipulating the information contained in the data structure. And third, you must understand the performance characteristics of the data structure so that when called upon to select a suitable data structure for a particular application, you are able to make an appropriate decision.

Securing Java

We hope this book appeals to geeks and grandmothers alike (not that some grandmothers aren't geeks). Although it gets technical in places, we hope the messages are clear enough that even the casual Web user comes away with a broader understanding of the security issues surrounding mobile code. We kept four groups in mind as we wrote this book: Web users, developers, system administrators, and business decision-makers. Many of the issues of mobile code security cut across these groups. As Java integrates itself into the foundations of electronic commerce, Java security issues take on more urgency.

JXTA

* This book presents a guided tour of the JXTA platform, including all of the critical information required to begin producing P2P solutions built on top of JXTA. Reference information on each of the JXTA protocols provides an understanding of the underlying principles of P2P networking, and examples built on the JXTA reference implementation provide the hands-on experience necessary to become fluent in JXTA technology.
