Java 2 Enterprise Edition
Developer's Guide This book describes how to develop and deploy enterprise beans for the JavaTM 2 SDK, Enterprise Edition (J2EETM SDK). The J2EE SDK is the reference implementation provided by Sun Microsystems, Inc. for the J2EE platform, a component-based architecture for creating object-oriented, enterprise-level applications.
The components, which are called enterprise beans, implement business tasks or business entities.
The JavaTM 2 SDK, Enterprise Edition (J2EE SDK) is the reference implementation provided by Sun Microsystems, Inc.
The J2EE server provides the following services:
* Naming and Directory - allows programs to locate services and components through the Java Naming and Directory InterfaceTM (JNDI) API
* Authentication - enforces security by requiring users to log in
* HTTP - enables Web browsers to access servlets and JavaServer PagesTM (JSP) files
* EJB - allows clients to invoke methods on enterprise beans
java Topic tutorial Java is designed to be architecturally neutral so it can run on multiple platforms. The same runtime code can run any platform which supports Java.
To achieve its cross-architecture capabilities, the Java compiler generates architecturally neutral bytecode instructions.
Java is a fully object-oriented language and it can be used
* create applets for viewing within a browser,
standalone client-side application,
* create standalone client-side applications
* create middle-tier components (Servlets/JSP) for
generating web page with dynamic content and parsing webpages coming back
from the client
* create middle tier component (Enterprise JavaBeans
or EJB) for implementing business logic and updating the database
* create procedures that run within a database and are
callable from other database procedures
The J2EE 1.4 Tutorial for NetBeans IDE 4.1 The J2EE 1.4 Tutorial in NetBeans IDE is a guide to developing enterprise applications for the Java 2 Platform, Enterprise Edition (J2EE) version 1.4. This tutorial examines several aspects of J2EE technology and how to quickly and easily code enterprise applications using NetBeans IDE. Here we cover all the things you need to know to make the best use of this tutorial.
This tutorial is intended for programmers who are interested in developing and deploying J2EE 1.4 applications on the Sun Java System Application Server Platform Edition 8.1.
Each of the examples is set up as a NetBeans project. You just have to open the projects, occasionally resolve the location of a missing JAR file on the classpath, and you can build and deploy the project to your Application Server without any additional configuration.
Prepare for the Computer Science AP
exam The goal of this book, and this class, is to teach you to think like a computer scientist. I like the way computer scientists think because they combine some of the best features of Mathematics, Engineering, and Natural Science. Like mathematicians, computer scientists use formal languages to denote ideas. Like engineers, they design things, assembling components into systems and evaluating tradeoffs among alternatives. Like scientists, they observe the behavior of complex systems, form hypotheses, and test predictions.
The single most important skill for a computer scientist is problem-solving. By that I mean the ability to formulate problems, think creatively about solutions, and express a solution clearly and accurately. As it turns out, the process of learning to program is an excellent opportunity to practice problem-solving skills. That's why this chapter is called "The way of the program."
Data Structures and Algorithms with Object-Oriented Design Patterns in Java
This book was motivated by my experience in teaching the course E&CE 250: Algorithms and Data Structures in the Computer Engineering program at the University of Waterloo. I have observed that the advent of object-oriented methods and the emergence of object-oriented design patterns has lead to a profound change in the pedagogy of data structures and algorithms. The successful application of these techniques gives rise to a kind of cognitive unification: Ideas that are disparate and apparently unrelated seem to come together when the appropriate design patterns and abstractions are used.
This paradigm shift is both evolutionary and revolutionary. On the one hand, the knowledge base grows incrementally as programmers and researchers invent new algorithms and data structures.
