You inevitably spend some part of your week crunching code that you didn't write, and for which you may not have the source. This beginner's guide to opening up and locking down Java code walks you through the essentials of disassembling, decompiling, and obfuscating Java code, using examples from popular tools such as Mocha, HoseMocha, jmangle, and JODE.

Creating a fully internationalized Java application using PropertyResourceBundles can present some interesting design and implementation problems, including concern over how to modularize the bundles to be used in different areas of the application. This article explores a solution based on PropertyResourceBundles, which should simplify the design and implementation problems, while promoting reuse of existing bundles. Article includes code snippets.

If you want to build and run faster Java applications on the IBM Developer Kit for Linux, version 1.3, roll up your sleeves and prepare to get dirty. This article provides hands-on instruction for profiling, monitoring, and performance tuning not only your IBM Developer Kit, but your hardware capacity, the Linux 2.2.x kernel, and your Java applications.

GUIs are generally designed with a model-view-controller architecture in which the view is decoupled from the model. The separation presents a challenge to automated testing because it's difficult to verify that a state change in the model is reflected appropriately in the view -- it spawns the infamous "Liar View." This installment of Diagnosing Java Code examines the Liar View bug pattern.

If you've ever wanted to build your own supercomputer but have been held back by the demands of parallel programming in C, Pseudo Remote Threads is for you. This prize-winning Java programming model greatly simplifies parallel programming on clusters, bringing supercomputing out of the laboratory and into the hands of everyday Java programmers. Article includes code snipets.

A brief introduction to writing your own first Java Server Pages (JSP). Covers several different editions of "Hello, World!" example. This article is the first excerpt of a full series from the book, Web Development with JavaServer Pages.

There are two primary types of tag conventions in Java Server Pages: Scripting-Oriented Tags and XML-Based Tags. Learning them gives you insight not only into JSP, but XML, too. This article is the second excerpt in a series from the book, "Web Development with JavaServer Pages."

This tutorial discusses the creation and use of cookies in Servlets. Includes an example of a customized search engine interface.

A concise list of frequently asked questions regarding JavaBeans. Includes what JavaBeans are, what you need to use JavaBeans, the difference between Java applets and JavaBean components, Enterprise JavaBean component, and more.

This article describes the overall servlet architecture and what you need to develop your application with servlets. Also presented are several code examples to show you how to use the Servlet API, and compare it with CGI and proprietary server APIs where appropriate.

The author notes "This document explains the concepts of Java Servlets and provides a step-by-step tutorial for writing HTTP Servlets with complete source code for the example Servlets. The tutorial and the other chapters cover all facets of Servlet programming from a simple "Hello World" Servlet to advanced Servlet features like session tracking and Cookies. There are also appendices on compiling and running Servlets. The reader is assumed to have some basic knowledge of HTML and Java programming."

This article describes advantages and disadvantages of Servlets vs CGI, How a Servlet works, and Where a Servlet can be used for.

Written primarily for those currently developing on the server in JavaScript, this article explains the basics of working with Java on the server through Sun's Java Servlet API. It includes a brief overview of servlets and their role in server-side software development, and Comparison of JavaScript applications with servlets in a number of crucial areas of program design.

In this 5-page tutorial, you'll learn how to write, compile, and serve a simple servlet. Also, includes other servlet-related resources.

Window toolkits typically provide a layout mechanism that positions widgets in a container. For example, AWT and Swing have layout managers, and VisualWorks Smalltalk has wrappers. This article presents a template mechanism for JSP that allows layout to be encapsulated and reused. JSP templates minimize the impact of layout changes and encourage modular design.

JavaServer Pages (JSP) are a great mechanism for delivering dynamic Web-based content. JSP provides a set of predefined tags, but you can also define your own tag extensions that encapsulate common functionality. This article will show how easy it is to build, deploy, and use your own custom JSP tag, using the Servlet/JSP reference implementation, Tomcat.

This is a short introductory article on JavaServer Pages. It talks about the features of JSP, a simple example, and includes some useful JSP related-links.

Adapted from a chapter of the book Web Development with JavaServer Pages, this article is written for developers who want to create their own Beans for use as JSP components, and for interested web designers who want to understand how these components are implemented behind the scenes. It is not necessary to understand the details of Beans development to work with JSP. As component architectures go, the interface between JSP and Beans is quite simple.

JavaBeans are Java's answer to Microsoft's ActiveX components. A JavaBean is the architecture for using and building components in Java. A bean can be either a visual object�meaning you can change the properties of a component by changing a radio button or similar object�or a nonvisual object. Rather than show you how to build JavaBeans (which could be the subject of an entire book), this tutorial will show you how to integrate JSP with a preexisting bean.

This is a sample chapter from the book 'Professional JSP' by Wrox Press. Inarguably the best book to master Java Server Pages.
