Script Name Adding JRuby to your Java Toolbox JRuby combines the object-oriented strength of Smalltalk, the expressiveness of Perl, and the flexibility of the Java class libraries into a single, efficient rapid development framework for the Java platform. In this third installment in the alt.lang.jre series, Michael Squillace and Barry Feigenbaum introduce JRuby, a sophisticated addition to your Java development toolbox. Generate Certificate Chains for Testing Java Applications Learn how to create digital-certificate chains to test your software. IBM Software Engineer, Paul H. Abbott, clarifies this seldom-documented process by showing you how to use the freely available OpenSSL toolkit to create a certificate chain of any length. He also describes common certificate attributes and shows you some sample Java code for reading the certificates you create into a Java keystore. Reference Monitor for Tivoli Privacy Manager The Reference Monitor's purpose is to simplify the task of developing new privacy monitors, which are integration points between an application and the Privacy Manager server. IBM Tivoli Privacy Manager provides a way for businesses to meet various privacy regulations. It incorporates a privacy management middleware system that applies privacy rules to existing applications while minimizing the impact to the environment. Structural Analysis for Java SA4J is a technology that analyzes structural dependencies of Java applications in order to measure their stability. It detects structural "anti-patterns" (suspicious design elements) and provides dependency web browsing for detailed exploration of anti-patterns in the dependency web. SA4J also enables "what if" analysis in order to assess the impact of change on the functionality of the application; and it offers guidelines for package re-factoring. Calculate Distance Between Two Points Using Longitude & Latitude Tutorial and sample codes to calculate the distance between two locations. Free sample source codes in PHP, ASP, ColdFusion, C/C++, C#, Java, Perl, Visual Basic and Javascript. Longitude and latitude for United States ZIP Code and Canadian Postal Code are available in database subscription. Instant logging: Harness the power of log4j with Jabber Not only is logging an important element in development and testing cycles -- providing crucial debugging information -- it is also useful for detecting bugs once a system has been deployed in a production environment, providing precise context information to fix them. In this article, Ruth Zamorano and Rafael Luque, cofounders of Orange Soft, a Spain-based software company specializing in object-oriented technologies, server-side Java platform, and Web content accessibility, explain how to use the extension ability of log4j to enable your distributed Java applications to be monitored by instant messaging (IM). Application Tools for Extension Services Application Tools for Extension Services consist of WebSphere® Studio-based tools that support the development of Web applications targeted for the Extension Services for WebSphere Everyplace (ESWE) platform. These tools are based on the existing WebSphere Studio J2EE development tools and they are part of an emerging suite of tools for the ESWE platform. JAR Class Finder JAR Class Finder is a WSAD/Eclipse plug-in utility for finding JAR files containing a given class for the Java build path of a project and for helping to fix NoClassDefFound exceptions. This utility helps users to quickly and easily resolve ClassDefNotFound exceptions, which commonly occur during run time. It can also be used to avoid getting such errors if used before run time. Jikes Bytecode Toolkit Jikes Bytecode Toolkit is a 100% Java class library that enables Java programs to create, read, and write binary Java class files and to query and update a single, high-level representation of the collection of them, including relationships among them. These features allow the development of tools that report on what APIs the classes use, reorder and change instructions, merge or extend classes, add customized instrumentation (similar to profilers), analyze control and data flow, etc. Solution Enabler Solution Enabler is a framework for creating and deploying solutions locally or to remote machines with different operating systems. The framework helps to simplify the creation and deployment of software solutions by capturing detailed knowledge of a solution package deployed through a common installer.
