The Java scripting API added in Java SE 6 and backward compatibility with Java SE 5 allows dozens of scripting languages to be called at run time from a Java application in a simple, unified way. Part 1 of this two-part article introduces the API's basic features. Part 2 exposes more of its power, demonstrating how external scripts written in Ruby, Groovy, and JavaScript can be executed and altered at run time to change business logic without stopping and restarting the application.

Sinatra is a library that allows you to build almost any kind of web-based application in a very simple manner. When you code in Sinatra you’re bound only by HTTP and your Ruby knowledge. You'll obviously want to start building tiny web-applications and small services, and that's just what we'll do in this article. By the end of this article by Satish Talim, you'll be able to understand:
* what Sinatra is
* how to install Sinatra and its dependencies
* how to build a tiny web-application
* how to deploy the tiny web-app to Heroku

This short paper is intended as a trial balloon of the evaluation of open source software, by measuring the productivity of programming language Ruby and web application framework Ruby on Rails, compared with other open source software.

Ruby on Rails development and Java development differ in fundamental ways. In this article, Bruce Tate outlines the major differences he's discovered by using Rails to develop a complex, scalable Web site from the ground up.

Ant is arguably the de facto build tool for the Java™ platform; however, other build tools, which support a more expressive paradigm that XML lacks, are entering the scene. In this installment of Automation for the people, automation expert Paul Duvall describes how Raven, a build platform built on top of Ruby, leverages the power of a full-featured programming language with the simplicity of a build-centric Domain Specific Language.

With the increasing interest in Ruby on Rails from companies in the enterprise world, some observers have posed questions about its suitability when it comes to the demanding requirements in this arena. One issue that some have called attention to is that ActiveRecord, Rails' Object-Relational Mapper (ORM), doesn't use prepared statements—or at least it didn't until now. With the latest release of DB2® on Rails, parameterized queries are automatically available and bring with them important performance and security benefits to Rails applications.

Learn to extend the Ruby programming language using the Rice interface to Ruby's native C API. Using this object-oriented interface, you can create Ruby objects in C++ code, convert data objects between Ruby and C++, and more.

I’ll be straight with you. I want you to cry. To weep. To whimper sweetly. This book is a poignant guide to Ruby. That means code so beautiful that tears are shed. That means gallant tales and somber truths that have you waking up the next morning in the arms of this book. Hugging it tightly to you all the day long. If necessary, fashion a makeshift hip holster for Why’s (Poignant) Guide to Ruby, so you can always have this book’s tender companionship.

This tutorial will show you how to develop a web-based, database-driven application using Ruby on Rails. Also like the original, it will not teach you how to program in Ruby. On the other hand, if you already know another object-oriented programming language, you should have no problem following along (and at the end you can find links on learning Ruby and lots more).

Understand the basic foundations behind stubbing and mocking techniques and strategies with this hands-on walkthrough using the three most popular mocking frameworks for Ruby.
