Ruby on Rails for Java Technology Developers (SEM-DTJ-2135)

Ruby on Rails for Java Technology Developers (SEM-DTJ-2135)
 
Email Product Description

Ruby on Rails is a framework for quickly building web applications. Rails takes advantage of many of the lessons learned over the past decade of web development. Rails uses Model/View/Controller (MVC), view templates, sessions, cookies, and many other abstractions that developers in any web framework will find familiar.But Rails improves on the past as well. With convention over configuration, you use configuration only where necessary, so simple applications do not require hundreds of lines of boilerplate XML.In this session you will learn why Rails is so powerful, and why other frameworks are racing to emulate Rails best features. Best of all, Ruby and Java technology are growing together. With JRuby, you can run your Rails apps on a Java technology-based VM, and continue to access the enormous base of useful Java libraries. You will see how easy it is to get an application started with JRuby on Rails.
