In Part 1 of this series, we looked at building a CRUD-based application in minutes with Roo. Here in Part 2, we will extend that application to a full-fledged enterprise application by adding features such as Spring security, email support, and many others.

Spring Roo is a lightweight productivity tool for Java™ technology that makes it fast and easy to develop Spring-based applications. Applications created using Spring Roo follow Spring best practices and are based on standards such as JPA, Bean Validation (JSR-303), and Dependency Injection (JSR-330). Roo offers a usable, context-aware, tab-completing shell for building applications. Spring Roo is extensible and allows add-ons, enhancing its capability. This article introduces Spring Roo and provides step-by-step instructions on building Spring Roo source on Windows® and *nix systems.

Almost every application has to access data to do its work. Hades is an open source library that's built on top of JPA and Spring to aid the creation of DAOs by reducing the effort required.

This article explores tuning techniques for Hibernate applications, focusing on poorly documented topics, such as inheritance mapping, second level cache and enhanced sequence identifier generators.

The Yahoo! User Interface (YUI) Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, DHTML, and AJAX. This articlel cover:
* Making your first AJAX request
* Exploring the callback object properties
* Exploring the response object properties
* Using callback event functions

One of the greatest challenges for mobile applications is the synchronicity of data. An interesting solution to the problem is to use the NoSQL database CouchDB. CouchDB, a document-oriented database, is an alternative to SQL databases. With CouchDB you can use cloud functions on mobile devices, work offline with a locally deployed application on a local data storage, and share data with the rest of the cloud when going online again. In this article, learn the CouchDB concepts by creating and deploying a sample application.
