ABC is a software development boutique which specializes in open source technologies but with an emphasis in Java.
We write custom J2EE SMB applications that run in the cloud and manage open source projects Pelican & Seal.
We Love :
Pelican & Seal are both J2EE based and can easily be configured and deployed to an application server of choice. The underlying framework prides itself on convention over configuration and produces Spring controller servlets, views and data binding using Hibernate, the same you see in stand alone pure java based application. The language, that sits on top of it all is called Groovy. Its syntax is object oriented, fun and fast. Whats really great is that you can write both Groovy & Java in a Groovy class file, very powerful.
Both projects are easy to customize on your own once you understand the layout
I recommend the following book : The Definitive Guide to Grails. Some of the content may be dated and a newer book or documentation may help fill in the blanks but is a great primer.
