Usage of Regular Expression for validation

To use the Regular Expression facility will save a lot of coding. It works perfect together with Grails validation in Domain or Command classes. You should use it!

Latest stable Grails Framework Version 1.0.3

Grails platform leverages Groovy, Java, Spring, Hibernate etc. for Web app development for J2EE.
Articel to the Version 1.0: http://www.infoworld.com/article/08/02/05/groovy-10_1.html
"What we’re trying to achieve is really to fundamentally simplify Java EE [Enterprise Edition] development," said Graeme Rocher, creater of the Grails project and CTO at G2One.

I absolute agree with the simplify of the J2EE Environment. It's fun, fast and great to work with. Grails is basically my first experience (except Java itself) with open source development. It opened a new world for me and after the first struggle and hard time to get along with, I really enjoy it now and can see all the potential which is behind it.

Grails aims to bring the "coding by convention" paradigm to Groovy. It's an open-source web application framework that leverages the Groovy language and complements Java Web development. You can use Grails as a standalone development environment that hides all configuration details or integrate your Java business logic. Grails aims to make development as simple as possible and hence should appeal to a wide range of developers not just those from the Java community.
