What are Grails in Java?
As Web applications grow more complicated, the need for comprehensive foundations to build them grows more and more. These foundations come in different varieties. Two significant ways to manage large Web projects are by simplifying the programming code involved in building Web applications and constructing frameworks that offer programmers a comprehensive suite of tools in order to develop with. Grails, a combination of a Java framework with the Groovy programming language, based on Java, aims to do just that.

Groovy
-
Groovy represents an adaptation of Java for the Java Virtual Machine (JVM) intended to ease coding applications for the Web. Based primarily on Java, Groovy also implements numerous facets of other programming languages such as SmallTalk, Python, and Ruby. These adaptations are meant to make Groovy easy to learn, use, and implement in large scale projects. At the same time, Groovy works seamlessly with Java classes and libraries.
Web Frameworks
-
Web frameworks represent efforts to centralize facets of project development in order to increase programmer productivity. Instead of having programmers using a variety of tools that perhaps do not work together out of the box, Web frameworks take care of the nitty-gritty code in order to free programmers from having to "reinvent the wheel" in each project. Frameworks offer centralized tools and code libraries that already link code to databases, interactive development environments, and specialized libraries. This means that programmers can begin working immediately with quick results.

Grails
-
A Web framework built on Groovy, Grails represents an effort to increase efficiency and productivity in online Java development. The Grails project allows programmers to begin coding projects meant for the Web, ready to interface with Web servers and databases. Built with Groovy, this means that many Java libraries and conventions can be imported into Grails to increase flexibility.
Grails Consulting
-
Since purchased by SpringSource, Grails also comes complete with a consulting service. SpringSource offers a variety of consulting services to compliment Grails, such technical support and online consulting. Even better, SpringSource also offers migration assistance and architectural evaluations, to help companies still considering a migration to the Grails framework make educated decisions.
