Groovy is an agile dynamic language for the Java platform. The language and its libraries bring many things to the table to ease the process of building applications for the Java platform. This session provides a detailed run through Groovy with lots of code samples to drive home the power of the language.

Dynamic languages provide a lot of power and flexibility compared to statically typed languages. Groovy brings that power and flexibility to the Java platform in a way that is totally compatible with all of your existing Java code, tools and infrastructure. This session covers all of the fundamentals of Groovy and gives developers a whole lot of practical information they need to get started with the language.

There are many features provided by The Grails Framework which at first appear to be black magic. Where does the 'log' property come from? How do GORM dynamic finders really work? How can I add similar properties and behavior to classes at runtime? All of these questions will be answered during this session.

This session is for Grails developers who want to accelerate their Grails Kung-Fu to the next level and really take advantage of the power and flexibility that Grails has to offer.

Everyone knows that Grails provides a fantastic MVC framework for building web applications. What many developers do not realize is that Grails provides a truly powerful and flexible application platform that may be used to build applications that do not have a browser front end at all.

In this session we will discuss Grails as an application platform. The lecture and demonstrations will focus on using Grails to build the service layer of a layered application architecture. The Grails service layer may be accessed from a wide array of technologies including Swing applications, .NET applications, other Grails applications and much more. Building a service layer for The Java Platform has never been easier.

The Spring Framework is the most comprehensive and most powerful application platform ever built on top of The Java Platform. Spring is the de facto standard platform for building enterprise Java applications. Groovy has always integrated very well with Spring. Spring is an absolutely integral component that supports much of the power, flexibility and ease of development offered by Grails.

This session presents a detailed technical discussion of many of the ways that these technologies all play well together. Topics will include:

• Writing Spring Beans In Groovy
• The Groovy Spring Bean Builder
• Dependency Injection In Grails
• Spring's Database Transaction Management In Grails
• Spring MVC and Grails
• Configuring The Spring Application Context To Add Whole New -Capabilities To A Grails App
• Spring Remoting In Grails

Grails is one of the most flexible and most powerful frameworks on The Java Platform. Grails leverages the flexibility offered by the platform in a way that other web frameworks do not. Grails is a fantastic platform for polglot web programming.

Part of what makes Grails so compelling is its really powerful plugin system. The Grails plugin system allows capabilities to be bolted on to applications, including adding support for a variety of programming languages. All of the major programming languages available on the JVM are supported by The Grails Framework. These include Java, Groovy, Scala, Clojure and others. This session will dive in to that aspect of the framework with a focus on Scala and Clojure and will demonstrate what is involved in adding support for new languages.

Prerequisite: Advanced Grails

The dynamic nature of Groovy makes it a fantastic language for building dynamic applications for the Java Platform. The metaprogramming capabilities offered by the language provide everything that an application development team needs to build systems that are far more capable than their all Java counterparts. Taking advantage of Groovy's metaprogramming capabilities brings great new possibilities that would be very difficult or just plain impossible to write with Java alone. Building Domain Specific Languages in Groovy is easy to do once a team has a good understanding of the Metaobject-Protocol (MOP) and the method dispatch mechanisms used by the Groovy runtime environment.

This session will cover in detail a number of advanced metaprogramming concepts in Groovy. The discussion will cover using dynamic method interception, meta-class manipulation, AST transformations and Groovy's Metaobject-Protocol (MP) to build flexible applications in Groovy including implementing a Domain Specific Language (DSL).

GORM is a super powerful ORM tool that makes ORM simple by leveraging the flexibility and expressiveness of a dynamic language like Groovy. With GORM developers get access to all of the power and flexibility of an ORM tool like Hibernate without any of the complexity.

This session will cover a lot of the GORM API from the developer's perspective as well as diving into some of the implementation details. Knowing how some of this works under the covers will give developers an opportunity to not only improve their productivity with GORM but also open up possibilities of using dynamic metaprogramming in other aspects of their application development efforts.

Groovy is an agile dynamic language for the Java platform. Groovy has a Java like syntax along with many features inspired by languages like Python, Ruby and Smalltalk.

This session covers a lot of ground including many interactive examples to highlight the powerful language features that make Groovy compelling. This session is aimed at Java developers who want to leverage the power of Groovy.

Grails is a super powerful framework for building applications for the Java platform. Grails addresses the pain points that the other web applications frameworks leave you with. This session covers the details you need to further extend Grails to help Grails help you in your environment.

Since 2006 Grails has had a really powerful and flexible plugin system. Much of the functionality in Grails itself is implemented as plugins. Grails makes it easy for you to further extend the framework to address needs in your environment. This session will detail how some of the core plugins work. The session will also cover all of the information needed to customize existing behavior or introduce whole new capabilities to the framework through the plugin system and other techniques.
