Gradle is being adopted by enterprises and open-source projects alike for its ease of use, flexibility, and compatibility with existing standards. However, Gradle's true strength shines not when it is viewed as a wrapper around standards, but as a toolkit for creating your own standards to reflect your build patterns and practices. It is extensible at every level, but most powerfully at the level of Gradle plugins.

In this session, you'll learn the Gradle APIs you need to know to develop a plugin, the different ways to organize and distribute plugins, and the way you should use plugins as a means of extending the Gradle DSL to describe your build domain in a concise and idiomatic way. Examples will use real code for a plugin written by Tim and Matthew that can be used in development and automated deployment settings.

Cassandra is a scalable, highly available, column-oriented data store in use at Facebook, Netflix, Twitter, Reddit, Rackspace, and a growing list of other deployments. It offers a compelling combination of a rich data model, a robust deployment track record, and a sound architecture—and it isn't just for web-scale operations. It might be a good fit for your Grails app!

In this session, we'll learn the basics of Cassandra, then look at how to use it for storing data in a simple Grails application. We'll work through a simple data modeling exercise and look at the code required for interfacing with this leading NoSQL solution.

The open source, and specifically, the Groovy, Grails, and Gradle communities are abuzz with the use of Git. But why? We'll take a anthropological look at the projects that have converted from Subversion to Git and why they decided to do so.

We'll examine the challenges and eventual successes of several Groovy and Spring project leads and their project migrations to Git. With projects such as Grails having two and a half years on the Git DVCS and Groovy recently converted, we'll dissect the more effective and social development techniques available to the core team and external contributors via Git. As a finale, we'll look at how these same Git benefits can be achieved on internal projects, or reflected back via contributions to open source Spring projects.

Java - Groovy integration just works, for most part. Calling into Java code from Groovy is pretty straight forward. Calling into Groovy from Java is easier than you may think (and that's the hard part!). There are a few rough edges you will run into when you try to call from Groovy into other languages.

In this presentation, we will take a look at integration mechanisms and how to work around the few challenges you may run into.

Multi-core processors have increased the demand to get concurrency right. Thankfully, the options for programming concurrency on the JVM has evolved from the JDK synchronize and suffer model to Software Transactional Memory and actor based concurrency.

In this presentation, we'll learn the reasons to go beyond the traditional JDK solution and how to make use of these two models from Groovy.

By Venkat Subramaniam

When I got into Java I had a "Wow, look how easy it is to implement these patterns." When I got into Groovy, I had the same reaction, but only better. The dynamic nature of Groovy makes it easier to implement some common patterns. What's better, there are some patterns that you can exploit in Groovy that are not so easy in Java. In this section, you will learn how to implement some traditional patters in Groovy, and also other patterns you are simply not used to in Java.

This presentation will go far beyond the Gang-of-four (GOF) patterns. You will learn how to implement some GOF patterns, but also some patterns that will allow you to exploit dynamic nature of Groovy and the elegance of Groovy closures.

By Venkat Subramaniam

Programming concurrency can be a pain or a pleasure depending on how you approach it. GPars is an elegant fluent library written with Java performance and Groovy conciseness and expressiveness in mind.

The latest major version of Groovy was released a few months ago, and it's time to have a closer look at what's inside!

This session will cover the improved Domain-Specific Language capabilities thanks to the command chain expressions. We'll move on to speak about the continued runtime performance improvement work to make Groovy the fastest dynamic language around. Then we'll see how more functional closures have become in this release, and we'll overview the built-in JSON support. And we'll review the most important AST transformations that have been added for removing even more boilerplate code from your code bases. And we'll finish with miscelanous coverage of improvements to the syntax, of improved and secured Groovy integration in your Java applications, and much more.

By Guillaume LaForge and Paul King

This talk examines how dynamic languages in general and Groovy in particular take us toward the goal of writing programs for a particular domain using phrases that look familiar to subject matter experts from that domain. Groovy, is a popular and successful dynamic language for the JVM. It offers many features that allow you to create embedded Domain Specific Languages(DSLs) including Closures, compile-time and run-time metaprogramming, command chain expressions, operator overloading, named arguments and other concise syntax conventions.

The talk highlights many of Groovy's DSL capabilities through numerous realistic examples. We'll give the example, explain the tricks used to implement the DSL, including any pros and cons as well as tackle the often forgotten but key aspects of readability vs complexity, testability, evolution, and the various considerations to keep in mind while designing DSLs.

By Guillaume LaForge

Guillaume will speak about Gaelyk, a lightweight Groovy toolkit for easily developing Groovy applications to be deployed on Google App Engine Java.

Grails represents technology that offers great flexibility and power without the complexity introduced by other Java web application frameworks.

Custom tag libraries are a snap. GSP Templates provide a simple mechanism for reusing UI elements. Sitemesh is integrated to help provide a consistent presentation across the entire application. GORM is super powerful ORM. Grails provides simple mechanisms for leveraging the power of Ajax.

By Jeff Brown

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 Meta Object 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, custom meta-class implementations and Groovy's Meta Object Protocol to build flexible applications in Groovy including implementing a Domain Specific Language (DSL).

By Jeff Brown

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.

We all know we should be writing functional (i.e. web) tests for our Grails applications, but this can sometimes seem like too much work for not enough gain. In this talk we'll look at the current Grails plugins that are out there that can start to decrease the development and maintenance cost and make getting the coverage you need more achievable.

Firstly we'll explore the powerful combination of Geb, the Groovy browser automation library, with Spock, the Enterprise ready testing framework, as the foundation for our testing stack. From there we'll discuss how to manage test data sets using the combination of the grails-fixtures and grails-build-test-data plugins. We'll then see how to use the grails-remote-control plugin to get inside your application from your functional tests to configure and how to use the grails-develop-functional-tests plugin to decrease the cycle time when writing your tests.

Finally, we'll discuss strategies for partitioning tests into logical groups and using the remote execution facilities of Geb to have you

So you already know and love Spock, the Enterprise ready testing framework, but want to know how to make the most of it and take your testing to the next level? Then this talk is for you. Even if you're new to Spock, but are interested in making your testing more effective this talk is for you.

We'll start with how the combination of Spock and the Groovy language makes it easy to bring the concept of “executable specifications” to the realm of unit testing, without the ceremony but with all of the benefits, and why this is so important to the health of your system.

From there we'll discuss extending Spock through its own Extension API and support for JUnit rules, which is one way to make your tests much more expressive and maintainable.

We'll close with Spock's seamless integration with Grails 2.0, and some hidden Spock treasures that help you get even more out of your testing.

Geb is a browser automation solution for Groovy. It brings together the power of WebDriver, the elegance of jQuery content selection, the robustness of Page Object modelling and the expressiveness of the Groovy language. Geb enables more expressive, more concise, and (very importantly) more maintainable web tests.

In this session we'll explore the foundations of Geb and illustrate how it uses the language features of Groovy to make web automation and testing productive and effective. After exploring the basics we'll explore Geb's rich Content DSL and discuss patterns for achieving maintainable tests. We'll also look at how it combines with Spock, the Enterprise ready testing framework, to enable low cost executable specifications that describe user behaviour, not browser details.

One hundred thousand messages per second, up-times measured in years, billions of dollars a day, operations in over 100 countries, hundreds of millions of users, that's enterprise!

Regardless of what you program in and at what scale you are going to come across some form of integration, at the simpler levels the frameworks take care of almost everything but as things get more complex old solutions can get cumbersome and new ones are needed, not restricted to Java but definitely Java-centric.

John will walk you through some more challenging integration architectures and a rather unique solution with a combination of Spring Integration and C24's Integration Objects. The solution adds powerful capabilities to Spring Integration such as SWIFT, a nasty banking standard used by the world's banking industry. The talk will include architecture, code and use-cases.

Now that HTML5 is the standard output format for Grails 2.0, shouldn't you really dig in and see what all of the excitement is about?

HTML 5 offers dramatic new improvements for page organization, offering out-of-the-box support for elements like header, footer, nav, section, and article. HTML 5 adds native support for form features such as placeholder text, autocomplete, autofocus, and validation. Additionally, there are a host of new form elements available (email, url, number, range, date, and search) that gracefully degrade in "classic" web browsers - IE, I'm looking at you!

In this talk, you won't be subjected to discussions about the features that will appear in some distant future release of a web browser. Instead, you'll see the HTML 5 features that are already being used by Google, Apple, and others. You'll see the features that are supported by today's browsers, ready for you to use right now.

It always amazes me when Groovy developers say, "I don't like JavaScript." Both are dynamic languages that make metaprogramming seamless, but Groovy edges out JavaScript in the race for conciseness and syntactic sugar. That is, until CoffeeScript came onto the scene.

CoffeeScript is to JavaScript as Groovy is to Java -- both give their respective base languages a thoroughly modern makeover. CoffeeScript brings string interpolation (think GStrings), null-safe property access (person?.middleName and our beloved Elvis operator), and much more to JavaScript development. Perhaps CoffeeScript founder Jeremy Ashkenas says it best: "Underneath all of those embarrassing braces and semicolons, JavaScript has always had a gorgeous object model at its heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way."

CoffeeScript is more than an intellectual curiosity. It is the #1 most followed project on GitHub. It ships as a standard library in Rails 3.1. But most importantly, Brendan Eich openly acknowledges that CoffeeScript is influencing the future direction JavaScript (formally, ECMAScript "Harmony"). Much of what you see in CoffeeScript today will become native to JavaScript tomorrow.

Why don't you join me and see what the fuss is all about? You'll never look at JavaScript the same way again.

Spring always provided sophisticated support for various data access technologies. The lately coined Spring Data project now takes the next step and introduces support for non-relational data stores like MongoDB, CouchDB, Cassandra, Redis and Riak just to name a few.

Beyond that it helps implementing data access layers in a consistent and easy-to grasp fashion, for both the NoSQL stores as well as more traditional APIs like JPA. The talk introduces the umbrella project, foundational concepts and abstractions and dives down into specialties of particular modules hands-on.

By Oliver Gierke

Domain driven design has become a ubiquitous approach to tackle complex problem domains and build a rich object model. Furthermore JPA has become the standard and widely accepted way of object persistence in the Java world.

The talk introduces the the Spring Data project in general with a focus on the JPA module that allows developers to easily implement JPA based repositories in a sophisticated way. We start with a brief analysis of a plain JPA based repository implementation and outline pain points esp. regarding the domain driven approach (lack of abstraction, tediousness of executing queries, pagination and so on). The main part of the talk then takes a look at how Spring Data JPA provides solutions to those problems.

By Oliver Gierke

If applications grow bigger, modularity becomes a key aspect regarding maintainability. Design decisions made in the early days are hardly discoverable in the codebase, inter-module dependencies grow a lot.

The talk introduces means and approaches to connect logical architecture to the codebase. Beyond that we discuss patterns and best practices around general code organization, package structures to build a solid foundation for Java applications and in how far Spring can help creating loosely coupled components and dedicated points to extend applications.

The web has gone through periods of experimentation, stagnation, revolution, and evolution to bring us to the state we are in today. The browser vendors are once again innovating at breakneck speed while still keeping an aggressive eye towards standardization, and as web developers we have an amazing array of tools at our disposal whether developing for desktop, mobile, or any other of the emerging form factors where a modern performant browser is available. Many things that were once thought "impossible" to build with open web tools are becoming today's reality on the web.

This session will examine the techniques being applied today to create large single-page web applications. Through diving into the architecture of an in-browser IDE and other such "impossible" web applications, topics that will be covered include:

New browser facilities that can be utilized today and effective ways to experiment with what is yet-to-come

Modular approaches to building and maintaining the front-end code for large in-browser applications

Composition of small, specialized, loosely-coupled server-side modules to form a complete system

With the increasing popularity of both cloud computing and polyglot programming, more and more developers are working in environments that are both multi-language and multi-platform. Of course, with many languages and many different deployment contexts, communication between system components can be problematic. Efficient communication between components requires agreement on payload formats, communication protocols and, for developer sanity, sophisticated language bindings. Thankfully, messaging systems such as RabbitMQ provide the perfect solution. RabbitMQ is a popular, open-source, multi-protocol messaging broker with bindings for many popular languages.

In this talk, Rob Harrop, a senior RabbitMQ team member, will explore some of the options that RabbitMQ provides for multi-platform messaging. Attendees will learn how to access RabbitMQ from a variety of languages including Java, Python, Ruby and Erlang, using different protocols including AMQP and STOMP, and from different environments, including in-browser messaging using WebSockets.

Spring Data Graph is an integration library for the open source graph database Neo4j and has been around for over a year, evolving from its infancy as brainchild of Rod Johnson and Emil Eifrem. It supports transparent AspectJ based POJO to Graph Mapping, a Neo4jTemplate API and extensive support for Spring Data Repositories. It can work with an embedded graph database or with the standalone Neo4j Server.

The session starts with a short introduction to graph databases. Following that, the different approaches using Spring Data Graph are explored in the Cineasts.net web-app, a social movie database which is also the application of the tutorial in the Spring Data Graph Guidebook. The session will also cover creating a green-field project using the Spring Roo Addon for Spring Data Graph and deploying the App to CloudFoundry.

Grails is often considered just a quick simple web application development framework. But the truth is it is much more.

This presentation will take a Grails developer beyond 'grails generate-all' to understand how to create a maintainable, secured and high performance grails application for your enterprise.

By Mark Johnson

The factory patterns and callbacks have been around for a long time as a technique to provide flavor specific code variations. But they are awkward and hard to update. Enter Groovy closures. Imagine having the ability to inject different coding flavors using code closures. If you need a different flavor, then just pass a different code block. Now imagine that all of this works on the JVM!

This session will use hands on examples to explore how to use and create closures. In addition, during the discussion we will also discuss when it is appropriate and inappropriate to use closures in your applications.

Spring Insight provides trace data for web-container managed threads out of the box. But, what about other application threads? Fortunately, Insight provides a pluggable architecture for enhancing the standard trace capabilities. This session discusses the use of the annotation plugin to immediately obtain valuable trace data without writing any additional code. It goes on to to describe the more advanced technique of creating a custom plugin and takes a deep dive into the new Spring Integration and JMS plugins. Finally, we discuss how you can get involved by contributing your own plugins to the community.

Groovy 1.9 includes a brand new modularisation feature which allows Groovy to be split into smaller pieces. This mechanism allows us to package up Groovy for different contexts (think enterprise servers, desktops, netbooks and phones) but also to evolve Groovy over time. It also allows module writers greater power in terms of being able to leverage many of the Groovy run-time and compile-time internal features.

This talk looks at these modularisation features including defining modules, module metadata, adding meta-programming features, integration hooks and more. We will also build our own "hello world" module from scratch.

By Paul King

This talk looks at using Groovy for writing multi-threaded, concurrent and parallel programs. We'll briefly look at leveraging legacy Java techniques such as multiple processes, multiple threads, the java.util.concurrent APIs and shared-state atomicity.

We'll then look as some useful AST transforms in core Groovy (Lazy, Synchronized, Immutable, WithReadLock and WithWriteLock) before divign headlong into GPars. GPars is a comprehensive library for parallel execution that provides a menu of options to the developer.

The different choices available have pros and cons depending on the circumstances. We'll look at the parallel collection support and the optional transparent way to use that support. Then we'll examine Map/Reduce. We'll also look at the DataFlow approach to achieving concurrency, the Actors approach, the use of composable asynchronous functions and the use of Agents and Active Objects.

Finally, we'll peek at Multiverse (Software Transactional Memory) and JCSP, two emerging approaches that might appear more prominently in future versions of GPars. Then we'll wrap up with a brief look at testing multi-threaded programs.

Over the years we have seen many debates about how best to write and maintain our programs. Should we use OO or functional? Should we use sequential or concurrent? Should we use static or dynamic typing? What design patterns should we use (or anti-patterns should we avoid)? What can we learn from the strengths and weaknesses of the many languages that are now available for us to program in?

In this talk, we give numerous examples which highlight the different ways to code and test our programs. It looks at the trade-offs that different typing and coding styles give you in terms of a number of features including: ease of reading and writing, tool support, ability to modify, ability to make concurrent, ability to test and a number of other criteria. The talk doesn't attempt to provide a single answer to what is the best one true way to code all programs but gives you many examples to ponder and many context-dependent guidelines for you to factor in to your choices.

Grails object relational mapping (GORM) is one of the most powerful features of the Grails framework. Project bootstrapping and CRUD scaffolding are nice things to get you started, but GORM continues to pay off throughout the development of an application. Even maintenance tasks become simpler and more fun with GORM. Now, with Grails 2, GORM has become more powerful and easy to use than ever.

In this presentation we’ll discover what GORM is and what it does for us. We’ll cover dynamic domain class methods, dynamic finders, one-to-many and many-to-many relationships, Hibernate Criteria Builders, new Grails 2 Where Queries, and more. We’ll also take a look at some things to watch out for since, after all, this is Object Relational Mapping we’re talking about.

You and your team know Java well and you have invested much to get there. But there are places in any Java project where you have to leave your preferred language to get things done: for build automation, modeling complex business domains, smart configuration, user macros, office integration, ad-hoc inspections, and more.

This session presents seven patterns on how you can leverage your Java knowledge in these areas with the help of the Groovy extension language. The seven patterns are easily remembered by their names: Super Glue, Liquid Heart, Lipstick, Keyhole Surgery, Unlimited Openness, Ghost Writer, House Elf. If you love Java and would like to see it used everywhere in your project, you will find new opportunities here.

Groovy and the Spring framework are old friends. Spring includes dynamic beans that can be modified while a system is still running, and of course the Grails framework is built on top of Spring MVC. Here we'll illustrate all the ways that Groovy works with Spring, and show how a developer can take advantage of those capabilities right away.

Examples will include using Groovy beans in Spring systems, refreshable beans, inline scripted beans, aspects in Groovy, and even the Grails Spring bean builder.

2011 is turning into a tremendously exciting year for Grails developers. One of the most important developments is the arrival of several new cloud hosting providers that work with Grails applications with minimal effort on your part. No longer do we have to look enviously at our Rails comrades who have Heroku et al.

The new batch of solutions are known as Platforms as a Service (PaaS), so this talk will first explain what this means before delving into the individual providers. You'll be able to compare what each provider offers and see how the Grails integration compares as well.

The motivation is to demonstrate how to use some of the numerous extensibility planes in the Spring framework to adapt the framework to your particular needs. Spring provides numerous SPIs for just this sort of thing. Need to handle batch processing against a custom source? Write a Spring Batch ItemSource. Want to listen for events in an external system? Write a Spring Integration adapter. Want to work with a new, transactional resource? Implement a PlatformTransactionManager. Want to render custom Spring MVC views? Implement the Spring MVC View. Want to talk to a custom RESTful endpoint? Implement an HttpMessageConverter. In this talk, Josh explores some of the powerful components that - while useful, were designed to be extended.

Relational databases have long been considered the one true way to persist enterprise data. But today, NoSQL databases are emerging as a viable alternative for many applications. They can simplify the persistence of complex data models and offer significantly better scalability, and performance. But using NoSQL databases is very different than the ACID/SQL/JDBC/JPA world that we have become accustomed to. They have different and unfamiliar APIs and a very different and usually limited transaction model. In this presentation, we describe some popular NoSQL databases – Redis, and MongoDB. You will learn about each database’s data model and Java API. We describe the benefits and drawbacks with using NoSQL databases. Finally, you will learn how the Spring Data project simplifies the development of Java applications that use NoSQL databases.

Application and platform security requirements are changing under the influence of standards like OpenID and OAuth2, and the increasing demand for lightweight and multi-language platforms. Everyone used to be happy if they could implement single sign on for their Java web applications. That's still important, but there is a growing demand for more extensive Identity Management services, both in the enterprise and for public web applications. CloudFoundry is a nice use case for this new service model: it has multi-language support and security requiements that go beyond simple single sign on. What does that mean, and what does it mean for Spring Security? Come to this presentation to find out.

Garbage Collection is an integral part of application behavior on Java platforms, yet it is often misunderstood. As such, it is important for Java developers to understand the actions you can take in selecting and tuning collector mechanisms, as well as in your application architecture choices. In this session, Gil Tene (CTO, Azul Systems) will review and classify the various garbage collectors and collection techniques available in JVMs today. Following a quick overview of common garbage collection techniques including generational, parallel, stop-the-world, incremental, concurrent and mostly-concurrent algorithms, we will define terms and metrics common to all collectors. We will classify each major JVM collector's mechanisms and characteristics and discuss the tradeoffs involved in balancing requirements for responsiveness, throughput, space, and available memory across varying scale levels. We will conclude with some pitfalls, common misconceptions, and "myths" around garbage collection behavior, as well as examples of how some good choices can result in impressive application behavior.
