A practical introduction to Java EE 6
During this workshop you will get a complete overview of Java EE 6. You will learn to develop web applications and RESTful web services using CDI, JSF, EJB, JAX-RS and JPA. We will add integration tests to the code using Arquillian. We will also discuss some architectural patterns and setup a project that can be build on a CI server. During the workshop we will mix theory and hands-on, you will write a complete application yourself.

Mastering Continuous Integration with Jenkins
Students will come away from this workshop with a solid understanding of how to implement a Continuous Integration environment in their organization. They will be able to set up a working instance of Jenkins server, complete with automated builds, tests, code quality audits and reports, and automatic deployment to an integration server. They will also be able to integrate Jenkins with other tools in the development environment, such as issue tracking systems and source code browsers.

13.30-16.30
Rediscovering Modularity with Restructure101
The principles of modularity are applied routinely in the development of classes, but not to the organization of the classes themselves. This is unscalable; inevitably it will extract a big tax on development dollars as the team starts to drown in an ever-expanding sea of classes. This tutorial gives concrete strategies for constructing a hierarchical, levelized, modular structure for an existing code-base, with minimal impact on working code. Many pattern-action-result examples are given.

Up up and Out: Scaling software with Akka 2
Akka is a unified runtime and programming model for scaling both UP (utilizing multi-core processors) and OUT (utilizing the grid/cloud). With Akka 2 this will be taken to a whole new level with its “Distributed by Design”. Akka 2 provides location transparency by abstracting away both these tangents of scalability by turning them into an operations and configuration task. In this talk you will learn what Akka is and how it can be used to solve hard scalability problems. http://akka.io

Kotlin: Making the Java Platform a Better Place
Kotlin is a modern statically typed general-purpose language designed to be safe, concise, expressive and 100% Java-compatible. It is compiled to Java byte code as well as JavaScript, so it can run on both client- and server-side.
This session gives an overview of the key features of Kotlin and demonstrates how the new language integrates into the existing infrastructure. On top of that we show how one can make Java APIs better using Kotlin, without having to alter them in any way.

The Art of Metaprogramming in Java
Metaprogramming is the dirty little secret behind the success of many Java frameworks such as Spring and Struts2, and forms the backbone of many of the most fundamental APIs across the JEE technology stack. This session aims to introduce the topic and highlight, with code examples, the different mechanisms and techniques to take advantage of this underused feature of the Java Programming Language. This session will adopt a learn-by-example approach that combines the theory with concrete code.

Git on Android: Spreading Rebellion
A distributed version control system lets projects spread like fire in dry grass- and if the aim is to make the flame spread, it should be able to reach even the device resting in your pocket. Developing a Git client for Android threw up a bunch of interesting challenges; from low-level bug-hunting in the source of Android to unusual UI tricks. This talk describes those challenges, the curious bugs found, and the resulting Grand Tour of open-source projects; patching Android and even Git itself.

Modern enterprise application configuration with Spring
The Spring family projects have long been important tools in the enterprise Java developer's toolkit. Often though, Spring is characterized as being too dependent on XML. This session will take a deep look at how Java applications can be configured entirely in code, eliminating Spring-, JPA- and even Servlet-related XML. We'll also look beyond the core Spring Framework and explore how higher-level Spring projects like Spring Data and Spring Integration take advantage of code based configuration.

He is a frequent speaker at conferences around the world and is @cbeams at Twitter and GitHub.
13.00-13.50
Maven vs Gradle, On your marks, get set, go!
Ant, Maven, Gradle, Buildr - the choice of built systems for Java based systems is manifold and only discussions about coding styles are getting more heated than discussion on which built system is superior. In this talk we are looking at two built system - the well established veteran Maven against the Groovy based newcomer Gradle. Where are the similarities between these two built systems and what differentiates them? Why and when would you chose one over the other?

Polyglot Programming in the JVM
The JVM boasts one of the biggest software ecosystems: you will find libraries, components and servers of all sizes, types, colors and flavors; which have made it the choice language for many. However the JVM is open enough to let other languages live in it, these languages provide new features and concepts that the Java language does not have. On this session we'll discover the benefits of adding a bit of spice to your Java development skills by exploring Groovy, Scala and Clojure.

How RESTful Is Your REST?
The rise of Mobile and the diversity its technologies make exposing a RESTfull API the most crucial capability of any application and the key to its success. In the absence of widely adopted best practices and well-defined conventions, designing such an API is nothing but trivial. This presentation introduces the fundamentals of REST architecture, and discusses the principles of RESTfull design.

Retrofitting a software architecture to an existing code-base
We can do without architecture early on, but at some point a clearly communicated architecture offers big productivity benefits to developers who otherwise drown in the expanding implementation-level detail. When you realize you are heading for a Big Ball of Mud, you have 3 choices – start over, suffer on, or knock your codebase into shape. This talk outlines principles, options and examples using Structure101 to get the best return for the cost and intellectual effort invested in a codebase.

Lambdas in Java SE 8 or co-evolving libraries, the language and the VM
Lambdas is going to be the biggest new feature in Java SE 8. This presentation will show you the need for lambdas, the feature in itself, and also how adding lambdas to Java makes makes it necessary to solve the problem of library evolution. Also you get to see how lambda expressions, type inference, default methods and library improvements makes parallelism much easier to express.

Nashorn: Optimizing JavaScript and dynamic language execution on the JVM
There are many implementations of JavaScript, meant to run either on the JVM or standalone as native code. Both approaches have their respective pros and cons. The soon-to-be open sourced Oracle Nashorn JavaScript project is based on the former approach. This presentation goes through the performance work that has gone on in Oracle’s Nashorn JavaScript project to date in order to make JavaScript-to-bytecode generation for execution on the JVM feasible.
