7:30-8:30: Vagrant: For the Weird and Strange by Andy Ennamorato.

The Java write once, runs everywhere dream is still alive…right? When it’s not (or when you just want a clean environment to develop and test in), you might take advantage of Vagrant, an open source project that helps bring a repeatable process to your development environment. This introduction to Vagrant will introduce you to the basics of using development virtual machines and give you just enough info to be dangerous. Or weird and strange, your choice.

About Andy Ennamorato:

Andy Ennamorato, aka @virtualandy, hails from Denver by way of Flori-duh. He can be found in the deep dark basements of Buckley AFB where he works, or at many of the local tech meetups in the area when he’s not at home with his wife and son. Chat with him about baseball, technology, beer or sushi and you’ll have a laughing good time.

6:10-6:55: Drop the angled brackets. Discover the zen of writing (Ascii)Docs. – Dan Allen
Writing documentation is already hard enough. Why do we make it harder by burying the content in an XML schema like DocBook or wrestling with finicky WSYWIG editors? Come learn how to find the zen of writing documentation using AsciiDoc and still be able to produce beautiful HTML 5, DocBook and PDF documents–or even a slide deck like the one in this presentation!

7:15-8:30: Reducing Java Enterprise Testing to Child’s Play – Dan Allen

This talk unveils the missing link in enterprise Java development: simple, portable integration tests. For many, working in enterprise Java has long been an arduous undertaking because of this void. While development life is simple with unit tests and mocks, they only take you so far. Eventually, you need to validate how your components interact and operate in their intended environment–you real need integration tests. Yet, writing integration tests has meant assuming the burden of bootstrapping all or part of your infrastructure. That’s time lost and it places a mental barrier on testing. Arquillian and ShrinkWrap, two new projects from the JBoss Community, partner to tear down this barrier and reduce Java enterprise testing to child’s play. Come experience how.

Arquillian, a container-oriented testing framework layered atop TestNG and JUnit, brings your test to the runtime rather than requiring you to manage the runtime from your test. Picking up where unit tests leave off, Arquillian enables you to test real components that rely on real enterprise services in a real runtime.

We’ll look at how the fluent API provided by ShrinkWrap is used to package a test archive, giving developers fine-grained control over which resources are available to be tested. We’ll show examples of how the test archive is deployed and executed inside standalone, embedded and remote containers. You’ll witness how RPC-style (or local, if applicable) communication between the test runner and the environment negotiates which tests are executed and reports back the results. You’ll walk away confident that you can write integration tests just as you would a unit test and the test is portable to multiple environments (containers).

What’s the secret? This talk reveals how Arquillian simplifies integration testing by providing a component model for tests, just as Java EE 5 simplified server-side programming by providing declarative services for application components. The test component model consists of container lifecycle management, test enrichment (dependency injection), container deployment and in-container test execution. Using a component model means your tests are portable and able to move between different environments, from single embedded or remote to multi-server to multi-cloud nodes.

About Dan Allen:

As Principal Software Engineer at Red Hat, Dan serves as the JBoss Community liaison, leads the JBoss Testing Initiative and is a member of the Arquillian, ShrinkWrap and JBoss Forge projects. He authored Seam in Action (Manning), served as a representative for Red Hat on the JSR-314 Expert Group (JSF 2.0), writes for IBM developerWorks and NFJS magazine and is an internationally recognized speaker. He’s appeared at major industry conferences including JavaOne, Devoxx, NFJS, JAX and Jazoon and has received recognition as a JavaOne Rock Star, a JBossWorld Top Presenter and a JAX Hall of Fame speaker.

To colleagues, Dan’s known for his hard work and passion for Open Source technologies. His technical expertise includes Java frameworks (Seam, CDI, Weld, JSF, EJB 3, JPA, Hibernate, Spring), testing frameworks (Arquillian, JUnit, TestNG, Selenium), build tools (Maven 2, Gradle, Ant) and web development (Ajax, JavaScript, CSS) and more.

6:10-6:55: Spring Insight, What Just happened? by Derek Beauregard

Spring Insight answers the question “What just happened?” (in my web application). It is a free SpringSource Web application that gives you real-time visibility into application behavior and performance.
In development and testing stages, developers can use Spring Insight to verify immediately whether their newly-written code is behaving as designed. QA engineers can pinpoint specific causes for “what just happened” and relay detailed information to developers.
Stress testing an application typically tells you which URL areas are slow. By combining Spring Insight with your existing tools (such as JMeter), you can see not only which URLs are slow, but why, thus accelerating your time to production.
All of this is done through automatic, no configuration and zero coding, code introspection that works with the Spring Framework, Spring MVC, JPA, Hibernate and more. And its extensible, so you can build your own adaptors for your technology.

About Derek Beauregard:

Derek Beauregard is a technologist at heart with over 10 years experience in the industry. He is currently working as a Sales Engineer in the vFabric (Spring Source) division of VMware. Prior to this role he was a consultant in the vFabric PSO organization designing and implementing vFabric/Spring based solutions for VMware’s customers across multiple verticals. His work has concentrated lately on Application Modernization, Platform as a Service (PaaS), and Big/Fast/Flexible data. Derek is based out of Denver, CO.

MAIN PRESENTATION: Functional Thinking by Neal Ford

Learning the syntax of a new language is easy, but learning to think under a different paradigm is hard. This session helps you transition from a Java writing imperative programmer to a functional programmer, using Java, Clojure and Scala for examples. This session takes common topics from imperative languages and looks at alternative ways of solving those problems in functional languages. As a Java developer, you know how to achieve code-reuse via mechanisms like inheritance and polymorphism. Code reuse is possible in functional languages as well, using high-order functions, composition, and multi-methods. I take a variety of common practices in OOP languages and show the corresponding mechanisms in functional languages. Expect your mind to be bent, but you’ll leave with a much better understanding of both the syntax and semantics of functional languages.

About Neal Ford:

BASIC CONCEPTS: JMX by Jason Brown

Do you know what your service is up to? If you have critical services running in a data center or your basement, you need a way to keep an eye on them. JMX provides an easy way for your services to expose their state, allow monitoring tools to inquire about that state, and provide hooks for management tools to perform operations on the service.
