• Building Mobile Apps with HTML, PhoneGap and Java

    Wednesday April, 11, 2012 11:00 PM

    HTML has emerged as a powerful alternative to “native” and enables cross-platform mobile application development. 


    In this session, you will learn modern strategies to build complex and native-like mobile applications using HTML and JavaScript, and powered by a Java back-end.


    You will also learn how to build a RESTful API using JAX-RS and Spring, how to efficiently consume REST services and structure large JavaScript projects using an MVC framework like Backbone.js, and how to use PhoneGap to leverage the capabilities of your device (camera, gps, accelerometer, etc.) in JavaScript, and package your HTML application as a native app for distribution through the different app stores.

  • Learning Scala by Example: walking through the rewrite of a small Open Source Project

    Wednesday March, 07, 2012 11:00 PM

    The best way to learn a new language is to use it, but there is an enormous gap between HelloWorld.scala and a "real" project. To help with my own learning of Scala I rewrote my Log4JFugue Open Source project which at about 2500 lines of code was big enough to be real yet small enough to be manageable. We will briefly describe the problem space addressed by Log4JFugue, then summarize the architecture of the Java version. The majority of the night will be a hands-on, code-on-the-fly recreation of the Scala version from scratch. You will see the differences between the languages and get a feel for coding in the functional paradigm. No background in Scala is required.

  • Getting started with MongoDB

    Wednesday February, 08, 2012 11:00 PM

    What is MongoDB, why would you use it, how do get started and what are the "gotcha's" to look out for? We'll start with a very brief survey of NoSQL data stores, then we'll dig into why you'd consider using Mongo and how to get started with it.


  • What's new with Grails 2.0

    Wednesday January, 11, 2012 11:00 PM

    This session will include an introduction to the Grails dynamic web application framework and the Groovy language, with highlights from the new features in Grails 2.0 (including agent-based reloading, unit testing mix-ins, and new enhancements to support Servlet 3.0) and Groovy 1.8. We'll also go beyond the basics and demonstrate real-world usage of Grails while live-coding a working Grails application from scratch using Spring, Hibernate, JMS, and other technologies to demonstrate how quickly you can develop Java EE applications in Grails.


  • Inside Android's Dalvik VM

    Wednesday November, 09, 2011 11:00 PM

    In this presentation, Doug Hawkins will discuss how the Dalvik VM is different from traditional Java VMs and the motivations behind those differences. Along the way, you'll learn about Android's service architecture, Dalvik's byte code format, and the surprising details of how Android installs, launches, and executes applications.


  • Testable Enterprise Development in Java

    Wednesday October, 12, 2011 11:00 PM

    In this session, we'll address the missing link in Enterprise Java development: simple, easy integration testing.

    Unit tests and mock objects will only take you so far; the only answer which truly ensures that all components are playing nicely is a comprehensive integration suite. Unfortunately, writing integration tests has historically involved manual setup of a heavy, cumbersome test harness. That's time lost, but it doesn't have to be anymore.

    Here we'll introduce Arquillian, a powerful container-oriented testing framework layered atop TestNG and JUnit. Arquillian manages your runtime, abstracting out deployment and allowing you to focus on real test logic. We'll cover:

    * Transparent container lifecycle management
    * Declarative deployments
    * Test Enrichment (Dependency injection into tests)
    * In-container test execution

    All examples will be powered by the new lean offering from the JBoss Community: Application Server 7. Attend this talk to learn how the simplified component model of Java EE can be applied to testable development.

  • 90 Minutes to a working Enterprise Application! or Development is more than just a fancy programming language!

    Wednesday September, 07, 2011 11:00 PM

    We have all heard use this language or that framework or this product and you can create the perfect enterprise application. After all these years do you still believe that? The truth is to produce a successful enterprise application we need to have a solid development language, frameworks, lightweight containers, monitoring through the application life cycle and infrastructure stack, plus plans to manage application performance. In short there is a lot we need to do after passing the first round of unit tests to create a sucessful enterprise application.

    This session will use a series of live demos to go through the entire Application Lifecycle to demonstrate often ignored steps to produce an enterprise application. The concepts covered in this presentation are applicable with most technologies; but for our purposes we will focus on Spring ROO & Grails, Hyperic for monitoring, Tomcat 7 for the container, Webtest for functional testing, Cobertura for code coverage, plus a few other technologies.


  • Functional Thinking

    Wednesday August, 10, 2011 11:00 PM

    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 langauges 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.

  • Multi-Topic Night - NEJUG Members presenting areas of their expertise

    Wednesday June, 08, 2011 11:00 PM

    This is the promised members presentation night we have been waiting for over the last year.In this meeting you will be able to cover 5 different topics from actual day to day practioners of their topics. We have seen time after time that some of the best presentations over the past 10 years have come from our very own members who use these technologies every day.

    Topics which will be covered include:

    • Hazelcast
    • Schema Crawler
    • The Strangler Pattern for incremental application migrations
    • Understanding Open Standards: Open Standards : OpenSocial, OpenID, OAuth, Oh my
    • BDD (Behavior Driven Development)

  • What Functional Purists don't want you to know about Scala

    Wednesday May, 11, 2011 11:00 PM

    Scala is a JVM programming language that blends object-oriented and functional concepts. We are all well familiar with the object-oriented aspect but lot of us seem to struggle when it comes to functional programming. Unfortunately, a large number of Scala talks and articles present functional programming in a way it just makes your brain hurt. You start believing only math-minded can truly comprehend it. Furthermore, you get an impression Scala is only a good fit for problems which need to be solved in a pure functional style. All of which is, fortunately, far from being true.
