Arquillian Abstract:
In this session, Andrew Rubinger will 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 that 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.

In this session, Andrew will 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
Attend this talk to learn how the simplified component model of Java EE can be applied to testable development.

We have three presentations scheduled coming up.

On June 21st we will have Andrew Rubinger from JBoss will talk about Arquillian, an integration testing framework.

On July 19th, Jeff Schwartz will talk about a new Java framework called Play.

On August 23, local developer Igor Polevoy will talk about his framework called ActiveWeb. He spoke last year about ActiveJDBC, his Java implementation of Active Record.

For our May 17th Meeting, Cedrick Johnson will discuss integrating the R Statistical Environment and Java integration.

There are currently several packages in R for integrating the two (rJava and RServe). This presentation focuses on using R to perform statistically “heavy” calculations and interaction within a Java environment (in this instance using JMS as the underlying message bus to pass messages from Java applications to the RServe instance). It is particularly useful in the financial domain, although there could be applications outside of the financial domain.

Mr. Johnson has over 10 years experience in technology, the past 8 years focused on financial markets (equity derivatives, fixed income). His focus has been on quantitative trading systems using Java, C# and R in various distributed, highly fault-tolerant environments for a former Big 5 investment bank and some of the leading market-making and small to midsize private asset management firms. He currently resides in Chicago as of 2008 and spends his spare time blogging about the fusion of technology and fixed income markets.

Our April meeting will be on April 19th. Jeff Palmer of CGUG will talk about Groovy on Grails.

This talk will give a brief introduction to Grails. The goal of the talk is to help users get started and productive with Grails. The talk will demonstrate how to build a Grails app from start to finish. It will cover most of the core Grails components, including domain classes, controllers, scaffolding, GSP tags, GORM, services, Grails JavaScript and Ajax support, and URL mapping.

Groovy is a dynamic language that runs on the JVM. Grails is a web application framework written in Groovy that uses “convention over configuration” to build web applications quickly.

Jeff Palmer is an application developer for Follett Higher Education Group. Jeff has a MS in Computer Science from DePaul University and is a Sun certified Java 5 programmer. For the last three years he has been actively focused on alternative JVM languages, such as Groovy and Ruby, along with their respective web frameworks, Grails and Rails. Jeff is a co-founder of the Chicago Groovy User Group.

Java EE6 – What’s New, What’s Cool…What Matters?

I would like to keep this session highly interactive – starting with a fundamental question: ‘Do EE standards matter to us that much any more or are we more interested in what makes our jobs easier?’

From there we will look at what is new in EE6 and how it helps us as developers write not only better applications, but also more maintainable code as well as (hopefully) increase developer productivity. In particular we will consider the following topics:

• Servlet 3.0
• JPA 2.0
• JSF2
• Validators
• EJB3.1 (yes, I know we are still scarred from EJB2 – trust me this is substantially better)
• CDI
• RESTful services

We will cover all of the above topics with at least an overview, and vote in the group which ones to dive deeper into with code, etc.
