November 1st Meeting - Evolving JavaServer Faces

Java Web Development, you've come a long way baby!

From raw Servlet programming emitting HTML markup, to Struts 1.x, to JavaServer Faces (JSF) 1.x, Java really did advance the ball for producing enterprise-grade web applications.

JavaServer Faces became the official Java Enterprise Edition web framework and was baked into JEE5. It has evolved into JSF 2.x which is the standard web framework fro JavaEE 6.

JavaServer Faces 2.x has moved the Java web development ball even further downfield, simplifying many of the tasks developers need to do to create web applications in Java.

In this presentation, I'll walk you through the basics of JavaServer Faces development, providing an overview of the JSF Request Life-cycle and artifacts used in JSF.  We'll then take a JSF 1.x application and apply the JSF 2.x features to reduce configuration and a lot of the high ceremony code needed in JSF 1.x.

We'll then go a step farther and apply Groovy code in those places allowed in JSF 2.x (and there are many!), to whittle down the codee even more.

When we're done, the final JSF application will do everything it did before, but with a fraction of the code and configuration needed in JSF 1.x.

Don't worry if you're not familiar with JSF or using it JSF now. This presentation is for Java developers doing any web development who would like to see how JSF works, both in v 1.x and 2.x. It's also for Groovy developers looking for a way to apply their Groovy skills in enterprises already doing Java web development. While no prior JSF experience is necessary, experienced JSF developers will enjoy witnessing the evolution of JavaServer Faces!

Here's what we'll cover:

• JavaServer Faces - The Basics
• JSF 1.x Sample Application Code Review
• Morphing a JSF 1.x App into a JSF 2.x App
• Making JSF Groovy

So tell your friends and come on out to network, learn some JSF, and generally have a good time! As always, we'll have good food and drinks, and valuable door prizes!

NOTE: This presentation will be for both the Gateway JUG and Gateway Groovy Users Groups as both Java and Groovy topics will be covered.

Oct 4 JUG Meeting: Change Anything with Cucumber and ATDD

 
Alright, so you’ve heard the TDD claim to fame.  Your code (…. Your functionality) is closely protected by an ever vigilant suite of tests ready to stop bugs before they are even introduced.  This sounds good, eh?

While TDD and unit testing provide numerous advantages in addition to protecting existing functionality, one shortcoming you may discover is that the scope of the unit test is too small.  Yeah, it tests how that individual class works,  but will it test the application as a whole?  Furthermore, will my unit test even be useful after a big change to the class structure?  Not likely.

Enter Acceptance Test Driven Development using Cucumber.  Test the whole application, nothing but the application, and only the application.  Allow yourself to be free to change big things and still have absolute confidence that your application still performs.  Furthermore, doing ATDD with Cucumber allows your tests to be in English (or Swedish if you like).

Whoa.  Tests in English!?  That sounds like a bad idea…  You have to see it to believe it.  It’s DRY and it’s awesome.  See you October 4^th.

Sept 6 Meeting - Concurrency in Java

 

The Concurrency in Java presentation will be a straight to the point design and
coding experience.

We'll dive into the most common problems like deadlocks,
starvation, live locks and race conditions. We'll discuss what causes them
and what patterns we can use to avoid them. We'll examine what anti patterns
can be found in existing code and how to fix them. We'll review immutable,
atomic and concurrent objects as well as synchronization. Last, but not
least, we'll see some API offered by JDK to help us write elegant code that
executes correctly in multi-threaded environment.

August 2nd Meeting - JSR 299: Contexts & Dependency Injection

JSR 299: Contexts & Dependency Injection

In August, we'll explore JSR 299, Contexts & Dependency Injection.

If you've been working with Spring, you can appreciate the flexibility offered by Dependency Injection and Aspect Oriented Programming (AOP). However, robust dependency injection was not available in "out-of-the-box" in the Java Enterprise Edition (JEE) until JEE 6. This capability was defined in JSR-299, once called "Web Beans", but now named Contexts & Dependency Injection (CDI).

In this presentation, we will explore the capabilities offered by CDI, not only in JEE 6, but in a servlet container (i.e. Tomcat) and even in plain ol' Java SE. Specifcially, we will discuss:

• About JSR 299
• CDI Objectives
• Relationship to Other Specs
• Sounds a Lot Like Spring …
• CDI Availability
• CDI By Example
  • CDI In Java SE
  • Producer Methods
  • Interceptors
  • Decorators
  • Events
  • Stereotypes
  • Specialization, Inheritance and Alternatives
  • Working with JEE Resources
  • JEE Integration
  • CDI In Tomcat (with JSF 2 examples)

When you leave, you should have a good idea of what role CDI can play in your current and future projects.
