6:30 - 8:00  How to stop waiting for build/deploy and enjoy coding again
  25 percent of developers say that their JEE projects take over two minutes to deploy, every time they want to see their changes. Since on average we deploy five times an hour, we are watching the logs roll by, or switching to email and losing focus, for more than an hour every day.

In this talk, Jevgeni Kabanov will highlight three key techniques that you can start using immediately to drop the time from hitting Ctrl+S to refresh your browser down to less than one second. We will start by discussing exploded development and some shortcuts you can take to eliminate the build scripts from your everyday life. Then we will review some ways to bypass or speed up redeployment. We will take a look at JEE redeployment, OSGi modules, special framework support that exists in Grails, Seam, Tapestry5 and RIFE, and JVM HotSwap. We will cover what you can do for free, and introduce a class reloading JVM plug-in called "JavaRebel", that solves the problem for peanuts.

After this talk, you will leave with a clear idea of at least three ways to reduce your turnaround, and measurably save your team at least an hour per day.

6:30 - 8:00  Adobe Flex - James Ward
  Java and Flex
Building highly interactive software that users love to use is usually a challenging endeavor. However, the open source Flex SDK and Java are a perfect combination of technologies for building very rich and highly interactive software for the Web and the desktop. The communication between the Java back-end and Flex front-end can utilize a number of different communication protocols, but the easiest and best performing is the open source BlazeDS library. This session covers the fundamentals of using Flex, Java, Spring, and BlazeDS to build rich and highly interactive software for the Web and the desktop.

6:30 - 8:00  Legacy Code Rescue - Andy Lawrence
  Michal Feathers defines Legacy Code as any code without a test.  With that definition we all have a lot of legacy code that we need to learn how to work more effectively with.  This presentation will cover several techniques to Evaluate the Testability of Your Code, Deal with Complex Items to Mock Out, and Perform Manual and Automated Characterization Testing.  Many times we have a “Chicken and Egg” problem with testing and refactoring of Legacy Code.  We will discuss how to determine which comes first.
  About Andy Lawrence
  Part of my role as a tech lead is to mentor folks about (mostly automated) testing strategies and practices. I love learning about better ways of getting software tested to produce value sooner. I work with large corporations mostly, where there typically is no testing culture outside a traditional QA process. I believe I can bring prospective to the discussions on introducing automated testing strategies to corporations. The ability to adopt a strategy is often a very strong indicator of the actual viability of it.

6:30 - 8:00  10 Things for Spring Cleaning - Todd Kaufman
  No single technology or framework has changed the landscape of Java development as the Spring Framework has over the last 4 years. The days of complex, time consuming, and untestable APIs and specifications are now a distant memory. They have since been replaced with Spring enabled applications that are simple enough to develop for the majority of cases, yet flexible and powerful enough to tackle the difficult fringe scenarios.

This talk aims to give the every day Java developer a few more tools to add to their Spring enabled toolbelt. It will cover some obscure features of Spring that you've been largely unaware of like the JAMon performance monitoring, and dynamic language support. Additionally, it will cover some of the powerful facilities provided by Spring that have not been widely adopted like Spring Security for data masking, Caching support with pluggable cache providers, and scheduling support with Quartz.
  About Mr. Kaufman
  Todd Kaufman is a developer, architect, manager, and cheerleader of IT projects large and small. He has 10 years of experience in development with the last 8 focusing on Java in the Enterprise. Todd has been an advocate of the Spring framework for the last 3 years and is continually amazed at the simplicity that it brings to Java development. Todd is currently working as the manager of Java and Dynamic Language studios at Quick Solutions Inc., a leading IT Staffing and Solutions Company in Central Ohio.

6:30 - 8:00  Guice
  Empower your applications with Guice from Google, an Open Source dependency injection framework designed to increase developer productivity, code readability.

From Eric Burke:

At the end of the day, I compared my (Guice) modules — written in Java — to my Spring XML files. The modules are significantly smaller and easier to read.

Then I realized about 3/4 of the code in my modules was unnecessary, so I stripped it out. They were reduced to just a few lines of code each.

6:30 - 8:00  Terracotta by Orion Letizi
 

Within every innocent web application lies a sleeping monster. There comes a time when every successful web application outgrows its single-machine architecture. Whether for high-availability, scalability, or both, the adult web application must grow to live on more than one application server. That’s when the latent beast strikes: the State Monster.

The most recent accepted wisdom about solving application state problems in a scaled-out production architecture is to make your web application “stateless”—i.e., externalize all application state out of the application tier so that any application server can serve any user request. Unfortunately for the owners of such applications, making it “stateless” is hard to do, corrupts the programming and data model of the application, and pushes the problem out to other pieces of infrastructure that are ill-equipped to handle it.

Stateless programming is hard on the application developer, hard on the application infrastructure, and hard on the application. There must be a better way to write business applications. In this talk, we will discuss the current “stateless” application paradigm, its shortcomings, and a new alternative using Terracotta’s open-source availability and scalability technology for the Java Virtual Machine.

6:30 - 8:00  Real World Grails by Scott Davis
 

Scott Davis is the Editor in Chief of aboutGroovy.com. The website, in addition to being, umm, about Groovy, is implemented in Grails. This talk shows you how to get started with Grails, but also talks about the experience of using it in a live, production web site.

Grails is a web framework that maximizes the strengths of familiar Java libraries — Spring, Hibernate, and Sitemesh, to name a few — while minimizing the XML jockeying it usually takes to get them all to play nicely with one another. It brings “Convention over Configuration” to Java. It uses Groovy as the language to glue the pieces
