Sessions at OSCON Java 2011 about Java on Tuesday 26th July

In my technical presentation, I'll be discussing all of the changes to the Java programming language since its inception. In this this keynote, I'll focus my attention on the starting point: I'll present my candidates for the best and worst features in the platform as it was originally released (JDK 1.0), and explain the reasoning behind my choices.

Keynote by Bob Lee, CTO, Square Inc.

Java is a great language but it's not supported on all mobile platforms. This session will show you how to use the open source GWT Java->JavaScript compiler and the PhoneGap build tool to create great mobile applications in Java that run on virtually all smartphone OSes: including webOS, Android, and iOS. We will see how to get started, build a few apps, and adapt them to different screen sizes.

BrowserMob, a Portland-based cloud load testing and monitoring service, spins up thousands of servers every day in various cloud environments, including Amazon, Rackspace, and GoGrid. Learn from the founder about the various open source Java tools he built upon to design a highly scalable, modern cloud-based architecture.

Platform-as-a-Service is the result of taking middleware platforms and cloud enabling them so they truly run in the Cloud. In this session, Paul Fremantle, CTO of WSO2, will look at PaaS and in particular Open Source PaaS. What are the key aspects, where is this going and how to get started. PaaS is a key component of the future of Java in the Cloud - this session is indispensable to learn more.

Securing your applications can be a painful and confusing process, but it doesn't have to be. Apache Shiro simplifies all aspects of application security without sacrificing power or flexibility. Les Hazlewood, Apache Shiro PMC Chair, will explain all of Shiro's core features and demonstrate how to easily secure your own application- from small mobile to large enterprise applications.

Learn about new Java SE 7 features.

Vaadin Framework provides a desktop-like programming model on the server for creating Rich Internet Applications (RIAs) in plain Java - without the need for HTML, XML, plug-ins or JavaScript. In this session, one of the core Vaadin developers lays out the key concepts of the server-side RIA development model and shows how to build an application with Vaadin ground up.

Java EE 6 is a drastic improvement over previous revisions of the platform. But regardless of how significant the releases are, it’s not long before we want more. In this talk, you’ll discover that waiting around for Java EE 7 isn’t your only option, thanks to the portable extension SPI introduced by CDI.

To prove that the Java EE platform is truly extensible, we’ll hack rather than talk theory. We’ll go over the options you have for enhancing the application, from registering custom beans, interceptors and decorators, to customizing dependency injection points, to aliasing annotations, to augmenting the annotation-metadata on registered beans, to introducing custom scopes. The talk will cover when and how you weave these enhancements into the container lifecycle using the CDI eventing system.

Having looked at some standard examples, we’ll unlock some shortcuts and shorthands that are provided by the portable Seam Solder library. Examples we’ll be drawn from the growing ecosystem of Open Source portable extensions. Java EE 6, you’re going to be pwn’d. W00t!

The Java programming language has evolved significantly since its introduction in 1995. In this talk, I'll discuss language changes from the addition of assertions in JDK 1.4 through Project Coin in Java 8, discussing what worked, what didn't, and why. Finally, I'll discuss ongoing efforts (Project Lambda for Java 8) and future plans, in light of the lessons learned from previous changes.

Learn how the Java Community Process is structured and how Java standards are developed.

Twitter is the largest Ruby on Rails installation on the web right now -- however, we have been moving from solely hosting Rails applications to a mixed Rails and JVM deployment. This migration has been ongoing for a few years at Twitter and we now run several back-end, high-throughput, and critical components on the JVM.

In this session you'll learn about Oracle’s strategy for and inner workings of OpenJDK, the community where the development of open source implementations of the Java Plaform, Standard Edition takes place.

The Spring framework is the most ubiquitous Java framework today and the easiest way to solve many problems. At some point, however, developers start to feel Java applications just can't be any simpler because Java itself is not very simple. It is at this juncture that most people look for alternatives. For those, there is Spring Roo, the highly productive development framework for Spring users.
