Brian Goetz - Author of Java Concurrency in Practice

Effective Concurrent Java

The Java programming language has turned a generation of applications programmers into concurrent programmers through its direct support of multithreading. However, the Java concurrency primitives are just that: primitive. From them you can build many concurrency utilities, but doing so takes great care as concurrent programming poses many traps for the unwary.

Java Performance Myths

Performance myths about the Java platform abound, from the general "Java is slow", to the more specific "reflection is slow", "allocation is slow", "synchronization is slow", "garbage collection is slow", etc. Many of these myths have their root in fact (in JDK 1.0, everything was slow); today, not only are many of these statements not true, but Java performance has surpassed that of C in many areas, such as memory management.

Squashing bugs with FindBugs

Does your program have bugs, despite unit tests, integration tests, and code reviews? You bet. Are you using static analysis as part of your QA process? If not, you're probably missing out on some bugs that can be caught before they bite your customers.

Structuring concurrent applications in JDK 5.0

JDK 5.0 is a huge step forward in developing concurrent Java classes and applications, providing a rich set of high-level concurrency building blocks.

The Java Memory Model

What's the worst thing that can happen when you fail to synchronize in a concurrent Java program? Its probably worse than you think -- modern shared-memory processors can do some pretty weird things when left to their own devices.

Brian Sam-Bodden - Java author, Ruby geek and Open Source Advocate

Advanced Object-Relational Mapping with Hibernate

Hibernate is rapidly becoming the tool of choice when it comes to Object-Relational Mapping in Java. For simple applications with fairly simple object models and database schemas, using Hibernate is fairly straight forward. Unfortunately for most of us real applications have complex object-models that need to be wired to sometimes ancient and convoluted database schemas.

Beginning Drools - Rule Engines in Java

Drools is an open source pure-Java implementation of a forward chaining rules engine. Drools can be used in a J2SE or J2EE application and allows you to express rules programatically or by building domain specific rule languages. Learn how Business Rules with Drools can make your Java applications more flexible and robust.

Beginning Object-Relational Mapping with Hibernate

Hibernate is an open source Object-Relational Mapping Framework that mostly automates the tedious and time-consuming task of persisting Java objects to a relational database.
Hibernate is quickly becoming the preferred way for enterprise developers to overcome the object-relational impedance mismatch and a good alternative to the coarse-grained Entity EJBs, low-level raw JDBC, and by-committee specifications like JDO. Learn what your choices in the ORM arena, what to look for in an ORM tool, and how to get started with Hibernate for your next J2SE or J2EE project.

Complex Builds with Ant

Ant has revolutionized the way we build applications in Java and it has become a de facto standard in the Java world. As applications grow in complexity some developers are finding themselves dealing with ever growing and complex builds. Complex builds have to deal with Multiple Operating System, multiple Application Servers, multiple APIs and multiple stages of development.

Brian Sletten - Forward Leaning Software Consultant

Abusing Maven For Fun and Profit : (Near) Zero-Admin Deployments

Ok, I can't promise you profit, but hopefully you'll have fun. Maven 2 introduces a number of new features (including that performance feature) that make it a swell project management tool for development.

Come hear about how we can abuse Maven to manage distributed deployment scenarios before the Modules JSR is done.

Applied AOP

Most people new to Aspect-Oriented Programming (AOP) are fed up with separation of concerns zealots explaining how great their techniques are at dealing with... logging. Ok, you get it. Logging is a cross-cutting concern that can be appropriately modularized. What else does AOP have to offer? A lot, it turns out. This talk will give an introduction to the motivations of AOP as well as a series of concrete examples drawn from enterprise and client side Java. Come learn how AspectJ-flavored AOP can begin to benefit you immediately either in development or production environments. Learn how to enforce architectural policies, find Swing threading issues, reduce the invasiveness of the Observer design pattern or even improve the reusability of your domain models. Now that Spring 2.0 provides support for AspectJ, the time has never been better to learn about these new (but backwards compatible) ways of thinking about building software.

Applied Object-Oriented Metrics

Object-oriented code metrics are a little like Artificial Intelligence: those who did it twenty years ago roll their eyes at the thought and prophesy the same ultimate failure at applicability now. Those who grew up with Java are approaching the topic with new eyes and are finding useful ways of incorporating metrics into their projects. Come hear about tools and ways to measure properties of software, how they might be beneficial and where you are likely to go astray with this approach.

Data Integration : Beyond Cutesy Mashups

Ever since we started doing relational joins, we've looked for ways to tie data together. The web has given us no end of new data sources to integrate but it seems like the best we can come up with is locating Starbucks on Google Maps. The problem with browser-based mashups is that they don't survive the session, we have no way of referring to the results in future queries and ultimately we don't maintain ownership or control of the process.

We want control of our data and our mashup results. We want ever more ways to view, explore and requery them in multi-faceted ways. Do you know what your data integration strategy is for the next few years? Are you sure? You owe it to yourself to come find out.

Git 'R Done : Scheduling Work With Quartz

Software engineers are usually familiar with the notion of scheduled tasks and cron jobs at the OS level. Quartz is a relatively new open source Java API for scheduling jobs in your applications or Enterprise.

Give it a REST

As developers, we sometimes get to make choices about the technologies we use, sometimes not. We base these decisions on personal experiences, recommendations from others and a general sense of where the industry is going.

Web Services have been all the rage for several years now. We have been told time and again that we should be building systems around them; as an industry, we've never been more confused. Perhaps it is time to Give it a REST.

Introducing the Semantic Web

Just as the world is feeling comfortable with the Web, Tim Berners-Lee et al inform us that what we have seen so far is just the beginning. His original plans at CERN were larger and grander. The Semantic Web is the new vision of machine-processable documents and metadata to improve search, knowledge discovery and data integration and management. While there are many naysayers chiding such grand visions, there are also pragmatic and useful technologies emerging that can be applied today.

Resource-Oriented Computing w/ NetKernel : Software for the 21st Century

Imagine the simplicity of REST married to the power of Unix pipes with the benefits of a loosely-coupled, logically-layered architecture. If that is hard to imagine, it may because the architectures available to you today are convoluted accretions of mismatched technologies, languages, abstractions and data models.

NetKernel is a disruptive technology that changes the game. It has been quietly gaining mind share in the past several years; people who are exposed to it don't want to go back to the tired and blue conventions of J2EE and .NET. Not only does it make building the kinds of systems you are building today easier, it does it more efficiently, with less code and a far more scalable runway to allow you to take advantage of the emerging multi-core, multi-CPU hardware that is coming our way.

Come see how this open source / commercial product can change the way you think about building software.

David Bock - Principal Consultant, CodeSherpas Inc.

Capistrano: Application Deployment and More

Capistrano (formerly Switchtower) is a tool originally written to help automate application deployment for Ruby on Rails. It does this well, but it has grown up into a tool capable of much, much more. It can be used for deploying Java applications, updating server configurations acrtoss an enterprise, administering netwoeks, backing up files, and all sorts of other activities. Any activity you might do from the command line, you can now do simultaneously across large numbers of machines, with all machines succeeding (or rolling back in case of failure) together.

Internationalization and Localization in Java

Internationalization and Localization in Java is easy, right? Everyone knows you just store your strings in some resource bundles, set the locale, wave your hands a little bit, and your application is good-to-go. Right? Maybe not... Java provides some great utilities to get started, but leaves you needing more when it comes to things like screen layout, cultural sensitivities, semantic differences in translation, use of color and iconography, and other issues.

Introducing Agility to Large Organizations

For several years, I was a member of a team of people caught in the middle of a 200+ person software development company, with senior management wanting "buzzword compliant process improvement" such as CMMI, and engineers wanting more ?agile? solutions (and people on both sides confusing Agile with ad-hoc). We were responsible for sorting it all out. Reconciling this was a herculean effort, and can be a source of lessons learned for your own process improvement efforts. Are you trying to be more agile in your organization? Are you expecting it to be harder than it needs to be because of political and bureaucratic forces beyond your control? Do you have to "educate" your senior management to protect them from buzzwords? Come learn from my successes... and mistakes.

Maintaining Project Integrity with JDepend, Macker, PMD, Maven, and other open source tools

How many times have you started a new project only to find that several months into it, you have a big ball of code you have to plod through to try to get anything done? How many times have you been the ?new guy? on an established project where it seems like the code grew more like weeds and brambles than a well-tended garden? With a few good structural guidelines and several tools to help analyze the code, we can keep our project from turning into that big ball of mud, and we can salvage a project that is already headed down that path.

David Geary - Author of Graphic Java and co-author of Core JSF

Ajaxian Faces

JavaServer Faces is a perfect platform for implementing Web 2.0 interfaces with Ajax. This session explores how you can use these two potent technologies--JSF and Ajax--together to create applications that look and behave like desktop applications but run in the browser.

JavaServer Faces: A Whirlwind Tour

In April 2005, annual growth rates for jobs in JavaServer Faces, Struts, and Ruby on Rails were all at about 0%. Today, Struts' growth rate still hovers around 0%, but JSF and Rails have taken off. At the end of 2007, both JSF and Rails were growing at a rate of between 400-500% annually (according to indeed.com).

JSF has passed the adoption tipping point, and is now the Java-based framework of choice, as is evidenced by its ecosystem. From vendors such as MyEclipse and RedHat to open source projects such as Seam, Facelets, and Ajax4JSF, JSF is where the action is.

Come see why JSF is so popular. In this code- and demo-intensive session, I'll show you the fundamentals of JSF.

Prerequisite: Some knowledge of Java-based web applications, such as Struts, is a plus, but is not required. If you have a significant experience with JSF, you probably already know most of what's covered in this session.

Killer JavaScript Frameworks: Prototype, Scriptaculous, and Rico

An introduction to the popular Prototype JavaScript framework, and two frameworks built on top of Prototype: Scriptaculous and Rico.

RAD JSF with Seam, Facelets, and Ajax4jsf, Part One

In this session, see how you can get Ruby On Rails-like productivity on the Java side of the house with this compelling combination of technologies.

RAD JSF with Seam, Facelets, and Ajax4jsf, Part Two

A continuation of a 2-session presentation on Seam, Facelets, and Ajax4jsf.

The Google Web Toolkit, Part One

Developing highly interactive web applications, for the most part requires knowledge of a wide array of technologies: HTML, CSS, JavaScript, XMLHttpRequest, JSP, JSF, etc.

With the Google Web Toolkit (GWT), Google turns that notion of development on its head. Instead, you implement Ajax applications by writing almost entirely in Java. You use an AWT-like API, which the Google compiler compiles to JavaScript that runs on the client.

The Google Web Toolkit, Part Two

The second part of a 2-session presentation on the Google Web Toolkit.

Jeff Genender - Co-author of Professional Apache Geronimo

Building a Service Oriented Architecture with ServiceMix

There is a big buzz and a lot of hype about Service Oriented Architecture (SOA) and the Enterprise Service Bus (ESB). A solid SOA architecture allows you to use standards-based, pluggable, and loosely coupled services to integrate and communicate the critical business logic from disparate systems. This essentially allows a common ground for different systems to interact with each other. But there is more to a good SOA implementation than simply integrating services. This is where orchestration and other key concepts become important, and an ESB helps fill in this gap.

High Availability Java

Clustering and high availability is a critical topic in Java Enterprise circles. There are many strategies to clustering but not every strategy is right for every application. Knowing which strategy for which application is critical in weighing scalability vs performance. This session discusses clustering topologies such as full replication, distributed clustering, master/slave, and other strategies.

Migrating from Tomcat To Geronimo

Have you thought about moving your web applications to an application server, but were afraid to try? Geronimo may be the application server for you! Since Geronimo allows you to take on an application server a little at a time by building the stack that is right for you, migrating your Tomcat applications to Geronimo is a great first step.

Mark Fisher - Spring Integration Lead

Enterprise Security with Spring

Spring Security (formerly known as 'Acegi') enables self-contained, consistent, and extensible solutions for securing your applications. Version 2.0 provides major enhancements including a domain-specific XML namespace, convention-based defaulting, and annotation support. This provides a significantly simpler experience for developers while still supporting the same degree of flexibility.

Message Driven POJOs with Spring

Spring 2.0 introduced support for Message-Driven POJOs meaning that it is now possible to receive JMS messages asynchronously and delegate the handling of those messages to simple objects even within a lightweight application running outside of any application server. If your POJO has a return value, it will automatically be sent to a response destination.

Spring 2.0: New and Noteworthy

Spring 2.0 has marked a major advance in the Spring Framework. While still maintaining backwards compatibility, this release adds quite a few new features. What are those features and how do they add value? Come by and see.

In this session we'll provide a practical tour of what's new in Spring 2.0. Spring 1.x users who are looking to upgrade to Spring 2.0 will love this session. If you're not using Spring already, this talk will give a great overview of the things you're missing out by not using Spring 2.0.

The Role of Spring in an ESB

An Enterprise Service Bus (ESB) brings flow-related functionality such as message routing and transformation to a Service-Oriented Architecture. An ESB also provides a layer of abstraction with endpoints for various protocols and transports. These features promote decoupling of integration logic from business functions, flexibility in the transport layer, and pluggability of POJO services.

Scott Davis - Author of "Groovy Recipes" & TDD Expert

Ajax development with the Yahoo! UI Library and Grails

Yahoo! is a company that eats its own dog food. They open sourced the Ajax code that drives many of their own websites, including their eponymous homepage, Yahoo! Mail, and Yahoo! News. Come see first hand how the various pieces of the library work together as a seamless whole.

Atom: From Blogging to Data Syndication

You've probably read a blog or two, but have you ever looked at the underlying protocol that makes the blogosphere work? RSS kick-started the phenomenon, but Atom is the IETF specification that codifies it. Atom as a blogging dialect is interesting, but Atom as a data syndication format is something that is on the rise. Google recently deprecated its SOAP API and is aggressively moving towards Atom as its preferred way to interact with its services.

Groovy and Java: The Integration Story

I'm attracted to Groovy because of its spirit of inclusiveness. Because it extends my platform of choice, not replaces it -- include a single JAR in your classpath and you are Groovy-enabled. Because it offers full bidirectional integration with Java. Because it offers a nearly flat learning curve for experienced Java developers. Come see how you can use Groovy to augment your existing Java codebase.

Groovy and Java: The Integration Story

Groovy: The Next Generation of Java

This is the year of the dynamic scripting language. Ruby (and Rails) has won the hearts and minds of many independent software developers. JavaScript is experiencing a renaissance thanks to the wild success of AJAX and websites like Google Maps. And Groovy (JSR-241) brings the same level of excitement and "scripting goodness" to the Java platform.

Groovy: The Next Generation of Java

Mocking Web Services

In this talk, we'll survey the web services exposed by leading websites (Google, Yahoo, Amazon, eBay) and discuss how they can be easily mocked up for testing purposes and to aid offline development. You'll see working examples of RESTful, SOAP, and JSON web services, as well as strategies for unit and functional testing your asynchronous, service-oriented architecture.

Real World Grails

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.

The Zen of REST

Google quietly deprecated their SOAP search API at the end of 2006. While this doesn't mean that you should abandon SOAP, it does reflect a growing trend towards simpler dialects of web services. Google joins a number of popular websites (Yahoo, Flickr, YouTube, del.icio.us) that offer all of the benefits of web services without all of the complexity of SOAP.
