"The central enemy of reliability is complexity." (Dr. Daniel Geer)

Java is a powerful programming language. A smart developer can do nearly anything with Java. So the next question is, "How quickly can it be done? How many lines of code does it take to do common tasks?" Groovy greases the wheels of Java by decreasing the complexity of the language while preserving the raw power. At first glance, you might think that this talk is simply about how Groovy drastically reduces the lines of code you need to write. What this talk is really about is bringing simplicity, clarity, readability, and yes, beauty to your source code.

In this talk, you'll see common problems presented in Java and the corresponding solutions in Groovy. From something as simple as defining a JavaBean up through File I/O, XML, networking, and database interaction, Groovy offers identical capabilities in a fraction of the lines of code.

By Scott Davis

"XML is like violence: if it doesn't solve your problem, you aren't using enough of it." (Anonymous)

XML is everywhere. Whether you are dealing with local configuration files (web.xml, struts-config.xml) or remote web services (SOAP, REST, RSS, Atom), the modern software developer needs to be able to request, slice, and dice XML with ease. That requires a set of razor-sharp tools that reduce the inherent complexity of the problem, not multiply it. Once you see XML tremble in fear at the awesome power of Groovy, you'll wonder what you ever did without it.

In this talk, we look at various Groovy tools to create, parse, and export XML. To read in XML, we'll explore the XmlSlurper and the XmlParser. To write out XML, we'll use the MarkupBuilder, StreamingMarkupBuilder, and the XmlNodePrinter. We'll go beyond simple Plain Old XML (POX) and demonstrate using namespaces, CDATA blocks, and more.

"Simplicity is the ultimate sophistication." (Leonardo da Vinci)

The history of computer programming has been bridging the gap between what the user says ("We need to add sales tax to each item in the order") and what the programming language requires you to say ("for Iterator i = orderList.iterator();"). Building Domain Specific Languages (DSLs) allow you to express the solution in the language of the domain user instead of the language of the programmer.

DSLs can be written in any programming language, but the more flexible the programming language used, the closer to plain English the DSL can be. Groovy is a dynamic language for the Java platform that is ideally suited for creating DSLs. Come see how Groovy can leverage the power of Java in a way that your users might actually be able to read and understand.

"There's an old story about the person who wished his computer were as easy to use as his telephone. That wish has come true, since I no longer know how to use my telephone." (Bjarne Stroustrup)

The "lizard brain" is the oldest part of the human brain -- the part responsible for autonomic functions like breathing, heart rate, and navigating websites. OK, maybe not that last part, but your website should be easy to use. Stupid easy. Lizard brain easy. Any time your user spends figuring out how to do something -- even for a split second -- is wasted time due to poor design. Inspired by Steve Krug's book "Don't Make Me Think", this talk answers the question, "Why is that website so hard to use?"

In this talk, we look at what make a "good" website "good". Simple changes in the layout or sort order can yield drastic improvements. We'll get inside the heads of typical users and see how their view of our website is drastically different than what we painstakingly planned out. You'll learn how to cater to "Browsers" and "Searchers" -- the human kind, not the software kind. "Lizard Brain Web Design" answers these questions and more in a funny and informative way.

By Scott Davis

"The challenge of modernity is to live without illusions and without becoming disillusioned." (Antonio Gramsci)

There are plenty of sarcastic "Web 2.0" checklists out there -- be perpetually in BETA, when in doubt add rounded corners, etc. While we can all laugh at the superficial aspects of the Web 2.0 revolution, there are plenty of serious aspects to it as well. Is your website mash-up friendly or hostile? Do you tell your visitors when things change (via RSS or Atom syndication), or do you expect them to check in daily for updates? Is your website a silo or a part of a larger ecosystem?

In this talk, we discuss what makes a "modern shiny Web 2.0" website look the way it does. But we go beyond simple look and feel as we catalog the common features in modern websites and show you how to implement them yourself.

By Scott Davis

"The proof of the pudding is in the eating. By a small sample we may judge of the whole piece." (Miguel de Cervantes Saavedra)

Most Grails tutorials demonstrate how easy it is to build simple CRUD (Create/Retrieve/Update/Delete) applications. While skinning a database with a web front-end is undeniably one beneficial aspect of Grails, it isn't the only thing Grails is good for. As you'll see here, Grails can be used to build a wide variety of web applications. You won't see a single HTML table with "edit" and "delete" links, I promise.

In this talk, we look at a variety of Grails applications that go beyond the simple CRUD metaphor -- blogs, wikis, maps, portals, and more.

Most of the software world has realized that BDUF (Big Design Up Front) doesn't work well in software. But lots of developers struggle with this notion when it applies to architecture and design. Surely you can't just start coding, right? You need some level of understanding before you can start work. This session describes the current thinking about emergent design & evolutionary architecture, including both proactive (test-driven development) and reactive (refactoring, composed method) approaches to discovering design. The goal of this talk is to provide nomenclature, strategies, and techniques for allowing design to emerge from projects as they proceed, keeping you code in sync with the problem domain.

Refactoring is a fine academic exercise in the perfect world, but we don't really live there. Even with the best intentions, projects build up technical debt and crufty bad things. This session covers refactoring in the real world, at both the atomic level (how to refactor towards composed method and the single level of abstraction principle) to larger project strategies for multi-day refactoring efforts. This talk provides practical strategies for real projects to effectively refactor your code.

Most developers think that "TDD" stands for Test-driven Development. But it really should stand for "Test-driven Design". Rigorously using TDD makes your code much better in multiple ways.

This session demonstrates how stringent TDD improves the structure of your code. I discuss TDD as a technique for vetting consumer calls, using mock objects to understand complex interactions between collaborators, and some discussions of improved code metrics yielded by TDD. This session shows that TDD is much more than testing: it fundamentally makes your code better at multiple levels.

When you were hired by your current employer, you may think it's because of your winning personality, your dazzling smile, or your encyclopedic knowledge of [insert technology here]. But it's not. You were hired for your ability to sit and concentrate for long periods of time to solve problems, then placed in an environment where it's utterly impossible to do that! Who decides that, despite overwhelming evidence that it's bad for productivity and people hate it, that you must sit in a cubicle? The furniture police! This keynote describes the frustrations of modern knowledge workers in their quest to actually get some work done, and solutions for how to gird yourself against all those distractions. I talk about environments, coding, acceleration, automation, and avoiding repetition as ways to defeat the mid-guided attempts to sap your ability to produce good work. And I give you ways to go on the lam from the furniture police and ammunition to fight back!

This session introduces JSF 2.0 fundamentals, with emphasis on new features in JSF 2.0.

JSF 2.0 has been a long time coming, but now that it's here, it boasts an impressive set of improvements over JSF 1.X, including standardization of Facelets as the default display technology, a much richer event model, and built-in support for Ajax. Come to this session to see how you can use Java's standard web application framework to create industrial-strength web applications. This session will cover the following features of JSF 2.0: Resources Using Groovy System events Bookmarkable views Templating

Prerequisite: Familiarity with JSF, or other component-based frameworks

By David Geary

This session covers two of the most important features of JSF 2.0: composite components and built-in Ajax.

JSF is a component-base framework. Components are a powerful reuse mechanism, but they were rendered nearly inconsequential in JSF 1.X, because components were so difficult to implement. JSF 2.0 makes implementing cusomt components easy with a new feature that builds on Facelets and the new resource capabilities in JSF 2.0: composite components. This session shows you how to implement your own components with JSF 2. Additionally, this session covers the built-in Ajax that comes with JSF 2.0. Come to this session to see how you can easily implement custom components with integrated Ajax capabilities.

Prerequisite: Familiarity with JSF, or other component-based frameworks. Familiarity with Ajax. This session builds on the JSF 2.0 Introduction talk, so it is helpful, although not required, if you attend the intro talk before coming to this session.

Learn to implement web applications with GWT.

Google Web Toolkit lets you create killer Java-based web applications using familiar Swing and AWT idioms. This session will introduce you to GWT and teach you the fundamentals of using this cutting-edge framework for creating rich user interfaces that run in a browser. For most of this session, and the session that follows--GWT fu, Part 2--I will live code a desktop-like, ajax-based, web application that illustrates the awesome power of GWT. In this session, I will cover the following topics: Widgets Remote procedure calls and database access Event handling Ajax testing

Prerequisite: Familiarity with a component-based framework, preferably a desktop application framework

Learn to do amazing stuff with GWT.

This session picks up where GWT fu, Part 1 left off. In this session, I will continue live-coding the Places application. In taking the Places application to its exciting conclusion, I will cover the following advanced aspects of GWT: Dialog boxes Sinking events DOM elements Working with HTML Modules Image loading and busy cursors Event previews Timers In this session, I focus primarily on implementing a viewport widget in a custom module, and using that widget in the Places application. When I'm done, we'll have a very cool web application that shows the awesome potential of Google Web Toolkit

Prerequisite: GWT fu, Part 1 is not a prerequisite for this session, but it will help if you have some familiarity with GWT.

Many development shops have made the leap from RCS, Perforce, ClearCase, PVCS, CVS, BitKeeper or SourceSafe to the modern Subversion (SVN) version control system. But why not take the next massive stride in productivity and get on board with Git, a distributed version control system (DVCS). Jump ahead of the masses staying on Subversion, and increase your team's productivity, debugging effectiveness, flexibility in cutting releases, and repository redundancy at $0 cost. Understand how distributed version control systems are game-changers and pick up the lingo that will become standard in the next few years.

In this talk, we discuss the team changes that liberate you from the central server, but still conform to the corporate expectation that there's a central master repository. You'll get a cheat sheet for Git, and a trail-map from someone who's actually experienced the Subversion to Git transition. Lastly, we'll even expose how you can leverage 75% of Git's features against a Subversion repository without ever telling your bosses you are using it. Be forewarned that they may start to wonder why you are so much more effective in your checkins than other members of your team.

Prerequisite: Basic understanding of Subversion or similar version control system

Maven has been on the Java build tools scene for quite a number of years, but the adoption rate in enterprises is now going through the roof. Maven can seem daunting, but this presentation will equip existing Maven users with more efficient techniques and tools to overcome the biggest perceived Maven hurdles and build issues with ease.

We'll examine tools to help you find artifacts in central repositories, manage your corporation's internal Maven artifacts with a proxy tool such as Nexus, view and override dependency graphs, dependency management and multi-module best practices, create OS specific profiles, and leverage the latest Maven plugins for the top Java IDEs.

Topping it off, we will review migration paths from Ant, and why Maven just makes sense with your company's use of the ever growing web of open source libraries. This presentation will take beginning and mid-level Maven users up to a higher level of efficiency and mastery.

Prerequisite: Basic Maven knowledge

By Matthew McCullough

Open Source is not just a suite of libraries you consume within your application, but now reaches into the space of tools to help you troubleshoot and improve your applications.

This session will quickly survey a wide range of tools across the Java, Networking, Filesystem, SOAP, REST, HTML, CSS and JavaScript realms. We'll look at applications such as VisualVM, which help you analyze your heap and garbage collection cycles of both local and remote applications. Performance and load testing tools such as JMeter will expose bottlenecks, threading, and scalability concerns of everything from Java modules to Web Apps (even ones that don't use any Java).

Learn how web service tools such as SOAPui and TCPMon allow you to inspect your SOAP and REST calls at the data structure level, and how Firefox Poster lets you test web services right from the browser. And when only a raw look will do, we can always fall back on the venerable TCPDump. This tool-centric presentation will expose developers to approaches to inspect, debug, tune and troubleshoot Java desktop apps, language-neutral web apps, and framework-neutral web services using Open Source Tools.

By Matthew McCullough

iPhone development is all the rage both in the mobile entertainment, social networking, and productivity application spaces. As a Java developer, prepare yourself to be a participant in aspects of this new breed and platform of development. Hop on board with a quick start to iPhone application coding in Objective-C and integration with some of our favorite Java web service back-ends such as RESTful Grails.

We'll build out a graphical demo application on the iPhone that depends on and responds to data from a Java web service; then we'll deploy it live to the desktop simulator, and finally, a real iPhone. This presentation will make you conversant in iPhone development procedures and able to make smart decisions about your back end Java web services ability to serve data to iPhone native client apps.

By Ted Neward

  Even though the Java 7 JSR has yet to be formed, some interesting things are beginning to emerge from Sun about what Java7 may include when its formal release contents are finally made public.

In this presentation, we'll examine some of the forthcoming details, including some of the JSR-166 "add-ons" like the Fork/Join framework, some of the proposals for extensions to the JVM to support dynamic languages, and the so-called "closures" proposals circulating around.

By Ted Neward

For so many Java developers, the java.util.* package consists of List, ArrayList, and maybe Map and HashMap. But the Collections classes are so much more powerful than many of us are led to believe, and all it requires is a small amount of digging and some simple exploration to begin to "get" the real power of the Collection classes.

In this presentation, Java developers will see the basic breakdown of the Collection API designs, the relationship of the interfaces to the implementations, how to create a new Collection implementation, and how the new Collections introduced as part of JSR-166 (the concurrency JSR) and Java6 make their programming lives easier.

By Ted Neward

With the release of the OpenJDK source code, Java developers have been given a unique opportunity to peer inside the hood of the JVM, see what's there, and how Java code actually executes.

In this presentation, we'll talk about how to get the OpenJDK codebase, how to compile it (for both Windows and Linux systems), and point out some of the more interesting aspects of the JDK source base. Developers will walk away with a deeper appreciation for exactly what happens when they run Java code. Innocents beware--we're a long way from "Hello, Java" with this one.

By Ted Neward

Permissions, policy, SecurityExceptions, oh my! The Java platform is a rich and powerful platform, complete with a rich and powerful security mechanism, but sometimes understanding it and how it works can be daunting and intimidating, and leave developers with the basic impression that it's mysterious and dark and incomprehensible. Nothing could be further from the truth, and in this presentation, we'll take a pragmatic, code-first look at the Java security platform, including Permissions, the SecurityManager and its successor, AccessController, the Policy class and policy file syntax, JAAS, and more.

For an intermediate-level audience.

By Ted Neward

So you know the platform security model, and now you want to use it in new and interesting ways, like creating a custom Policy implementation, a custom Permission, or create a custom security context in which code will execute. Perhaps you even wish to make certain objects accessible only to those with the right permissions, or cryptographic key. Nothing could be easier, despite Java security's reputation as a dark and arcane place.

In this presentation, we'll pick up where the "Platform Security" talk leaves off, and demonstrate how to engage the security model of the JVM at a much deeper level, regardless of your favorite programming language: Java, JRuby, Groovy, Scala, ....

Java's threading capabilities took a serious turn for the better with the release of Java5, thanks to the incorporation of the java.util.concurrent packages, a set of pre-built components for thread pooling and execution, synchronization, and more.

In this presentation, we'll explore the Thread API, the Java threading model beneath it, and the enhancements made in Java5 to make it easier for Java code to walk and chew gum at the same time.

By Ted Neward

Java's threading capabilities have been a part of the Java platform since its inception, yet for many Java developers, using Threads still remain a dark and mysterious art, and synchronization beyond the use of the "synchronized" keyword is almost unknown.

In this talk, we'll explore the Java "monitor" concept, and how a monitor isn't quite the same thing as a lock from other concurrency systems. We'll see how monitors can be used to perform signalling across threads, and then how the new java.util.concurrent API (introduced in Java 5) can be used to simplify the same sorts of tasks that used to require deep knowledge of the synchronized keyword. Finally, we'll answer that age-old question, "Why did the multithreaded chicken cross the road?"

Prerequisite: The Busy Java Developer's Guide to Concurrency (Part 1: Threads)

By Ted Neward

Ever since its 1.1 release, the Java Virtual Machine steadily becomes a more and more "hackable" (configurable, pluggable, customizable, choose your own adjective here) platform for Java developers, yet few, if any, Java developers take advantage of it. Time to take the kid gloves off, crack open the platform, and see what's there. Time to play.

In this presentation, we'll examine several of the "hackable" customization points inside the JVM: the boot classpath, allowing us to add or modify existing JDK classes without violating the license agreement; the JNI Invocation API, allowing us to create custom Java launchers to establish an environment for the JVM that corresponds to exactly the way we want it; or even replace core Java classes with our own versions. Innocents beware--we're a long way from "Hello, Java". (Attendees should have some familiarity with C/C++ code and native build practices to get the most out of this talk.)

By Ted Neward

Scala is a new programming language incorporating the most important concepts of object-oriented and functional languages and running on top of the Java Virtual Machine as standard "dot-class" files. Sporting the usual object-oriented concepts as classes and inheritance, Scala also offers a number of powerful functional features, such as algebraic data types, immutable objects by default, pattern matching, closures, anonymous functions and currying, and more. Combined with some deep support for XML generation and consumption, Scala offers Java programmers an opportunity to write powerful programs with concise syntax for a new decade of Java programming.

In this presentation, we take the Scala language, its support for XML, it's immutable and functional approaches, and build a simple XML service with it, no JAX-WS needed (or wanted). Deploying the service as a simple servlet, we show it being consumed from a traditional JAX-WS service client, and from a more "hip" REST approach.

By Michael Nygard

Is your system small, medium, large, or super-size? Is traffic on it's way up?

Architecture patterns and structures that work at one scale seldom work across all of them. A communication style that's appropriate for small websites will probably fail badly if you apply it to world-wide networks of computers. Likewise, structures that work for large-scale systems are probably too complex and expensive to be worth it for small sites.

In this talk, Michael will discuss the notion of "design envelopes" for architectures. He will explore several common scaling strategies and map them to different system scales. During this session, Michael will present reference architectures for systems at a variety of scales. It's sometimes possible to scale smoothly from range to range, but it can be extremely disruptive if you don't plan for it. Along the way, he'll also address the different dimensions of scalability problems: traffic, content, data volume, and operations.

By Michael Nygard

Cloud computing is taking the world by storm. Amazon's Web Services, EC2, and S3 provide completely virtual infrastructure, letting startup and existing companies create sites and web applications faster than ever before.

In this session, Michael will use cloud computing to create and deploy a fully-functional web site. You will learn how to create and run your own virtual infrastructure in the clouds.

It used to take weeks and months to stand up a new site. You had to buy hardware, rent (or build) space, rack, stack, and cable it, and then you'd finally get to start installing operating systems, databases, and so on. These days, none of that is necessary. You can run a real business on the net without ever owning anything. Best of all, you can be up and running in a single day. A day? Trivial you say? OK, we'll make it an hour and a half, with time for questions.

By Michael Nygard

Servers, storage, networking, backups... they're all vanishing into the "clouds". Cloud Computing is the emerging architecture for massive, scalable infrastructure that your company doesn't have to own or operate.

In this session, Michael will discuss the ingredients of real cloud computing and how you can apply it to your applications. He will show several architectures and discuss applications that fit each of these models. Finally, he will also talk about some of the pitfalls and problems that cloud computing customers can encounter.

The term "Cloud Computing" can be applied to everything from Software-as-a-Service (formerly known as Application Service Provider) to virtual infrastructure, grid computing, and even remote backup services. Some of these make sense, but some are just bandwagon-jumping and buzzword bingo. From the "zero servers" web startup to the corporate IT department battling server-sprawl, cloud computing has many manifestations. This session will differentiate among the various types of cloud computing and describe applicable use cases.

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.

Software development is expensive, when business rules are hard-coded in your application's source code, changes and additions to those rules translate to wasted time and money. Good object-oriented, component-based approaches can alleviate the burden of keeping up with changes in the business world but they still require that expert knowledge of the changes be passed from the decision makers to the business analysts and finally to programmers that need to implement these changes. Business Rule Engines and Business Rule Languages are based on the basic premise of separation of concerns by empowering business domain experts to express the rules of business in a way that it is directly usable

By Brian Sam-Bodden

In this session you'll learn some of the more advanced features of Drools; a pure-Java Rule Engine. This session will walk through the construction of an advanced Rules application covering such topics as:

• Fine control and monitoring of a Working Memory session
• Using Decision Tables
• Advanced Rule Language Features
• Building Domain Specific Languages
• Managing your Rules

Many of the problems that we deal with in enterprises around the world are not usually related to the particular infrastructure, framework or programming language chosen but rather to the evolution and maintenance of the business logic that governs those systems. All knowledge in an enterprise is handed down stream until it arrives at the programmer's door. With Rule based systems we can empower those with the business but there is still a fair amount of work to get the ideal architecture for a particular problem in place. In this session you'll learn some of the more advanced features of Drools; a pure-Java Rule Engine. This session will walk through the construction of an advanced Rules ap

This session is designed to be a jam session on all aspects of software architecture and many of the roles of software architect. The The following subject areas will be covered: - Software Development Process - Project Key Mechanisms: Languages and Frameworks - Security: Threats, Securing Code Review, Adding Security to you process - Layers, Partitions and Topologies - VM Optimizations - Usability and User Experience - Optimizing the Web - Ready for Production: Monitoring - Integration - Data Modeling

By Ken Sipe

The agile focus of software development puts heavy focus on user requirements through user stories. However we can not lose sight of the non-functional requirements as well. The software could be written to the exact specification and desire of the user, however if it takes 5 minutes for a request response, or it only supports 2 users or it isn't secure, then we still haven't done our jobs as developers.

This session will focus on the non-functional requirements of software development, namely: Performance, Scalability, Security, and Software Monitoring and Management. Each subject area discussion will include, goals, design practices, tools, and where it fits in the software development life-cycle.

By Ken Sipe

Thoughts lead to words, words lead to action, actions lead to habits. In this session we'll sharpen the development saw in the process of understanding what makes a hyper-productive programmer. The focus will consist of developer habits and development processes.

As described in the book "7 Habits for Highly Effective People", there are habits which are characteristic of highly effective people. Clearly there are hyper-productive developers which distinguish themselves from the development pack? what is it that makes the difference? What are the habits and practices of highly effective developers? This session will focus on individual developer habits, as well as team practices and the processes which result in high quality running software.

By Ken Sipe

The success of an Agile / SCRUM project is a successful start. The first interaction is often referred to as iteration 0. Other iterations have a set of stories with clear acceptance, certain which establishes the velocity of the team and its effort. What then is accomplished in iteration 0? How do we get an Agile process started?

This session will outline all the "pre" activity tasks that lead into an agile development process. As well as the establishment of a task list of iteration 0, include the establishment of development environment, configuration management details. This will include several case histories examples of Iteration 0.

By Ken Sipe

You are using Java, whew!!! No need to worry about memory, the garbage collector will handle that. Those who have had a memory issue in Java are not so naive any more. Often memory utilization and heap sizes are an after thought and are not recognized until the application is in production, often caused by application uptime, production request volume or production sets of data. When the OutOfMemory Error occurs, often the science of development seems to brake down and knobs are turned. First the (-mx) maximum heap space gets adjusted... More is better right. The next OutOfMemory, heads start scratching, code reviews start in earnest, and Google gets several new hits. Did you know that it is possible to get an OutOfMemory error without running out of heap space?

This talk will walk through the underlying details of memory management in the JVM with a focus on VM flags available to help configure the VM. However we can't configure the VM without a detailed understanding of what is going on inside the VM. We'll focus on tools available for analyzing the memory in a running VM. Two actual client case examples will be presented. We'll discuss the differences between the two cases and why the end configurations were quite different.

By Ken Sipe

So your server is having issues? memory? Connections? Limited response? Is the first solution to bounce the server? Perhaps change some VM flags or add some logging? In todays Java 6 world, with its superior runtime monitoring and management capabilities the reasons to the bounce the server have been greatly reduced.
