Easing into Agile

How do you get started with an Agile development methodology? Everyone has been talking about eXtreme Programming for years, but how do you get it introduced to your team? Many times, you're not simply transitioning from from one methodology to another -- you're introducing a methodology for the first time. Adding structure to a previously unstructured endeavor. Adding a touch of discipline where programmers once roamed free.

Holistic Testing

Mark Twain once said, "Everyone talks about the weather, but nobody does anything about it." Do you feel the same way about Unit Testing? Are you actively testing your code, or are you just thinking about testing your code... some day... once you get some more free time...

Real World Web Services

In this talk, we'll survey the web services exposed by leading websites (Google, Yahoo, Amazon, eBay) and discuss how they are driving the AJAX revolution. You'll see examples of RESTful, SOAP, and JSON web services, as well as the strengths and weaknesses of each.

Ajax, Flash, and Java - Choosing The Right Rich Client Technology for Your Next Project

Today's users are beginning to demand richer and richer application experiences. Plain html pages simply don't cut it anymore. Applications like Google Maps (Ajax) and Yahoo Maps (Flash) show how the UI experience can be pushed to the next level. As an IT manager, how do you decide which route to take however? Should you use Ajax because it is the new "it" technology. Is Flash a viable option with its 95%+ browser availability? Perhaps Java deployed through web start is really the best choice in contrast to what the buzz would lead you to believe. This presentation takes a look at these three core rich client technologies from both deployment/user experience and ease of development perspectives.

Creating Polished Swing Applications

Too often, Swing applications are slow, ugly, and hard-to-maintain. It turns out that it doesn't have to be this way. Swing can be used to create highly-responsive, beautiful applications that are very maintainable. If this isn't consistent with your own experience, don't feel bad; its not very obvious how to make Swing sing.

Introducing the Eclipse Rich Client Platform

Rich client application development using Java can be intimidating giving the vast flexibility in application design and structure. It also can be frustrating to create the large number of support services (persistence, menus, event and job frameworks) that a large scale rich client applications needs. The Eclipse Rich Client Platform is one project attempting to solve these issues by providing a core infrastructure that not only provides the day to day services a rich client application developer needs, but also providing a suggested path to guide you down the road of designing your application. This presentation introduces both the Eclipse RCP and the tools provided by the Eclipse IDE that assist developers in writing RCP apps.

Java GUI Deployment 101

This session will introduce attendees to the various options and problems that exist with deployment of a Java UI application written in Swing or SWT. Topics covered will include obfuscation of classes in preparation of deployment, open source installers, and Java Webstart.

JSF: State of the Art

In 2005, JSF hit its stride, as evidenced from overwhelming support from both vendors and the open-source community. JSF 1.0 had plenty of holes, but open-source projects have arisen to address those needs. This session takes a look at three of those projects: Tomahawk (MyFaces component library) FaceletsSeam

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 Web UIs

User interfaces are usually the most turbulent aspect of an application during development. Constant tinkering with the UI means constant changes to your code, so as a UI developer, you want to minimize the scope and effects of those code changes.

Open-source Java provides two powerful software packages that help you manage UI complexity: Tiles and Sitemesh. Tiles composes webpages from discrete regions of your user interface known as tiles. A tile contains a JSP page for layout and one or more JSP pages for content. Sitemesh decorates webpages with decorators that can be associated with URL patterns. Once you set up your decorators, you can decorate pages that match a decorator's URL pattern.

Shale: Turbo-charge your JSF Apps

JavaServer Faces is a well designed user interface framework, but it lacks a number of features you might otherwise expect out of the box; for example, JSF does not explicitly provide support for client-side validation.

So, from the folks that brought you Struts, comes Shale, a collection of useful enhancements to JSF. A top-level Apache Software Foundation project, Shale adds some really cool features to vanilla JSF, including:

Web flow: script dialog flow Remote Method Calls: easily call JavaBean methods from JavaScript Tapestry-like views: code views in pure HTML Use Apache Commons Validator validators on the client or server, or both JSF testing framework: mocks for easy JSF testing

There's a lot of cool stuff in Shale that makes JSF a much more compelling proposition. Come see what it's all about.

Taking Quality to the Next Level through Code Coverage Analytics

Understanding what code coverage represents, how to effectively apply it, and how to avoid its pitfalls will give you an unprecedented understanding of how unit tests may or may not be covering you from sneaky defects.

Unit Testing Best Practices

In the years since JUnit’s introduction, a number of frameworks have been built to enhance its utility for testing and validating XML, controlling the state of a database, testing legacy code, performance testing, and functional web testing.

Unit Testing Java Objects with Groovy

What makes Groovy particularly appealing with respect to other scripting platforms is its seamless integration with the Java platform. Because it's based on the Java language (unlike other alternate languages for the JRE, which tend to be based on earlier predecessors), Groovy presents an incredibly short learning curve for the Java developer. And once that learning curve has straightened out, Groovy can offer an unparalleled rapid development platform.

Advanced Hibernate

Hibernate is easy to get started with, but can sometimes be hard to make efficient or secure. In fact, the default settings for Hibernate createapplications that will run slowly, cause unwanted round trips to the database, and may be more restrictive and/or permissive from a security standpointthan you would otherwise want.

Ajax Architecture

Ajax applications have unique architectural challenges and opportunities. This presentation will show you how to take advantage of the Ajax's strengths, and work around its quirks.

Cryptography for Programmers

For centuries people have used crypto to build (and break) secure systems. Computers have only raised the pitch of conflict, providing enormous cryptographic power at commodity prices. Most programmers do not write their own crypto libraries, instead relying on the services of an operating system or virtual machine. But even with all this support, building secure systems is a daunting task.

Java Platform Security and JAAS

The Java platform is built from the ground up with security in mind. This talk will introduce the security features of the J2SE, building quickly from the basic classes to realistic examples.

JavaScript for Java Programmers

This presentation covers JavaScript from the perspective of a Java programmer. We assume that you may be using an Ajax toolkit, but still need to be able to read, modify, and test the JavaScript code in your application. You will learn the common idioms of JavaScript by looking at working code from Prototype and Scriptaculous.

Programming Java Concurrency

Java has always provided a model for concurrency and threads. With Java 1.5, this model received a major facelift. Learn how to use the new concurrency utilities to build responsive, scalable, and correct concurrent applications.

Spring Dependency Injection

Dependency Injection (DI) is the cornerstone of Spring. The core concept is quite simple, but (surprise!) actual practice can become complex. To take full advantage of Spring DI, you need to understand not only the basics on configuration, but also the container lifecycle model and the various hooks provided by the framework.

Automating Business Value with FIT and FitNesse

The presentation will briefly discuss stories, the origin and authoring of story tests, and a demonstration of how FIT and FitNesse (FIT living within a Wiki) can be used to automate acceptance tests.

Creating, Telling, and Tracking User Stories

The participants of this session will become agile customers and product owners, using personas to create stories for a sample product development.

Losing Battles and Winning Wars: Adopting Agile

Adopting agile is different for each company, but most companies will go through some amount of change during the adoption of agile.

Ready, Set, Agile?

As with many methodologies, moving agile into an organizations poses larger challenges. Before jumping in, it helps to ask a few questions before "racing toward agility". This session will provide 3 tactical steps that can help your adoption of agile.

“Show Me the Numbers” - Agile Planning Tools and Techniques

This session will focus on tools and techniques for tracking an agile project plan from creation to project completion.

Agile Architecture

Traditionally, we attempt to make the right architectural decisions early due to the significant anticipated cost affiliated with making incorrect decisions. But this contradicts agile practices which have taught us to embrace change. So how do agile and architecture come together? Conceptually, the goal of agile architecture must be to eliminate the architectural significance of change by crafting software that can easily adapt to change. In practice, developing agile architecture is much more difficult.

Dependency Management Techniques

Why is software so difficult to change? When you establish your initial vision for the software’s design and architecture, you imagine a system that is easy to modify, extend, and maintain. Unfortunately, as time passes, changes trickle in that exercise your design in unexpected ways. Unlike what you had anticipated, each change begins to resemble nothing more than another hack, until finally the system becomes a tangled web of code that few developers care to venture through. Eventually, modifications to the software intended to improve the system have the opposite affect of breaking other parts of the system. The software is beginning to rot.

Enterprise AOP with AspectJ

Enterprise application development is a gold mine for applications of AOP. There are many crosscutting concerns found in a typical enterprise application, ranging from well-known security and transaction management to application- and technology-specific concerns. Using AOP leads to implementations that are easy to understand and easy to change.

Myths and Realities of AOP

Aspect-oriented programming (AOP) promises to modularize crosscutting concerns. Like all new technologies, AOP has its share of over zealousness and unjustified criticism, neither of which is useful to developers deciding if they should use AOP in their applications. Attend this talk to understand the real deal behind AOP and change your perspective of AOP forever.

Spring AOP in Depth

Support for aspect-oriented programming is an important part of the Spring framework. It is the AOP support that allows keeping implementation of functionality such as transaction management and security out of your POJOs. While many developers only use aspects provided with Spring, once you understand how it all works, you can make a better use of those aspects, extend them, and write brand new aspects.

The State of AOP

A lot is happening in the field of Aspect-oriented programming (AOP). AspectJ and AspectWerkz, the two leading AOP implementations, have merged, bringing in their respective strengths. The merged version, AspectJ 5, adds many new features aimed at simplifying writing and deploying aspects. The new features include an annotation-based and XML-based syntax to define aspects, support for new Java 5 concepts, and load-time weaving. The tools support for AOP continues to improve, as well. Further, the most popular IOC framework, Spring, enables integrating aspects written in AspectJ. There is also serious discussion and preliminary work going on to support AOP right into the VM itself. All in all, there is a lot to learn about the changes in the exciting field of AOP. This session is designed to help you get up to date with all these changes.

J2EE Security @ Work: J2EE Meets JAAS

Have you wasted time writing lots of security-based code and ever wondered if there's a better way to add security to your application? Are you confused by declarative security? Have you read about JAAS (Java Authentication and Authorization Service) but wondered where it fits? Have you ever said, "Can I just see a working example"? If so, then this talk is for you.

Java/EE Web Services and SOA @ Work: Architecture & Development

Have you tried to deploy J2EE Web Services and thrown up your hands in frustration at the lack of tool support? Do you want to know how to develop and deploy Java EE-compliant Web Services so that they work every time? Would you like to see how to develop/deploy Web Services in Spring with XFire? Are you wondering if SOA is just hype and fluff? Do you think SOA is just marketing's re-packaging of Web Services? Would you like to know how Web Services and SOA (Service-Oriented Architecture) fit together? If so, then this talk is for you.

Java/J2EE Architecture @ Work: EJB 3 vs Spring and Hibernate

You've used EJB in the past and been disappointed - it was too heavy and difficult to use. Like Bruce Tate, maybe you've gone from "Bitter" to "Better, Faster, Lighter". With EJB 3 shipping in early 2006, maybe it's time to take another look. We'll compare EJB 3 with alternative frameworks - Spring and Hibernate - to see if EJB 3 has closed the gap.

Applied Design Patterns

Just about every modern software developer has a copy of the Gang of Four "Design Patterns" book sitting on a shelf; many of them have actually read it. The dark secret of the patterns community is that there is often a large gulf between whiteboard simplicity and real-world complexity. Language choice plays a part in the design (and even importance) of patterns. The situation is made even more confusing by the fact that many of the core patterns have now been "voted off the island" for one reason or another. This talk will give a pragmatic overview of the motivations behind design patterns and will focus on applying a handful of the GOF patterns to example scenarios in Java, Ruby and C#. A quick introduction to the role AOP plays in changing the patterns landscape will also be covered.

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.

JmDNS : Easy Service Discovery for the 21st Century

Service-oriented architectures (SOAs) are all the rage. But how do you find all of these services once they are deployed? Configuration files are so 90's. Software of the 21st Century should be able to find related services and components without users having to specify particular configurations at start up. The IETF's ZeroConf multicast DNS protocol was designed to solve exactly this problem. JmDNS is Java-based open source implementation of this capability that allows local-link applications to find and use automagically discovered capabilities. Apple's Rendezvous technology is another open-source ZeroConf implementation behind many of the exciting applications it is building for OS X these days. Come learn how you can interact with these or your own service discovery-savvy applications without even having to learn how to spell UDDI. Bring your wireless notebooks to participate in a service-oriented environment (please have a working Java environment as we won't have time to debug installation issues).

Groovy for Java Programmers

Object-oriented scripting languages, or agile dynamic languages, as some like to call those, are gaining programmers' attention. Groovy bring this excitement to the Java platform with its ability to generate byte code. You can use Groovy instead of Java for some parts of your application. By learning it, you can switch between the languages where you consider fit.

Java 5 Features, What's in it for you?

A number of new features have been introduced in Java. What benefit do these features offer you. Are there issues with using these features. For instance, when should you use annotation? The objective of this presentation is not simply to introduce you to the features, but to the effective use of these as well.

Open Source Tools for Agile Development

As a Java developer, you have taken the time to learn the basics of the language and relevant parts of its rich API. However, you need more than that to develop serious industrial strength applications. In this presentation, the speaker will introduce you to a number of open source tools which you can use to improve your application quality and your development process.

Practices of an Agile Developer

You have worked on software projects with varying degree of success. What were the reasons for the success of your last project? What were the reasons for those that failed? A number of issues contribute to project success - some non-technical in nature. In this presentation the speaker will share with you practices in a number of areas including coding, developer attitude, debugging, and feedback. The discussions are based on the book with the same title as the talk.

Refactoring your code - a key step in agility

Refactoring is one of the core practices in Agile Software Development. Refactoring is based on some core principles that apply to more than writing good code. But, what's refactoring? Why should you do it? How do you go about doing that? What tools are available to successfully refactor your App?

Working with Rules Engines

Rule based programming allows us to develop applications using declarative rules. These can simplify development in applications where such rules based knowledge is used for decision making.

Introduction to Hibernate

O/RM (Object/Relational Mapping) seeks to eliminate repetitive or tedious work enabling the CRUD (create, read, update, delete) that underlies most applications. Hibernate is a popular, open-source O/RM tool that uses reflection (instead of code generation, like EJB, or bytecode injection, like JDO) to manage your persistence layer.

Politics of Persistence

This session will help a Java developer choose a persistence framework. After the session, you will • Understand the core strengths and weaknesses of the main persistence frameworks in the Java space • Understand where marketing influences can impact persistence • Know what’s going on behind the scenes to impact the persistence pictures • Answer questions about persistence frameworks that might not be mainstream

Three Technologies to Watch

The state of the art is progressing rapidly, and dynamic languages are driving the revolution. Find out about these topics that will be central to programming. We'll discuss continuation servers, metaprogramming frameworks and functional langauges.

What's New in Spring 2

In this session, we'll review the new features of Spring 2.0. If you've been using Spring 1.x, you'll want to hear about the improvements.

Where Agile meets Argyle: New processes in established companies

Agile programming is a collection of core principles and techniques that allow software developers to create lighter, more responsive applications, and to have fun doing it. Many established organizations are either openly or sub-conciously hostile to many of the principles of Agile development.

Herding Racehorses and Racing Sheep

Are you frustrated by experts who can't tell you what to do, or by junior team members who refuse to see the big picture? How can you best develop careers: both yours and those of your teammates and managers? How can we learn to apply experience more effectively, and why do the many approaches designed to tame complexity actually end up increasing it?

Ruby for Java Programmers

Ruby recently enjoyed its tenth birthday. Instead of cake and candles, the community celebrated by releasing a wave of new libraries and frameworks that make Ruby programming even easier. This talk features some of the best of these, as we explore Ruby.

Ruby on Rails

The Ruby on Rails framework has exploded onto the scene over the last few months. Propelled by some genuine benefits, and fueled by a whole lot of controversy, Rails seems here to stay. So, is it a Java killer? (No.) Is it a great way to develop certain classes of web application? (Yes.) Does it really deliver the 10-fold increase in developer productivity that some have claimed? (It depends...)

Testing your Rails Application

The Ruby on Rails framework has unit and functional testing baked right in. In this talk we'll see how easy it is to get started with testing in Rails, and we'll explore jut how deep the testing support goes.

Using Ajax with Ruby on Rails

Ajax is becoming a requirement for new applications: it creates richer user experiences and more dynamic applications. However, doing Ajax by hand is difficult and error prone. The good news is that if you use Rails, you don't have to do Ajax the hard way.
