Advanced Techniques With Grails

Grails represents technology that offers great flexibility and power without the complexity introduced by other Java web application frameworks. Custom tag libraries are a snap. GSP Templates provide a simple mechanism for reusing UI elements. Sitemesh is integrated to help provide a consistent presentation across the entire application. Grails provides simple mechanisms for leveraging the power of Ajax.

Introduction To Agile Web Development With Grails

Grails brings the powerful "coding by convention" paradigm to Groovy and Java. Grails is not just another flavor in the pool of web development frameworks for Java. Grails leverages the powerful dynamic features of Groovy while taking advantage of best of breed technologies like Hibernate, Spring, Sitemesh and Quartz to make web application development both fun and easy.

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: 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.

KEYNOTE: No, I Won't Tell You Which Web Framework to Use: or The Truth (with Jokes)

"Which framework should I use?" is the question most often heard on the No Fluff, Just Stuff tour. It's well worth asking. Unfortunately, there is no simple answer. After years on the tour, most speakers have crafted a response that would make any Washington politician proud -- long on style, but essentially, "Well, it depends..."

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.

Advanced Selenium

This session discusses advanced Selenium techniques for testing web applications. It discusses techniques for both TestRunner and Remote Control Selenium, including data driven tests, creating branch points, testing Ajax applications, creating flexible tests, integration with continuous integration, and tons more.

Building DSLs in Static and Dynamic Languages

This session discusses building Domain Specific Languages and DSL-style code in Java, Groovy, and Ruby. It discusses the different types of DSLs, details on how to implement them in Java, Groovy, and Ruby, and example problem domains where DSLs make sense.

Code Metrics & Analysis for Agile Projects

What does code + methodology have to do with one another? Everything! Agile projects focus on delivering working code, and tools exist to allow you to verify some quality metrics for your code. This session is a survey of tools and metrics that allow you to determine the quality of your code and strategies to "wire it" into your agile project.

Debugging and Testing the Web Tier

As out applications have spilled from the server across the wire to the web tier, we increasingly must debug and test in the browser. This session covers debugging and testing tools for clients, JavaScript, and Ajax.

Implementing SOA

This talk avoids SOA hype and gets to the meat of the matter: how do you implement a Service-Oriented Architecture, what are the technological pitfalls, how do you test it, and what traps should you avoid. No marketecture: just implementation details.

Productive Programmer: Acceleration, Focus, and Indirection

This session discusses how to use the Productive Programmer principles of acceleration, focus, and indirection to become a more productive programmer. This session describes these principles, but the primary focus of this session is demonstration of these principles with real-world examples.

Productive Programmer: Automation and Canonicality

This session discusses how to use the Productive Programmer principles of automation and canonicality to become a more productive programmer. This session describes these principles, but the primary focus of this session is demonstration of these principles with real-world examples.

The Productive Programmer: Practice (10 Ways to Improve Your Code)

No one writes perfect code: even the best developers fall into bad habits and traps. These topics from The Productive Programmer illustrate blind spots and helps you write better code.

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.

AOP and JMX: A match made in heaven

You're winding down a project and you get that dreaded email from your project manager, "How hard would it be to add some performance monitoring to the system?" Well, after this session, you'll be able to respond, "No problem at all!" It turns out that with a pinch of AOP and a dash of JMX, you can introduce amazing management and monitoring capabilities without changing your mainline code one bit.

Acegi Security: The security framework with the funny name

Security is one of the major requirements in modern day enterprise applications and yet it is also one of the weakest parts of most developers toolboxes. The problem is of course that security is HARD! It turns out that rather than reinventing the wheel for each application, developers can turn to a great security framework out there already; Acegi.

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.

Spring and Hibernate in the Middle Tier

To today's JEE developer, there are two indispensable tools for creating applications; Spring and Hibernate. Together these two frameworks comprise one of the most powerful and often used stacks in the industry. While it is possible to do amazing things it's not always obvious how best to use them to maximize value. This session aims to correct that.

Forgotten Web Algorithms

In this talk I'll explain -- without any needless math or boring proofs -- several fun algorithms of interest to back-end web programmers. Each algorithm was selected because it's really practical, really interesting, or both. The algorithms aren't always the same but can include: public key cryptography, credit card checksum validation, TCP Slow Start, two's complement, priority queues, the XOR swap, and the Google MapReduce function for massively distributed calculation.

Web Publishing 2.0

If we're moving toward Web 2.0, what does that mean for online publishing? In this talk I'll answer that question. Based on my experience as Principal Technologist at Mark Logic working with dozens of the largest online publishers, I'll present a vision for how the Web 2.0 concepts like personalization, collective intelligence, the long tail, and the importance of "owning the data" can and should reshape the face of online publishing -- and how XML, XQuery, and XML-aware text search act as the key enablers. I'll also introduce new Web Publishing 2.0 concepts like "Sweat the content" and "Give answers not links".

What's New in Java 6

The Java 6 (Mustang) release should make your life easier, for a change. It doesn't alter the core language like Java 5 did. It doesn't pack in so many sub-JSRs that you'll be overwhelmed by the amount you have to learn. Instead Java 6 adds several handy things that honestly should have been added before. Among the improvements we'll cover in this fast-paced class:

• A new Console class
• A real Compiler API
• A GIF writer
• Pluggable Locale data
• Access to disk partition size data
• Array reallocation
• Low-level floating point functions
• Reflective access to parameter names
• Access to network interface details
• Pluggable annotation processing
• Improved class file format
• Streaming XML with StAX
• A new Scripting interface

XQuery By Example: Building an Email Archive System

The classic searchable email archive system is cluged together -- a frankenstein monster combining a relational database with a search engine, with Java just barely able to keep the two together. In this talk we'll demonstrate how email is more content than data, how it's better encoded in XML rather than relational tables, and how Java can convert emails to XML and drive an XQuery backend to produce a simpler and more scalable email archive system.

The Busy Java Developer's Guide to ClassLoaders

If you've ever gotten a ClassCastException and just knew the runtime was wrong about it, or found yourself copying .jar files all over your production server just to get your code to run, then you probably find the Java ClassLoader mechanism to be deep, dark, mysterious, and incomprehensible. Take a deep breath, and relax--ClassLoaders aren't as bad as they seem at first, once you understand a few basic rules regarding their operation, and have a bit more tools in your belt to diagnose ClassLoader problems. And once you've got that, and hear about ClassLoaders' ability to run multiple versions of the same code at the same time, and to provide isolation barriers inside your application, or even compile code on the fly from source form, you might just find that you like ClassLoaders after all... maybe.

The Busy Java Developer's Guide to Debugging

Bugs? We all know your code has no bugs, but someday, you're going to find yourself tracking down a bug in somebody else's code, and that's when it's going to be helpful to have some basic ideas about bug-tracking in your toolbox. Learn to make use of the wealth of tools that the Java Standard Platform makes available to you--tools that your IDE may not know exist, tools that you can make use of even within a production environment.

The Busy Java Developer's Guide to Java Platform Security

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.

The Busy Java Developer's Guide to Reflection

If you've never used Reflection (java.lang.reflect), you don't know what you're missing. In this presentation, we'll take a code-first, soup-to-nuts look at the Java Reflection APIs, from how to examine the class metadata that Reflection provides, to using annotations to enhance that metadata with your own information, even through the use of Java Dynamic Proxies to create flexible object "interceptors" that can layer services in front of ordinary method calls with nothing more complicated and an interface and a factory.

Agile Software Testing Strategies

Creating and maintaining a solid automated test suite is critical to an Agile strategy, but often we're just told to "Do it." In this talk we'll look at several pragmatic strategies for creating and building your suite.

Build Teams, Not Products

A great team builds great software, but how do you build a great team?

Continuous Integration with Cruise Control

Continuous Integration is increasingly recognized as a vital practice in an Agile software shop. Traditionally it's been difficult to set up and administer. Today, that's no longer the case.

Gradual Agile: The Secret to Introducing Agile Practices

Agile practices are popular because they work, but getting people to take that first step can be tricky.

Shippers Unite!

An overview of the Agile software approach from the book Ship It! A Practical Guide to Successful Software Projects.

Software Development Techniques

Throughout our software careers we learn habits from our coworkers, from books we've read, and occasionally, from conferences we attend. Much of our competence comes from the tips and tricks we pick up as we go.

10 ways to use Hibernate effectively

Learn 10 tried and true ways to improve the way you use Hibernate today. In this session you would learn about a collection of 10 tips, tricks, practices and tools that will make you more effective at designing, implementing, testing and tuning your application's Hibernate-powered object-relational layer.

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.

Designing for Ajax, part 1

So you've convinced the boss that your new web application just has to have Ajax...but now what? With dozens of libraries making even the most blinkish of interactions trivial, how do you decided where to sprinkle the magic Ajax dust? This talk will give a plain old boring "web 1.0" an Ajax facelift with a focus on improving the user experience providing you with a game plan for introducing Ajax to your world.

Dynamic Languages and the JVM

With all the attention being paid to Ruby and it's hip cousin Rails, many in the Java camp may be feeling like their party invitation is "lost in the mail". Fear not loyal Java lovers, the dynamic language meme is alive and well in your space! Between numerous JSRs and various languages, the JVM is becoming quite the dynamic disco. After an overview of what it means to be dynamic, this talk will look at JRuby, Groovy, and Rhino.

Test Infecting the Legacy Organization

When starting a new project, most developers make sure that testing is a priority. However, only the lucky few live in the idyllic world of greenfield development; the vast majority of us must contend with code written when "test" was a four letter word and testing was the sole responsibility of that "other" organization. We'll examine some techniques for introducing testing - not just to your code but to the rest of your development organization.

Annotation Hammer

Annotation is an interesting feature in Java. However, like any features, there are good uses and bad uses. When should you use Annotation? This presentation will answer that question for you.

Domain Driven Design

Domain Driven Design (DDD) is an approach that places emphasis on the domain model and carrying it into implementation. DDD is mostly repackaging of fundamental OO Design. It brings new emphasis to what we should be already doing, but often find it hard and confusing given the realities and complexities of our real world. In this presentation we will take a close look at what DDD is and how to use it for agile development. We will discuss several design options, and also look at some examples of good modeling and layering.

Drooling with Groovy and Rules

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.

OSGi: A Well Kept Secret

In this presentation we will introduce OSGi and discuss how it can help modularize and version your enterprise Java applications.

get Fit

Unit testing tells you, the programmer, that your code (and the change) meets your expectations. How do you know if you are meeting your customers' expectations? Agile development is all about feedback and doing what's relevant to the customers, isn't it? Framework for Integration testing or Fit helps you to automate tests for customer expectations.

Building ChangingThePresent: Agility in Action

ChangingThePresent is the increasingly popular charity donations portal that lets you give donation gifts instead of another pair of fuzzy slippers. The site is built and maintained under unusual circumstances. The team is distributed, with no more than two developers in any one place. The team uses agile techniques such as automated testing, heavy customer involvement, and a SCRUM-like release plan to deliver the core features.

Rails for Java Programmers

The productivity of Ruby on Rails cannot be denied, but the explosion of Ruby on Rails left many developers, with hard commitments to Java deployment platforms, out in the cold. The continued evolution of JRuby can change that. JRuby is a Ruby implementation on the Java virtual machine. And yes, it runs Rails. In this session, you will learn Rails as it was meant to be learned, within the context of building a live site, from scratch.

Ruby for Java programmers

With the explosion of Ruby on Rails and the Java community interest in features like closures and continuations, the Ruby programming language is an excellent one for all developers to know. As the JRuby virtual machine picks up steam, Ruby becomes a must language to understand. The best way to learn Ruby is to see it in action.
