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.

Prior to the release of JDK 5.0, the Java platform provided basic primitives for writing concurrent programs, but they were just that -- primitive -- and difficult to use properly. Building multithreaded applications on the Java platform's low-level concurrency primitives posed many traps for the unwary, and many developers were forced to reinvent the wheel by writing their own classes for thread pools, semaphores, and task schedulers.

To help users create robust, scalable, and (most importantly) correct multithreaded applications, JDK 5.0 includes a rich set of high-level concurrency constructs, such as thread pools, semaphores, mutexes, barriers, and high-performance concurrent collection classes. Using these concurrency utilities will, in most cases, make your programs clearer, shorter, faster, easier to write, and more reliable. This session provides you with an overview of the new high-level concurrency utilities in the new java.util.concurrent package in JDK 5.0.

By Brian Goetz
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.

Based on the principles in the best-selling Java Concurrency in Practice, this talk focuses on design techniques that help you create correct and maintainable concurrent code.

Presented in the style of Effective Java, this talk offers bite-sized items for effectively writing concurrent code, divided into three categories: writing thread-safe code, structuring concurrent applications, and improving scalability.

Writing thread-safe code:
- Encapsulate your data
- Encapsulate any needed synchronization
- Document thread-safety intent and implementation
- Prefer immutable objects
- Exploit effective immutability

Rules for structuring concurrent applications
- Think tasks, not threads
- Build resource-management into your architecture
- Decouple identification of work from execution

Rules for improving scalability
- Find and eliminate serialization

By Brian Goetz
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.

Java was the first mainstream programming language to incorporate a formal, cross-platform memory model, which is what enabled the development of write-once, run-anywhere concurrent classes. It is the Java Memory model that defines the semantics of synchronized, volatile, and final.

However, because the most commonly used processors (Intel and Sparc) offer stronger memory models than is required by the JMM, many developers frequently use synchronization and volatile incorrectly, but have been insulated from failure by the stronger memory guarantees offered by the processor architecture they happen to be deploying on. (The infamous “double checked locking” idiom is an example of this sort of error.)

JDK 5.0 incorporates JSR-133, a revision of the Java Memory Model, which refines the semantics of synchronization, volatile variables, and final fields. Additionally, the new JMM provides a new safety guarantee – initialization safety – that allows immutable objects to be shared among threads without synchronization, if certain requirements are met. This talk describes the updated Java Memory Model for programmers who are familiar with the multithreading primitives in Java (synchronized and volatile.)

Understanding the Java Memory model is key to using the core concurrency primitives (synchronized and volatile) to develop thread-safe, efficient concurrent classes. We’ll cover what a memory model is, what synchronization really means, what was broken about the original Java Memory Model, and how the memory model changed in JDK 5.0.

Transactions are the software building blocks of enterprise applications, but not all transactional systems are created equally. This talk covers the basics of what transactions are, why they are essential to building reliable enterprise software, the fundamental properties of transactions, and how transactions are supported and implemented in popular frameworks such as Java EE and Spring.

Murphy's Law states that anything that can go wrong, will go wrong. And in enterprise applications, there are lots of things that can go wrong -- disks fill up or fail, systems crash, network connections go down, clumsy people trip over power cords. While you can't prevent failures from happening, you can prevent failures from corrupting your application data, and transactions are the standard way to structure application logic to enable reliable error recovery in the face of inevitable failures.

This talk covers what transactions are, the various participants in local and distributed transactions, the role of transactions in enterprise technologies such as Java EE, Spring, and Web Services, how user code communicates its transactional requirements, and the behind-the-scenes magic how enterprise frameworks hide most of the implementation of transactions from applications.

By Brian Goetz
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.

In this class, we'll look at some common Java performance myths, identify where they came from, and explore the platform changes that have rendered them no longer true. Many common performance hacks don't actually help, and some can seriously hurt performance. The result is that clean code that follows common usage patterns generally shows far better behavior on modern JVMs than code laden with tweaks designed to "help" the JIT or garbage collector. More often than not, this well-intentioned assistance has the unfortunate effect of undermining many common JIT optimizations, resulting in slower -- not faster -- code.

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 applications.

This session will be a deep dive into the capabilities of the open source JBoss Enterprise Service Bus 4.2 GA. An ESB is primarily categorized by its capabilties in the areas of protocol mediation/abstraction, transformation, orchestration, routing, endpoint registry, etc. Numerous live demos of ESB functionality.

We will describe in detail those capabilities which define an ESB such as protocol mediation, service registry, transformation, orchestration, content-based routing, and use of popular Enterprise Integration Patterns such as splitter, aggregator, wiretap, translator etc.

By Burr Sutter
At some point, code will be written, software tools will be acquired and systems will be built. Unfortunately the Java development world is a confused mess as it relates to a method of building a Service Oriented Architecture (SOA)-based anything. Our objective is to answer the following questions: Should I use Web Services everywhere? Is an Enterprise Services Bus (ESB) useful and required? Should I be programming in the XML-based syntax of BPEL instead of Java? Do I need JBI and/or SCA? What Open Source implementations are available to solve SOA related challenges?

This session will dive into the actual patterns and code used to SOA "enable" your current applications and skills. Attendees gain insight into techniques and patterns that will allow the typical Struts, Spring & Hibernate developers to move toward the use of SOA. Most importantly, attendees leave this session with practical skills necessary to live in the new Service Oriented world. Students learn to leverage the capabilities of J2EE/Java EE as well as the most popular open source frameworks to create new enterprise integration applications.

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

Let's move beyond getting lucky and look at some key practices that will help you build your scattered cats into a well-oiled machine.

By Jared Richardson
How do you keep a team scattered across time zones in sync?

It's difficult to keep a local team coordinated. When we add geographical distance to the equation, problems are immediately magnified. We'll talk about techniques that you can use to be sure everyone is sharing information and on the same page whether they're in the same office or in different time zones.

By Jared Richardson
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.


In this session, learn five of the techniques I've borrowed along the way. We'll discuss The List, code reviews, code change notifications, daily meetings, and tech leads. These techniques are often abused, but when used properly they can make a huge difference in how you develop software. Take this opportunity to add these practices to your toolkit.

Grails is an open-source web application framework that's all about getting things done. Grails combines best-of-breed Java technologies (including Hibernate and Spring), convention over configuration, and the powerful and dynamic Groovy language. Together with these elements and Groovy's ability to seamlessly integrate with your existing Java code, Grails finally legitimizes rapid web application development for the Java platform.

In this presentation, we'll see first-hand how to use Grails to build a fully-functioning and flexible web application in minimal time. As we develop the application, we'll explore the Grails project structure, its MVC elements, and the power of dynamic methods. We'll see how Groovy's highly-expressive nature allows us to write concise code, and Grails' use of sensible defaults and convention-over-configuration save us from much of the coding and configuration we'd otherwise face with many traditional frameworks.

By Jason Rudolph
Grails provides a tremendous jump-start to any web application. With easy scaffolding and zero-configuration ORM, you're up and running in no time. But what's needed to effectively move from a vanilla Grails project to a fully-customized application fit for public consumption?

In this session, through live demos we'll explore techniques for quickly securing our application, implementing effective (and DRY) UIs, developing Grails services, extending Grails with plugins, and even integrating with Java when the need arises.

By Jason Rudolph
Have you seen someone develop a Rails or Grails application in a matter of minutes, only to later discover that their domain model and database schema followed conventions that are different from your existing systems? Or perhaps you're interested in using Grails, but you don't want to duplicate your existing Java domain classes in Groovy. In this session, we'll see how Grails makes it easy to hook into your pre-defined schemas or existing entity classes, while still getting all the rapid application development (RAD) goodness that Grails has to offer.

In an enterprise environment, you're no doubt surrounded by legacy schemas that pre-date Grails by many years, possibly even a decade or so. You want to develop web applications quickly with one of the next-gen frameworks, but there's no chance that management will agree to change all the schemas just so you can code your app using the conventions employed by the next big thing. However, we'll see that with a bit of Hibernate XML or annotations, we can easily wire together our Grails domain models to our existing schema and still get most of the RAD benefits of Grails, including the super-productive dynamic finders. We'll discuss how to deal with various relationship types, non-trivial primary keys, and other database-related challenges.

In another big business scenario, you may find that you already have EJB3 entity beans lying around, perhaps powering some back-end B2B applications. The time has come to build a web front-end for those applications, and you logically want to reuse your current domain classes. With a few simple steps, we'll see how to use those entity beans as your Grails domain classes, and how your EJB3 domain models suddenly get all the benefits of Grails scaffolding, highly-configurable validation rules, powerful Hibernate criteria builders, and more.

Over the past few years, a lot of time has been spent explaining what JSF is, and how different pieces of it work. However, little attention has been given to the process of architecting applications. This makes JSF architecture seem like a black art, since there are so many possible approaches to the application's architecture.

This session looks at different techniques for structuring JavaServer Faces (JSF) applications, and examines the consequences of each technique. In addition, we will examine extension points within JSF, and how they can be leveraged to provide features such as security, alternate templating technology, and access to external resources. The session ends with some additional tips and best practices.

Prerequisite: Experience with JavaServer Faces.

By Kito Mann
With the emergence of AJAX as a preferred way of building web user interfaces, JavaServer Faces (JSF) has proved itself to be a natural fit for integrating AJAX with Java sever-side logic.



JSF allows you to build AJAX applications without worrying about the complexities of JavaScript and DHTML. However, many different approaches for using AJAX with JSF have emerged. This session looks at these different approaches, the pros and cons, and provides key insight into JSF's future as an AJAX web development platform.

By Kito Mann
JBoss Seam is a popular open-source application framework for Java Platform, Enterprise Edition (Java EE) 5.0. For web application developers, a significant benefit of Seam is that it greatly enhances JavaServer Faces technology. This session explains key Seam features such as tight integration with EJB3, Hibernate and JPA integration, conversations, RESTful web pages, and so on.


This presentation introduces Seam web features from the perspective of a developer on the JavaServer Faces platform. It uses a lot of code examples and demonstrates live applications. It also discusses RAD tools for getting a Seam JavaServer Faces technology-based project started. Developers attending this presentation will leave with a basic understanding of exactly what Seam is, what problems it solves, and how to get started.

Prerequisite: Basic understanding of Java web application development. Familiarity with Dependency Injection/Inversion of Control, JSF, and JPA/Hibernate persistence is a plus.

By Kito Mann
For developers who are currently using Spring and JavaServer Faces together, this session explains how to handle common application development concerns such as conversational scope, transaction management, and application partitioning.

For developers who are currently using Spring and JavaServer Faces together, this session explains how to handle common application development concerns such as conversational scope, transaction management, and application partitioning.

Specific tools such as Apache MyFaces Orchestra and Spring WebFlow will be discussed. At the end of this session, developers will understand how to build a full-stack JavaServer Faces/Spring/Hibernate or JPA application with features similar to those of JBoss Seam.

By Mark Fisher
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 talk will highlight new configuration strategies, Spring AOP, bean scoping, JPA support, JMS improvements, new Spring MVC features, VM languages, and much more.

By Mark Fisher
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.


While ESB is a vast topic, this session will offer a glimpse of a few technologies (scheduling, messaging, and remoting) within the context of an ESB. The content will be heavily example-based with a good deal of code and configuration. The emphasis will be on Spring's enabling role for implementing POJO-based solutions that achieve flexibility in the face of the constantly changing requirements of enterprise integration.

By Mark Fisher
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.

Spring Security's interceptor-based approach is non-invasive even when extended to accommodate domain-specific requirements. The two main security processes (authentication and authorization) are decoupled in order to provide flexibility across a wide variety of providers and strategies. This presentation will include an overview of Spring Security's pluggable authentication process and how it accommodates a wide range of possibilities including Database, LDAP, Single Sign On, and even an in-memory option for development and testing. We will then proceed to cover authorization where you will see its consistent approach for securing web requests and method invocations. Throughout the session, we will walk through a sample application that demonstrates Spring Security's core features.

By Mark Fisher
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.

After a quick overview of Spring's JMS support, we will build a Message-Driven POJO sample application from the ground up. This will include sending a Message as a request and receiving a reply across separate JVMs. You will learn how to configure the Message-Driven POJO without writing a single line of messaging code. You will also learn how to configure the pool of concurrent consumers and integrate with Spring's transaction management. We will use the JMS namespace available as of Spring 2.5, and we will even explore the possibility of delegating to a Groovy-scripted object.

By Muness Alrubaie
Test Driven Development is a central tenet of Agile software development methodologies and is a powerful design technique for any software developer. The reasons for this are many: it encourages more modular, simpler code.
It helps you avoid YAGNI. It can be used to document a software system, by providing a specification and examples of its use. A test suite, is also a necessary safety net for any serious refactoring work.



In this session we'll talk about these aspects of TDD, how it fits with other Agile development practices, what makes up a good test, testing myths and introduce tools you can use to TDD.

By Muness Alrubaie
TDD has been around for a long time. And the tools available to write and use your unit tests continue to improve. Some of the tools we use on a regular basis include JUnit, the most popular testing frameworks, Cobertura, a test coverage analysis tool and jMock, a Mock Objects library that allows you to test the interactions between your objects. Less common, but quickly becoming popular is the practice of writing tests using dynamic languages such as Groovy and Ruby.



Come to this hands-on session and see how you too can harness these tools to write or improve your tests.

By Neal Ford
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.


No subject has been subject to more recent hype than Service-Oriented Architecture (I think it was because of a really good article in an in-flight magazine). For whatever the reason, the CxO has decided that we need one. It's up to you to implement it. This session is all about the technical considerations required to implement a service oriented architecture. It discusses technology choices, what is in (and out) of SOA's scope, how to implement transformations, routing, and other key services, how to version endpoints, and finally testing and debugging SOA. This session is marketecture free: it covers the details you need to implement this style of architecture.

Session Topics:

• What SOA means to those who must implement it
• Technology choices
• Routing
• The WS deathstar
• MOM
• Implementing transformations
• Versioning services
• Testing SOA
• Debugging SOA implementations

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.

It is too easy to get into a coding slump and not realize it. This talk revitalizes your relationship to code, forcing you to rethink some of the thing that you take for granted and showing new approaches to solving hard problems. It covers topics that range from improve the overall structure of your code to the way you write JavaBeans, with lots of examples. Everything in this talk may not be new to you, but I guarantee that you'll see some things that will make you reevaluate the way you think about your code.

Regular expressions should be an integral part of every developer?s toolbox, but most don?t realize what an important topic it is. Regular expressions have existed for decades, but many developers don't understand how to take full advantage of this powerful mechanism, either through command line tools and editors or in their development.

This session shows how to fully exploit regular expressions. It begins with the basic premise of how regular expressions work, then shows how to take advantage of the RegEx library built into the Java platform. This session shows how to use wildcards, escape characters, meta-tags, character class operators, look-aheads/look-behinds, and how to use the greedy operators effectively. It covers regular expressions from the beginning through to advanced usage, both in Java and in tools that support regular expressions. This session is packed with real examples of regular expressions (including a game show with no fabulous prizes).

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.


You've heard all the hype for the past couple of years: Domain Specific Languages (DSLs) are going to take over the world. This session demystifies this topic in 2 ways: by providing concrete definitions for styles and applicability of DSLs and showing how to implement these different styles. I build up definitions for the different types of DSLs in static (Java) and dynamic (Groovy and Ruby) languages. Then, I discuss building DSLs as internal (i.e., built on top of an underlying language) and external (built using a preprocessor or grammar), with examples of each. Throughout this session, I discuss the applicability of this style of development and show targeted examples. I discuss fluent interfaces and techniques for building them, including problems. Incidentally, I show some cool language features of both Groovy and Ruby that make building DSLs easier in those languages.

Session Topics:

• Why DSLs
• Abstraction
• Internal vs. External DSLs
• Fluent Interfaces
• Building Blocks
• Internal DSLs
• In Java
• In Groovy
• In Ruby
• The Stopping Problem
• Best Practices and Applications

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.


In The Productive Programmer, David Bock and I identify 5 principles of productivity: this talk goes into great detail on 3 of those principles. The session defines the principles and describes their use, but the primary focus of this talk is on real-world examples of how you can use these principles to make yourself a more productive programmer. Acceleration covers keyboard shortcuts (including ways to make better use of them) in both IntelliJ and Eclipse. Focus describes how you can modify both the operating system and your code base to eliminate noise. Indirection shows how a simple concept can have profound effects, including how to share a common set of plugins across an entire Eclipse project. This talk includes tons of examples, all culled from real-world projects.

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.


In The Productive Programmer, David Bock and I identify 5 principles of productivity: this talk goes into great detail on 2 of those principles. The session defines the principles and describes their use, but the primary focus of this talk is on real-world examples of how you can use these principles to make yourself a more productive programmer. Canonicality (the DRY principle from The Pragmatic Programmer) discourages repeating artifacts in projects. This talk shows effective ways to avoid this repetition. For example, I show how to reuse documentation via a Subversion hook that posts comments to a Wiki with an RSS feed. Automation refers to making the computer do more work for you. This talk includes tons of examples, all culled from real-world projects.

This session explains all the hype surrounding Ruby on Rails, in a context familiar to Java developers. It covers convention over configuration, ActiveRecord, controllers, views, Ajax, scaffolding, testing, and deployment...on the JVM, using JRuby.

Find out why everyone won't shut up already about Ruby on Rails! This web framework for Ruby has appeared from nowhere to become the critics darling: there must be good reasons why. This session shows those reasons, in a context familiar to Java developers. It discusses how configuration works in Rails, persistence through ActiveRecord, scaffolding, controllers, views, and Ajax. It also covers the important topic of testing, and how Rails makes it easy and automatic. Finally, this session discusses deployment on the JVM, using JRuby, and reflects back on the important lessons that Rails teaches Java developers. This session also presents information about the boundary between Rails, Ruby, and JRuby.

Session Topics:

• Why Ruby? Why Rails?
• Getting started
• JRuby and Rails
• Convention over configuration
• Scaffolding
• ActiveRecord: Persistence done right
• ActionPack
• • Controllers
  • Views
  • Ajax for free
• Testing

By Scott Davis
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.



In this presentation, we take a very pragmatic "prove it in code" approach to learning Groovy. Since the syntax is (almost) identical to Java, we can dive right in from the very beginning, learning the "syntactic sugar" as we solve real world problems.

You'll learn how easy it is to install Groovy and get started working with it. You'll tackle file I/O, reading and creating text files. You'll create and parse XML and HTML. You'll interact with databases. You'll create Groovlets (servlets sprinkled with Groovy-dust). And finally, you'll get a brief introduction to Grails (hint: the 'G' is silent).

By Scott Davis
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.


We'll look at calling Groovy from Java. We'll look at calling Java from Groovy. We'll look at compiling Groovy code, JARring it up, and deploying it alongside Java.

Groovy offers the same level of integration with Ant. We'll look at Ant tasks that allow you to include Groovy in your build process. Or maybe you'd prefer to use the Groovy AntBuilder and completely manage your build in code. The choice is yours. The important thing is Groovy works along side your familiar toolkit instead of forcing you to replace it.

GORM (the Grails Object/Relational Mapper) is one of the many high points of the Grails web framework. GORM is a thin Groovy wrapper over Hibernate, but that doesn't begin to capture excitement of what GORM brings to the party. Imagine being able to call book.save() and book.delete() on your Book class; calling Book.get(1) to retrieve your book from the database by primary key; using Book.list() to pull an ArrayList of Book objects into your application. Now imagine getting all of that functionality (and more) for free with each new class you define. No interfaces to implement. No abstract classes to extend. Persistence that is transparent, automatic, and simple to use: GORM.

Querying your data via GORM is a case study in the benefits of using a dynamic language. Queries like Book.findByAuthorAndTitle("Scott Davis", "Groovy Recipes") rule the day. For the really hard stuff, you can always get back to a more traditional SQL-based interface. We'll also explore Query-By-Example.

GORM allows you to model your objects in the database in a variety of ways. In addition to supporting the usual 1:M, 1:1, and M:M relationships, GORM allows you to flatten the model, breaking traditional normalization rules. (Just don't tell your DBAs about it...) Come see how GORM handles HashMaps, Arrays, and ArrayLists in your Groovy objects.

GORM can auto-generate your database schema from existing POGOs, but recognizes that not all development is greenfield development. GORM allows you to map existing tables to objects and arbitrary field names to POGO attributes. We'll also see how to bypass Hibernate altogether using EJB3 annotations.

If you are a Hibernate developer, you owe it to yourself to see how GORM makes a good thing even better. If you are a Groovy/Grails developer, come see how to get the most of your friendly neighborhood persistence framework.

"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..."

In this humorous keynote, Scott Davis turns to unconventional sources for enlightenment. Could best-sellers like Blink, Freakonomics, The Tipping Point, The Paradox of Choice, and The Wisdom of Crowds finally solve the puzzle? In this "Da Vinci Code"-like romp through the conventional wisdom of the day, will the Holy Grail of web frameworks be revealed? Probably not, but possible side effects may include nausea, dry mouth, and insight into the eternal question of our industry.

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 tow
