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...
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.
Neal Ford - Application Architect at ThoughtWorks, Inc.
This session delivers 10 techniques for improving your code, whether you are freshly graduated or a grizzled veteran.
This session shows how to use Java as the building block for domain-specific languages. It discusses the next revolution in programming: language-oriented programming and the nascent tools that support it.
Lots of developers want to use Agile development technique but don't know where to start. This session discusses how to get started with Agility, the key benefits you can expect, and the pitfalls to avoid.
Is Service Oriented Architecture the next wave of distributed computing or just the same old crap in a shiny new package? This session provides an overview of what most people agree is the definition of SOA. I talk about SOA, ESB, CORBA, your MOM, and a bunch of other acronyms.
This session describes the use and workings of Selenium, the open source web user interface testing tool.
This session shows you how to become a more productive programmer every day by using tools that you didn't know you already had.
Ben Galbraith - Book author, Ajaxian-at-Large, and Consultant
In the "Introduction to Ajax" session, we discuss what Ajax is, how it works, and how others are using it.
Java's Swing GUI toolkit is one of the most powerful and flexible frameworks available for creating professional, high-quality desktop applications. Along with its considerable abilities, however, comes considerable complexity. Swing does not have a reputation for ease of use (despite being much easier than many of its competitors--but that's another story). If you could combine the Swings power with the productivity of easier, more restrictive tools, such as Microsoft's Visual Basic - you'd have an incredible tool for application development.
Ajax -- called DHTML just a few months ago -- has revolutionized (or "radically iterated", if you like) web application development in the short few months since the term was coined.
What is it all about? Why are we excited about a set of capabilites that have been sitting in our browser for years? What can you do with it? And, how can you do it?
David Geary - Author of Graphic Java, co-author of Core JSF, member of the JSF Expert Group
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.
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
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.
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.
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:
There's a lot of cool stuff in Shale that makes JSF a much more compelling proposition. Come see what it's all about.
Justin Gehtland - Founder of Relevance, co-author of Better, Faster, Lighter Java
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.
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. This session will introduce you to Hibernate. After an overview of common usage scenarios, including web and enterprise applications, we'll examine the basics of getting Hibernate running. We'll cover the mapping file format and syntax, including common relational mapping structures. Then, we'll examine the Hibernate API for interacting with the framework. Finally, we'll cover the common architectural decisions you'll have to make as you include this (or any other) O/RM framework.
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. You will learn the core APIs: SecurityManager, AccessController, Permissions and Policy JAAS Subjects, Principals, and LoginModules
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.
Learn to use Spring AOP, aspect injection. and AspectJ integration.
Spring provides powerful support for Aspect-Oriented Programming (AOP), via
Spring Advisors Dependency Injection for Aspects Integration with AspectJ
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.
Spring offers developers a simpler, more robust method for configuring applications. These benefits extend to security through the ACEGI framework. ACEGI makes the otherwise daunting task of securing your application logical and straightforward. More importantly, through its support for single sign-on provision through Yale's CAS system and its ability to provide instance-level authorization, Spring extends the common security model of most J2EE apps beyond what they are traditionally capable of.
Ted Neward - Enterprise, Virtual Machine and Language Wonk
Java5 introduced a whole slew of new features, including annotations (JSR 175), new language features (the enhanced for loop, generics, static imports, and more), new library support (java.lang.instrument, among others), and some interesting enhancements to the virtual machine itself.
Managing state--both transient state (like your shopping cart) and your durable state (like your order placements, your inventory management forms, and so on)--is tricky in an enteprrise application. In this talk, we'll examine some of the trickiness, both high-level and low-.
There's a lot of talk about web services, and most of it falls into one of two categories: lots of low-level talk about vendor-specific tools and extensions, or lots of high-level talk that never shows you a line of code. XML services aren't that hard, and in this talk, we'll see how, why and when to do one.
Ever wished you could just put parts of your program in end-users' hands and let them build the infinite little changes they want? Ever thought about how you might make your application more robust by writing less code, not more? Embed a scripting engine into your application--complete with the safeguards necessary to ensure that users can't do anything they shouldn't be able to--and release yourself from the Principle of Perpetual Enslavement.
Rebecca Parsons - Vice President of Global Innovation - Thoughtworks
Agile development is often talked about in terms of small teams of developers creating massive amounts of code. Such scenarios strike fear into the hearts of "Enterprise Architects". This talk addresses the issues of how agile development and enterprise architecture can not only co-exist with but participate in an agile development effort.
There are many well known tools and approaches in the Java and C# world for unit testing and Test Driven Development or Behaviour Driven Development. Extending these concepts in the EAI world is more of a challenge.
Chris Richardson - Author of POJOs in Action
Key to making good design decisions is knowing the available options and understanding their respective benefits and drawbacks. This presentation looks at two important design decisions that you must make when developing the business logic for an enterprise Java application: how to organize the business logic and how to encapsulate the business logic.
The first part of the talk describes the two main ways to organize business logic: an object-oriented design (a.k.a domain model) and a procedural design (a.k.a. transaction script). You will learn how to implement the business logic using each of these approaches and which lightweight frameworks to use. We will cover the criteria that you can use to decide between the two approaches.
The limitations of EJB2 led to the development of the extremely popular Spring and Hibernate frameworks. These frameworks replaced the cumbersome EJB2 programming model with a nimble, non-invasive Plain Old Java Object (POJO) –based model. But, now, the EJB3 specification has embraced many of the ideas made popular by Spring and Hibernate including POJOs, transparent persistence and dependency injection.
Object-oriented design (OOD) is good way to tackle the complexity of modern applications. Yet many complex, enterprise Java applications are written in a procedural style. One reason is because EJB2 created too many obstacles to using object-oriented design techniques. Fortunately, enterprise Java technologies have improved. Plain Object Java Objects (POJOs) and object/relational mapping frameworks such as Hibernate, JDO and EJB3 led to the revival of OOD.
Venkat Subramaniam - Founder of Agile Developer, Inc.
Agile development is picking up steam. You have heard about eXtreme Programming(XP). What other Agile methodologies are you familar with and what do they bring of interest or significant to the table of Agility? More important, why should you learn about these different methodologies instead of simply focusing on one? There is no one shoe that fits all. Any methodology that requires you to follow it in totality and not let you adapt is rather dogmatic, not pragmatic. To be effective we have to take the best of different approaches and apply to our projects base on our specific needs.
Inspired by the Ruby on Rails project, Grails brings the ease of web development and "convention over configuration" to the Java platform. We will learn how to create web applications using Grails, how to integrate it with Hibernate, and how to Ajax it, all using the built in features of Grails. This section assumes that you are familiar with Groovy or you have attended the “Groovy for Java Programmers” session. The session will be example driven with live coding where we will build a web application from scratch.
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.
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.
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.
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 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?
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.

Today, the Cascading Style Sheets (CSS) specification is well supported by the major browsers (Mozilla, Safari, IE). CSS has become a practical tool for web content publishers that has helped turn heavy, buggy, and hard-to-maintain web sites into lean, clean, and stylish ones. CSS is sometimes stereotyped as a technology geared for graphic designers and artists. I beg to differ: I see CSS as a refactoring tool for content publishers and one that encourages content to become more strongly semantic. Come see a developer's perspective on CSS and how it can be applied to refactor your web content.
This talk covers the core of the Hibernate Object/Relational Mapping framework by example; that is: in a hands-on manner.
Join Eitan in this hands-on session on Naked Objects. This session uses the "learning by doing" approach to learning an API or framework. Naked Objects is a powerful tool that can give you a significant advantage in the development of business systems. It gives you the ability to prototype a software application so quickly that it can be performed during information gathering phases of a project. It gives you the power to codevelop the core business model of your application with a non-developer business expert at your side. No prerequisite knowledge of Naked Objects is required.
JiBX is an open source XML data binding API for Java. JiBX is younger than most other APIs in this space (Castor XML, BEA XMLBeans, JAXB). JiBX's philosophy on data binding is that: [a] databinding should be fast, and [b] databinding frameworks should allow for the divergence and evolution of your codebase from its xml representation. JiBX excels on both counts and consequently is a practical tool for the purpose of data binding. In this session, Eitan will be covering all aspects of Dennis Sosnoski's JiBX framework.
Glenn Vanderburg - Chief Scientist, Relevance Inc.
The Java Collections framework is a cornerstone of Java development. It's been a part of J2SE for six years now. Every Java developer knows it—how to create Lists, Maps, and Sets, how to put things into them and take things out, and how to iterate over the contents. But there's a lot more to the collections framework than that -- and very few programmers really know how to exploit the power that's just under the surface.
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.
The support infrastructure for your software project is a crucial factor for success. A new generation of tools offers significant benefits over their predecessors. This talk discusses how to choose the right mix of tools for a top-shelf project infrastructure.
