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.

Portal Standards and implementation

Portals and Portlets allow you to personalize your web application. However, developing and deploying portlets across different portals can be a challenge. What is WSRP and JSR-168. How are these related and how are these different? Are these competing technologies or do they work with each other?

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.

Applied AOP

Most people new to Aspect-Oriented Programming (AOP) are fed up with separation of concerns zealots explaining how great their techniques are at dealing with... logging. Ok, you get it. Logging is a cross-cutting concern that can be appropriately modularized. What else does AOP have to offer? A lot, it turns out. This talk will give an introduction to the motivations of AOP as well as a series of concrete examples drawn from enterprise and client side Java. Come learn how AspectJ-flavored AOP can begin to benefit you immediately either in development or production environments. Learn how to enforce architectural policies, find Swing threading issues, reduce the invasiveness of the Observer design pattern or even improve the reusability of your domain models. Now that Spring 2.0 provides support for AspectJ, the time has never been better to learn about these new (but backwards compatible) ways of thinking about building software.

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.

Introduction to NetKernel : Software for the 21st Century

Imagine the simplicity of REST married to the power of Unix pipes with the benefits of a loosely-coupled, logically-layered architecture. If that is hard to imagine, it may because the architectures available to you today are convoluted accretions of mismatched technologies, languages, abstractions and data models.

NetKernel is a disruptive technology that changes the game. It has been quietly gaining mind share in the past several years; people who are exposed to it don't want to go back to the tired and blue conventions of J2EE and .NET. Not only does it make building the kinds of systems you are building today easier, it does it more efficiently, with less code and a far more scalable runway to allow you to take advantage of the emerging multi-core, multi-CPU hardware that is coming our way.

Come see how this open source / commercial product can change the way you think about building software.

Java5: The Language, The Libraries, The VM

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.

Effective Enterprise Java: State Management

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-.

Pragmatic XML Services

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.

The Busy Java Developer's Guide to JVM Scripting

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.

Pragmatic Extreme Programming

This session talks about how to actually get XP done in the real world (and what to tell your boss).

Real-world Agile Development

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.

SOA: Next Wave of Enterprise Development or Return of the Son of CORBA?

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.

The Productive Programmer

This session shows you how to become a more productive programmer every day by using tools that you didn't know you already had.

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.

All Roads Lead to.. AOP?

An exercise in refactoring, playing with Java 5 annotations, varargs, JUnit, and more (see detail description for more).

Hibernate by Example

This talk covers the core of the Hibernate Object/Relational Mapping framework by example; that is: in a hands-on manner.

Naked Objects Applied

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.

XML Data Binding with JiBX

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.

Business logic organization and encapsulation strategies

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.

Comparing EJB 3 with Spring and Hibernate

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.

Developing Rich Domain Models

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.

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.

Introduction to Tapestry 4

An introduction to the Apache Tapestry web application framework, which will explain the concepts and features of the framework with some simple applications. We'll discsuss Tapestry forms, request cycle, component object model. The use of several important components, including BeanForm and Table will be highlighted, along with meta-programming using the Trails framework.

Pragmatic Unit Testing with TestNG and EasyMock

You've heard about unit testing but were daunted when it came time to put the pedal to the metal. That's because JUnit is just one tool and there's others you need to learn about, including the wonderful and wierd EasyMock and the easy and powerful TestNG.

Tapestry In Action (Part Two)

In Tapestry, components are not an add-on; in fact, anything but! Tapestry components are integral to the entire framework ? if something dynamic is going on in a page, there's a component involved.

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.

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 AOP

Learn to use Spring AOP, aspect injection. and AspectJ integration

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.

Spring Fundamentals

The Spring framework is one of the fastest growing open source frameworks. New job postings are gaining rapidly, and many customers are adopting Spring instead of heavier alternatives. In this session, we’ll introduce Spring. You’ll see how Spring can give you much of the power of EJB, without the complexity or pain.

Spring Security with ACEGI

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.

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.

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.

Ajaxian JavaScript Frameworks

In the "Introduction to Ajax" session, we discuss what Ajax is, how it works, and how others are using it.

This session goes deeper into Ajax by reviewing the existing JavaScript frameworks that aim to make it easier.

Eight Tips for Swing Development

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.

Introduction to Ajax

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?

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.

An Introduction to User Stories for Software Requirements

The technique of expressing requirements as user stories is one of the most broadly applicable techniques introduced by Extreme Programming. User stories are an effective approach on all time constrained projects, not just those using XP.

Managing Agile Projects: Dispelling the Myths

There is a myth that agile projects do not need project management and that they cannot be estimated and planned. In this session we will dispel those rumors and learn why the job of the agile project manager is to do more than just buy pizza and get out of the way.

Overview of Agile Estimating and Planning

Estimating and planning are key skills. A good plan helps both the organization and the developers working on the project. In this session you’ll learn how an easy and effective approach to estimating and planning that can help you create more realistic plans.

Project Economics: Selecting and Prioritizing High Value Projects

Almost all of us have worked on too many projects that have failed because of economic reasons rather than technical reasons. Just as the technical team is required to estimate the effort that will go into a project, a marketing or product management team should estimate the benefits of doing the project. Benefits can come in the form of additional sales, increased customer retention, increased operating efficiencies, and so on.

Salvaging Struggling Projects: Digging for Gold Instead of Digging a Deeper Hole

Projects struggle for many reasons—overly aggressive deadlines, unproven technologies, scope creep, team dynamics, communication problems, and inter-team coordination are just some of the reasons. If not given attention, these problems can ultimately cause a project to fail entirely. However, if you act early and in the right way, most struggling projects can be turned around.
