Pete Behrens - Organizational Agility Coach
Business leaders and stakeholders require accountability and accuracy in our software release projections and yet, as an industry, we have failed. However, many of these same leaders are not convinced that agile is any more than an excuse to avoid projections at all. While it is true that agility provides the framework to support change, it doesn't mean you can't provide accurate projections. In fact, a well-executed agile process actually provides more accurate results with less time investment than traditional methods. This session will demonstrate these agile project management techniques to manage 6-12 month projects.
This session focuses on the release level, followed by Part II which focuses on the sprint level.
Are you being asked to measure your agility? How productive is your team? What is the quality of your product? How accurate are your estimates? Be careful, you will get what you measure.
This session will evaluate metrics which attempt to measure productivity, quality, esimation accuracy, value, and return on investment within the context of an agile project. What measurements are teams using and why? We will explore various measurements used by session participants and discuss some of their pros and cons.
Scott Davis - Author of "Groovy Recipes"
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.
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.
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.
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.
Neal Ford - Application Architect at ThoughtWorks, Inc.
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.
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.
This session describes JRuby, the 100% pure-Java implementation of the Ruby programming language. It covers the basics of programming with JRuby and examples of how to integrate it into existing Java projects.
About bridges, languages, engineering, polyglot programming, and the near future.
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.
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.
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.
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.
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.
David Geary - Author of Graphic Java, co-author of Core JSF, member of the JSF Expert Group
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.
A continuation of a 2-session presentation on Seam, Facelets, and Ajax4jsf.
The second part of a 2-session presentation on the Google Web Toolkit.
Ben Hale - Cloud Foundry Java Experience Engineer
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.
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 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.
Have you ever developed a web application with a long user action based on form input? Did you curse the Java community for their inability to address this very common application type? Well, attend this session about Spring Web Flow and you'll curse no more.
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.
Ted Neward - Enterprise, Virtual Machine and Language Wonk
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.
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.
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.
If you've been keeping your ear to the ground, you may have heard some talk recently about "rules", "business rules" and "rules engines", but not necessarily any clear discussion on what they are, how to use or design them, or why they might be useful or important.
Brian Pontarelli - Founder of Inversoft
Writing APIs is fairly easy but writing an API that is usable and lives longer than a few days is hard. This talk discusses methodologies, tips and tricks for writing good APIs.
Mark Richards - SOA and Integration Architect, Author of Java Message Service
This session picks up where the Intro to JPA session left off and covers some of the more advanced topics in the Java Persistence API. Some of the topics covered in this session include switching persistence providers, versioning, compound keys, entity inheritance, and finally handling both simple and complex stored procedures. Some knowledge of JPA is recommended for this session as I will not be covering the basics of JPA (that is covered in a separate Intro to JPA session). Through a combination of slides and interactive coding I will demonstrate these advanced topics using both Hibernate and Toplink JPA.
EJB3 (JSR-220) offers some great improvements over the prior EJB specs in terms of development simplicity and new features. In this session we will explore in detail some of the new features of the core EJB 3 specification. Included in this session will be a hands-on discussion and demonstration of session beans, dependency injection, interceptors (aop), and Message-Driven Beans (MDB). For the interceptors discussion I will be showing how to define interceptors for enabling a method trace, mocking objects, and sending JMS message notifications to be later picked up by the MDBs I will be creating. During the session I will demonstrate the new features of EJB 3 through interactive coding examples. Note: this session does not cover the new Java Persistence API (JPA) - only the core specification.
In addition to providing a simplified API, the new EJB3 specification (JSR-220) defines a standard ORM Java Persistence API (JPA) that is rapidly gaining in popularity. As you will see in this session, JPA bears a striking resemblance to popular ORM solutions like Hibernate and Toplink. In this session we will explore in detail the new Java Persistence API offered by JSR-220. We will start by discussing the overall design and architecture of the JPA and how the major components within JPA interact. We will then look at defining mapping objects (entities) and how to use the EntityManager to manage these entities. Through interactive coding examples we will investigate the pros and cons of detached entities and merging, how to map and use entity relationships (1-1, 1-N, N-1, and N-N), discuss Lazy Loading, and finally see how to use XML mappings rather than annotations. More advanced features of JPA will be covered in a separate session.
Java Persistence has come along way since the days of straight JDBC coding and custom framework development. We have at our disposal several outstanding open source frameworks such as Hibernate, Toplink, iBatis, and OpenJPA (just to name a few), and we now have a promising and emerging standards-based solution called Java Persistence API (JPA). However, all to often we find in the Java persistence space that it is a world of one-size-does-not-fit-all. We continually struggle with traditional ORM solutions like Hibernate when it comes to reporting queries, complex queries, complex relationships, and stored procedures, and we also struggle with managing the enormous amount of SQL required for solutions such as iBATIS or JDBC-based frameworks. In this coding-intensive session we will take a detailed look at identifying and overcoming the challenges we face when using frameworks such as Hibernate, iBATIS, and JPA, and how to combine the various persistence frameworks to create an effective Java persistence solution that approaches (but of course does not reach) the silver bullet.
As companies continue to change the way they do business, so must the IT systems that support the business. Changes due to regulatory requirements, competitive advantage, mergers, acquisitions, and industry trends require flexible IT systems to meet the demands of the business. Software Architects must therefore make their architectures more agile to meet the flexible demands of today's business. Through real-world examples and scenarios we will explore some of the challenges facing Software Architecture and discuss several concrete techniques for applying agility to both the architecture process and the technical architecture itself. We will also look at various architecture refactoring techniques, and discuss the pros and cons of each. By attending this session you will learn how to apply various agile techniques to improve your architectures and overcome some of the challenges facing software architecture in today's ever-changing market.
There has been a significant amount of buzz in the community and industry about the definition and role of an Enterprise Service Bus (ESB), particularly within the area of Service-Oriented Architecture (SOA). In this product-agnostic high energy session we will take a step back and consider whether we really need an ESB. Through real-world application and architecture scenarios we will see where an ESB would be helpful and where it would be overkill. We will take a look under the hood and find out just what an ESB is really doing, and take a quick look at JBI (JSR-208) and see the impact it has on the ESB worls. Then, using product-agnostic coding examples we will learn what an Enterprise Service Bus is supposed to do, then answer the question about whether the ESB is just a bunch of hype or if we really need it.
Jared Richardson - Agile coach and co-author of Ship It
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.
A great team builds great software, but how do you build a great team?
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.
Agile practices are popular because they work, but getting people to take that first step can be tricky.
An overview of the Agile software approach from the book Ship It! A Practical Guide to Successful Software Projects.
Graeme Rocher - Grails Project Lead
Hibernate is an immensely powerful ORM layer with an array of features and mapping options which comes at the cost of complexity. The web application framework Grails ships with an ORM layer that builds of top of Hibernate, but eliminates much of the complexity through clever use of convention and the dynamic features of the Groovy language. Known as GORM, it offers a convention-based mapping strategy that hooks into the Hibernate configuration model and provides an abstraction layer above Hibernate with powerful features like Groovy builders for Criteria, dynamic finders and transaction management through closures.
Spring & Hibernate development, although hailed in the past as being "lightweight", is still an XML-centric, configuration heavy approach to web application development. In this talk, by Grails project lead Graeme Rocher, you will discover how you can leverage Spring & Hibernate without ever having to write a line of configuration!
Grails is more than just a web framework, it is a complete platform and API for runtime configuration. This talk, by Grails project lead Graeme Rocher, will demonstrate Grails' modular architecture and how to hook into runtime configuration to adapt your application based on its environment and/or the presence of other plug-ins.
Venkat Subramaniam - Founder of Agile Developer, Inc.
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 (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.
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.
What benefit do new Java 6 features offer you. Are there issues with using these features. The objective of this presentation is not simply to introduce you to the features, but to the effective use of these as well.
In this presentation we will introduce OSGi and discuss how it can help modularize and version your enterprise Java applications.
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.
Glenn Vanderburg - Chief Scientist, Relevance Inc.
Ajax applications have unique design and architectural challenges and opportunities. This presentation will show you how to take advantage of the Ajax's strengths, and work around its quirks.
The early years of computers -- the '50s and '60s -- were characterized by furious exploration of a huge variety of different ideas. Since then many of the hot topics of those days have moved to the fringe, largely ignored by the mainstream of software development. But some of them are being rediscovered, and a lot of what we think of as "new developments" are really just some old ideas returning to center stage.
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.
