GWT Best Practices

As the complexity of web applications continues to grow, the development tools provided to those creating such apps have remained, to a large extent, stagnant. The difficultly of adding the next “killer” feature while keeping load times reasonable and code size small can drive any Javascript guru to the brink of insanity. Google Web Toolkit provides tools that allow you to maintain your sanity and approach web development in the same manner you would any other large scale project. And much like any other set of tools, there are various ways to approach a project; some more efficient and scalable than others. The goal of “GWT Best Practices” is to take a deeper dive into slick ways to reduce code size, minimize RPC overhead, and streamline application development and testing using the MVP architecture within your GWT app.

The 90-Day Startup with Google AppEngine: A Case Study

Google AppEngine is a developer’s dream: one-button deployment, no servers to configure, and ultimate scalabilty. To get these benefits, however, you must learn to design within AppEngine’s constraints: no threads, no relational database, and a JRE whitelist, to name a few.
This presentation offers a peek inside a real-world GWT application deployed on AppEngine. We’ll look at working with the AppEngine database (including version upgrade considerations), how to do
background processing absent thread support, designing for quotas, and discuss one developer’s overall experience launching a startup on AppEngine.

Scala: Running on the JVM with Less Boilerplate

Java is ambitious in a few ways, but mostly it has been developed as one very practical decision after another. Scala rounds off the rough edges of Java by injecting it with many ideas from other languages, and it adds a few new features such as pattern matching that simplify your code further. I will describe the language and show a variety of ways it makes your code shorter and more to the point.

Google Wave for Developers

Google introduced Wave saying that this new online collaboration tool “reinvents email”. But they have offered developers a lot more than that. The Wave architecture incorporates many innovations since email - especially live cooperative editing. So Google challenges us to reinvent our communication apps with these possibilities in mind.

Wave is a big topic so the talk is organized in three parts with time for discussion:

  1. Wave - Product, Platform, and Protocol.
    An overview of Wave emphasizing the Wave platform for extension development.

  2. Wave architecture - Patterns for development.
    Approaches for using Wave’s live synchronization layer with new and existing web applications.

  3. Development of Wave robots in Java.
    The API for building Wave robots that watch user activity and respond with edits. Robot services range from simple text substitution to interfaces to existing web services.

Java EE 6 & GlassFish v3: Paving the Path for Future

The Java EE 6 platform is an extreme makeover from the previous versions. It is developed as JSR 316 under the Java Community Process.

The Java EE 6 platform adds more power to the platform and yet make it more flexible so that it can be adopted to different flavors of an application. It breaks the “one size fits all” approach with Profiles and improves on the Java EE 5 developer productivity features. It enables extensibility by embracing open source libraries and frameworks such that they are treated as first class citizens of the platform.

Several new specifications such as Java Server Faces 2.0, Servlet 3.0, Java Persistence API 2.0, and Context and Dependency Injection 1.0 are included in the platform. All these specifications are implemented in GlassFish v3 that provides a light-weight, modular, and extensible platform for your Web applications.

This session provides an overview of Java EE 6 and its Reference Implementation - GlassFish v3. Using multiple simple-to-understand samples it explains the value proposition provided by Java EE 6.

Hudson and Sonar - Automated Software Quality Control Tools

This session is aimed at helping developers get started with
automating the collection of software quality metrics. We’ll cover
continuous integration, automated code metrics gathering, and analysis
of these metrics. The ability to be able to detect problems early, and
also to write higher quality code early, helps avoid bugs and headache
down the line. We’ll cover some best practices around using and
putting in tools to help achieve higher quality.

This course centers around two freely available tools for maintaining
high quality codebases. The first is Hudson, a continuous integration
server. The second is Sonar, a code metrics server. In this session,
we’ll discuss best practices and then put them into use by setting up
and running these tools. We’ll also talk about tips for getting the
most out of these tools. If you aren’t using these tools in
development, you absolutely need to come to this session - it will
help make your life easier and impress your boss too!

9.7 Things Every Programmer Should Know About User Experience

The success of Web 2.0 and the popularity of mobile applications has revealed an important fact. Having an engaging or otherwise compelling user experience is critical to an application’s success. Given a choice, people will replace an application they find difficult to use with something that’s easier; even if the replacement doesn’t do everything the original did. Some businesses bring in professional User Experience Designers in an attempt to deal with this issue. The problem is that most designers don’t actually write code, and running code is the key factor in determining what kind of user experience your customers have.

That’s why it is critical that you understand the principles and fundamentals presented in this talk. You’ll leave with a better handle on what user experience is, and what you can do to ensure your application delivers the best possible user experience to your customers.

JSR-299 (CDI), Weld and the future of Seam

JSR-299: Contexts and Dependency Injection for Java EE is an elegant set of new services for Java that draws upon ideas from JBoss Seam and Google Guice. While many of the features provided (dependency injection, contextual lifecycle, configuration, interception, event notification) are familiar, the innovative use of meta-annotations is uniquely expressive and typesafe.

Seam is a powerful open source development platform for building rich Internet applications in Java. Seam is built on a JSR-299: Contexts and Dependency Injection for Java EE core (provided by Weld in JBoss Application Server), which integrates with Java EE technologies like JavaServer Faces (JSF) and Enterprise Java Beans (EJB 3.0). Seam integrates technologies such as Java Persistence (JPA), Business Process Management (BPM), Rules (Drools), Wicket, PDF and Excel reporting, Security and email into a unified full-stack solution, complete with sophisticated tooling.

HtmlUnit: An Efficient Approach to Testing Web Applications

Top-to-bottom integration testing is a critical step in delivering quality web applications. HtmlUnit is an open source headless browser for the JVM which provides an efficient means of automating these integration tests. Unlike most other tools in this area, HtmlUnit simulates a browser rather than driving a “real” browser, and is capable of emulating the behavior of Firefox or IE for a very large number of web applications: from simple old-fashioned pre-AJAX applications all the way to complex Web 2.0 apps.

HtmlUnit’s approach provides obvious benefits in areas such as ease of deployment, performance, scalability, and AJAX testing, but also has some limitations. Project committer Daniel Gredler will provide a detailed overview of the library, explain how to get the most out of the HtmlUnit approach, and show why in many cases it is far more efficient than working with a “real” browser to ensure the quality of your web app.

The intended audience of the session are Java (or other JVM language) developers who need to write top-to-bottom integration tests for their web applications.

Attendees will learn about:

  • The two approaches to web app integration testing: browser simulation vs browser driving
  • The cons of the browser simulation approach
  • The pros of the browser simulation approach
  • Key extension points provided by HtmlUnit
  • Wrappers which allow you to hedge your bets and switch between the two approaches

GWT MVP Case Study

The asynchronous nature of GWT development requires a new way of thinking, especially for long-time server-side Web developers. How to notify views of changes to the model? Communicate between views? Cache data from service calls? And how to avoid UI spaghetti code? In this talk, you’ll get a close-up look at a real-world app using the Model View Presenter pattern as implemented by the gwt-presenter and gwt-dispatch frameworks. We’ll cover the event bus, decoupling presenters and views, making secure service calls with the Command pattern, and how GWT+MVP supports caching and an Undo feature. Learn what MVP is all about and whether it’s right for you.

Smithing in the 21st Century

Blacksmiths in 1900 and PowerBuilder developers in 1996 have something in common: they thought their job was safe forever. Yet circumstances proved them wrong. One of the nagging concerns for developers is how do you predict the Next Big Thing, preferably before you find yourself dinosaurized. This keynote discusses why people are bad at predicting the future, and why picking the Next Big Thing is hard. Then, it foolishly does just that: tries to predict the future. I also provide some guidelines on how to polish your crystal ball, giving you tools to help ferret out upcoming trends. Don’t get caught by the rising tide of the next major coolness: nothing’s sadder than an unemployed farrier watching cars drive by.

Domain-Driven Design: An Introduction

The first book on Domain-Driven Design was published in 2003, authored by Eric Evans, who first coined the term and distilled the time-tested principles and patterns that make up the practice of DDD. In recent years, simplification and increased testability through frameworks like Spring, Hibernate, and others has substantially reduced the complexity of application infrastructure, allowing teams to turn their focus to honing their approach to software design. Domain-Driven Design meets practitioners in that quest with principles, practices, and process to recapture the spirit of software excellence that has been lost in so many of today’s technology practices.

This talk will introduce the foundations of Domain-Driven Design, and present several facets of DDD in action:

  • How models are chosen and evaluated
  • How multiple models coexist
  • How patterns help to avoid common pitfalls, such as overly-interconnected models
  • How developers and domain experts together in a DDD team engage in deeper exploration of their problem domain and make that understanding tangible as a practical software design

From whiteboard to product launch

There are numerous resources available that cover the topic of software development process and project management. There are numerous resources available that cover tools, frameworks, libraries, containers, application servers, languages, databases and so on. There are numerous resources available that cover software architecture. There are numerous resources that cover software quality assurance and testing. There are numerous resources that cover team structure, organization and work environment.

The truth is, all of these topics have an impact on whether we are ultimately successful in getting the job done. This talk aims to touch all of these topics by providing an honest retrospective into how we developed and bought a brand new product to market.

We will cover the trade-offs, the challenges, the mistakes, the process, the tools, the frameworks, the regrets, the work environment and the team organization. You will learn that there are many choices to be made during the course of a software development project. You will learn about the choices we made – and you will learn that just because the choices worked for us doesn’t necessarily mean they will work for you. The goal is for you to find this useful material – whether you are building a corporate IT system, or if you are building a new software product or service regardless of whether you are developer, a product manager, an architect, a test engineer or a project manager.

User Stories: Agile and Lean Requirements

A large number of Agile adoption initiatives start at a grassroots level among software developers who have grown uncomfortable with the blatant inefficiencies of classic approaches to software development. The teams who succeed often find themselves working more efficiently, but the impact of their success is hindered. They are still relegated to taking large functional specifications and digesting them into iterations of work, with little if any feedback from the business side of the house. A series of successful sprints can still be met with the cliche “that’s not what we wanted” response, leaving development teams relegated to the “well that’s what you wrote” response. Until the business people are participating in iterative feedback and realizing the flexibility and freedom they have in working with these Agile teams, there will always be a ceiling on their success.

Attendees of this talk will be guided through pragmatic, proven approaches for building that bridge to the business representatives. A thorough treatment of how user stories can be used as an effective tool that allows business and development sides of the house to meet in the middle, as well as when and how to bend in order to move the adoption process forward. It will also cover the sometimes subtle pitfalls and hotspots of promoting a fully Agile process with participating business team members, and ways to hopefully allow good deeds to continue to go unpunished.
