  • Polymer and Elements

    Taylor Savage / Google

    Room 1

    11:00–11:50 am

    The Web Components standards create a brand new set of primitives that makes it immensely easier to develop for the web. The Polymer library ties these primitives together to provide an opinionated way to declaratively create robust, encapsulated components that can be easily dropped into web apps. We'll walk through the sugaring that Polymer provides on top of Web Components, highlight different types of elements that the Polymer team and community is creating with the library, and show how complex web apps can be assembled from simple, interoperable Polymer elements.

  • Inside the compiler

    Roberto Lublinerman / Google

    Room 2

    10:00–10:50 am

    In this talk will explore the GWT compiler internals. We'll look at its overall architecture, the internal representations during the compilation process and explore in detail the different passes. This presentation will give you the insight needed to understand the compiler, contribute fixes and enable you to create new compiler passes.

  • Incremental compilation

    John Stalcup / Google

    Room 2

    11:00–11:50 am

    Imagine a fully functional touch based user interface for remote controlling a small drone or a helicopter. This is doable with latest experimental integrations around drone controlling backend applications over WIFI with touch based control interface built with GWT or Vaadin. During the session such a system will be presented with full technology stack starting from GWT based frontend to the actual backend controller application.

    A live drone will also be flown during the presentation maintaining a safe distance from the audience.

  • Comparing GWT Transport Mechanisms

    Leif Åstrand / Vaadin

    Room 2

    3:30–4:20 pm

    There are lots of options for transporting data to and from your GWT app running in the browser. Solutions like GWT RPC, RequestFactory and Protocol Buffers promise to do the heavy lifting for you. Or then you might want to roll your own based on RequestBuilder or similar low level APIs. To further complicate things, frameworks like Errai and Vaadin also provide their own communication mechanisms. Which one should you use? What are the pros and cons? Let’s find out!

  • Automated testing of web apps

    Jonatan Kronqvist / Vaadin

    Room 2

    4:30–5:20 pm

    Testing is an important part of all software projects – and so is keeping sane. In order to not make the developers and testers lose their minds while verifying that a huge amount of features still work, the testing should be automated. What’s worse, the complexity of the underlying technologies often make it more challenging to test web applications than conventional software.

    This talk will show you some tools and methodologies for automated testing of web apps and especially the user interface layer of web apps. It will discuss how to architect a web app for easy testing and what kind of tests should go where and in which situation. We’ll even have a look at how the customer requirements can be automatically tested and verified to work – exactly as specified by the ones paying the bills.

  • J2ObjC: Sharing Java Code with iOS Applications

    Tom Ball / Google

    Room 2

    5:30–6:20 pm

    J2ObjC is an open-source Java to Objective-C transpiler for iOS apps, which is used by apps like Google's Inbox to share code between their GWT, Android, and iOS implementations. This talk provides a deep dive into J2ObjC: how it is designed, what differences there are between shared code on different platforms, and some best practices for minimizing code rewriting. A quick review of a sample Xcode project will demonstrate how Java sources can be included in iOS apps.

  • Best development practices for GWT web applications

    Julien Dramaix / Arcbees

    Room 3

    3:30–4:20 pm

    GWT is a powerful framework for developing complex web applications. However developing large applications with multiple developers can quickly become problematic. How to keep some structure in the code ? Pass information through developers ? Or keep a high level of quality code? In this presentation, we will talk about several good practices, tools and libraries and the processes we use at ArcBees to develop quickly large quality GWT applications.

  • Functional and reactive UI programming

    Henri Muurimaa / Vaadin

    Room 3

    4:30–5:20 pm

    The functional reactive programming style approaches application logic by turning data flows into composable entities called observables. This is useful in the backend, but it can be leveraged in the front end, too. If we consider UI events from user as value streams we can express all of our UI logic as combinations of observables. Join this presentation to find out a new way of building user interfaces.

  • Improving the HTML table: a quick guide on getting in over your head

    Leif Åstrand / Vaadin

    Room 3

    5:30–6:20 pm

    Smooth continuous scrolling through millions of concurrently edited rows on an old iPad. Sounds easy, right? To achieve 60fps, you need to find the right data, insert it into the DOM and get the browser to layout and render in less than 16 ms. And then there’s also this detail about how overflow: auto works with tens of millions of pixels...

    This presentation will look at all the low-level challenges we faced when pushing the limits of browsers for the new Grid widget for GWT and Vaadin.

  • Demo Stage

    Session host: Colin Alworth / Sencha

  • Introduction to Vaadin

    Henri Muurimaa / Vaadin

    Room 1

    10:00–10:50 am

    Vaadin is a popular web framework that makes it possible to write rich user interfaces in server-side Java. Writing an application that lazily loads large amounts of data from the server, includes drag-and-drop, keyboard navigation and compelling visualizations would not require writing any HTML, JavaScript or resigning a REST API. While the server centric development model provides the best productivity, Vaadin also supports client-side development though the GWT based Java to JavaScript compiler as well as JavaScript. The default looks of the application can be customized with CSS and Sass.

    The presentation gives an overview to Vaadin and explain how it works. We'll also discuss on what are the differences and the relationship between Vaadin and GWT. The session should give you everything you need to get started building your own apps with the free Apache-licensed Vaadin.

  • Singular - Reimagining AngularJS in Java

    Daniel Kurka / Google

    Room 1

    11:00–11:50 am

  • Easy cross-platform RPC with Jersey and resty-gwt

    David Chandler / Sencha

    Room 2

    11:00–11:50 am

    Creating a service layer with GWT has changed significantly from the initial GWT-RPC to frameworks based on the Command pattern such as gwt-dispatch and the RequestFactory. In this presentation, we'll talk about the pros and cons of various approaches and show how the open source resty-gwt framework combines the simplicity of GWT-RPC service interfaces with the power of the command pattern for caching and XSRF protection. You'll learn how easy it is to create a REST+JSON API on the server using Jersey, App Engine, and Objectify 5 and how to create a generic CRUD API on both client and server. Finally, you'll learn how to implement an authentication filter on the server and authentication callbacks in the GWT client using Jersey and resty-gwt. As a bonus, the presentation will be based on an open source sample project with a working Maven pom for all of the above.

  • Speed up your GWT coding with gQuery

    Manuel Carrasco Moñino / Vaadin

    Room 3

  • Rapidly Build Cloud IDEs with UberFire

    Alexandre Porcelli / Red Hat

    Room 1

    2:00–2:50 pm

    Learn how to build rich cloud-based IDEs using UberFire. UberFire is a web framework for a superior experience in building extensible workbenches and console type applications. Cloud-based IDEs are a big trend now, so it seemed like a perfect match.

    In this session Alexandre and Michael will explore, in a polyglot fashion, all UberFire features that are key for Cloud IDEs, such as:

    • The Virtual File System API that uses git as its default backend;
    • Multiple perspective definitions providing mechanisms for task-oriented interaction with resources, multi-tasking and information filtering;
    • A flexible windows system where developers can use different layout managers;
    • Plugin-based editors that can be developed using GWT, ErraiUI, AngularJS or your preferred language or framework.

    By using UberFire to build such a tool you also get for free an HA enabled environment plus:

    • A metadata with search capabilities that will automatically index all your git repositories;
    • An unified security framework;
    • A lightweight Maven repository manager.

    Attendees will see an overview of challenges faced when building a Cloud IDE, how Uberfire approaches these challenges, lessons learned in a real world use case (obtained by building Red Hat JBoss BRMS and BPMS platforms) and mostly important: a cool live demo.

  • Cell Widgets in the Wild

    Chris DiGiano / Google

    Room 2

    1:00–1:50 pm

    Cell widgets offer the promise of fast, highly-scalable tables, lists, and trees in GWT, but they also don’t fit neatly into common UI design patterns. In this talk I’ll describe some of the challenges one encounters when going beyond the example code to apply cell widgets in complex, real-world systems like Google Groups. I’ll present techniques that developers at Google have used to manage the complexities of using cell widgets for event handling and rendering of non-trivial DOM structures.

  • Tessell: A functional* reactive framework for GWT

    Stephen Haberman / Bizo

    Room 2

    2:00–2:50 pm

    While few would call Java or GWT "functional", the main idea of reactive programming can be applied to GWT applications to radically simplify large applications with complex behaviors. Tessell is a framework that provides a reactive core and a sophisticated DSL for binding smart models with GWT widgets.

  • Java EE with Vaadin

    Peter Lehto / Vaadin

    Room 3

    1:00–1:50 pm

During this session we will look in detail on how multi-view Vaadin applications are built and coupled with Java EE based business systems using Context and Dependency Injection (CDI). Important topics covered within the session are the best practices of Vaadin enterprise integration design, Vaadin-CDI addon for providing smooth connectability to the backend as well as known best practices which Vaadin teams uses in their daily work.

  • Visual designer

    Marc Englund / Vaadin

    Room 3

    2:00–2:50 pm

    Whether UI should be built programmatically, declaratively or with a visual tool is always a good flamewar starter. In this session we discuss benefits of each approach and design Vaadin team took when redesigning our visual design tool from scratch. While the tool today is limited to Vaadin based UI, we will discuss possiblities of expanding the use to GWT and Web Components in general.

  • Workshop: Contributing to GWT

    Manuel Carrasco Moñino / Vaadin
    Julien Dramaix / Arcbees

    Room 4

    1:00-2:50 pm

    This presentation will show what we have been cooking in Vaadin Labs with Web Components. Lets not spoil the surprise in here. Expect something interesting ;)

  • Rich HTML5 Web Apps: Introduction to Errai 3

    Christian Sadilek / Red Hat

    Room 2

    3:30–4:20 pm

    Building small web sites with some basic functionality is easy using any of the modern JavaScript frameworks but implementing a maintainable large-scale web application is a tough job. GWT has a track record of being a stable and robust programming toolkit that is perfectly suited for building large web applications. Errai enables your team to share Java EE (JPA, JAX-RS, CDI) code between the client and the server and reuse functionality across application layers. In this session, you will learn how to build rich web applications the toolable, typesafe way, without boilerplate using Errai's concise programming model. Next-generation web applications can now be built by combining the best aspects of JavaScript, Java and HTML5 using Errai.

  • Building HTML5 Animation Editor in GWT

    Dmitry Skavish / Animatron

    Room 3

    Smooth continuous scrolling through millions of concurrently edited rows on an old iPad. Sounds easy, right? To achieve 60fps, you need to find the right data, insert it into the DOM and get the browser to layout and render in less than 16 ms. And then there’s also this detail about how overflow: auto works with tens of millions of pixels...

    This presentation will look at all the low-level challenges we faced when pushing the limits of browsers for the new Grid widget for GWT and Vaadin.

  • Best development practices for GWT web applications

    Julien Dramaix / Arcbees

    Room 3

    3:30–4:20 pm

    GWT is a powerful framework for developing complex web applications. However developing large applications with multiple developers can quickly become problematic. How to keep some structure in the code ? Pass information through developers ? Or keep a high level of quality code? In this presentation, we will talk about several good practices, tools and libraries and the processes we use at ArcBees to develop quickly large quality GWT applications.

  • Functional and reactive UI programming

    Henri Muurimaa / Vaadin

    Room 3

    4:30–5:20 pm

    The functional reactive programming style approaches application logic by turning data flows into composable entities called observables. This is useful in the backend, but it can be leveraged in the front end, too. If we consider UI events from user as value streams we can express all of our UI logic as combinations of observables. Join this presentation to find out a new way of building user interfaces.

  • Remote controlling a drone with Spring & Vaadin

    Peter Lehto / Vaadin
    Fredrik Rönnlund / Vaadin

    Room 3

    5:30–6:20 pm

    Wouldn't it be crazy to fly a small drone or helicopter with your phone or tablet running nothing but a web browser? This session will tell you all about it!

    Imagine a fully functional touch based user interface for remote controlling a small drone or a helicopter. This is doable with latest experimental integrations around drone controlling backend applications over WIFI with touch based control interface built with GWT or Vaadin. During the session such a system will be presented with full technology stack starting from GWT based frontend to the actual backend controller application.

    A live drone will also be flown during the presentation maintaining a safe distance from the audience.

  • Introduction to Vaadin

    Henri Muurimaa / Vaadin

    Room 1

    10:00–10:50 am

    Vaadin is a popular web framework that makes it possible to write rich user interfaces in server-side Java. Writing an application that lazily loads large amounts of data from the server, includes drag-and-drop, keyboard navigation and compelling visualizations would not require writing any HTML, JavaScript or resigning a REST API. While the server centric development model provides the best productivity, Vaadin also supports client-side development though the GWT based Java to JavaScript compiler as well as JavaScript. The default looks of the application can be customized with CSS and Sass.

    The presentation gives an overview to Vaadin and explain how it works. We'll also discuss on what are the differences and the relationship between Vaadin and GWT. The session should give you everything you need to get started building your own apps with the free Apache-licensed Vaadin.

    Anton Kosyakov / Itemis

    Room 2

    11:00–11:50 am

    Xtend is a modern programming language that is 100% compatibly with existing Java libraries and even translates to readable Java source code. With it's slick syntax and powerful features such as lambdas, operator overloading and compile-time macros you can turn any verbose piece of Java code into a small and elegant piece of expressive Xtend code.

    In this session we will show how Xtend can be used to program GWT applications and how well the typical GWT idioms are supported by the language.

  • DIY: Computer Vision with GWT

    Alberto Mancini / Jooink
    Francesca Tosi / Jooink

    Room 3

    10:00–10:50 am

    The talk focuses on how to use GWT to mix some of our beloved plain old java libraries (BoofCV and NyARtoolkit for instance) with WebRTC and WebGL to make realtime computer vision and augmented reality: right in the browser, plugin free and … even mobile with mGWT.

    We will show how much GWT, jointly with some of the the new HTML5’s API, enables browser based “compute intensive” applications.

  • Speed up your GWT coding with gQuery

    Manuel Carrasco Moñino / Vaadin

    Room 3

    11:00–11:50 am

    GwtQuery is a rewrite of the jQuery popular library with has brought to the GWT world its sexy API and its simplicity for doing complex things.

  • Rapidly Build Cloud IDEs with UberFire

    Michael Anstis / Red Hat
    Mauricio Salatino / Red Hat

    Room 1

    2:00–2:50 pm

    Learn how to build rich cloud-based IDEs using UberFire. UberFire is a web framework for a superior experience in building extensible workbenches and console type applications. Cloud-based IDEs are a big trend now, so it seemed like a perfect match.

    In this session Alexandre and Michael will explore, in a polyglot fashion, all UberFire features that are key for Cloud IDEs, such as:

    • The Virtual File System API that uses git as its default backend;
    • Multiple perspective definitions providing mechanisms for task-oriented interaction with resources, multi-tasking and information filtering;
    • A flexible windows system where developers can use different layout managers;
    • Plugin-based editors that can be developed using GWT, ErraiUI, AngularJS or your preferred language or framework.

    By using UberFire to build such a tool you also get for free an HA enabled environment plus:

    • A metadata with search capabilities that will automatically index all your git repositories;
    • An unified security framework;
    • A lightweight Maven repository manager.

    Attendees will see an overview of challenges faced when building a Cloud IDE, how Uberfire approaches these challenges, lessons learned in a real world use case (obtained by building Red Hat JBoss BRMS and BPMS platforms) and mostly important: a cool live demo.

  • Cell Widgets in the Wild

    Chris DiGiano / Google

    Room 2

    1:00–1:50 pm

    Cell widgets offer the promise of fast, highly-scalable tables, lists, and trees in GWT, but they also don’t fit neatly into common UI design patterns. In this talk I’ll describe some of the challenges one encounters when going beyond the example code to apply cell widgets in complex, real-world systems like Google Groups. I’ll present techniques that developers at Google have used to manage the complexities of using cell widgets for event handling and rendering of non-trivial DOM structures.

  • Easy cross-platform RPC with Jersey and resty-gwt

    David Chandler / Sencha

    Room 2

    2:00–2:50 pm

    Creating a service layer with GWT has changed significantly from the initial GWT-RPC to frameworks based on the Command pattern such as gwt-dispatch and the RequestFactory. In this presentation, we'll talk about the pros and cons of various approaches and show how the open source resty-gwt framework combines the simplicity of GWT-RPC service interfaces with the power of the command pattern for caching and XSRF protection. You'll learn how easy it is to create a REST+JSON API on the server using Jersey, App Engine, and Objectify 5 and how to create a generic CRUD API on both client and server. Finally, you'll learn how to implement an authentication filter on the server and authentication callbacks in the GWT client using Jersey and resty-gwt. As a bonus, the presentation will be based on an open source sample project with a working Maven pom for all of the above.

  • Java EE with Vaadin

    Peter Lehto / Vaadin

    Room 3

    1:00–1:50 pm

    Vaadin is Java framework for rapid development of highly interactive HTML5-based web applications. Because of server-driven nature Vaadin can easily be integrated with server-side Java EE features such as EJBs and JPA. During this session we will look in detail on how multi-view Vaadin applications are built and coupled with Java EE based business systems using Context and Dependency Injection (CDI). Important topics covered within the session are the best practices of Vaadin enterprise integration design, Vaadin-CDI addon for providing smooth connectability to the backend as well as known best practices which Vaadin teams uses in their daily work.

  • Visual designer

    Marc Englund / Vaadin

    Room 3

    2:00–2:50 pm

    Whether UI should be built programmatically, declaratively or with a visual tool is always a good flamewar starter. In this session we discuss benefits of each approach and design Vaadin team took when redesigning our visual design tool from scratch. While the tool today is limited to Vaadin based UI, we will discuss possiblities of expanding the use to GWT and Web Components in general.

  • Workshop: Contributing to GWT

    Manuel Carrasco Moñino / Vaadin
    Julien Dramaix / Arcbees

    Room 4

    This presentation will show what we have been cooking in Vaadin Labs with Web Components. Lets not spoil the surprise in here. Expect something interesting ;)

  • Rich HTML5 Web Apps: Introduction to Errai 3

    Christian Sadilek / Red Hat

    Room 2

    3:30–4:20 pm

    Building small web sites with some basic functionality is easy using any of the modern JavaScript frameworks but implementing a maintainable large-scale web application is a tough job. GWT has a track record of being a stable and robust programming toolkit that is perfectly suited for building large web applications. Errai enables your team to share Java EE (JPA, JAX-RS, CDI) code between the client and the server and reuse functionality across application layers. In this session, you will learn how to build rich web applications the toolable, typesafe way, without boilerplate using Errai's concise programming model. Next-generation web applications can now be built by combining the best aspects of JavaScript, Java and HTML5 using Errai.
