Java

The Internet Of Things (IoT) brings the whole new challenges to the world of the messaging solutions. Gathering data from the field and delivering it to the cloud is a common task for IoT solutions. Developers find themselves struggling with field protocols on one side and data delivery protocols on the other. Eclipse Kura is a well-recognized field gateway for IoT applications. Apache Camel is a message-routing engine and a library containing a gazillion various endpoint connectors. And last, but not least, Rhiot project attempts to make the Kura and Camel developer experience even better. In this session, you'll learn how Red Hat combines Kura, Camel, and Rhiot to create rocking IoT gateway solutions.

Join us in March 21-23 for Devoxx US 2017, details @ https://devoxx.us The main consequence of the introduction of lambda expressions in Java 8 is the possibility of conveniently mixing the object oriented and the functional paradigms. Nevertheless the biggest part of Java developers is not used yet to employ functional idioms and then they are not ready to fully leverage the new functional capabilities of Java. In particular it is still uncommon to see functions used together with data in business domain model. The purpose of this talk is not doing a comparison between object oriented and functional programming, but showing how these two styles can be combined in order to take advantage of the good parts of both. For example it's usual to pass a list of data to a function that processes them, but there are cases when you may want to create a list of functions and pass a single data through all of them. Immutable objects leads to a inherently thread-safe domain model. Functions often compose better than objects. Side-effect free code allows better reusability. This talk will demonstrate the validity of these statements with practical examples till to distil the essence of functional programming: data and behaviours are two aspects of the same thing.

Join us in March 21-23 for Devoxx US 2017, details @ https://devoxx.us Vert.x 3 is a toolkit to create reactive applications on the Java Virtual Machine. Vert.x 3 takes the JVM to new levels of reactive awesomeness: it lets you build scalable applications transparently distributed in Java, JavaScript, Ruby and Groovy. And, you don’t have to choose a single language, but mix them! This talk presents the key concepts of Vert.x and how you can use it to build your next application. This session explains how the simple model promoted by Vert.x enables the construction of concurrent, scalable and efficient micro-service based applications. Several examples are developed during the talk and demonstrates Vert.x features such as the distributed event bus, the high availability, the polyglot aspect and vert.x web.

The work on JSR 365 (Context and Dependency Injection for Java) started one year ago. Expert group already added interesting features like asynchronous events or Java SE bootstrap. Thanks to early draft and alpha version of CDI 2.0 implementation we can already experiment the future CDI 2.0. In this talk we will show the top new features in CDI 2.0 thru code examples (when possible) and presents expert group serious leads for the end of this first totally open source Java EE specification.

Even the simplest application ideas always end up requiring more development than you hoped for: maintaining long-lived state, interaction with other services or human actors performing some of the work, showing current status of ongoing requests, management and reporting, etc. Business processes and rules allow you to externalize some of that logic and dynamically update it, but you don't want your business process management (BPM) system to get in your way either. And every application is different, so you want to be able to fully control every bit of it. Using process-driven application development, you define your application logic in a (flexible) business process, but you also expect your BPM system to help you out with much more than that. In this session we will show you live how to quickly get new web applications up and running by relying on jBPM to provide some of the UI (should you want to), or even to generate parts of your application for you (that you can customize later), so you can focus on what makes your application different. jBPM uses the power of open source and it's flexible architecture to let you decide what you need: nothing more, nothing less.

This session presents how you can develop a realtime web application with vert.x web. In this context, a small game is going to be developed on stage demonstrating how easy it is to build such kind of applications with Vert.x 3. Of course attendees can play the game.

Docker is awesome, but how to use it well when doing Java development ? In this talk you will get a quick introduction on how to use Docker effectively, especially for Java EE development. We will show how the recent release of Eclipse Mars supports Docker to make it even more integrated into your day-to-day work from within your IDE. In particular, you'll see how you can pull and run an image for a database, build a custom image for an application server, run it and deploy a JavaEE application using data volume, exposed ports and container links. And more !

Fabric8 is an integration and management platform adding to the Java developer's perspective of Kubernetes and OpenShift. It consists of multiple parts. Fabric8 tooling helps tremendously in deploying Java applications on Kubernetes and OpenShift by creating all the complex deployment descriptors directly from a Java build. In addition, fabric8 contains a rich set of DevOps Microservices which provides a flexible and automatedsetup for a Continous Integration and Delivery pipeline on a per project basis. It also includes an integration-Platform-as-a-Service (iPaaS) centered around Camel and ActiveMQ with rich visualisations and one click installations. But the queen of fabric8 is its web console which allows for a rich user experience for managing Kubernetes services, pods and more. With this in place even complex setups can be easily managed. This talk provides an overview over all these components and shows how the pieces fit together.

You have a great idea for quick and interesting mapping application with pins on a map with some basic search. Then you lose interest because of all the pieces to install. NOT ANYMORE! In this workshop we are going to use 1 command to spin up all our infrastructure (EAP and MongoDB). Then write some quick and easy Java EE code to build a REST service on MongoDB. To wrap it up we will use a simple Leaflet application to display the results. You will witness the transformation from idea to cool pinny map in this quick session.
