Speaker: Bob McWhirter
Feb, 09 2016
WildFly Swarm makes it possible to wade into the great ocean of microservices without abandoning your JavaEE knowledge and experience. In this talk, we’ll introduce you to what makes WildFly Swarm similar to and distinct from proper WildFly. We will explore how WildFly Swarm can enable a microservices architecture. We’ll also demonstrate how to weave together multiple services to have a non-trivial application composed of multiple, independently-deployable services.
For this session we have Bob McWhirter talking about WildFly Swarm, which is a project he founded to bring microservices to the Java EE world.
An Enterprise Developer’s Journey to the IoT
Speaker: Burr Sutter
Dec, 17 2015
The current hype around the Internet of Things (IoT) has led to a substantial amount of innovation thanks to open source software, open hardware, open standards, and community inspiration.
In this session, we will explore how you can use open source software to incorporate the physical world (the “Things”) into your traditional enterprise IT infrastructure. We will walk the path from a typical enterprise developer’s current focus on web desktop applications to mobile and devices, specifically developer prototyping platforms like Raspberry Pi, Intel Edison, Arduino, Particle.io, and several others.
Learn how to connect the physical world to your enterprise middleware backbone via sensors and actuators.Demo Links:

Speaker: Martyn Taylor
Nov, 10 2015
Scale changes everything. What once was quite adequate for enterprise messaging can't scale to support "Internet of Things". We need new protocols, patterns and architectures to support this new world. This session will start with basic introduction to the concept of Internet of Things. Next it will discuss general technical challenges involved with the concept and explain why it is becoming mainstream now. Now we’re ready to start talking about solutions. We will introduce some messaging patterns (like telemetry and command/control) and protocols (such as MQTT and AMQP) used in these scenarios. Finally we will see how Apache ActiveMQ is gearing up for this race. We will show tips for horizontal and vertical scaling of the broker, related projects that can help with deployments and what the future development road map looks like.
Martyn Taylor is a senior software engineer at Red Hat, with over 7 years’ experience working on cloud, middleware and messaging software. Martyn currently works on the Apache ActiveMQ suite of projects.
JGroups - An effective framework for cluster communication
Oct 6, 2015

The cold hard truth about microservices and how open source can help
Speaker: Christian Posta - Principal Middleware Specialist
Sep 8, 2015
Microservice architectures have become popular, but we have to balance hype with reality. Microservices make it harder to manage deployments and create complex inter-service communications patterns. Learn how Open Source software built by open communities like Apache Camel, Docker, Kubernetes, OpenShift and Fabric8 can help achieve organizational goals to integrate services and establish effective continuous integration and continuous delivery pipelines.
Apache Lucene for Java EE developers
Jul 14, 2015
Apache Lucene is the de-facto standard open source library for Java developers to implement full-text-search capabilities.
While it’s thriving in its field, it is rarely mentioned in the scope of Java EE development.
In this talk we will see for which features many developers love Lucene, make some concrete examples of common problems it elegantly solves, and see some best practices about using it in a Java EE stack.
Finally we’ll see how some popular OSS projects such as Hibernate ORM (JPA provider), WildFly (Java EE runtime) and Infinispan (in-memory datagrid, JCache implementor) actually provide great Lucene integration capabilities.What's New in WildFly 9
Jun 16, 2015
This session covers new improvements that will be introduced in WildFly 9:
- Wildfly-core will be extracted from the codebase and the ability to assemble a server on top of it will be introduced. WildFly 9 will be provided in two versions: Wildfly Web and Wildfly Full but users will be able to create their custom packaging of WildFly.
- Users will be able to shutdown the application server in a graceful manner - after the shutdown command is executed server will reject new requests and allow existing requests to finish before it shuts down.
- Support for HTTP/2, a new version of HTTP protocol based on SPDY, will be introduced.
- Users will be able to use WildFly as a load balancer. Consequently, it will be possible to manage the balancer with the same tools that are used to manage the rest of the domain. What is more, users will be able to use more efficient protocols, such as HTTP/2, for communication between the balancer and backend servers.
An OpenShift cartdridge, which will enable users to use WildFly 9 in cloud environment, will be provided.
WildFly 9 will use OpenJDK ORB library instead of JacORB.Narayana 5: The premier open source transaction manager

Building Cross Platform Applications with Cordova and AeroGear
Apr 20, 2015
Mobile devices are increasingly important as a platform. The number of different devices on the market increases every day. This posses a challenge, how do we support all of them. Every new device comes with it's own paradigms and programming language. Wouldn't it be great if we could create one application that could support all platforms. With Cordova and AeroGear you can.
Cordova is a platform that allows you to access native device functions from JavaScript enabling you to create mobile applications with just CSS, HTML and JavaScript, for all platforms. You can use your existing skill sets to create native applications.
In this talk we'll show how you can create an application with Cordova and even how to create your own plugins. What features the AeroGear Plugins have and how you can use these to build mobile applications rapidly. How to create test and run these on simulators and integrate them into your own build environment.Implementing your own Google App Engine
Mar 10, 2015
Google App Engine (GAE) is a popular PaaS offering. Where its scalable and reliable environment is hidden behind a custom API. This makes GAE apps hard to port over to other non-GAE environments.
But what if one could implement such similar environment? And you could simply move your GAE application’s .war file to this new environment and it would just work?
After all, at the end it’s all about the API, plus scalable and reliable services.
JBoss CapeDwarf project aims at making this a reality. This presentation will provide a glimpse into what it takes to implement something as GAE, ranging from runtime integration with JBoss Application Server, actual services implementation to last but not least, automated heavy testing.Hit the ground running with BPM — a starters kit

Speaker: Antoine Sabot-Durand
Jan 20, 2015
CDI portable extensions are one of greatest features of Java EE allowing the platform to be extended in a clean and portable way. But allowing extension is just part of the story. CDI opens the door to a whole new eco-system for Java EE, but it’s not the role of the specification to create these extensions.
Apache DeltaSpike is the project that leads this brand new eco-system by providing useful extension modules for CDI applications as well as tools to ease the creation of new ones.
In this session, we’ll start by presenting the DeltaSpike toolbox and show how it helps you to develop for CDI. Then we’ll describe the major extensions included in Deltaspike, including 'configuration', 'scheduling' and 'data'.Antoine Sabot-Durand is the CDI co-spec lead. He is also the tech lead of the Agorava project.
CDI (Part 2): The Advanced Features
Speaker: Antoine Sabot-Durand
Dec 8, 2014
This presentation introduces the advanced features of CDI (Contexts and Dependency Injection). It was presented by Antoine Sabot-Durand, the co-spec lead for CDI.
In less than five years of existence, Contexts and Dependency Injection (CDI) has become one of the major specifications in Java EE. However, its advanced features are still not well known among the majority of the developers, who see it as a simple Dependency Injection solution. In this session, we’ll deep dive into advanced features like the CDI SPI and portable extensions. Then we'll view some examples of how CDI can be used to extend, in a portable way, the Java EE stack.CDI (Part 1): Introduction to CDI

Testing the Enterprise layers, with Arquillian
Speaker: Aslak Knutsen
Oct 21, 2014
Arquillian is an innovative and highly extensible testing platform for the JVM that enables developers to easily create automated integration, functional and acceptance tests for Java middleware, from Java EE and beyond.
For years we've been exploring how to layer and separate our code to test in isolation on the unit level. We've kept integration and functional testing as a big ball of mud; jumping straight from unit to full system testing. But can we apply some of the same lessons learned from unit to integration testing?Arquillian project lead, Aslak Knutsen, is a Senior Software Engineer at Red Hat where he is working on projects such as Arquillian and ShrinkWrap, one of the founders of the JBoss Testing initiative and a speaker at major industry conferences including JavaOne, Devoxx, Jazoon, JFokus, Geecon, JUDCon and JBoss World.

Transactions in the Cloud
Aug 12, 2014
For this meetup we have two short talks, both with a 'Transactions in the Cloud' theme. The talks cover some novel research undertaken by this summer's intern students.
Transactions and NoSQL Review
It is a common to forgo the use of transactions in an application due to untested performance or scalability concerns. While it is true that transactions do come at a cost, they also bring a lot of strong guarantees essential to a correctly running application. There are many differing transaction options available, each with varying costs and guarantees. Rather than dismiss transactions altogether, it would be more prudent to consider how your application would perform under a number of different transaction models and select the option that hits the right balance of performance and guarantees.
This presentation provides a useful reference for developers and architects who need the guarantees that transactions can bring, but don't know which model is right for them. In particular the presentation will:- Review each of the transaction options available in NoSQL today.
- Compare ACID and Extended (relaxed ACID) transaction models and understand how these models relate to NoSQL and scalability.
- Present performance results for a selection of transaction options under different classes of workload. Covering a single node, as well as cluster of sharded nodes.
Transaction coordination systems such as Narayana rely upon storage facilities to recreate transaction state during recovery from a system crash. These logs are usually stored on RAID hard drives to maximize reliability. However, any disk I/O is relatively slow and writing the logs can become a bottleneck in high performance transaction systems. Using the fastest available disk subsystems is thus an expensive necessity for many enterprise applications.
The use of a cluster of inexpensive, unreliable hardware nodes in conjunction with data replication for redundancy is an increasingly popular and cost effective architecture for many highly scalable, high reliability applications. Data grids such as Infinispan provides distributed in-memory replication of Java objects, making programming for this kind of cluster relatively simple.
This presentation will cover a new transaction logging plugin for Narayana that uses a data grid to replicate the logs to main memory on other nodes in a cluster, in preference to writing them to disk. In addition, the presentation will also cover performance benchmarks and reliability trade-offs.What's new in WildFly 8?
Jul 8, 2014
For this session we have the WildFly project lead, Jason Greene.
WildFly 8 (née JBoss Application Server) is Red Hat's open source Java EE 7 compliant application server. It contains robust implementations of WebSocket, Batch, JSON, Concurrency, JMS2, JAX-RS 2, CDI 1.1, and all Java EE 7 technologies. Undertow is the new cutting-edge web server in WildFly 8 and is designed for maximum throughput and scalability, including environments with over a million connections. The number of ports is reduced used by multiplexing protocols over HTTP using HTTP Upgrade.
Role Based Access Control support organizations with separated management responsibilities and restrictions. Roles represent different sets of permissions such as runtime operation execution, configuration areas that can read or written, and the ability to audit changes and manage users. In addition a new restricted audit log can be enabled including the ability to offload to a secure syslog server.
WildFly also provides a 'core' distribution that is ideal for framework authors that want to build their own application runtime using the powerful WildFly 8 architecture.
NetBeans, IntelliJ, and Eclipse allow WildFly to be used for development, deployment, and debugging.
This session will provide an overview of all these features using several live demos.
Format: 30 mins overview of WildFly 8 + 30 mins deep dive on some specific topic(s).JUDCon: Boston 2014

Code-driven introduction to Java EE 7
Speaker: Arun Gupta
Jun 17, 2014
Java EE 7 platform is the latest release of the Java EE platform. WebSocket attempts to solve the issues and limitations of HTTP for real-time communication. A new API is added to the platform build WebSocket driven applications. Processing JSON structures is inherent in any HTML5 applications and a new API to parse and generate JSON is being added to the platform. Longawaited Batch Processing API and Concurrency are now added to build applications using capabilities of the platform itself. In addition, JAX-RS 2 adds a new Client API to invoke the RESTful endpoints, allows asynchronous client/server, and server-sidecontent negotiation. JMS 2 is undergoing a complete overhaul to align with improvements in the Java language. This code-driven talk will provide an introduction to the Java EE 7 platform. Don't miss out on this session to learn all about how to leverage the new and exciting standards in building your next enterprise application.
We are lucky to have Arun Gupta presenting on the new features in Java EE 7. Arun is well known in the Java EE community and was heavily involved with the Java EE 7 specification when he worked at Oracle. Arun now works for Red Hat as Director of Developer Advocacy.
LiveOak: Is that a mobile backend as a service in your pocket?

LiveOak is a new JBoss Middleware project built from the ground up to be mobile friendly and cater to the needs of mobile application developers. Being lightweight and entirely RESTful allows you to hit the ground running in developing your mobile applications with LiveOak.
We will provide an overview of LiveOaks' stack, what we provide OOTB to enable speedy mobile app dev, how the configuration can be modified, and our RESTful guiding principles. Then move onto an application showing how easily and quickly LiveOak can be integrated to provide the required back end. Lastly we touch on how the platform can be extended with your own services to provide additional RESTful resources.Openshift: The Polyglot Platform as a Service
Speaker: Max Andersen "Max Rydahl Andersen was born and raised in Denmark, worked on health care software systems for some time.
In that work I bumped into this small project called Hibernate and had to fix a couple of things in it to make it useful.
Since then I've been working at Red Hat on Hibernate Core, Hibernate Tools, Seam and now lately JBoss Tools and Developer Studio."Mar 11, 2014
OpenShift is Red Hat's polyglot Platform as a service which allow you to run a large range of services in the cloud. In this talk I will give an introduction to OpenShift, what it offers and how it works. The talk will be in two parts. The first is about OpenShift in general and how to use it from the command line and the web console. The Second part is about how JBoss Developer Studio works with OpenShift and how it both coexist and extend the experience you get with 'plain' OpenShift. This part will focus especially on how well the JavaEE and mobile parts of Developer Studio works with OpenShift. The talk is intended to be practical and guided by attendees question.

Improving Infinispan’s Scalability: A new approach to group communication
Speaker: Ryan Emerson
Nov 15, 2013
Infinispan is a distributed in memory key/value store that aims to be highly available and scalable. Its ability to scale is tightly linked to the underlying order protocol, aka atomic broadcast, used for enforcing serializability.
In this talk I will explore the scaling limits of Infinispan's existing protocol and then propose an alternative approach to designing broadcast systems, that decouples ordering and broadcast.
This talk contrasts our approach with Infinispan's, exploring the design features of our new approach and how they will improve Infinispan's scalability.ThreadSafe
Sep 10, 2013
ThreadSafe is a static analysis product for finding concurrency bugs in multi-threaded Java programs. Such bugs can be difficult to find using conventional testing methods. They may occur randomly due to non-deterministic scheduling behaviour, and can be hard to replicate. ThreadSafe analyses can be from within the Eclipse IDE, and/or in conjunction with the Sonar quality dashboard.
ThreadSafe is developed by Contemplate, a spin-out company from the University of Edinburgh. Following its commercial release, it has been installed by an investment bank that participated in Contemplate's Early Adopter Program, and is under evaluation in others. The design intent is not only to identify the subtle issues which can arise in multi-threaded software development, but also to provide an easy to use user experience which allows the developer to quickly understand the analysis and to take remedial action, where required, with confidence and understanding.
Contemplate will talk about its focus on concurrency, and demonstrate ThreadSafe's analysis of some Open Source examples.Transaction Monitoring and Visualisation
Aug 25, 2013
ACID Transactions are routinely used when applications require strong guarantees as to how atomic operations, involving multiple resources, will perform in the presence of failures, such as system crashes and network disruption. Transactional middleware such as JBoss, combined with application frameworks like Java EE provide the developer with a simple means to add transactional semantics to their applications. Problems can still arise, however, for example poor transactional throughput may manifest when a high volume of transactions rollback, which can have a myriad of non obvious causes.
This talk will explore the current methods of troubleshooting some common transactional issues using JBoss and introduce TxVis: a prototype transaction profiling and visualisation tool. We will discuss the challenges of its development and how it will aid the user in profiling the performance of transactions in their software and quickly isolate some commonly occurring problems.Efficient top-k query processing on distributed column family databases
Speaker: Rui Vieira
Aug 16, 2013
Ranking queries are one of the central topics in the field of Information Retrieval with considerable applications in fields such as analytics.
One of the challenges is to provide solutions which can be adapted to distributed data sources, specifically NoSQL distributed column-oriented databases, and comply to 'user' real-time constraints, especially when dealing with massive amounts of data.
In this talk, we discuss the implementation and challenges for some of the most promising algorithms to address these challenges.
We also analyse their scalability and substantial gains in terms of bandwidth and execution time, as indicated by the experimental results.
