  • Advanced Queries on the Infinispan Data Grid

    by Sanne Grinovero

    Infinispan isn't just a scalable key/value grid platform: it simplifies execution of distributed query tasks in Map/Reduce style, and it integrates a powerful indexing engine to run full-text searches and efficiently extract information from your largest data collections. This search engine is based on Apache Lucene and provides its most advanced features, such as stackable result filters, faceting, custom text analysis, ranking and similarity formulas, world-class proven performance and reliability. A power user, who is already familiar with Lucene, can switch the roles and use the Lucene's API directly by using the Infinispan Lucene Directory, a special purpose module designed to create an index stored and distributed on Infinispan. After familiarizing with these concepts we'll have a quick demo starring Hibernate Search to show how different approaches can be combined with simple code and known patterns, but still unlocking all the scalability potential of modern cloud technologies.

    At 10:00am to 11:00am, Monday 31st October

  • Arquillian - The Extendable Enterprise Test Platform

    Arquillian is the missing link in Java EE development. Developers have long had to fend for themselves in the testing stage, burdened with bootstrapping the infrastructure on which the test depends. That's time lost, and it places a high barrier to entry on integration testing. Arquillian tears down that barrier. Arquillian is a container-oriented test framework. It picks up where unit tests leave off, targeting the integration of application code inside a real runtime environment. Just as Java EE 5 simplified the server programming model by providing declarative services for POJOs, Arquillian equips tests with container lifecycle management and enrichment. This talk will go behind the scenes of Arquillian, lift up the curtain and unveil the Extendable Enterprise Test Platform. We'll look at how you can take advantage of the test platforms infrastructure to fit your testing needs. We'll show you how to write extension so you can: - Give your test classes new capabilities - Manipulate the packaging process - Hide testing framework integration complexity - Integrate into the test runners lifecycle - Integrate with existing test runners - Create your own Container

  • Bin packing with Drools Planner: scheduling processes on cloud servers

    by Geoffrey De Smet

    Given a set of servers with different hardware (CPU, memory and network bandwidth) and given a set of processes with different hardware requirements, how can we assign each process to a server and minimize the total cost of all the active servers? This is an "NP complete" bin packing problem. So how do we find an optimal solution in reasonable time? And what if we want to solve it in real-time? This session will walk you through the code, implemented in Drools Planner. It will compare different optimization algorithms by the total cost of their solutions. And it includes demo's of course. JBoss Drools Planner optimizes planning problems, such as employee rostering, appointment timetabling, task scheduling, vehicle routing and bin packing.

    At 10:00am to 11:00am, Monday 31st October

  • BPM(N) using jBPM5 and beyond

    by Kris Verlaenen

    A Business Process Management (BPM) suite offers you the capabilities to better manage and streamline your business processes. JBoss jBPM continues its vision in this area by offering a lightweight process engine for executing business processes in pure Java, combined with the necessary services and tooling to support business processes in their entire life cycle. This allows not only developers but also business users to manage your business processes more efficiently (using a combination of web-based and Eclipse-based tooling). A lot has happened in the BPM area over the last few years, with the introduction of the BPMN 2.0 standard, the increasing interest in more dynamic and adaptive processes, integration with business rules, event processing and other external services (e.g. SwitchYard), mobile BPM, BPM in the cloud (e.g. OpenShift), etc. Kris Verlaenen, the jBPM project lead, will show you how jBPM5 tackles these challenges.

    At 11:15am to 12:15pm, Monday 31st October

  • Extreme Performance and Scalability with Near Caches

    by Galder Zamarreño

    The aim of near caching is to provide a bridge between fast, in-memory, local caching and remote, massively scalable, Data Grids in such way that most recently or most frequently accessed data is quickly available while at the same time, clients still being able to transparently and seamlessly access the remote Data Grid when needed. Due to zero latency access provided for local data and the scalability offered by the possibility of going to a remote Data Grid, it's no wonder that this is one of the most demanded Infinispan patterns. In this talk, Galder will offer a detailed view of the pattern with a look at best practices for deploying it in your own environment. The talk will finish with a demo showing near caching in action!

    At 11:15am to 12:15pm, Monday 31st October

  • Hibernate Puzzlers

    by Patrycja Wegrzynowicz

    Hibernate is an elegant, straightforward, and easy to use framework. This is undeniably true for simple domain models. What about more complex ones? It turns out that in case of complex domain models we usually run into interesting hibernate-related issues relating to performance or correctness. Here, we will present several puzzles from JPA and hibernate to illustrate tricky use cases that have interesting side-effects, lead to incorrect behavior, or impose significant performance overhead. Come and see if you can solve them.

    At 11:15am to 12:15pm, Monday 31st October

  • Elastic SOA on the Cloud

    by Steve Millidge

    We know JBoss Enterprise SOA Platform can deliver huge agility in developing new functionality through service reuse. However if our services become popular they may be subjected to massively increased client load from events we as service owners can not predict.With the massive return on investment gained in deployment of private clouds using technologies such as Red Hat Enterprise Virtualization it is now possible to combine SOA-P with JBoss Operations Network to elastically scale out your Service Deployments in response to real time load increases.

    At 12:15pm to 1:15pm, Monday 31st October

  • Infinispan for Ninja Developers

    by Mircea Markus

    At 12:15pm to 1:15pm, Monday 31st October

  • Java EE in the Cloud

    by Pete Muir

    In this session, Pete will introduce to OpenShift, the first Platform-as-a-Service available for Java EE. He will show you how to run create a new Java EE application and deploy it on OpenShift Express, a free, shared multi-tenant environment made to be as simple as possible to get started quickly. He'll then deploy the same application to Openshift Flex, which gives you dedicated VMs and DevOps control over architecture along with monitoring. Pete will then outline some of the updates coming in Java EE 7 to support multi-tenancy - a key component of any PaaS.

    At 12:15pm to 1:15pm, Monday 31st October

  • BoxGrinder: Your Appliances in the Cloud

    by Marc Savy

    BoxGrinder is a set of tools that help you grind out appliances: preconfigured disk images with the operating system and requisite software ready to run on a selected virtualization platform. With a simple text definition file and a single command BoxGrinder will build a lean appliance from scratch, convert it to a target format, and deliver it to your chosen infrastructure. Virtualization has become almost ubiquitous in modern scalable infrastructures, with traditional dedicated hardware setups being replaced by multi-tenanted virtual environments. This change facilitates many of the beneficial properties of Cloud Computing, key amongst which is the ability to create small, function-specific appliances that enables system components to scale independently. BoxGrinder addresses the key problem of specifying and building such appliances. It manages complexities such as software installation, dependency resolution and remote service interactions on your behalf. Existing methods can an arduously convoluted, with poor repeatability and performance characteristics; wasting time and resulting in slow and bloated appliances. Such factors negate many of the motivating factors for embracing Cloud computing, and this is an obstacle that BoxGrinder is specifically designed to overcome. Coherent and simple to specify and run; yet fast to build and easily customised to any desired level of complexity. In this session we will cover the basic concepts of BoxGrinder, with discussion of techniques and use-cases that illustrate how best to utilise BoxGrinder's powerful feature-set. Finally, we will work through a live example, from text definition to a running virtual appliance.

    At 2:30pm to 3:15pm, Monday 31st October

  • Java EE on Google App Engine: CDI to the Rescue

    by Ales Justin

    Google App Engine (GAE) is among the most popular cloud application platforms today, offering decent service at a low price point or even for free. Unfortunately, however, its Java environment is also fairly restrictive. This session presents several tips and tricks on how to use top Java EE specs—CDI, JPA, JSF2, and Bean Validation, for instance—within GAE's restrictive sandbox while still benefiting from the highly scalable environment it provides and maintaining portability to other Java EE containers. It demonstrates how CDI can be used to abstract from GAE's services and how state-of-the-art testing frameworks such as ShrinkWrap and Arquillian can be made to work with a GAE application.

    At 2:30pm to 3:15pm, Monday 31st October

  • Launching into the future with the jBPM Migration Project

    by Eric D. Schabell

    This session will outline the status of our jBPM migration tooling project. We will take a look at the background of jBPM 3 process projects and how we plan to help you migrate to jBPM5. We will start by providing you with a plan for positioning your existing Enterprise jBPM projects, look at the tooling being created and demo on an actual existing enterprise jBPM project.

    At 2:30pm to 3:15pm, Monday 31st October

  • JPA applications in the era of NoSQL and Clouds - Introducing OGM

    by Hardy Ferentschik

    Clouds are an interesting deployment platform, but managing state in dynamically scalable environments is not an easy task. There exist a whole range of different NoSQL solutions with strong differences in performance, capabilities, reliability, isolation and ease of use. In this talk we discuss briefly the different NoSQL solutions and show where Hibernate OGM fits into the picture. Hibernate OGM (Object Grid Mapper) is built on the robust and proven Hibernate core engine and helps you to port existing JPA (Hibernate) applications to alternative storage engines decoupling application code from a specific NoSQL solution. The project is relatively new and not all JPA features are supported; also only one storage engine is supported at the moment: Infinispan. Hardy and Sanne will explain how OGM is designed, what to expect next and how to plug in your own storage engine. All this is accompanied with a demo showing how easy it is to get started.

    At 3:15pm to 4:15pm, Monday 31st October

  • Seam Forge: From Zero to Java EE in 60 seconds

    by Paul Bakker

    How many times have you wanted to start a new project in Java EE, but struggled to put all the pieces together? Seam Forge is a command line tool that helps you setting up and configuring Maven projects in an incremental way. During this presentation you will see how Forge can be used to setup a full Java EE 6 project. Also plugin writing will be demonstrated.

    At 3:15pm to 4:15pm, Monday 31st October

  • Wide-area Migration with Monterey, AS7, Seam, and jclouds

    by Alex Heneveld

    Applications that span multiple clouds needn't be difficult to write: we'll demo how these technologies use an actor-bean model to make it easy to build even highly complex transactional applications. We'll then show how application mobility allows you to scale and to dynamically optimise placement, moving parts of the application to new locations on a fine-grained basis to reduce latency and improve performance. If you like what you see, learn more at developers.cloudsoftcorp.com, jboss.org, and jclouds.org.

    At 3:15pm to 4:15pm, Monday 31st October

  • Eventual consistency: coming soon in Infinispan

    by Manik Surtani

    Infinispan as a data grid has primarily been focused on strong consistency, giving up partition tolerance in exchange. However, moving forward, Infinispan plans to offer an eventually consistent model too, where users could configure Infinispan to weaken consistency in exchange for greater partition tolerance. This talk discusses some of the ideas around an eventually consistent mode for Infinispan.

    At 4:30pm to 5:30pm, Monday 31st October

  • Portal - Lego set for app development.

    by Boleslaw Dawidowicz

    The true power of portal lies in services and design concepts that are easy to reuse and build on top of them. Those are similar to a lego set - a box with pieces that nicely work and connect together. This presentation will explain what are the key services in portal that you won't need to implement yourself from scratch in your application. You will learn how portals like GateIn support UI development with modern web technologies. You will also discover how portal prevents you from reinvent clustering, application caching, page structure, identity management or a way to migrate from staging to production again and again.

    At 4:30pm to 5:30pm, Monday 31st October

  • TorqueBox - Where Ruby meets CDI

    by Marek Goldmann

    There are now quite a few programming languages available on the Java platform (JVM), which has been the case for quite a while. This allows developers to pick the language best suited to their application's needs without sacrificing the power and stability of the JVM. We're not losing the advantages of the JVM by choosing a language other than Java, but what do we gain? For more expressive JVM languages, we can develop faster, and bring back some of the joy of programming. Ruby is a popular and powerful programming language. It owes its success (and power) to its clean and expressive syntax. Why not take advantage of its power and create a system where pretty applications can be run on a very stable and scalable environment? Meet TorqueBox. TorqueBox is the first real application server for Ruby. It allows you to run multiple applications based on Rack (Rails, Sinatra) on the JBoss Application Server. Big deal you say. In reality TorqueBox is much more. Many enterprise-class services offered by JBoss AS such as messaging (JMS) and scheduled jobs are fully available to applications written in Ruby. It is even possible to inject Java EE 6 components like CDI beans into Ruby. Engine written in EJB, front-end in Rails? And everything clustered? Why not! In this session you'll learn how to connect various Java components (CDI beans, message queues) with a simple Rails application.

    At 4:30pm to 5:30pm, Monday 31st October
