Do you like JavaEE apps, but wonder how to fit them into a microservices-centric workflow? WildFly Swarm is the answer. I know—“Java” and “microservices” are not words that seem to go together. Java is an old, relatively unsexy programming language. It’s a pretty useful one, but it was created long before the era of Continuous Delivery, containers and microservices. But that doesn’t mean you have to give up on Java if you want to take advantage of microservices. WildFly Swarm...

Recently, I was searching for a solution to configure the security domain of Red Hat JBoss Enterprise Application Platform with the local operating system based user registry so that the application could directly authenticate its users with local operating system users. I understood that it would be difficult to implement a generic solution, as authentication mechanisms are strikingly different between Windows and Unix/Linux. After checking several blogs and forums, I decided to implement this using JPAM for Unix/Linux and Waffle...

Keen to build web applications for the cloud? Get a quick hands-on introduction to OpenShift®, the open source Platform as a Service (PaaS) offering from Red Hat®. With this practical guide, you’ll learn the steps necessary to build, deploy, and host a complete real-world application on OpenShift without having to slog through long, detailed explanations of the technologies involved.

In an earlier article, Debugging Java Applications using the Red Hat Container Development Kit , it was discussed how developer productivity could be improved through the use of remotely debugging containerized Java applications running in OpenShift and the Red Hat Container Development Kit. Not only does remote debugging provide real time insight into the operation and performance of an application, but reduces the cycle time a developer may face as they are working through a solution. Included in the discussion...

Red Hat JBoss Resource Planner (part of Red Hat JBoss BRMS , the enterprise product based on the upstream OptaPlanner community project) is the leading open source constraint satisfaction solver . A constraint satisfaction solver is a solving engine build around sophisticated optimization algorithms that allows to plan for optimal use of a limited set of constrained resources. Every organization faces scheduling problems: assign a limited set of resources, for example employees, assets, time and money, to build products or...

In this series of article, I will present several ways to deploy an application on an EAP Domain. T he series consists of four parts. Each one will be a standalone article, but the series as a whole will present a range of useful topics for working with JBoss EAP . Part 1: Set up a simple EAP 7.0 Domain (this article) . Part 2: Domain deployments through the new EAP 7.0 Management Console Part 3: Introduction to DMR (...

JBoss BRMS provides a sophisticated and powerful business rules engine. The BRMS rules engine allows an organization, among other things, to: define rules in single, governed, environment. define rules in the domain language (or syntax) of the problem domain. declaratively define rules. It allows to define what to do, not how to do it individually test rules, outside of any application logic. (incrementally) update rules without the need to update and/or restart the application that uses the rules. have better...

In part one of our series, we established the process around creating an Android application using Red Hat’s Mobile Application Platform and adding unit tests. Now, we’ll walk through how to use Jenkins for continuous integration on this app. Pre-requisites for this tutorial RHMAP Instances Jenkins installed on Fedora Android Studio setup on a development machine. The following are the topics covered in today’s post: Setup Jenkins to run Android Unit Test Install Jenkins plugins Install Android SDK and Tools...

Messaging is a critical aspect of integrating systems, and while there are many different messaging platforms and infrastructures, a common request is for "zero loss of messages." From there, the terms "Persistence" and "Durability" often get thrown around, but what do those two things really mean? Persistence At a basic level, persistence means that when failure occurs during message processing, the message will still be there (where you found it the first time) to process again once the failure is...

The dramatic influx of mobile application development has driven many new innovations that make it easier than ever to create compelling, flexible, and secure applications. This two-part series details my work done at Red Hat’s Open Innovation Labs to capture these mobile innovations in a useful, repeatable way. In part one of this two-part series, I break down the steps to create and unit test a native android application using Red Hat’s Mobile Application Platform. In part two, I show...

This year’s middleware keynote address at Red Hat Summit talked about microservices, the power of the pipeline, and how developers and devops can work together to release code to production at a much higher rate. The keynote also demonstrated how releases can be shipped so you can switch from the existing deployment to a new deployment (blue/green deployments), and demonstrated how to roll out a canary deployment to a subset of users to test out new features. (If the canary...

In today's modern world, the need for enterprise integration has never been greater. Companies are looking for ways to reduce the costs of their application infrastructure and one of the ways they are doing that is by extending the lifespan of older legacy platforms. This introduces a number of problems when there is also a need for the implementation of new modern systems as well. Often times it is difficult if not impossible to make these new and legacy systems...

Microservices are standing at the " Peak of Inflated Expectations ". It's immeasurable the number of developers and companies that want to bring in this new development paradigm and don't know what challenges they will face. Of course, the challenges and the reality of an Enterprise company that has been producing software for the last 10 or 20 years is totally different from the start-up company that just released its first software some months ago. Before adopting microservices as an...

One of the common requirements for Java based applications on OpenShift is to have these workloads connect back out to an enterprise database that resides outside of the OpenShift infrastructure. While OpenShift natively supports a variety of relational databases (including Postgres and MySQL) as Docker based deployments within the platform, connecting to an existing enterprise database infrastructure is preferred in many large organizations for a variety of reasons including: Inherent confidence in traditional databases due to in house experience around...

Containerization technology is fundamentally changing the way applications are packaged and deployed. The ability to create a uniform runtime that can be deployed and scaled is revolutionizing how many organizations develop applications. Platforms such as OpenShift also provide additional benefits such as service orchestration through Kubernetes and a suite of tools for achieving continuous integration and continuous delivery of applications. However, even with all of these benefits, developers still need to be able to utilize the same patterns they have...

For the last four years I was focused on evangelizing JBoss BPM Suite. The content I produced , the talks I have given and the articles I published led to many requests for a book focused on JBoss BPM products. This got me to thinking and in early November of 2015 I decided to submit a proposal. Hoping Manning would be open to the idea of a book that was not only focused on developers, but also on architects and...

The process can be consistently executed in the same way.

Just like winter, The Developer's Conference (TDC) and the Red Hat Developers group are arriving at São Paulo from July 5th to July 9th, 2016.

As you would expect, security is a key focus for Red Hat. Secure by default is more than a goal, it is a guiding principle across all product lines. Middleware is no exception and there are some amazing things going on in this space. Divya Mehra and Vikas Kumar of Red Hat walked us through some of the recent innovations, including the recently released Red Hat SSO, product built upon KeyCloak . Derek Walker of SWIFT also spoke about how...

WildFly Swarm 1.0.0.Final was released this week at DevNation. It allows the developer to package his application and a JavaEE runtime in a "fat- jar " file. To execute the application, the developer will only need a Java SE Runtime installed and have access to the "fat-jar". No other downloads or configurations are needed. Besides being a well known (and consolidated) Java EE runtime, WildFly Swarm is also an excellent choice for Cloud-native Java apps through the "built-in support for...

WildFly Swarm is a "Just Enough" Application Server. If you don't need EJB, don't bundle it. Likewise for JPA, JAX-RS, or whatever subsystem. Bringing only the portions of an App Server that you need is the strategy that makes Java EE and the JVM a real contender in the microservices space. Ken Finnigan, Co Founder/Lead of WildFly Swarm, walked us through how easy it is to move a monolith deployment to a WildFly Swarm Microservice. Getting Started Getting started is...
