I'm looking at the most popular content on my blog from time to time and try to address your needs the best. So, reading my blog is the one way for my fellow readers to drive the content. Another way is to reach out to me in comments or via email. For today, I am going to revamp my JDBC Realm
example with Primefaces and update it to latest WildFly server.Preparations
First step is (more...)
I've been working my way through some security topics along WildFly 8 and stumbled upon some configuration options, that are not very well documented. One of them is the TLS/SSL configuration for the new web-subsystem Undertow
. There's plenty of documentation for the older web-subsystem and it is indeed still available to use, but here is the short how-to configure it the new way.Generate a keystore and self-signed certificate
First step is to generate a (more...)

Thanks to all the attendees for great questions and the attention.
JDK.io is the two day conference of the Danish Java User Group. The venue is pretty unique as it is the IT-University. Which is an amazing building and a unique atmosphere in the session rooms. Check out their website (more...)
Did you know, that there is a free ebook about OpenShift
? Free, like in free beer? You’ll learn the steps necessary to build, deploy, and host a complete real-world application on OpenShift, without having to read long, detailed explanations of the technologies involved.
Though the book uses Python, application examples in other languages are available on GitHub
. If you can build web applications, use a command line, and program in Java
, Ruby (more...)
The first final version of Hibernate OGM is out
and the team recovered a bit from the release frenzy. So they thought about starting a series of tutorial-style blogs which give you the chance to start over easily with Hibernate OGM. Thanks to Gunnar Morling (@gunnarmorling
) for creating this tutorial.Introduction
Don't know what Hibernate OGM is? Hibernate OGM
is the newest project under the Hibernate umbrella and allows you to persist entity (more...)
You have heard about DevNation before, did you? It is a 3-day technical, open source, polyglot conference for full-stack application developers and maintainers. The inaugural edition was held last year in San Francisco and delivered a promising start. You can find my trip report on this blog
. While I've just been one among others in this incredible speaker lineup, the one things that changed for me working for Red Hat is, that I now actually (more...)
You know, that I am a Java EE guy. And I love looking into what comes up with latest servers. JBoss is working on WildFly 9
these days, and one particular area that always caught my interest is scaling, clustering and failover. So, this is a great chance to look at what the new version of Untertow
will have to offer. And it is my pleasure to welcome Stuart Douglas to my developer interview series. (more...)
The JBoss apiman
project hit its first public milestone release (1.0.0.Final) recently, making it the perfect time to go out and have a look at it! Now that the first public release is out the door, we’re planning on iterating quickly on new features and bug fixes. You should expect to see apiman community releases at least monthly.Getting Started with apiman
So how can you get started with apiman? I’m thrilled (more...)

) who is a Toronto based software engineer with Red Hat. has tens of years of experience working on software projects with different technologies ranging from enterprise and mobile Java to Symbian and Qt C++. He specializes on providing tools and APIs for developers. He works in the JBoss Developer Studio (JBDS) and is focused on the (more...)
At the end of 2014 the AeroGear team
announced the availability of the Red Hat JBoss Unified Push Server on xPaaS
. Let's take a closer look!
The Unified Push Server allows developers to send native push messages to Apple's Push Notification Service (APNS) and Google's Cloud Messaging (GCM). It features a built-in administration console that makes it easy for developers to create and manage push related aspects of their applications for any mobile development (more...)
If one thing survived all the New Year parties, it is Docker. It was hot at the end of 2014 and it looks like it is getting even hotter in 2015. And Red Hat is one of the key drivers behind the adoption of this amazing container technology. This is a short summary blog post about a bunch of resources to get you started with Java EE, WildFly and Microservices on Docker.Get A First (more...)
JBoss Data Virtualization
(JDV) is a data integration solution that sits in front of multiple data sources and allows them to be treated as a single source. Do do that, it offers data abstraction, federation, integration, transformation, and delivery capabilities to combine data from one or multiple sources into reusable and unified logical data models accessible through standard SQL (JDBC, ODBC, Hibernate) and/or web services (REST, OData, SOAP) interfaces.
Yesterday the latest 6.1 Beta (more...)
Just a short head-ups, that there is an interesting and free webinar upcoming with Red Hat's Christian Posta (@christianposta

I can't recall when I started doing those end-of-the-year blog-posts. But it became something that I am really looking forward to do. Getting into the mood of looking back at 12 months, 365.242 days, 8765.808 hours and even more seconds. By the average 6.8 hours of sleep per night, this gives us ~17 hours per day. A decent percentage of this went into my jobs and hobbies. I've always been passionate about what I've (more...)
Camel comes with a bunch of features out of the box. One of them is the Swagger integration. Unfortunately, most of the already-there features heavily rely on Spring. But this should not stop us from using them in plain Java EE 7 applications, because it sometimes is just the more lightweight variant of doing things. But I don't want to start a discussion about this again. Instead, I think that there is a technology choice (more...)
Another confirmation came in. JDK.IO
will be my first stop in 2015. This is the annual conference of the Danish Java User Group (Java Gruppen) and it has been extended this year. Instead of one day it is going to be a full two day conference.
The name is an acronym for Java Denmark Input Output - ie a conference for people who reside and work in Denmark with an interest in the Java (more...)
Java Mission Control
(JMC) enables you to monitor and manage Java applications without introducing the performance overhead normally associated with these types of tools. It uses data which is already getting collected for normal dynamic optimization of the JVM resulting in a very lightweight approach to observe and analyze problems in the application code. The JMC consists of three different types of tools. A JMX browser which let's you browse all available JVM instances on (more...)
Everybody seems to do Docker these days. And the whole topic gets even more attraction with Microsoft committed to integrate it into Windows. As many middleware developers are running Windows, I thought I give it a try myself and also give some more tips along the way about how to build and run images with the least possible amount of struggle with Docker containers, hosts and guests and command line options. Arun did a very (more...)
Adam asked me about that at NetBeans Day in Munich. One part of the JAX-RS Client API isn't fully standardized but still very important looking at today's microservice architectures. I am talking about timeouts here. Adam showed how to set them for Jersey
and I just needed to find out how to do the same with Resteasy
import org.jboss.resteasy.client. (more...)
