Did you enjoy the first ride with Fabric8 and OpenShift v3? There's more a lot more to come. After we got the first WildFly container up and running on Kubernetes, without having to deal with all it's inherent complexity, I think it is about time to start to scale and load balance WildFly.Prerequisites
Make sure, you have the complete Vagrant, Fabric8, OpenShift v3, Kubernetes environment running. I walked you through the installation on Windows (more...)
Have you ever dreamed about running WildFly on OpenShift and leverage the latest Kubernetes features: On Windows? Sounds like blasphemy: Everything about those technologies is screaming GO and Linux. Windows doesn't seem to be the right fit. But I know, that there are many developers out there, being stuck on Windows. Corporate laptops, easy management and whatever reasons the different employers come up with. The good news is, there is a small and brave group (more...)

Need to debug your application? With NetBeans 8.1 (dev) and WebLogic it's very easy to do.
First start your WebLogic server in debug mode. The startup scripts generated for a domain provide an option to start the server in debug mode.
To run in debug mode, set the environment variable "debugFlag" to a value of "true" and start the server.
$ export debugFlag="true"
This launches the server with (more...)
Stoked thatNetBeans 8.1 will have support for deployment to remote WebLogic Server instances.
Sometimes you want to cancel your Integrated WebLogic Server, however, if you do this while a deployment is currently going on, you might run into trouble. The log window will not tell you anymore than a remote deployment failed and that the Application can not be run:
You need to clear some directories in your JDevHome before the application deployment works again. Before clearing the directories, make sure you close JDeveloper.
Go to the folder: (more...)
DevOps is among the hottest topic these days. And the wide range of topics around it makes it hard to actually find a complete description or something that covers everything on a decent granularity. One thing is for sure: One of the most important parts is to deliver the correct metrics and and information for monitoring of the application.Java EE and JMX
The standard way of monitoring Java EE servers is JMX. This is (more...)
The latest Liberty biuldpack update now adds the ability to switch to JRE 1.8 runtime. Given I am now switching to JDK 1.8 for all my projects this has come in very handy, and of course Spring Boot favors JDK 1.8 as well. The default is still JRE 1.7 so to switch to 1.8 set an ENV variable as follows in your manifest.yml as shown below.manifest.ymlapplications:
I didn't really plan for it, but with a conference free month, I had the chance to dig around a little more and show you even more of the Camel on WildFly magic, that the WildFly-Camel subsystem provides.The Business Background
The demo is derived from one on JBoss Demo-Central
by Christina Lin. She demonstrates the use of File and JDBC connectors in Camel and also added the use of Spilt pattern and Exception handling method. (more...)
System integration is a nice challenge. Especially, when you're looking for communication standards and reliable solutions. In today's microservices world, everybody talks about REST services and http-based protocols. As a matter of fact, this will never be enough for most enterprise projects which typically tend to have a much more complex set of requirements. A reasonable solution is a Java Message Service based integration. And while we're not looking at centralized infrastructures and ESBs anymore, (more...)
I've been working with Camel since a while now and I really like it's simplicity. Using it on top of Java EE always was a little bit of a challenge and one of the recent talks I gave about how to do this and the different methods of bootstrapping Camel in Java EE actually proposes to use the WildFly-Camel Subsystem
. In an ongoing series I am going to explore the different ways of doing this (more...)
