This article series shows how to get started using modern business logic tooling. These updates start with moving from JBoss BPM to Red Hat Decision Manager and from JBoss BPM Suite to Red Hat Process Automation Manager.
The first lab update showed how to install Red Hat Decision Manager on your laptop. This article highlights the second lab update for Red Hat Process Automation Manager, which shows how to create a new project.
Let’s take a look at the lab, shall we?

I’m heading back to my friends in Scotland to speak at the JBoss User Group (JBug) Scotland next month. It’s a fun group of people who really seem to enjoy working with open source and JBoss software stacks.
First off, on June 6th there will be a wonderful tech talk on application modernization and migration. This is followed by the JBug Scotland hosting a hands-on workshop. Come and get hands-on experience in a workshop showcasing application development in the cloud using containers, JBoss middleware, services, business logic, and APIs.
The events are on June 6th, 2018 from 14:00 onwards and are scheduled as follows.

Elytron is a new security framework that ships with WildFly version 10 and Red Hat JBoss Enterprise Application Platform (EAP) 7.1. This project is a complete replacement of PicketBox and JAAS. Elytron is a single security framework that will be usable for securing management access to the server and for securing applications deployed in WildFly. You can still use the legacy security framework, which is PicketBox, but it is a deprecated module; hence, there is no guarantee that PicketBox will be included in future releases of WildFly. In this article, we will explore the components of Elytron and how to configure them in Wildfly.
The Elytron project covers the following:
- Secure credential storage
In this article, we are going to explore using SSL/TLS in WildFly with Elytron.

This article is about a real problem I faced where the timezone on a Java application server (in my case it was JBoss) changed unexpectedly during the run time of the server. It was hard to find any pattern or the reason for the change, as it was triggered by a HTTP request. To debug this scenario, I used the Byteman tool and injected the script into the JVM. This helped me to identify the root cause of the issue and come up with a few Do’s and Don’ts for a shared JVM (like on Java application servers).
Any application server is considered a shared JVM. There are multiple applications deployed on the JVM and they share the same resources. In such a scenario, there are some precautions which need to be taken care of. One of them is dealing with the JVM’s timezone.
Byteman is a tool that makes it easy to trace, monitor, and test the behavior of Java applications and the JDK runtime code. It injects Java code into your application APIs or into Java runtime methods without the need for you to recompile, repackage, or even redeploy your application. Injection can be performed at startup or in running code.

Cloudera Impala is a tool to rapidly query Hadoop data in HBase or HDFS using SQL syntax. You can use Red Hat JBoss Data Virtualization to query that same data via Impala to take advantage of its optimization. You can also combine that data with other data sources in real time. The goal of this guide is to import data from a Cloudera Impala instance, manipulate it, and then expose that data as a data service. This guide includes access to a repository with example scripts, creating a custom base and view model, exposing it as a data service, and finally consuming that data via REST. This is a peer article to Unlock Your Cloudera Data with Red Hat JBoss Data Virtualization.

To be as simple as possible, we will walk through a stand-alone use-case.
Usually, when we require having messaging features in our stand-alone environment, we use full profile for EAP container.
If we have a requirement with clustering functionalities then we prefer to have HA profile but if clustering and messaging both are required then we go for a full-HA profile.
