Want insights into how other organizations are building cloud-native applications and microservices? At Red Hat Summit 2018, developers from a number of different companies will be sharing their stories in break-out sessions, lightning talks, and birds-of-a-feather discussions. Learn how they solved real business problems using containers, microservices, API management, integration services, and other middleware.
Join us at Red Hat Summit 2018, to hear speakers from Bell Canada, BMW, BP, Deutsche Bank, InComm, Sabre, SIA, Swiss Railways, USAA, and many more.

The next online DevNation Live Tech Talk will be Thursday, March 15th at 12pm EDT. The topic is Camel Riders in the Cloud presented by Claus Ibsen
Apache Camel has fundamentally changed the way enterprise Java™ developers think about system-to-system integration. It makes it easy to apply enterprise integration patterns (EIP) using simple declarations. The result is a lightweight application that is wrapped and delivered as a single JAR.
In this session, we’ll show you how to apply the best practices from the enterprise integration world to build microservices that are deployed as Linux® containers, running on top of Kubernetes and Red Hat OpenShift. These integration applications will be both cloud-native and cloud-portable.
Register now and join the live presentation at 12pm EDT, Thursday, March 15th.
Note: For those outside of the US, daylight savings time started this week, so the US East coast is now UTC – 4.

Apache Camel empowers you to define routing and mediation rules in a variety of domain-specific languages, including a Java-based Fluent API, Spring or Blueprint XML Configuration files, and a Scala DSL. It also uses URIs to work directly with any kind of Transport or messaging model such as HTTP, ActiveMQ, JMS, JBI, SCA, MINA or CXF, as well as pluggable Components and Data Format options. Apache Camel is a small library with minimal dependencies for easy embedding in any Java application.

In my previous article, Enabling Byteman Script with Red Hat JBoss Fuse and AMQ – Part 1, we found a basic use-case for Byteman scripts with Red Hat JBoss Fuse or Red Hat JBoss AMQ. However, the log file was generated separately and only limited operations were possible. In this article I will show you how to use a Java helper class. By using Java, we get advanced operations to view or modify the content. Also, using java.util.logging allows us to log the statements to fuse.log, avoiding the creation of any other log file.

In a production or customer environment it is not always possible to identify issues by looking at logs, nor is it always possible to setup remote debugging using an integrated development environment (IDE) and remote debug port. Often the issues are specific to the environment and can’t be reproduced. Having byteman scripts can help in these situations to identify issues without actual code changes. Whenever certain java class or logic is invoked, byteman scripts will also be invoked as per defined class and method in the byteman script.

This article would help to configure http2 protocol support for the camel-undertow component.
- Camel’s undertow component use embedded undertow web-container of version undertow-core:jar:1.4.21. This version also supports the http2 connection.
- I have used camel version 2.21.0-SNAPSHOT from upstream https://github.com/apache/camel.
- Also, the curl version to test application using camel-undertow component is 7.53.1. This curl version supports –http2 flag for sending an http2 request.
- I have also used nghttp to test application from linux terminal. However, this article is not about http2 insights.
- For http2 details, I found articles  and  helpful.

In this post, I wanted to address how to configure mKahaDB persistence storage on ActiveMQ for better management and reducing disk usage.
Default configured KahaDB persistence adapter works well when all the destinations (queues/topics) being managed by the broker have similar performance. However, an enterprise solution where several third parties are involved is never the case.
There are multiple queues or topics and different consumers or listeners listening to these queues/topics. Some consumers might be slower than other consumers. This will grow the message store’s disk usage rapidly. Due to this situation and being single KahaDB all store destinations might perform slow.

Red Hat JBoss Fuse is an open source, lightweight and modular integration platform that allows you to connect services and systems across your entire application portfolio. If you’re familiar with Fuse, you’re probably familiar with the Fuse Tooling that comes with Red Hat JBoss Developer Studio.
