Diagnosing Java applications on the fly with Byteman

Diagnosing Java applications on the fly with Byteman

Production being affected by software issues is always an unwanted scenario. Diagnosing production issues, however, should never be an unplanned activity. Structured testing and QA efforts would ideally prevent any software bugs from entering production. So the dilemma is how to prepare for something unexpected in production that was not considered during the earlier testing and QA phases.

This article discusses Byteman, a tool that leverages the Java Instrumentation API to inject Java code into methods without the need to recompile, repackage, or even redeploy the application.

Modernize your application deployment with Lift and Shift

Modernize your application deployment with Lift and Shift

For many software modernization projects, it’s all about learning to love, lift, and shift. No, wait. It’s all about learning to love lift and shift. The basic idea behind lift and shift is to modernize how an existing application is packaged and deployed. Because it’s not about rewriting the application itself, lift and shift is typically quick to implement.

Modern development environments rely on containers for packaging and deployment. A modern environment also uses a continuous integration / continuous deployment (CI/CD) system that automatically builds, tests, and deploys an application whenever its source code changes.

EclipseCon Europe: Che sessions by Red Hatters

EclipseCon Europe: Che sessions by Red Hatters

EclipseCon Europe is almost here, and many Red Hatters are working furiously to make the show as valuable as possible for attendees. (We’re partly doing it for ourselves as well, of course, because it’s a great opportunity to get the entire Che/Theia community together.)  If you aren’t familiar with Eclipse Che, it’s is a next-generation cloud IDE and developer workspace server for teams and organizations. Theia is an extensible open-source framework to develop multi-language IDEs for the cloud and desktop using state-of-the-art web technologies.

The conference will be held next week on October 22–25 in Ludwigsburg, Germany. Here’s a rundown of what will be offered.

Announcing Red Hat Developer Studio 12.9.0.GA and JBoss Tools 4.9.0.Final for Eclipse 2018-09

Attention desktop IDE users: Red Hat Developer Studio 12.9 and the community edition, JBoss Tools 4.9.0 for Eclipse 2018-09, are now available. You can download the Developer Studio bundled installer, which installs Eclipse 4.9 with all of the JBoss Tools already configured. Or, if you have an existing Eclipse 4.9 (2018-09) installation, you can download the JBoss Tools package.

This article highlights some of the new features in both JBoss Tools and Eclipse Photon, covering WildFly, Spring Boot, Camel, Maven, and many Java-related improvements—including full Java 11 support.

Developer Studio/JBoss Tools provides a desktop IDE with a broad set of tooling covering multiple programming models and frameworks. If you are doing container/cloud development, there is integrated functionality for working with Red Hat OpenShift, Kubernetes, Red Hat Container Development Kit, and Red Hat OpenShift Application Runtimes. For integration projects, there is tooling covering Camel and Red Hat Fuse that can be used in both local and cloud deployments.

Source versus binary S2I workflows with Red Hat OpenShift Application Runtimes

Source versus binary S2I workflows with Red Hat OpenShift Application Runtimes

Red Hat OpenShift supports two workflows for building container images for applications: the source and the binary workflows. The binary workflow is the primary focus of the Red Hat OpenShift Application Runtimes and Red Hat Fuse product documentation and training, while the source workflow is the focus of most of the Red Hat OpenShift Container Platform product documentation and training. All of the standard OpenShift Quick Application Templates are based on the source workflow.

A developer might ask, “Can I use both workflows on the same project?” or, “Is there a reason to prefer one workflow over the other?” As a member of the team that developed Red Hat certification training for OpenShift and Red Hat Fuse, I had these questions myself and I hope that this article helps you find your own answers to these questions.
