Deploying projects to Apache Felix, Tomcat, and Karaf in VS Code

Deploying projects to Apache Felix, Tomcat, and Karaf in VS Code

We’re expanding tooling support for containers and servers in different development environments. Our existing VS Code extension, Red Hat Server Connector, only provides functionality for Red Hat servers and runtimes like WildFly, Minishift, Red Hat JBoss Enterprise Application Platform (JBoss EAP), and Red Hat Container Development Kit. In this article, we introduce Red Hat Community Server Connector, the newest addition to our Visual Studio Code (VS Code) extensions.

Community Server Connector makes it easier than ever to deploy, run, debug, and test Open Service Gateway initiative (OSGi), Java EE and Jakarta EE, and other projects targeting diverse servers and runtimes. This new VS Code extension allows you to control Apache Felix, Apache Karaf, and Apache Tomcat with the same user interface (UI) and flexibility that you have in Server Connector. And don’t worry, we’ll continue to enhance Red Hat Server Connector as well.

This article offers a general introduction to Red Hat Server Connector. For a more detailed introduction, see my video demonstration, which includes use cases for Apache Felix, Apache Karaf, and Apache Tomcat.

JetBrains IntelliJ Red Hat OpenShift extension provides debug support for OpenShift components

JetBrains IntelliJ Red Hat OpenShift extension provides debug support for OpenShift components

The 0.2.0 release version of the Red Hat OpenShift extension for JetBrains IntelliJ is now available. You can download the OpenShift Connector extension from the JetBrains Plugins Repository. This release provides a new OpenShift: Debug action to simplify the debugging of OpenShift Components pushed to a cluster. It is similar to features developed for Visual Studio Code and JBoss Tools for Eclipse. OpenShift Connector uses OpenShift Do‘s (odo‘s) debug command under the hood and supports only local Java and Node.js components. This enhancement lets the user write and debug local code without leaving IntelliJ.

This article explains how OpenShift: Debug works and shares the difference between debugging Java and Node.js components in IntelliJ.

Set up Red Hat AMQ Streams custom certificates on OpenShift (update)

Set up Red Hat AMQ Streams custom certificates on OpenShift (update)

As anticipated in the “Additional notes” section of my previous article, starting from Red Hat AMQ Streams 1.4, it is finally possible to use your own custom certificate for encrypting communication between Kafka clients and brokers—without the requirement to provide a CA certificate. The auto-generated and -managed internal CAs will still remain, but only to protect inter-cluster communication.

The user-provided certificate can be used with all listeners that have TLS encryption enabled, such as the route, load balancer, ingress, and NodePort types. In this complete example, we will enable an external route listener for one-way TLS authentication.

Prerequisites

You need to have the following in place before you can proceed:

Red Hat XML language server becomes LemMinX, bringing new release and updated VS Code XML extension

Red Hat XML language server becomes LemMinX, bringing new release and updated VS Code XML extension

A new era has begun for Red Hat’s XML language server, which was migrated to the Eclipse Foundation under a new project name: Eclipse LemMinX (a reference to the Lemmings video game). The Eclipse LemMinX project is arguably the most feature-rich XML language server available. Its migration opens more doors for future development and utilization. In addition, shortly after its migration, the Eclipse LemMinX project and Red Hat also released updates: Eclipse LemMinX version 0.11.1 and the Red Hat VS Code XML extension.

How to use the new Kafka Client API for Kafka-specific message properties in Open Liberty 20.0.0.3

In Open Liberty 20.0.0.3, you can now access Kafka-specific properties such as the message key and message headers, rather than just the message payload, as was the case with the basic MicroProfile Reactive Messaging Message API. Also, you can now set the SameSite attribute in the session cookie, the LTPA, and JWT cookies as well as in application-defined cookies.
