In thi section you will learn how to code MicroServices using Eclipse MicroProfile and WildFly Bootable JAR technology.
WildFly 19 includes support for Microprofile JWT Api. In this tutorial we will see how to set up and deploy a REST Application which uses Microprofile JWT for Role Based Access Control. The application will run on the top of Wildly 19 and uses Keycloak as Identity and Access management service. Today, the most common … Read more
The Microprofile Fault Tolerance specification has been specifically built to make your microservices to common failures like network problems or an IOException. In this tutorial we will learn how to use some patterns like @Timeout, @Retry, @Fallback and @CircuitBreaker policies to drive an alternative result when an execution does not complete successfully. Let’s start from … Read more
This tutorial is about building Microservices applications for WildFly developers. The main objective of this tutorial is to discuss the key challenges and solutions around building Microservices using Enterprise API in the Enterprise application environment. Microservice architecture is one of the most widely discussed and adopted architecture pattern in the modern IT Industry. With the … Read more
Microprofile applications can be used in a large variety of contexts. In this tutorial we will learn how to use its API in the most common runtime environments. Configuring Microprofile API with Thorntail Thorntail offers a modern approach to packaging and running Java EE applications, including just enough of the environment to “java -jar” your … Read more
Microprofile fault tolerance specification is a way for your application to handle the unavailability of a service by using a set of different policies. In this tutorial we will see how we can apply these policies in an application that can be run in Thorntail runtime. Thorntail is a Microprofile compliant environment, therefore you can … Read more
In the second tutorial about monitoring WildFly we will learn how to collect application metrics by applying MicroProfile Metrics API that will show up in WildFly 15 and above. So in the first article Monitoring WildFly with Prometheus we have learned how to install and configure Prometheus so that WildFly metrics can be captured. In order … Read more
The Microprofile Opentracing specification defines a set of API for accessing an OpenTracing compliant Tracer object within the JAX-RS application. The behaviors specify how in/out requests will have OpenTracing Spans automatically created. The API also defines how to explicitly disable or enable tracing for given endpoints. WildFly 14 provides initial support for OpenTracing API and … Read more
In the era of Microservices it is essential to be able to externalize and inject both static and dynamic configuration properties for your services. As a matter of fact, microservices are designed to be moved across different environments, therefore it is essential to have a portable externalization of their configuration. In this tutorial we will … Read more
