RESTEasy is a JBoss / Red Hat project that provides various frameworks to help you build RESTful Web Services and RESTful Java applications. It is an implementation of the Jakarta RESTful Web Services, an Eclipse Foundation specification that provides a Java API for RESTful Web Services over the HTTP protocol.
Moreover, RESTEasy also implements the MicroProfile REST Client specification API.
In this tutorial we will demonstrate how to use a BASIC authentication in your REST Services using RESTEasy on the backend and the DefaultHttpClient on the client side.
Please note: this tutorial uses WildFly legacy security framework (Picketbox). If you want to learn how to secure JAX-RS Services using Elytron Security Framework check this article: Securing JAX-RS Services in WildFly applications
This article will teach you how to handle Exceptions properly in RESTful Web services using JAX-RS API and some advanced options which are available with RESTEasy and Quarkus runtime.
This article is a walk through JAX-RS Client API for testing REST Endpoint using WildFly / JBoss EAP 7 as REST provider.
Jakarta Restful Web Services includes an Interceptor API that allows developers to intercept request and response processing. This allows addressing some advanced concepts like authentication, caching, and compressing without polluting application code. Jakarta Restful Web Services define two broad categories to intercept requests and responses: Filters and Entity Interceptors. Filters are used to modify or … Read more
Since WildFly 20, you can configure RESTEasy through the MicroProfile Config project (https://github.com/eclipse/microprofile-config). The use of MicroProfile Config offers to REST developers a plenty of flexibility in controlling runtime configuration. If you want to read more details about MicroProfile Config API, we recommend checking this tutorial: Configuring Microservices with MicroProfile Configuration In a nutshell, the … Read more
