WildFly Elytron

RESTEasy client integration with WildFly Elytron client

We have added a new functionality to the RESTEasy client that allows it to use authentication configuration from WildFly Elytron client.

It is now possible to configure bearer token, SSL context and credentials in Elytron client that RESTEasy client will automatically use when making requests.

Elytron client configuration

No new elements have been added to the Elytron client configuration as all of the mentioned mechanisms were already configurable. Configured credentials will be used for HTTP Basic authentication by default. For more information on how to configure Elytron client take a look at the documentation.

Please note that any configuration that RESTEasy client already had configured will not be rewritten.

RESTEasy client use

It is necessary to have WildFly Elytron client on classpath when the build method of RESTEasy client is called:

import javax.ws.rs.client.ClientBuilder;
import org.jboss.resteasy.client.jaxrs.ResteasyClient;


ResteasyClient client = new ResteasyClientBuilder().build();


ResteasyClient client = (ResteasyClient) ClientBuilder.newBuilder().build();

Make sure you have the following dependency on your classpath:


Note: You can have Elytron client configured either in wildfly-config.xml file or in code like below:

AuthenticationConfiguration context = AuthenticationConfiguration.empty().useName("name").usePassword("pass");
AuthenticationContext.empty().with(MatchRule.ALL, context).run(() -> {
    ResteasyClient client = new ResteasyClientBuilder().build();


An example demonstrating this integration can be found here. In this example, two-way SSL is configured on the server. Additionally, HTTP BASIC authentication is required to connect to the server as well. RESTEasy client uses SSLContext and credentials from Elytron client to successfully connect to the server.

Supply your own security configuration to RESTEasy client

You can also provide your own implementation of the org.jboss.resteasy.client.jaxrs.spi.ClientConfigProvider interface and supply authentication configuration from other source than Elytron client.
