2.2. JAX-RS Client

With EAP 7.2+ , the JAXRS 2.1 included the ability to set the timeouts [2]. With this you do not have to use the ResteasyClientBuilder. ResteasyClientBuilder extends the javax.ws.rs.client.ClientBuilder , so if you do need to invoke some non spec method, you can still use ResteasyClientBuilder and call connectTimeout / readTimeout on it.

These old methods on ResteasyClientBuilder were deprecated in favor of the spec methods:

establishConnectionTimeout => connectTimeout
socketTimeout => readTimeout

import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Client;

 Client client = ClientBuilder.newBuilder()
                .connectTimeout(100, TimeUnit.SECONDS)
                .readTimeout(2, TimeUnit.SECONDS)
                .build();

We should clarify the standard way: 'Using the Standard Way to Create a Client' , is the JavaEE /JAXRS spec defined way, which is portable. Using the RESTEasy way is not portable since it depends on RESTEasy.
