Although curl allows us to quickly test our RESTful web services and it is a developer-friendly tool, it is not exactly user-friendly; we shouldn't expect to have our user enter curl commands in their command line to use our web service. For this reason, we need to develop a client for our services. JAX-RS includes a standard client-side API that we can use to easily develop RESTful web service clients.
The following example illustrates how to use the JAX-RS client API:
package com.ensode.javaee8book..jaxrsintroclient;
import com.ensode.jaxbxmlconversion.entity.Customer;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
public class App {
public static void main(String[] args) {
App app = new App();
app.insertCustomer();
}
public void insertCustomer() {
Customer customer = new Customer(234L, "Tamara", "A",
"Graystone"); ...
