JAX-RS RESTEasy 3 Form to Post application/x-www-form-urlencoded Content Type

By Arvind Rai, March 10, 2015
In this page, we will create a client code using RESTEasy client framework. We will create a form using JAX-RS Form class and data will be posted to web service. The form content type will be application/x-www-form-urlencoded

javax.ws.rs.core.Form

JAX-RS provides javax.ws.rs.core.Form class that represents HTML form with application/x-www-form-urlencoded content type. JAX-RS Form class has param() method using which we add form elements.
Form param(String name, String value)

Client Code

In this example, we are creating a JAX-RS form and adding some form elements and using POST method we are sending data to a web service which will return JSON data.
RESTEasyClient.java
package com.concretepage;
import javax.ws.rs.client.Entity;
import javax.ws.rs.core.Form;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import org.jboss.resteasy.client.jaxrs.ResteasyClient;
import org.jboss.resteasy.client.jaxrs.ResteasyClientBuilder;
import org.jboss.resteasy.client.jaxrs.ResteasyWebTarget;
public class RESTEasyClient {
     public static void main(String[] args) {
	ResteasyClient client = new ResteasyClientBuilder().build();
        ResteasyWebTarget target = client.target("http://localhost:8080/resteasyservice-1/employee/manage/saveform");
        Form form = new Form();
        form.param("id", "333").param("name", "Ram").param("company", "ABCD");
        Entity<Form> entity = Entity.form(form);
        Response response = target.request(MediaType.APPLICATION_JSON).post(entity);
        String value = response.readEntity(String.class);
        System.out.println(value);
        response.close();  
    }
}
