jaxrs-client: JAX-RS Client API example

Author: Rafael Benevides
Level: Beginner
Technologies: JAX-RS
Summary: The jaxrs-client quickstart demonstrates JAX-RS Client API, which interacts with a JAX-RS Web service that runs on JBoss EAP.
Target Product: JBoss EAP
Source: https://github.com/jboss-developer/jboss-eap-quickstarts/

What is it?

The jaxrs-client quickstart demonstrates the JAX-RS Client API which interacts with a JAX-RS Web service.

This client "calls" many POST, GET, DELETE operations using different ways: synchronized, asynchronous, delayed and filtered invocations.

System Requirements

The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform 7.1 or later.

All you need to build this project is Java 8.0 (Java SDK 1.8) or later and Maven 3.3.1 or later. See Configure Maven for JBoss EAP 7.1 to make sure you are configured correctly for testing the quickstarts.

Start the Server

  1. Open a command line and navigate to the root of the JBoss EAP directory.

  2. The following shows the command line to start the server with the default profile:

     For Linux:   EAP7_HOME/bin/standalone.sh
     For Windows: EAP7_HOME\bin\standalone.bat
    

Build and Deploy the Quickstart

  1. Make sure you have started the JBoss EAP server as described above.

  2. Open a command line and navigate to the root directory of this quickstart.

  3. Type this command to build and deploy the archive:

     mvn package wildfly:deploy
    
  4. This will deploy target/jaxrs-client.war to the running instance of the server.

Run the Arquillian Tests

This quickstart provides Arquillian tests. By default, these tests are configured to be skipped as Arquillian tests require the use of a container.

  1. Make sure you have started the JBoss EAP server as described above.

  2. Open a command line and navigate to the root directory of this quickstart.

  3. Type the following command to run the test goal with the following profile activated:

     mvn clean verify -Parq-remote
    

You can also let Arquillian manage the JBoss EAP server by using the arq-managed profile. For more information about how to run the Arquillian tests, see Run the Arquillian Tests.

Undeploy the Archive

  1. Make sure you have started the JBoss EAP server as described above.

  2. Open a command prompt and navigate to the root directory of this quickstart.

  3. When you are finished testing, type this command to undeploy the archive:

     mvn wildfly:undeploy
    

Run the Quickstart in Red Hat JBoss Developer Studio or Eclipse

You can also start the server and deploy the quickstarts or run the Arquillian tests from Eclipse using JBoss tools. For general information about how to import a quickstart, add a JBoss EAP server, and build and deploy a quickstart, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts.

To run the tests in Red Hat JBoss Developer Studio:

  1. You must first set the active Maven profile in project properties to be either arq-managed for running on managed server or arq-remote for running on remote server.
  2. Then, to run the tests, right click on the project or individual classes and select Run As --> JUnit Test in the context menu.

Debug the Application

If you want to debug the source code of any library in the project, run the following command to pull the source into your local repository. The IDE should then detect it.

mvn dependency:sources
