Summary: The helloworld-rs quickstart demonstrates a simple Hello World application, bundled and deployed as a WAR, that uses JAX-RS to say Hello.
Target Product: WildFly
Source: https://github.com/wildfly/quickstart/

The helloworld-rs quickstart demonstrates the use of CDI and JAX-RS in Red Hat JBoss Enterprise Application Platform.

The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform 7 or later.

All you need to build this project is Java 8.0 (Java SDK 1.8) or later and Maven 3.1.1 or later. See Configure Maven for WildFly 10 to make sure you are configured correctly for testing the quickstarts.

In the following instructions, replace WILDFLY_HOME with the actual path to your WildFly installation. The installation path is described in detail here: Use of WILDFLY_HOME and JBOSS_HOME Variables.

1. Open a command prompt and navigate to the root of the WildFly directory.

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

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

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

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

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

    mvn clean install wildfly:deploy
   

4. This will deploy target/wildfly-helloworld-rs.war to the running instance of the server.

The application is deployed to http://localhost:8080/wildfly-helloworld-rs.

The XML content can be viewed by accessing the following URL: http://localhost:8080/wildfly-helloworld-rs/rest/xml

The JSON content can be viewed by accessing this URL: http://localhost:8080/wildfly-helloworld-rs/rest/json

1. Make sure you have started the WildFly 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
   

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 WildFly server, and build and deploy a quickstart, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts

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
