helloworld-rs: Helloworld Using JAX-RS (Java API for RESTful Web Services)

The helloworld-rs quickstart demonstrates a simple Hello World application, bundled and deployed as a WAR, that uses JAX-RS to say Hello.

What is it?

The helloworld-rs quickstart demonstrates the use of CDI and JAX-RS in WildFly Application Server.

System Requirements

The application this project produces is designed to be run on WildFly Application Server 13 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 to Build and Deploy the Quickstarts to make sure you are configured correctly for testing the quickstarts.

Use of WILDFLY_HOME

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.

Start the WildFly Standalone Server

Open a terminal and navigate to the root of the WildFly directory.
Start the WildFly server with the default profile by typing the following command.
```
$ WILDFLY_HOME/bin/standalone.sh 
```
Note
For Windows, use the WILDFLY_HOME\bin\standalone.bat script.

Build and Deploy the Quickstart

Make sure you start the WildFly server as described above.
Open a terminal and navigate to the root directory of this quickstart.
Type the following command to build the artifacts.
```
$ mvn clean package wildfly:deploy
```

This deploys the helloworld-rs/target/helloworld-rs.war to the running instance of the server.

You should see a message in the server log indicating that the archive deployed successfully.

Access the Application

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

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

Undeploy the Quickstart

When you are finished testing the quickstart, follow these steps to undeploy the archive.

Make sure you start the WildFly server as described above.
Open a terminal and navigate to the root directory of this quickstart.
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 in Red Hat JBoss Developer Studio or 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.

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
