# helloworld-ws: Hello World JAX-WS Web Service

Lee Newson

> The `helloworld-ws` quickstart demonstrates a simple Hello World application, bundled and deployed as a WAR, that uses JAX-WS to say Hello.

## What is it?

The `helloworld-ws` quickstart demonstrates the use of JAX-WS in JBoss Enterprise Application Platform Server as a simple Hello World application.

## System Requirements

The application this project produces is designed to be run on JBoss Enterprise Application Platform Server 7.2 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 EAP_HOME

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

## Start the JBoss EAP Standalone Server

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

2. Start the JBoss EAP server with the default profile by typing the following command.

       $ EAP_HOME/bin/standalone.sh

   Note | For Windows, use the `EAP_HOME\bin\standalone.bat` script.

## Build and Deploy the Quickstart

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

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

3. Type the following command to build the artifacts.

       $ mvn clean package wildfly:deploy

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

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

Review the server log to see useful information about the deployed web service endpoint.

    JBWS024061: Adding service endpoint metadata: id=org.jboss.as.quickstarts.wshelloworld.HelloWorldServiceImpl
     address=http://localhost:8080/{artifactId}/HelloWorldService
     implementor=org.jboss.as.quickstarts.wshelloworld.HelloWorldServiceImpl
     serviceName={http://www.jboss.org/eap/quickstarts/wshelloworld/HelloWorld}HelloWorldService
     portName={http://www.jboss.org/eap/quickstarts/wshelloworld/HelloWorld}HelloWorld
     annotationWsdlLocation=null
     wsdlLocationOverride=null
     mtomEnabled=false

## Access the Application

You can verify that the Web Service is running and deployed correctly by accessing the following URL: http://localhost:8080/helloworld-ws/HelloWorldService?wsdl. This URL will display the deployed WSDL endpoint for the Web Service.

## Undeploy the Quickstart

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

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

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

3. Type this command to undeploy the archive:

       $ mvn wildfly:undeploy

## Run the Arquillian Tests

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

Note | The Arquillian tests deploy the application, so make sure you undeploy the quickstart before you begin.

Follow these steps to run the tests.

1. Start the JBoss EAP server as described above.

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

3. Type the following command to run the `verify` goal with the `arq-remote` profile activated.

       $ mvn clean verify -Parq-remote

Note | You can also let Arquillian manage the JBoss EAP server by using the `arq-managed` profile, meaning the tests will start the server for you. This profile requires that you provide Arquillian with the location of the JBoss EAP server, either by setting the `JBOSS_HOME` environment variable, or by setting the `jbossHome` property in the `arquillian.xml` file. For more information, see Run the Arquillian Tests.

## Investigate the Console Output

When you run the Arquillian tests, Maven prints summary of the performed tests to the console. You should see the following results.

    -------------------------------------------------------

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

When you deploy this quickstart, you are presented with a window that explains there is no user interface for this quickstart and directs you to click on a link to view the WSDL definition. However, the Eclipse browser does not support the display of WSDL definitions. Instead, open an external browser and access the following URL: http://localhost:8080/helloworld-ws/HelloWorldService?wsdl. This URL will display the deployed WSDL endpoint for the Web Service.

## 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
