jaxws-ejb: An EJB JAX-WS Web Service

The jaxws-ejb quickstart is a working example of the web service endpoint created from an EJB.

What is it?

The jaxws-ejb quickstart demonstrates the use of JAX-WS in Red Hat JBoss Enterprise Application Platform as a simple EJB web service application.

System Requirements

The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform 7.4 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 the EAP_HOME and QUICKSTART_HOME Variables

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.

When you see the replaceable variable QUICKSTART_HOME, replace it with the path to the root directory of all of the quickstarts.

Start the JBoss EAP Standalone Server

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

Make sure you start the JBoss EAP 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 install wildfly:deploy
```

This deploys the jaxws-ejb/service/target/jaxws-ejb-service.jar 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

You can check that the Web Service is running and deployed correctly by accessing the following URL: http://localhost:8080/jaxws-ejb-endpoint/EJB3Bean?wsdl. This URL will display the deployed WSDL endpoint for the Web Service.

Run the Client

Make sure you Install the Quickstart Parent Artifact in Maven.
Verify that the service is deployed properly.
Open a terminal and navigate into the client directory of this quickstart.
```
$ cd client/
```
Type this command to run the client.
```
$ mvn exec:java
```
You should see the following output in the client console.
```
EJB3Bean returning: ejbClient calling
```

Undeploy the Quickstart

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

Make sure you start the JBoss EAP 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 CodeReady Studio or Eclipse

You can also start the server and deploy the quickstarts or run the Arquillian tests in Red Hat CodeReady 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 Red Hat CodeReady Studio or Eclipse to Run the Quickstarts.

For this quickstart, follow the special instructions to Deploy and Undeploy a Quickstart Containing Server and Java Client Projects

To build all of the artifacts, right-click on the jaxws-ejb parent project, and choose Run As –> Maven install.
To deploy the service:
- Right-click on the jaxws-ejb-service subproject, and choose Run As –> Run on Server.
- Choose the server and click Finish.
- This starts the server and deploys the service to the server.
To access the application:
- Right-click on the jaxws-ejb-client subproject and choose Run As –> Java Application.
- Choose the Client class and click OK.
- You should see the following message in the Console tab:
  EJB3Bean returning: ejbClient calling
To undeploy the project, right-click on the jaxws-ejb parent project and choose Run As –> Maven build. Enter wildfly:undeploy for the Goals and click Run.

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

Note

You will see the following informational messages. This is because the source files for these JARs are not available in the Maven repository. The jaxws-ejb-service source files are available in the jaxws-ejb project.

[INFO] The following files have NOT been resolved:
