HelloWorld: Example Using Multiple Java EE 7 Technologies Deployed as an EAR

Author: Pete Muir Level: Intermediate Technologies: EAR, JPA Summary: Based on kitchensink, but deployed as an EAR Target Project: WildFly Source: https://github.com/wildfly/quickstart/

What is it?

This is your project! It is a sample, deployable Maven 3 project to help you get your foot in the door developing with Java EE 7 on JBoss WildFly.

This project is setup to allow you to create a compliant Java EE 7 application using JSF 2.2, CDI 1.1, EJB 3.2, JPA 2.1 and Bean Validation 1.1. It includes a persistence unit and some sample persistence and transaction code to introduce you to database access in enterprise Java.

System requirements

All you need to build this project is Java 7.0 (Java SDK 1.7) or better, Maven 3.1 or better.

The application this project produces is designed to be run on JBoss WildFly.

Configure Maven

If you have not yet done so, you must Configure Maven before testing the quickstarts.

Start JBoss WildFly with the Web Profile

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

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

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

Build and Deploy the Quickstart

NOTE: The following build command assumes you have configured your Maven user settings. If you have not, you must include Maven setting arguments on the command line. See Build and Deploy the Quickstarts for complete instructions and additional options.

1. Make sure you have started the JBoss 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:

---

	jboss-cli
	connect 
	deploy  appp.ear
	
	-----
    mvn clean package wildfly:deploy

4. This will deploy target/HelloWorld.ear to the running instance of the server.

Access the application

The application will be running at the following URL: http://localhost:8080/HelloWorld-web.

http://localhost:8080/HelloWorld-web/index.jsf

1. Enter a name, email address, and Phone nubmer in the input field and click the Register button.

2. If the data entered is valid, the new member will be registered and added to the Members display list.

3. If the data is not valid, you must fix the validation errors and try again.

4. When the registration is successful, you will see a log message in the server console:

    Registering _the_name_you_entered_
   

Undeploy the Archive

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

2. Open a command line 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 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.

NOTE: The following commands assume you have configured your Maven user settings. If you have not, you must include Maven setting arguments on the command line. See Run the Arquillian Tests for complete instructions and additional options.

1. Make sure you have started the JBoss 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 test -Parq-wildfly-remote
   

Investigate the Console Output

You should see the following console output when you run the tests:

Results :
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0

Investigate the Server Console Output

You should see messages similar to the following:

Run the Quickstart in JBoss Developer Studio or Eclipse

You can also start the server and deploy the quickstarts from Eclipse using JBoss tools. For more information, see Use JBoss Developer Studio or Eclipse to Run the Quickstarts

Debug the Application

If you want to debug the source code or look at the Javadocs of any library in the project, run either of the following commands to pull them into your local repository. The IDE should then detect them.

    mvn dependency:sources
    mvn dependency:resolve -Dclassifier=javadoc
