kitchensink-ear: Using Multiple Java EE 7 Technologies Deployed as an EAR

Author: Pete Muir
Level: Intermediate
Technologies: CDI, JSF, JPA, EJB, JAX-RS, BV, EAR
Summary: The kitchensink-ear quickstart demonstrates web-enabled database application, using JSF, CDI, EJB, JPA, and Bean Validation, packaged as an EAR.
Target Product: JBoss EAP
Source: https://github.com/jboss-developer/jboss-eap-quickstarts/

What is it?

The kitchensink-ear quickstart is a deployable Maven 3 project to help you get your foot in the door developing with Java EE 7 on Red Hat JBoss Enterprise Application Platform.

It demonstrates how to create a compliant Java EE 7 application using JSF, CDI, JAX-RS, EJB, JPA, and Bean Validation. It includes a persistence unit and some sample persistence and transaction code to introduce you to database access in enterprise Java. It is based on the kitchensink quickstart but is packaged as an EAR archive.

Note: This quickstart uses the H2 database included with Red Hat JBoss Enterprise Application Platform 7.1. It is a lightweight, relational example datasource that is used for examples only. It is not robust or scalable, is not supported, and should NOT be used in a production environment!

Note: This quickstart uses a *-ds.xml datasource configuration file for convenience and ease of database configuration. These files are deprecated in JBoss EAP and should not be used in a production environment. Instead, you should configure the datasource using the Management CLI or Management Console. Datasource configuration is documented in the Configuration Guide for Red Hat JBoss Enterprise Application Platform.

System Requirements

The application this project produces is designed to be run on Red Hat JBoss Enterprise Application Platform 7.1 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 for JBoss EAP 7.1 to make sure you are configured correctly for testing the quickstarts.

Use of EAP7_HOME

In the following instructions, replace EAP7_HOME with the actual path to your JBoss EAP installation. The installation path is described in detail here: Use of EAP7_HOME and JBOSS_HOME Variables.

Start the Server

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

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

    For Linux:   EAP7_HOME/bin/standalone.sh
    For Windows: EAP7_HOME\bin\standalone.bat
   

Build and Deploy the Quickstart

1. Make sure you have started the JBoss EAP 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 ear/target/kitchensink-ear.ear to the running instance of the server.

Access the Application

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

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 EAP 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
   

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.

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

2. Open a command prompt 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 verify -Parq-remote
   

You can also let Arquillian manage the JBoss EAP server by using the arq-managed profile. For more information about how to run the Arquillian tests, see Run the Arquillian Tests.

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:

INFO  [org.jboss.as.server.deployment] (MSC service thread 1-3) WFLYSRV0027: Starting deployment of "test.war" (runtime-name: "test.war")
...
INFO  [org.jboss.as.quickstarts.kitchensink_ear.service.MemberRegistration] (default task-102) Registering Jane Doe
INFO  [org.jboss.as.quickstarts.kitchensink_ear.test.MemberRegistrationIT] (default task-102) Jane Doe was persisted with id 1
...
INFO  [org.jboss.as.server.deployment] (MSC service thread 1-2) WFLYSRV0028: Stopped deployment test.war (runtime-name: test.war) in 38ms
....
INFO  [org.jboss.as.server] (management-handler-thread - 22) WFLYSRV0009: Undeployed "test.war" (runtime-name: "test.war")

Server Log: Expected Warnings and Errors

Note: You will see the following warnings in the server log. You can ignore these warnings.

WFLYJCA0091: -ds.xml file deployments are deprecated. Support may be removed in a future version.

HHH000431: Unable to determine H2 database version, certain features may not work

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 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.

For this quickstart, follow the special instructions to build Quickstarts Containing an EAR

1. Right-click on the kitchensink-ear-ear subproject, and choose Run As --> Run on Server.
2. Choose the server and click Finish.
3. This starts the server, deploys the application, and opens a browser window that accesses the running application at http://localhost:8080/kitchensink-ear-web.
4. To undeploy the project, right-click on the kitchensink-ear-ear 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
