The tasks
quickstart demonstrates how to use JPA in Red Hat JBoss Enterprise Application Platform.
It includes a persistence unit and some sample persistence code to demonstrate database access in enterprise Java.
It does not contain a user interface layer. The purpose of the project is to show you how to test JPA with Arquillian.
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.
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.
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.
-
Open a command prompt and navigate to the root of the JBoss EAP directory.
-
The following shows the command line to start the server:
For Linux: EAP7_HOME/bin/standalone.sh For Windows: EAP7_HOME\bin\standalone.bat
This quickstart provides Arquillian tests. By default, these tests are configured to be skipped as Arquillian tests require the use of a container.
-
Make sure you have started the JBoss EAP server as described above.
-
Open a command prompt and navigate to the root directory of this quickstart.
-
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.
Maven prints summary of the 8 performed tests to the console.

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.
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
