Quickstarts

What is it?

This project demonstrates a simple CDI Portable Extension and some of the SPI classes used to complete that task. This particular extension explores the ProcessInjectionTarget and InjectionTarget SPI classes of CDI to demonstrate removing a bean from CDI's knowledge and correctly injecting JPA entities in your application.

A Portable Extension is a user extension to Java EE 6 or above which is tailored to a specific use case which will run on any Java EE 6 or higher implementation. This may be something that the specifications don't support just yet, but could be implemented via a portable extension such as type-safe messages or external configuration of beans.

The project contains very simple domain model classes, an extension class, the service provider configuration file, and an Arquillian test to verify the extension is working correctly.

This quickstart does not contain any user interface. The tests must be run to verify everything is working correctly.

System requirements

All you need to build this project is Java 6.0 (Java SDK 1.6) or better, Maven 3.0 or better.

The application this project produces is designed to be run on JBoss Enterprise Application Platform 6 or JBoss AS 7.

Configure Maven

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

Start JBoss Enterprise Application Platform 6 or JBoss AS 7 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
   

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-jbossas-remote 
   

Investigate the Console Output

Run the tests via Maven (or your IDE) and examine the console output during the test phase.

You'll see four tests run:

Results :

Tests run: 4, Failures: 0, Errors: 0, Skipped: 0

In the server log you'll see a few lines similar to

         INFO  [VetoExtension] (MSC service thread 1-8) Vetoed class class org.jboss.as.quickstart.cdi.veto.model.Car
         INFO  [CarManager] (http--127.0.0.1-8080-2) Returning new instance of Car

That will let you know the extension is working. To really see what's going on and understand this example, please read the source and the tests.

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
