# deltaspike-beanbuilder: Shows how to create new beans using DeltaSpike utilities

> Shows how to create new beans using DeltaSpike utilities.

## What is it?

This project demonstrates a CDI Portable Extension that uses DeltaSpike utilities to create new Beans.

This extension permits the injection of JPA entities by id, without the need to query it. To achieve this, the extension observes the `ProcessInjectionTarget` event and get locates all the injection points that have requested injection by id. In `AfterBeanDiscovery` event, the extension creates `Bean` instances using the `BeanBuilder` utility.

The project contains a very simple JPA entity class, the extension class, the service registration file for that extension and an Arquillian test to verify the extension is working correctly.

It does not contain any user interface; the tests must be run to verify everything is working correctly.

## System Requirements

The application this project produces is designed to be run on WildFly Application Server 13 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 WILDFLY_HOME

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

## Start the WildFly Standalone Server

1. Open a terminal and navigate to the root of the WildFly directory.

2. Start the WildFly server with the default profile by typing the following command.

       $ WILDFLY_HOME/bin/standalone.sh

   Note | For Windows, use the `WILDFLY_HOME\bin\standalone.bat` script.

## Run the Arquillian Tests

This quickstart provides Arquillian tests. By default, these tests are configured to be skipped since Arquillian tests require the use of a container.

Note | The Arquillian tests deploy the application, so make sure you undeploy the quickstart before you begin.

Follow these steps to run the tests.

1. Start the WildFly server as described above.

2. Open a terminal and navigate to the root directory of this quickstart.

3. Type the following command to run the `verify` goal with the `arq-remote` profile activated.

       $ mvn clean verify -Parq-remote

Note | You can also let Arquillian manage the WildFly server by using the `arq-managed` profile, meaning the tests will start the server for you. This profile requires that you provide Arquillian with the location of the WildFly server, either by setting the `JBOSS_HOME` environment variable, or by setting the `jbossHome` property in the `arquillian.xml` file. For more information, see Run the Arquillian Tests.

## Run the Tests in Red Hat JBoss Developer Studio or Eclipse

To run the tests in JBoss Developer Studio, first set the active Maven profile in the project properties to be either `arq-jbossas-managed`, for running on a managed server, or `arq-jbossas-remote`, for running on remote server.

To run the tests, right click on the project or individual classes and select Run As –> JUnit Test in the context menu.

## Investigate the Console Output

Maven prints a summary of the performed tests in the console:

## 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 in Red Hat JBoss Developer Studio or from Eclipse using JBoss tools. For general information about how to import a quickstart, add a WildFly server, and build and deploy a quickstart, 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
